|“||I am a praetor of the legion. I judge this to be in the best interest of Rome.||”|
–Reyna Avila Ramírez-Arellano to Octavian, in The House of Hades.
Reyna Avila Ramírez-Arellano is a Roman demigod, the daughter of Bellona, younger sister of Hylla, the current Queen of the Amazons, former praetor of Camp Jupiter, and is currently a Hunter of Artemis.
Reyna and her older sister Hylla were born to the war goddess Bellona and Julian Ramírez-Arellano in San Juan, Puerto Rico. Millenia before Reyna and Hylla were born, Bellona declared that the Ramírez-Arellano family would play pivotal roles in many battles.
Hylla described their father, saying that he used to be gentle before Reyna was born. When he came back from the war in Iraq, where he was a soldier, he was never the same. He never got over the thinking about the war, and as Reyna grew up, he changed. He saw enemies everywhere and made their house a fortress.
When he had become so paranoid that he had been reduced to a ghost, or a mania, he tossed a chair at Hylla. Reyna was so angry that she attacked him with an Imperial Gold saber, and not knowing it was Imperial Gold, she vaporized him.
Life on Circe’s Island
Some time later they came to C.C.'s Spa and Resort run by Circe. Their home was destroyed during The Sea of Monsters by Blackbeard, son of Ares and his crew of pirates when Percy Jackson and Annabeth Chase accidentally transformed the pirates back into humans using Hermes' Multivitamins.
Although not specifically mentioned by name, Reyna was one of the female attendants on Circe's Island. When Annabeth and Percy first arrived (as revealed in The Mark of Athena), she brushed Annabeth's hair and helped with her makeover. She was on Circe's island because her sister Hylla had wanted to protect her from war. Hylla however was one of the attendants that Percy and Annabeth met, who happens to have been the one carrying a clipboard. After Annabeth accidentally freed Blackbeard and his crew of pirates with Hermes' Multivitamins, they captured her and her sister until Reyna and Hylla managed to escape after learning how to fight. She is mentioned once by Percy when the latter claims that Carter reminds him of her.
After Leaving Circe's Island
According to Reyna, the pirates destroyed the island and took revenge on Circe. Reyna and Hylla, being daughters of Bellona, learned to use weapons quickly and managed to escape from the island and the pirates after being held captive. Eventually, the two sisters went their separate ways. Hylla joined the Amazons and eventually became the Amazon Queen, while Reyna found Camp Jupiter, and eventually became a Praetor, along with Jason Grace for a time.
As Praetor, new arrivals of the camp are required to meet with her. During this time, Reyna and Jason started to form a close relationship, but Jason soon vanished, forcing Reyna to lead the camp by herself.
Post Second Titanomachy
Shortly after the end of the Second Titan War, Nico di Angelo appeared before Reyna and asked her to allow Hazel Levesque to become part of the Legion, which Reyna accepted. Shortly after Jason's mysterious disappearance, Frank also meets with her and apologized for the acts of Shen Lun, his great-grandfather, who supposedly caused the 1906 San Francisco earthquake. Reyna, however, told Frank to never mention to anyone who his great-grandfather was, for what the campers might think, but she let him into the camp.
When parts of Jason's memory comes back to him, he remembers Reyna as someone really close to him and a good friend and leader, which makes him question how he feels about Piper McLean, who later became his girlfriend.
It would have been around this time that Reyna was pestered by Octavian to hold elections for a new Praetor. She eventually agreed, but only at the Feast of Fortuna. While Octavian began to gain support using bribes and blackmail, Reyna started looking for a suitable substitute for Jason.

When Juno appeared in her true form and presented Percy Jackson as a son of Neptune to Camp Jupiter, Reyna was one of the campers in the area. Reyna sounded like she knew him somehow and looked at him as if she had seen him in her nightmares. She called herself the praetor of the Twelfth Legion and said that she didn't know him, which Percy believed was a lie but was unwilling to argue with her in front of her soldiers. She then orders Hazel Levesque to take him inside so she could interrogate him to find out if he was a new recruit, or an enemy to kill.
Before she interrogates him, she tells Percy that her dogs, Argentum and Aurum (Silver and Gold in Latin respectively), do not like liars, meaning they could sniff out lies. She finds it peculiar that Percy doesn't have any memory other than being trained at the Wolf House with Lupa. She then proceeds to interrogate him, noting that his arrival isn't exactly a good omen due to the fact that the Feast of Fortuna is coming up and that it is a bad omen of the arrival of children of Neptune at Camp Jupiter. Throughout the encounter, she implies that they have met. She then sends Percy to the augur, Octavian, to decide to either let him stay or kill him.
Later through the night, she officially makes Percy a probatio. She then announces that it's time to eat and then go and play the War Games. Reyna acts as the referee for the game, flying around on her Pegasus, Scipio. When the Fifth Cohort manages to break down the defensive teams walls (mostly thanks to Frank Zhang, Hazel Levesque, and Percy) and steal the symbol, Reyna calls the game in favor of the offensive team. Mars then appears on the field and congratulates Frank, claiming him as his son and ordering a quest for him. He then tells Reyna that he was the first person over the wall and should be given the Mural Crown.
The next day, Reyna is leading the Senate meeting to decide what supplies the quest members will receive. Octavian wants to give them nothing as the Giant Army is on the way, and he sees it as a suicide mission. Reyna allows them to use the Roman Navy for their trip to Alaska, which turns out to be a single ship called The Pax, but is unable to give them any other support. Before they leave, she talks to Percy alone and tells him about her past on Circe's Island and how her sister Hylla joined the Amazons. She gives him her ring and says that if he sees her sister, ask her for help, and also offers Percy the position of Praetor at Camp Jupiter.
Hazel and Percy later send Reyna an Iris Message to tell her that Polybotes is on his way. Hazel also jokes that she scared Reyna half to death as Reyna was in the bath at the time. Frank replies that he would have paid to see her face.
When Polybotes' army does arrive, Reyna is seen flying into battle on Scipio and destroying monsters. The Amazons arrive to help Camp Jupiter which overjoys Reyna. Once the battle is over, Percy is lifted into the air as the other campers chant "praetor," including Reyna who grasps his hand in congratulations. During the party to celebrate their victory, Reyna makes a speech welcoming the Amazons and gave her sister a big hug. She then congratulated Percy for becoming a praetor of the Twelfth Legion and gives him a purple toga and medal before removing his probatio neck plate and motions for Octavian to give Percy his SPQR tattoo.
The next day when Percy goes to tell the Senate about the Greek demigods arriving, Octavian wants to blast them out of the sky while Percy says they mean no harm. Reyna takes the middle ground and says she will allow them to land, but she tells everyone to stay on their guard in case it is a trick.

When the Argo II arrives at New Rome, Reyna, Octavian, and the seven demigods going on the quest get together to discuss the Prophecy of Seven. While talking and explaining their sides of the story (Jason talking about the quest to free Hera and Percy talking about his quest to free Thanatos), Reyna quickly discovers Jason and Piper's relationship, which Annabeth can tell made her very upset, but didn't show it. After Reyna allows Jason and Piper to tour the city, Reyna will not allow Percy to do the same with Annabeth, as she wants to talk to Annabeth Chase alone first.
Reyna walks with Annabeth around New Rome, calling Argentum and Aurum to her. While she stops at one of the shops for some hot chocolate, she explains to Annabeth that Minerva takes her vow of chastity very seriously, not even having demigod children at all, unlike Athena. She also asks her if she understood how Athena changes, which Annabeth never considered. Reyna tells her that Athena in her Roman form of Minerva is not a war god, just the Goddess of Wisdom and Crafts. So even if the goddess did have Roman children, they would be artists or advisers. Reyna eventually takes Annabeth to her favorite spot in the city, the Garden of Bacchus. Here, Reyna asks to hear her side of the story to see if she can trust them or not. Annabeth told Reyna how she grew up, meeting Luke and Thalia Grace, her quests at Camp Half-Blood, and even about the camp itself, all of which Reyna listened to.
When Annabeth was finished, Reyna pointed to the shrine of Bellona and explained how when the Romans are at war, they throw a spear in the plot of ground inside. Whenever the Romans felt threatened, they would invade anyone around them, including the Greeks. Annabeth tells her that it doesn't have to be that way and the two camps can work together, which Reyna would like as well, but has her doubts. She also gives Annabeth a warning, as she once before met a child of Athena who went to Rome on a quest. She remembered that he had washed up on Circe's Island in a crazed state, half mad from thirst and heat. He talked about a Mark of Athena and a failed quest in Rome before Circe turned him into a guinea pig. While Reyna didn't know what it meant at the time, after hearing a prophecy by Ella earlier, she feels that it is somehow connected to an old legend passed down by Praetors at Camp Jupiter involving Athena.
Before she can explain more, an explosion erupts in the forum where they were eating and Annabeth believes the giants are attacking again. Reyna, however, saw the shot being fired from the Argo II and thinks that the Greeks have betrayed them. Annabeth claims they haven't and is proven true when her dogs don't attack her. Reyna is still angry and feels that at least one of the crew members of the Argo II is a traitor. They both run back together to try and stop any bloodshed that could be caused by the fighting. After the legionnaires marched on the crew of the Argo II, Reyna ran toward them with her dogs.
After escaping, Octavian began to work the Legion into a frenzy and went on a war path against the Greeks with Reyna powerless to stop him. If she tried and stand in his way, he would claim she had gone soft. Onboard the Argo II, Piper considered turning back and explaining things to Reyna, but Annabeth says that without any proof or knowing what had actually caused Leo Valdez to fire on the Romans, they couldn't do much.
The crew of the Argo II is later attacked by the Roman Legion at Fort Sumter. While Annabeth manages to grab a map at the base, she is confronted by Reyna and her two dogs. Reyna tells Annabeth to come back to Camp Jupiter for trial, where she will be executed painfully, but her death could allow some kind of peace and would be better than the alternative. When Annabeth refuses, Reyna explains that she can no longer stop Octavian and that if Annabeth won't stand trial, Octavian will turn his attention on Camp Half-Blood instead. Annabeth tries to explain to her that if they find Athena Parthenos, they could somehow make peace, but Reyna no longer believes that such an outcome could be achieved. However, Reyna doesn't capture Annabeth and allows her to escape back to the ship, with Annabeth asking her to at least slow down Octavian to give them time. Before Reyna leaves, she tells Annabeth the next time they meet on the battlefield, they would be enemies.
Reyna is later shown in Katoptris in a building in New York, along with Octavian and a few other Roman demigods. She is shown to be staring out the window as the others look at a map of Long Island, deciding on invasion routes.

Annabeth, while in Tartarus, has a dream of Reyna standing on Half-Blood Hill. Reyna speaks to Annabeth, but in Athena's voice: I must stand here. The Roman must bring me. Annabeth believes that the Romans' leader returning the Athena Parthenos to the Greeks might be enough to heal the rift between Camp Jupiter and Camp Half-Blood, and by extension stop the Greek and Roman sides of the gods' personalities from fighting over control.
Reyna later appears in Jason's vision, in which Grover Underwood and Rachel Elizabeth Dare meet with her and Octavian at Camp Jupiter's headquarters in New York. Despite Octavian's attempt to start a conflict, Reyna hears Grover and Rachel out for what they have to say. Rachel gives Reyna a note Annabeth had written and transported to Camp Half-Blood while trapped in Tartarus, which states that Reyna must be the one to deliver the Athena Parthenos. Rachel also reveals Reyna's full name, Reyna Avila Ramirez-Arellano (Grover notes that her initials are RA-RA which annoys her), to show her faith in what Reyna must do. Reyna agrees to do what Annabeth has written, but reminds Rachel and Grover that their camp still attacked Rome and declared war, and requests that they leave.
Reyna then prepares to depart for Greece to find Jason and the Argo II in a place where she knows Jason will stop, to Octavian's anger and shock. Knowing that she will be stripped of her praetorship for traveling across the Mare Nostrum and breaking the ancient laws and that Octavian will be in charge as the Romans' augur, Reyna gives strict orders to Octavian and the legion's centurions not to attack Camp Half-Blood until her return; she departs shortly thereafter with Scipio. Shortly after she leaves, Octavian immediately states that there will be a change in the praetor's plans and that they will move up their invasion of Camp Half-Blood.
Reyna reappears in a vision seen by Leo Valdez while he is on Ogygia, where she and Scipio are attacked by gryphons and venti while flying to Diocletian's Palace in Dalmatia.
A wounded and exhausted Reyna arrives at the Argo II while its crew is attempting to close the Doors of Death and rescue Percy and Annabeth at the House of Hades. Unfortunately, Scipio collapses from exhaustion and from the gryphons' poisoned talons. Reyna tearfully kills the Pegasus with her Imperial gold knife to put him out of his misery and breaks down afterward. She has dinner with the Argo II's crew, and she and Annabeth both joke about Percy and whether or not he would have survived Tartarus without her; she jokingly states that she doesn't think "Percy could find his way out of a paper bag" without Annabeth.
She is impressed at Percy and Annabeth's survival of Tartarus, although Percy is more impressed that Reyna made it all the way to Greece with only a Pegasus as her companion. Reyna initially believes that she will be stripped of her rank for breaking the laws of the legion, although Frank reassures her by saying that great leaders have to break laws and think outside the box, like Caesar when he crossed the rubicon. Reyna is proud when Jason informs her that he relinquished his praetorship to Frank, and believes that Frank is exactly the type of person she needs to help command the legion with. She also agrees with him when he states that their first order when they return should be to load Octavian into a catapult and launch him into the ocean.
Initially unsure of what to do to transport the Athena Parthenos back to Camp Half-Blood, she, Nico di Angelo, and Coach Hedge eventually decide to shadow-travel back to Camp Half-Blood at several hundred-mile intervals, with her and Coach Hedge defending Nico from the monsters who will attack the Athena Parthenos as Nico rests himself to shadow-travel again. She, Nico, and Coach Hedge depart for Camp Half-Blood as the Argo II continues its voyage to Greece.

Reyna, Nico di Angelo, and Gleeson Hedge shadow travel with the Athena Parthenos to Camp Half-Blood. After an embarrassing incident in Albania, the three end up in the sky above Mount Vesuvius during their next shadow travel. Nico is too weak to travel on his own, so Reyna lended him her strength so they could travel away. They landed in Pompeii. When they landed, Reyna explained to Nico and Hedge how she shared her strength. Reyna also learned about the Lemures of Pompeii and encouraged Nico to rest. While he slept, Reyna was shocked by the raw pain he had inside of him, how he had proven himself in many ways, and he put his mission first, despite the heartache and sadness. She now trusted him after she knew the truth, and had a desire to tuck him in, but she chided herself that he was a comrade, not a little brother.
Coach Hedge encouraged Reyna to sleep, and she told Aurum and Argentum to watch the statue and obey Hedge. Reyna had a dream of Camp Jupiter being destroyed, and was shot in the stomach by an arrow by Orion. Reyna’s dream shifted and saw Octavian with the legion, and found out that Octavian had crowned himself Pontifex Maximus. Reyna saw Octavian reinstate Bryce Lawrence as probatio. Reyna also saw Michael Kahale, a son of Venus, try to defend Reyna, but Octavian shut him down. Reyna was soon woken up by Hedge because of the hordes of tourists. Reyna wanted to talk about the dreams to Nico and Hedge, but she couldn’t because Nico was asleep. Reyna also felt guilty about being away from the legion.
Reyna went to the bathroom in Pompeii, and was horrified of the place, since it hit too close to home for her. Reyna was also disappointed she didn’t get to see Croatia with Jason. She accidentally stayed near the dead statues until almost noon, and Reyna worried that they were talking behind her back. The rest of the afternoon was uneventful, and Nico woke up at sunset. Reyna told them about her dreams, and Nico told her it was the giant Orion. When they were about to leave, Coach Hedge got possessed by Gaea, and they fought him, with one of her dogs getting hurt. Reyna controlled ghosts from Diocletian's Scepter to save themselves, and shadow travelled away.
They ended up in Portugal, and she and Hedge watched Nico for 36 hours while he slept. When Nico woke, Reyna was sleeping with her dogs at her feet, and Hedge guarded her. Reyna later ate dinner with Nico and Hedge at a cafe, and learned about Nico’s dreams. Reyna also told them that she didn’t have luck contacting her sister, Hylla. Reyna was concerned for Nico and asked how she could help him, surprising Nico. They were interrupted when they were attacked by Lycaon, and Reyna’s dogs attacked them while she stabbed a wolf in the neck. They then shadow travelled away.
Reyna and the others landed on an Atlantic cruise ship called the Azores Queen, where she shooed kids off of the statue. They then landed in San Juan, Puerto Rico, her old home, near a restaurant called Barrachina. Reyna was very scared, because her biggest fear was ending up back in San Juan. Reyna also didn’t feel self conscious about wanting to protect Nico anymore, and felt that she had a connection to him, wanting him to feel support. Suddenly, Reyna was shot by an arrow and put unconscious, and couldn’t stop that from happening to Nico and Hedge. Reyna woke up tied to a chair with cords with a sack on her head, but managed to get free. Reyna met the Hunters of Artemis and attacked them, asking for the lieutenant, Thalia Grace, but it turned out that Thalia was right in front of her. Thalia told her about Orion, and the whereabouts of Nico and Hedge. Reyna also told her about Jason. Thalia took her to Hylla, and wished her luck.
Reyna met Hylla, and she had complicated feelings towards her, and sarcastically thanked her for being abducted. Reyna listened to Hylla and the Hunters discuss Orion, and Reyna asked if Nico and Hedge were safe. Reyna also asked Hylla to give her a ship to travel the Athena Parthenos, but she declined, saying that an Athena statue would tolerate being transported by honorary daughters of Ares. Their conversation was interrupted when Orion broke in and began attacking. Hylla told Reyna to come with her and they escaped through a secret passage into her old house. Reyna was angry when she found out that Hylla rebought their old home, but Hylla told her there was no time to argue. The two ran into Orion, and Orion taunted Reyna about her love life. The two attacked the giant, until Thalia helped Reyna travel away with Nico and Hedge, while Hylla fought Orion alone. Right before she left, ghosts taunted her about what she did to her father, and suffered a breakdown.
They landed in Buford, South Carolina, where Reyna was mostly silent for two days, and refused to tell Nico about what happened with the ghosts in San Juan. Reyna told Nico and Hedge that it was her fault that they landed there, since their town had a battle with a main general who was a son of Bellona, just like Reyna. Nico encouraged Reyna to talk about San Juan, and Reyna began telling Nico about the ghosts of her family, and in return, learned about Jules-Albert, Nico’s zombie chauffeur, something he never told anyone. Reyna told Nico what happened to her father and cried in guilt, but Nico reassured her, telling her it wasn’t her fault.
Suddenly, Bryce Lawrence interrupted their conversation, and threatened to arrest and kill Reyna for Patricide. Reyna told Bryce that he had no right to arrest her, but he said in times of war, things must be flexible. Redcoats under Bryce’s control seized Reyna, and said he needed to bring Reyna alive for a trial, but not Coach Hedge. Reyna decided to go for the trial, and told Nico he could do what he needed. Bryce threatened Reyna with what Octavian will have planned for her, how her execution will happen, and how he can’t wait for her secret to come out, as he cut her cheek with his pilule. Because of this, Nico’s rage exploded, and he turned Bryce into a ghost as Reyna and Hedge watched im horror, reminding Reyna of what happened to her father. Reyna also saw all of Nico’s deepest secrets and found out about him being gay.
Reyna and Hedge took care of Nico for three days as he slept in a shadow coma. At first, Reyna didn’t know what to think, however, Reyna trusted Nico and he lifted some of her burden, and she cared more about him after seeing who he was inside. Reyna and Hedge also arranged Pegasi to carry the statue to camp. When Nico woke up, Reyna told Nico everything that happened, told him that he was her friend and that she trusted him, that he shouldn’t shadow travel anymore, and made him promise to not turn any more people into ghosts. Suddenly, as Reyna told Nico the Pegasi probably wouldn’t come, the Pegasi came to take them to Camp, with Pegasus himself.
Michael told Reyna he was ordered to arrest her, and Reyna asked on what charge. Michael said he didn’t like it more than she did, but he had to. When Hedge started attacking Michael, Reyna told him not to attack. As Octavian yelled at Michael to arrest Reyna and Nico, Tyson and Ella saved them, and Tyson scooped Reyna in his arm. As Tyson almost attacked Dakota and Leila, Reyna told him not to attack, and said they were just following bad orders. Reyna learned that the two Centurion’s were planning to take down Michael. Reyna ordered Tyson and Ella to take Coach Hedge to Camp to see Mellie give birth, told Nico to sabotage the onagers, and Dakota and Leila to delay the attack on Camp Half-Blood. She also told Leila to not hurt Michael. Reyna said her goodbyes to Nico and shook his hand, telling him it was an honor questing with him, and Nico told her she was the strongest demigod he ever met, and he won’t let her down.
When everyone left, Reyna broke down in tears in Blackjack’s mane, and prayed to her mother, Bellona. Suddenly, Orion appeared in the distance and shot an explosive arrow onto her foot, which would explode in 5 minutes, and pulling it out would make it explode immediately. Another arrow went on Blackjack. Reyna asked Orion what happened to her sister, and she learned she and Thalia were alive. Reyna and Orion talked as the timer went down, with Reyna strangely calm, defending her mother, even after Orion appeared. Reyna even thanked the Athena Parthenos, saying it was an honor being with it. Reyna threw her knife and it pierced Orion’s chest. Reyna fell on her arrow to protect the Pegasi, she was unscathed, and realized Athena had given her a piece of her cloak to protect her, what she does to her chosen heroes. Orion pulled the knife from his chest, and threw it at Reyna, but it shattered on impact with her cloak. Bellona then gave Reyna power, in return for the strength she had lent to people over the years. Reyna used her cloak as a rope and hung it around Orion’s neck, and drowned him to death in the water.
Reyna brought the Athena Parthenos to Camp Half-Blood, and returned the statue to the Greeks as a gesture of peace, with the help of Pegasi, Blackjack, and six Roman eagles circling her. Reyna told the Romans to stand together with the Greeks, and Nico told everyone to listen to her. Gaea suddenly awoke and spoke to everyone, and Reyna yelled to close ranks, making the Romans and Greeks stand together. Reyna yelled orders at the Romans, and when Jason and Piper arrived, Reyna and Piper smiled at each other and spoke, and went into battle side by side. Reyna also ordered flaming arrows be shot at a bunch of ogres. Reyna was also glad to see Frank, and the two united the legion as praetors.
After the battle, Reyna, Piper, and Annabeth became inseparable as they helped the two camps get along, where she valued Piper’s skills as a go-between for conflicts. She and Frank promoted Hazel to Centurion. Reyna stayed at Camp Half-Blood for a few days with the other Romans. One night, Reyna thanked the Greeks at the campfire with Frank, and said she still intended to fight battles, but now, she and the Greeks would fight together. Reyna then pulled Nico out of the shadows into the firelight, and said they have two homes now, and gave him a big hug. The crowd cheered, and Nico didn’t pull away, and blinked the tears from his eyes. Reyna offered Nico to stay at New Rome, but he declined.
On the last day at Camp, Reyna talked to Piper at the dock. Piper told Reyna she did so much for both camps, and wished she got more credit, but Reyna didn’t want attention. Piper also told Reyna she knew about how she shared strength, and Reyna said she’d let her know when she got it back. Piper also told Reyna she was welcome any time at Camp, to take time for herself. Reyna told Piper how Venus had told her that no demigod would heal her heart, and Piper told her that she doesn’t know what it means, but that she is in an incredible person, and she would be there for her. Reyna told Piper she had a way with words, even without Charmspeak, and that she will see her again, and shook hands, a newfound friendship between them.
Between the Series
As she is in her office, Claudia, a Probatio in the Fourth Cohort, emerges from a passage way into a aqueduct saying she was lost and shows her a full trash bag. The daughter of Bellona then tells her to leave.
About a week later she and Frank break up a fight between the first and third cohorts after a couple from the first broke into the Bathhouse for a date to find it filled with dead rats and accused the lifeguard, from the third who had a crush on the girl, of putting them there. They listened to both sides and had both clean up the dead rats. The following day she and Frank cancel the afternoon march to investigate the decompostible bags after they break and animal droppings rain down on the camp. That night during the gladiator matches, the Colosseum floods and she, Frank, and the centurions investigate who the culprit is. The following day after the camp is called to assemble and are ambushed by the ballistas on the watch tower and the camp’s supplies of Ambrosia and Nectar vanished. She and Frank investigative the incidents. After going over the evidence they deduce that Claudia is behind everything and she wants to bring the legacy of Mercury before the Senate but Frank convinces the daughter of Bellona to wait until they have sufficient evidence. A day or two later she tails the legacy of Mercury and reveals herself to Claudia as she sneaks into the aviary. She asks Claudia why she should not arrest her right then and their and she says she has information concerning the fate of camp. When she finds the son of Mars, Blaise and Janice tell them everything and they hear Claudia out. When Frank asks if others are involved she has them come in and she complaints the probatio’s loyalty and approves the plan, only substituting Aquila with Frank.
Nico mentions the daughter of Bellona, saying that she and Frank are busy running the Twelfth Legion Fulminata and Camp Jupiter.
Leo mentions her when wondering how the Romans will react to him.
Reyna and Frank Zhang greet Apollo and Meg McCaffrey as they bring Jason’s coffin to camp with Hazel Levesque, Lavinia Asimov, and Don. After learning of Jason‘s sacrifice, she and Frank announce a state funeral and to complete Jason’s plans for Temple Hill by the weekend. The two allow Apollo and Meg to stay as guests.
During Jason’s funeral, she encourages Apollo to perform the funeral rites. As they are able to light the pyre, Lupa arrives and asks to speak to Apollo alone. When he returns he says he will tell her and Frank about at the senate meeting the following day.
As she takes roll call at the senate house, she calls out Lavinia for talking while she is and chewing gum. After hearing that they can call the gods for help if they find Tarquin’s tomb, she and Frank approve a quest.
The following day, she and Frank learn that in order to have the gods help them, they need to sacrifice one and inform Meg and Apollo. They specify that it has to be the soundless god, and Apollo theorizes that he is blacking out communications between demigods. She suggests a senate meeting, but Frank uses emergency powers to send her, Meg, and Apollo to find the soundless god.
Apollo meets her and Meg just outside camp when Hazel and Frank pull up in a red pickup truck that she drives to Sutro Tower. She talks fondly about Thalia Grace and the hunters of Artemis along the way. When they arrive and hike up to the tower, she asks Apollo why he acts strange around her. He tells her what Venus told him and suggests they start dating, she laughs hysterically and rejects him. When they reach the base she and her dogs inspect the station and find it abandoned. She, Apollo, and Meg start to climb the tower and are attacked by a conspiracy of ravens as they near the second platform. She and Meg scold Apollo for punishing them for telling him that his pregnant girlfriend was cheating on him and having her killed. When Apollo scares them away by singing Dean Martin as badly as he can, they continue. When they reach the platform, they find a shipping container that cancels out all sound close to it. Apollo finds out it is the Plotemic god, Harpocrates, and that he wants Apollo vaporized. She and Meg chastise Apollo for bullying him and think of ways to open the door. She uses her empowerment ability to allow Apollo to rip through the chains, and it succeeds. The three collapse when Harpocrares show them his memories of Apollo bullying him, in response, she shows him her memories of the recent battle. Apollo tells her and Meg to destroy the fasces, ceremonial axes used to represent status, of Commodus and Caligula to both free the silence god and weaken the emperors. When they do Harpocrates tries to vaporize Apollo but they save him by showing memories of how much he changed. After the silence god and The Oracle of Cumae leave the world, the three hear the ravens returning.
They fight them off, with a raven giving her a bald spot, and notice it is sunset and that the emperors have reached San Francisco Bay. Meg creates a beanstalk to get down faster, but she passes out and Reyna and Apollo carry the daughter of Demeter to the truck and hit traffic. Reyna and Apollo talk about him forming a consciousness and asks him to contact Frank via a scroll in the glove compartment. They succeed and find the son of Mars in Caldecott Tunnel preparing something with the legion before they lose connection. They soon hit a roadblock and the daughter of Bellona drives through. Meg wakes up just as an Eurynomos attacks and Reyna has her and Apollo drive for her. When she stabs it, Apollo feels pain and swerves off the road. She is next seen with a broken leg and grimacing in pain with Aurum and Argentum guarding her. When Lavinia arrives with a group of nature spirits who splinted her leg, Reyna scolds Lavinia for desertion. She tries to sit up, but she feels a lot of pain and is eased down again. She is then knocked out with nature magic before she can say more and carried away when they leave.
After the battle, she hobbles over on crutches to confirm Lavinia destroying the Julia Drusilla Yachts was her idea.
After the mass funeral a few days later she walks up to Apollo and Thalia Grace, asking Apollo to walk with her to the Senate House and tells the daughter of Zeus she accepts her offer. As they walk she says that she has alway been pressured into being in a relationship and what Venus said really upset her, and that Apollo’s proposal made her realize this. At the senate meeting, she signs from the legion to join the Hunters of Artemis and agrees to have Hazel Levesque to take her place.
In the morning she and Thalia say their goodbyes to Apollo and Meg before setting out to find the Teumessian Fox .
Reyna is a very strong-willed person. She is very strict with the members of the Twelfth Legion and doesn't like to be questioned. However, the reason she is so strict is because she is determined to protect her family after what happened on C.C.'s Spa and Resort. Because of her past, she does her best to be stoic, doesn't show any signs of weakness around others and keeps up her mature public image to keep up the moral of the camp. She feels that if she ever appears nervous or scared, her emotions will cause the camp to worry as well. Hence, even though she was very much changed by the Giant War at the end of The Blood of Olympus, her exterior doesn't show it, according to Piper McLean.
Reyna is distrustful and dubious of new people or people she feels aren't honest with her, though she becomes slightly more relaxed and friendly with people she trusts and cares about. After Percy tells her his story and her dogs don't attack him (as he didn't lie), she tells him about her past and that she is worried about her sister. However, as Leo notes, Reyna isn't known for being a forgiving person, as she still dislikes him with a fierce passion, even though he didn't intentionally attack Camp Jupiter.
When Jason returns to Camp Jupiter with his girlfriend Piper McLean, this hurts Reyna, but she does her best not show it. It isn't until the Argo II fires on Camp Jupiter that Reyna starts to lose hope. Having felt betrayed by Jason, refused by Percy, and leading the camp all by herself for so long, Reyna lost hope that anything could go right for her and felt completely alone. Outwardly, she still projects the image of a confident, fearless leader; internally, she is tired and weary, as noted by Jason during his vision of her meeting with Rachel and Grover. Despite her internal feelings, she still musters the courage to travel across the Mare Nostrum and retrieve the Athena Parthenos to save both Camp Jupiter and Camp Half-Blood, while sacrificing her pegasus Scipio and potentially sacrificing her rank as well for the good of both camps.
Reyna has a softer side as well, and hates to see others experience internal turmoil, and was therefore determined to support Nico throughout their journey together, after feeling his tremendous internal pain. She is also very accepting of others, and, much to Nico's surprise, Reyna, while very surprised, doesn't judge him after finding out about his crush on Percy and seeing a horrifying display of Nico's rage. Reyna's unconditional acceptance was what most likely gave Nico the courage to finally come out to a very surprised Percy and Annabeth shortly thereafter. She also makes sure to acknowledge his role in saving both camps after Gaea's defeat, which helps Nico finally become accepted by them properly.
She hates people using her full name - "Reyna Avila Ramírez-Arellano". Jason said it once trying to pronounce it and Reyna shot him a murderous look. She feels as if she left that name behind when she left Puerto Rico as a young girl, as it brings back too many unpleasant memories pertaining to her abusive father.
Percy describes Reyna in The Son of Neptune as being about sixteen, with piercing black eyes and glossy black hair worn in a single braid. She is often described as having a regal and beautiful face in Hispanic descent and described as having a gaze as if she could take on any challenge. Percy also describes her as having the 'poise of a sword fighter' as if she was ready to spring in action at any moment. Like all the demigods in Camp Jupiter, she has SPQR branded on her forearm with four bar lines and a crossed sword and torch, the symbol of her mother Bellona. Being a praetor, Reyna wears a regal purple toga decorated with gold medals over her own Imperial Gold armor. In The Blood of Olympus, when Athena gifts her with a portion of her own Aegis, Reyna's purple cloak glitters "as if woven through with filaments of Imperial Gold."
- ADHD: Like most demigods, Reyna possesses inborn supernatural battle reflexes and senses that she uses to analyze the fighting style of her opponent.
- Dyslexia: Reyna may be dyslexic, which makes her brain "hardwired" for Latin instead of modern languages.
- Spanish: Reyna can fluently converse in Spanish, being Puerto Rican by birth.
- Fighting Skills: As a daughter of Bellona, Reyna is naturally skilled in swordsmanship and in hand-to-hand combat. She is very proficient in fighting with her spear or knife and was able to hold her own against the Giant Polybotes, though with the help of Scipio. Reyna was skilled enough to fight off all the monsters across the Atlantic to the journey to the Mare Nostrum. From her time with pirates, Reyna noted that she learned several tricks from them, including fighting with two weapons when fending of an army of earthen ghosts. Her skill is such, that she was able to incapacitate Thalia Grace even while tied to a chair. When aided by the power of Athena and Bellona, Reyna ultimately defeated the very formidable Giant Orion. She has shown that she is skilled with a sword, a javelin, a dagger, and an expert in hand-to-hand combat.
- Superhuman Strength: Being a demigod, Reyna is stronger than the average mortal as shown when she knocked aside Lycaon's overgrown wolves with ease with her knife.
- Superhuman Agility: Being a demigod, Reyna is more agile than the average mortal as shown when she used her javelin to launch herself up like a pole-vaulter with ease, and flipped around Orion's bow.
- Telumkinesis: As a daughter of Bellona, Reyna is a natural weapons expert, understanding how to use weapons faster than most other demigods, and may have some degree of magical control over them.
- Necromancy (limited): Being in the rank of Praetor, Reyna can control dead ghosts and skeletons of ancient Roman Legionnaires, as shown in The Blood of Olympus when she used them to help her, Nico, and Coach Hedge fending off earthen ghosts.
- Empowerment: Reyna can share her strength and courage with others, as she does multiple times with Nico di Angelo in The Blood of Olympus. But she does not like to do so, since Reyna feels they will think that she is controlling them. It is more effective in large groups. As a side-affect, she feels any emotions of those she grants strength to. Her tattoo glows and burns when she uses this ability.
As one of the Hunters of Artemis, Reyna has the following abilities.
- Enhanced Physiology: Reyna is naturally slightly stronger and faster than a regular demigod.
- Zoolingualism: Reyna can communicate with animals loyal to Artemis, such as wolves, hawks, and does.
- Huntress Immortality: Reyna became one of Artemis' Hunters in the end of The Tyrant's Tomb, and as a result she is immortal, unless she falls in battle, chooses to leave, or falls in love.
- Agelessness: Due to being a hunter of Artemis, the daughter of Bellona will never age as long as she is part of the hunt.
- Disease Immunity: As a hunter of Artemis, Reyna is immune to disease.
- Spear-Sword: Reyna has an imperial gold spear as shown during the battle at Camp Jupiter and the Camp Jupiter brochure. It can alternate its form between a spear and a sword, at Reyna's will, much like Ivlivs. Since Ivlives belonged to Jason Grace, former praetor, it is possible that all praetors have a weapon like this.
- Dagger : Reyna also has an Imperial gold dagger that she shows Percy.
- Silver Pocket Knife : A silver pocket knife which Reyna keeps at all times, in case of being attacked by lycanthropes.
- Roman Legionnaire Armor : Reyna wears standard legionnaire armor.
- Satchel: A satchel from the Hunters of Artemis , gifted to Reyna by the Hunter Phoebe. It contains healing potions, tranquilizer darts and a highly portable, well furnished tent.
- Aegis Cloak: When Reyna proves her immense bravery against the Giant Orion, Athena enchants her regular cloak with invulnerability, making it glitter with power.
- Aurum: Reyna's gold automaton guard dog that appears whenever Reyna wishes to see if someone is lying.
- Argentum: Reyna's silver automaton guard dog that appears whenever Reyna wishes to see if someone is lying.
- Scipio: Reyna's pegasus that she rides in the battle at Camp Jupiter. It is nicknamed Skippy by the campers. Scipio gets critically injured after a wild Gryphon attack in the House of Hades and Reyna kills the pegasus to put him out of his misery.
- Guido: After being named Horse Friend by Lord Pegasus, his son Guido "adopts" Reyna.
Reyna and Jason were both praetors at Camp Jupiter. While they were close as friends, Reyna states that she did not have a romantic relationship with Jason, though given time she may have. At the end of The Lost Hero, Jason begins to vaguely remember Reyna. He says he feels guilty for liking Piper when he thinks of Reyna, though he is not sure why. When the Argo II appears in the sky at the end of The Son of Neptune, Reyna looks slightly wistful and tells Percy that she hopes he's right and Jason is on the ship because she missed him.
Reyna is described by Annabeth in The Mark of Athena to feel very upset, her voice sounding "like broken glass", when she found out about Jason's relationship with Piper. Reyna also felt that Jason had betrayed her by befriending Leo, who fired on Camp Jupiter with the Argo II (though the Eidolons weren't acknowledged until later), and it didn't help that Jason escaped with Leo on the very same ship afterwards.
In The House of Hades, Jason stated that he had "let [Reyna] believe they had a future together" and felt guilty that he "hadn't shut her down". Later, Jason briefly wondered if Piper was working some sort of Aphrodite magic on him', as when he mentioned Reyna, he 'couldn't think of anything but Piper'.
In The Son of Neptune, Reyna initially disliked Percy for unexplained reasons. It isn't until she tells him that she lived at C.C.'s Spa and Resort before Percy and Annabeth destroyed it that he realizes why. Later, she invites Percy to become a praetor of the Twelfth Legion as the responsibilities of Camp Jupiter were borne by her alone since the last six months, when her closest friend and co-praetor disappeared. Thus she needs him and tries to tempt him into accepting her offer by telling him that she would prefer him to Octavian, who constantly pesters her for praetor-ship, and that it will draw them closer as "friends," though she may or may not mean romantically. Percy states he already has a girlfriend on reflex, halting her advances on him.
Despite this, Reyna still holds a high level of respect for Percy. She knows that he is a very skilled warrior and she would like someone like him by her side. She also likes him for the fact that he was not only able to save her new home, but was also able to bring her sister to help aid in the battle. In The Mark of Athena, Annabeth is able to tell that Reyna is upset that Percy chose Annabeth over herself when they first meet, not allowing Percy to give her a tour, and instead taking Annabeth herself.
Julian is Reyna and Hylla's father, who was reduced to a mania and vaporized by Reyna. Reyna often feels guilty about this fact.
While she has never met the war goddess, the daughter of Bellona has an undying respect for her mother. During her fight with Orion in the Long Island Sound, Bellona gave the praetor the strength to defeat the giant.
Reyna has a somewhat a difficult relationship with her sister Hylla, queen of the Amazons. They parted ways several years ago, when Hylla joined the Amazons and Reyna the Twelfth Legion. They often disagree, but still love each other very much, despite their many differences.
Since she joined the Hunters of Artemis, all of the hunters are now her adoptive sisters.
When Piper first meet Reyna in The Mark of Athena, she initially prepared to hate her for liking Jason, but came to admire her for not showing her feelings at all, having total control of herself, and acting silently considerate. She is constantly afraid that Jason still has feelings for her, although Jason claims he never did have romantic feelings for Reyna, even in his 'previous' life. Reyna, on her part, was unpleasantly surprised, and additionally jealous of Piper when Jason introduced Piper as his girlfriend, and got visibly upset when Jason asked her if he could show Piper around New Rome. Annabeth mentioned that Reyna was trying to hide her pain and anger inside when talking with her. Piper was also uneasy when Jason asked Piper to talk to Reyna and when he talked about his and Reyna's past quest together. Jason seemed entirely oblivious to both, however.
During The Blood of Olympus, however, the two grow closer, as Reyna begins to address Piper, not Jason (having successfully moved on from her feelings for the son of Jupiter). The two, along with Annabeth and Hazel Levesque, become inseparable, as they help the camps get along after Gaea's defeat. Shortly before leaving Camp Half-Blood, Reyna speaks to Piper, asking her about something the latter's mother, Aphrodite had once told her in Charleston, about no demigod ever being destined to "heal her heart", something that Reyna had never spoken about to anyone before. Piper cheers her up, saying that it need not be a demigod that heals Reyna's heart, hinting at the possibility of her future soul mate being a mortal or a god instead, and in the meantime, promises to always be there for Reyna as a friend. Reyna says that Piper has a way with words, even without Charmspeak, they shake hands, with Reyna claiming that she has a feeling that they'll meet again soon.
As seen in The Son of Neptune, Reyna does not have a good relationship with the legacy of Apollo as Octavian always tries to put her down. She is also shown to be annoyed by Octavian constantly questioning her authority and as Percy put it, when he is in front of the Senate he becomes the powerful one. Whenever the Senate proved of her he would try to make it appear as if the idea was his, much to her annoyance. Otherwise, she treats him equally and with respect.
However, in The House of Hades, Reyna is furious when she learns that Octavian has disobeyed her orders as Praetor and has ordered the Legion to attack Camp Half-Blood with multiple onagers. This outrage is displayed by her agreement with Frank Zhang to load Octavian into a catapult and launch him as far away as possible as their first official act as Co-Praetors. Hence, Reyna does not mourn the death of Octavian at all during the end of The Blood of Olympus.
In The Tyrant's Tomb, the daughter of Bellona mentions that she briefly considered him as a romantic partner.
As seen in The Son of Neptune, Reyna is on neutral terms with Frank. It should be noted, however, that Reyna allowed him to join Camp Jupiter, despite his family history (with his great-grandfather Shen Lun supposedly causing the 1906 San Francisco earthquake). She told Percy that Frank has a good heart, but that he is also hopelessly naive and inexperienced.
However, in The House of Hades, when she learns that Jason has signed over his post as Praetor to Frank, Reyna is pleased, noting that she looks forward to leading New Rome with him. Hence, after Gaea's defeat in The Blood of Olympus, both Reyna and Frank speak privately to Chiron and later address both camps at the campfire, helping both sides finally get along with one another.
The two get along very well after that. In Camp Jupiter Classified: A Probatio’s Journal, Frank and Reyna listen to each other and spend most of their time together as co-praetors. Reyna is willing to listen to Frank when Frank persuades her to not send Claudia to the Senate for trial, saying that there isn’t proof yet. The two also confide in each other, and Frank tells Reyna about when Claudia laughed at him near the Temple of Mars.
In The Tyrant's Tomb, Frank and Reyna greet Apollo and Meg McCaffrey together and agree to help them. Frank also reassures Reyna when she decides to go to Sutro Tower. Reyna is very worried and keeps reminding Frank about things before she left, but she still trusts him and calls him on the way back. Frank is very supportive of Reyna giving up her praetorship and calls her one of her best friends and a great leader and mentor, saying that she can never be replaced.
In The Son of Neptune, it is stated that Reyna thinks Hazel would not be a good leader, due to her being a daughter of Pluto. Reyna is also very strict with her, being sarcastic with her when she is late. She is against a daughter of Pluto even standing for Percy but reluctantly agrees. However, Hazel is willing to help Reyna and asks Hylla Ramírez-Arellano to help her. In The House of Hades, Hazel is uneasy about having Reyna on the Argo II to visit, but Reyna listens to Hazel when she talks about the great things Frank Zhang did.
They seem to have gotten closer by the end of The Blood of Olympus, however, as Reyna and Hazel, along with Annabeth and Piper, become inseparable, as they help both of the camps get along after Gaea's defeat. One thing both of them now have in common is their close relationship with Nico, whom Reyna had befriended during her quest back to Camp Half-Blood.
In The Tyrant's Tomb, the two are very close, and Reyna is willing to hear her out when Apollo and Meg McCaffrey come back with her. Reyna and Hazel also joke together, and Reyna lets Hazel use her truck to practice driving, and they joke about how Hazel didn’t run over Terminus again. Hazel is worried about Reyna during the Battle of San Francisco Bay, and lightly hugs her in relief when she finds out she is okay. The two respect each other and Reyna addresses Hazel as “Centurion Lévesque”.
When the daughter of Bellona retired from the legion to join the Hunters of Artemis, she eagerly accepted the daughter of Pluto as her successor, joining in on the Fifth Cohort chanting her name when they need a new praetor.
Through their relationship is not directly shown in The Son of Neptune, it can be concluded they are on good terms. They have obviously interacted before, with their first encounter being when Nico asks her to accept his sister, Hazel, into the legion. Back in Camp Jupiter, Nico was a Senator and the Ambassador of Pluto, and therefore, possibly involved in the camp's political life along with Reyna. At the end of The House of Hades, Reyna is willing to travel with Nico under very dangerous circumstances, showing that she at least does not doubt the son of Hades' loyalty.
In The Blood of Olympus, the two eventually grow close over the course of their journey. Reyna lends Nico strength to shadow-travel, and, as a result, she learns quite a bit about his past and the tremendous internal pain that he's been harboring. She is horrified at the amount of internal pain and raw anguish (even a portion of which is greater than what she had felt from even her entire legion during the battle against the Giant Polybotes), and is determined to support him, and starts thinking of him as a younger brother in spite of herself.
Nico, on his part, admits to "kind of" liking Reyna. When she was briefly taken away by the Hunters of Artemis, Nico is enraged, since he didn't want them stealing another important person from him, and is relieved to have finally found her again. Nico, however, is worried at how brooding Reyna had become after leaving Puerto Rico, and encourages her talk about what troubles her (much to his own surprise, since brooding was usually his own method of dealing with internal turmoil as well), reminding her of the numerous ghosts of Asphodel, who are unable to speak any longer, due to them never speaking out during their lifetimes, reminding Reyna that her voice is her identity, and that unless she uses it, she is "halfway to Asphodel already." As a result, the two finally open up to one another, as Reyna tearfully describes how she killed her father in Puerto Rico (something she'd never ever told anyone up to that point, since patricide is an unforgivable crime by Roman law), and Nico his issues with his father, how he suffered through Tartarus and the feeling of not belonging at either camp. He appreciates someone finally speaking to him so openly, something he'd only ever experienced with Hazel before. Nico is also quick to comfort Reyna, insisting that it was a mania (with only her father's worst qualities) that she had killed, not her actual father. Also, Reyna is the first person that Nico tells about Jules-Albert, his French zombie chauffeur. Reyna later admits that her telling her dark secret to Nico has lifted some of her burden, and that she trusted him.
Reyna later witnesses him kill Bryce Lawrence and seems horrified at the ferocious display of Nico's infernal powers. At that moment, Nico accidentally generates a "flood of pain and anger" on everyone present, allowing Reyna to finally experience his hardships from his point of view and also see Nico's greatest fears and secrets (including his homosexuality and his crush on Percy). Much to Nico's surprise and relief, however, Reyna, while very surprised at this revelation, doesn't judge him, still accepts Nico as a friend just as he is, without hesitation, and cares for Nico's wounds for three days while he recovers from his encounter with Bryce. Reyna's unconditional acceptance and support was what most likely gave Nico the courage to finally come out to a very surprised Percy and Annabeth shortly thereafter.
In addition, Reyna appears to be in awe of Nico's powers, especially after learning that he also possesses hypnokinetic abilities. She also greatly admires Nico's immense tolerance to both physical and mental pain. Nico, in turn, respects Reyna quite a bit, and by the end of their journey to Camp Half-Blood, he even calls her the most courageous demigod he'd ever meet, and promises to not let her down. Reyna wants to hug Nico in return, but doesn't think the gesture would have been welcome, so she settles for a friendly handshake.
After Gaea's defeat, Reyna tells the two camps about Nico's part in saving them, brings him out of the shadows, gives him a big hug, and Nico tearfully returns it, burying his face in Reyna's shoulder. The crowd of demigods roars with approval in response, indicating that thanks to Reyna, both Camp Half-Blood and Camp Jupiter have finally come to truly accept the son of Hades. Shortly before leaving Camp Half-Blood, Reyna promises Nico that he will always have a place in New Rome, and he promises to visit her, Hazel, and Frank often.
Interestingly, several things that both Nico and Reyna have in common are them both of them fluently speaking a Romance language (Italian and Spanish respectively), them both being the younger of two siblings (both of which were female), their shared tendency to hold grudges (though Nico has improved in this regard considerably), their shared habit of twisting the rings on their hands while deeply thinking, and their unrequited feelings for Percy in the past, but they have both managed to move on since then, while remaining good friends with the son of Poseidon and even becoming friends with Annabeth. Nico and Reyna are also the only non-seven characters to be given points of view in The Heroes of Olympus series.
Though, they have never actually had a full one-on-one conversation, she dislikes Leo with a fierce passion due to the fact that he attacked Camp Jupiter with the Argo II, even though it was not his fault, as he had been possessed by an eidolon. However, Reyna isn't known for being a forgiving person, and so probably still dislikes him. However, on Ogygia, Leo is shown to be concerned for her safety, as he grew all frantic upon seeing the attack by the gryphons on Reyna and Scipio just as the video goes dark. Reyna, on her part, despite her former dislike of him (which she seems to have gotten over by this point), was very saddened by Leo's death in The Blood of Olympus.
Interestingly, one thing both Leo and Reyna have in common is that they both speak fluent Spanish, albeit slightly different dialects (Mexican and Caribbean respectively).
Reyna first meets Annabeth in The Mark of Athena, and seems to respects her as a warrior and treats her as an equal. When the two talk alone, she is eager to listen to everything Annabeth has to say and they seem to get along well, with Annabeth feeling like she could tell Reyna anything. She even told Reyna, the location of Camp Half-Blood in a token of friendship. After Camp Jupiter is attacked because of the Eidolons (framing the Greek demigods), her faith in Annabeth begins to waver. After the two camps start to fight, Reyna sees Annabeth's life as a fair price to pay for some kind of peace between the camps, but respects Annabeth enough to allow her to leave and maybe find another way. She also trusts Annabeth's word enough to travel across the Mare Nostrum to the Necromanteion, endangering her praetorship in the process, in order to bring the Athena Parthenos to Camp Half-Blood to finally heal the rift between the two camps permanently, because of a note written by Annabeth to Reyna while in Tartarus. Towards the end of The House of Hades, Reyna is shown to hug Annabeth, telling her that everything would be okay in the end. Also, they are shown to joke around together. This hints at the beginning of a friendship between them.
They finally reunite in The Blood of Olympus, after the Giants' defeat, just as Gaea had finally awakened. After Gaea's defeat, Reyna and Annabeth, along with Piper and Hazel, become inseparable, as they help the camps get along.
Apollo first hears about the daughter of Bellona from Venus. When Apollo thinks she is pretty, Venus tells him to stay away from her. Later, when he comes to Camp Jupiter, Apollo recognizes her and is instantly attracted to her. At camp, Apollo acts very awkward around her and doesn’t really know what to say to her. Reyna helps Apollo with his quest to become a god again and tells him that he needs to sacrifice a god to summon one.
When Reyna, Meg McCaffrey, and Apollo go to Sutro Tower, Reyna dresses up in normal college clothes and Apollo thinks she almost looks normal. In the car, Reyna talks about how she is writing to Thalia Grace and Apollo asks her if they are in a romantic relationship, which Reyna denies, because they are friends and she is a maiden. Later, Apollo asks her out, and Reyna laughs at him hysterically and says no, embarrassing Apollo. When Reyna finds out about what he did to Koronis and Harpocrates, Reyna is disgusted but knows that he has changed. Reyna even defends Apollo against Harpocrates and shows him the good memories of him, showing his change.
The next day after the Battle of San Francisco Bay, Reyna asks Apollo to walk with him to the Senate House. Reyna thanks Apollo for asking him out, because Reyna now realizes how ridiculous she has been, thinking that she needed a guy, and even admits to Apollo’s horror that she considered Octavian as a romantic partner, and that she is sick of being shipped with people. Reyna then joins the Hunters of Artemis, which Apollo is supportive of wholeheartedly. Reyna says goodbye to him and Meg the next day.
Apollo thinks that Reyna is a capable warrior and that they both respect each other. They are both currently friends.
Thalia and Reyna first meet in The Blood of Olympus, where Thalia kidnaps her in San Juan. Reyna is angry when she first meets her, hitting her with a chair and almost cutting her throat with her knife, demanding to see Thalia. Thalia then tells Reyna that she IS Thalia. Thalia tells Reyna that the Hunters and the Amazons are working together to defeat Orion, and that Reyna is being used as bait for them. They talk and Thalia wishes her good luck when she takes her to Hylla Ramírez-Arellano. Thalia respects Reyna, telling her that Jason called her good and addressing her as praetor, while Reyna also respects her, adressing her as lieutenant. Thalia later fights Orion, letting Reyna, Coach Hedge, and Nico escape.
In The Tyrant's Tomb, it is revealed that Reyna and Thalia have been writing each other for months, and have become close friends. Reyna talks fondly of Thalia, to the point where Apollo asks her if they are dating, which Reyna refuses saying that they are friends and she is an eternal maiden. Later, Thalia visits Camp Jupiter when Diana is summoned, and Thalia asks Reyna to join the Hunters. When the two see each other, they hug and are happy to meet. Reyna is also the one to tell her that Jason Grace died.
After the mass funeral of Jason, Reyna tells Thalia that she accepts her offer to join, and walks with her and Apollo to the Senate House, where she announces that she is joining the Hunters of Artemis. Reyna then jokes to Thalia about how joining the hunters is a vacation, where Thalia refuses, saying that they have to hunt the Teumessian Fox. At some point, Reyna tells Apollo about how she hates being shipped with Thalia as a couple.
Reyna is very annoyed with the daughter of Terpsichore at first, being annoyed when she abandons her post and chews gum, and Lavinia thinks she is too strict. When Lavinia tries to tell Reyna what happened when they were attacked by Eurynomos, Reyna silences her, having Apollo tell the story instead. At the senate meeting two days later, Reyna reprimands her for talking too loud to Apollo and chewing gum. When Reyna asks for volunteers to find Tarquin’s Tomb, Lavinia pops her gum too loud, causing Reyna to have her volunteer. Lavinia is angry at Reyna after that, saying that she thinks chewing gum is a crime.
Later, when Apollo, Meg, and Reyna return from Sutro Tower, Reyna sprains her ankle in a Target Parking Lot, Lavinia pretends to be a first responder and helps Reyna, moving her to the woods. Reyna scolds her for deserting, but Lavinia tells Reyna that she has a plan, then knocks her out. It is revealed later that Lavinia and Reyna blew up the Julia Drusilla Yachts, which Reyna confirms that was part of her orders to Lavinia, and lies saying that she never deserted, defending her.
The son of Bacchus was very loyal to Reyna and respected her position as praetor, and reported to her when Reyna ordered all centurions to stand by her when the Argo II arrives. Dakota also defends the legion at Fort Sumter and is at the Empire State Building with her when she meets up with the Greek Demigods.
In The Blood of Olympus, he, Leila, and Michael Kahale come to arrest Reyna, but Dakota keeps winking at her, confusing Reyna because she thinks he might be twitching from too much Kool aid. After Tyson and Ella knock out Michael, they call Dakota a bad Roman, but Reyna defends him saying that he is good, just following bad orders. Dakota then tells Reyna that he was trying to tell her that he and Leila were going to switch sides and take down Michael. Reyna orders Dakota to lead cohorts in her orders, which Dakota agrees to. Dakota goes to Camp Half-Blood, and he and his cohort swear loyalty to Reyna against Octavian, causing Octavian to threaten to arrest him for treason. Dakota returns to Camp Jupiter with Reyna.
Leila and Reyna seem to be on good terms. In The Blood of Olympus, Reyna defends Leila when Tyson and Ella call her a bad Roman, but Leila says that she and Dakota were going to switch sides to take down Michael Kahale. When Reyna tells her and Dakota to have their cohorts follow them and fight against Octavian, Dakota worries about being arrested for treason while Leila says that Reyna is still praetor and that it’s her orders. Leila pledges loyalty to Reyna at Camp Half-Blood, causing Octavian to threaten to arrest her for treason.
Coach Hedge and Reyna are close friends, and the two and Nico di Angelo brought the Athena Parthenos from Epirus to Camp Half-Blood. The two help heal Nico di Angelo together and they care about each other a great deal, presumably talking to each other a lot while Nico rested. Reyna worries a lot about Coach Hedges well being, and demands the Hunters of Artemis to tell her where Nico and Coach Hedge are, and is relieved when they are alive. Reyna is also presumably grateful for Coach Hedge for being there when she had to put down Scipio. He is also driven to tears when Guido tells him that he and the Pegasi helped them because of Reyna's relationship with Scipio.
