Reyna Ramírez-Arellano

Reyna is a Roman demigod daughter of Bellona, younger sister of Hylla, and Praetor of Camp Jupiter.

History
Reyna and her older sister Hylla were born to the goddess Bellona. Reyna was originally from Puerto Rico. They used to live at C.C.'s Spa and Resort ran by Circe. Their home was destroyed during The Sea of Monsters by Blackbeard and his crew of pirates when Percy and Annabeth accidentally transformed the pirates back into humans using Hermes' multivitamins. According to Reyna, the pirates destroyed the island and took revenge on C.C. (Circe). Reyna and Hylla, being daughters of Bellona, learned to use weapons very fast and managed to escape from the island and the pirates after being held captive. Eventually, the two sisters went their separate ways. Hylla went and became an Amazon Queen, while Reyna found Camp Jupiter and eventually became a praetor, along with Jason Grace at a time.

As praetor, new arrivals of the camp are required to meet with her. Nico appeared before Reyna and asked her to allow Hazel to become part of the Legion, which Reyna accepted. Frank also met 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, but she let him into the camp. When Percy arrived at Camp Jupiter, she pretended not to know him, even though she saw him at C.C.'s Spa and Resort. During her time as praetor, she and Jason started to form a close relationship, but Jason vanished forcing Reyna to lead the camp by herself, after which she was pestered by Octavian, a descendant of Apollo, to hold elections for a new praetor. She agreed to, but only at the Feast of Fortuna, but it never happened because during the battle that day, Percy was raised to praetor.

The Sea of Monsters
Although not specifically mentioned, was one of the female attendants on Circe's Island. When Annabeth and Percy first arrived, she brushed Annabeth's hair and helped with her makeover. She was on Circe's island because her sister Hylla 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 freed Blackbeard and his crew of pirates, Reyna managed to escape with her sister after learning how to fight.

The Lost Hero
When part of Jason's memory comes back to him, he remembers Reyna to be someone really close to him, making him question how he felt about Piper.

The Son of Neptune
When Juno appeared in her true form and presented Percy 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 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 (Silver) and Aurum (Gold), do not like liars. 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. 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, Hazel, 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. 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 manages to at least give them a ship (The Pax) to use to sail to Alaska. 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, to ask her for help.

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.

The Mark of Athena
When the Argo II arrives at New Rome, Reyna 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 want's to talk to Annabeth alone first.

Reyna walks Annabeth around the city, 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, but the god 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 Castellan 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 explains how when the Romans are at war, they place 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. 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 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 person in Annabeth's crew 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. On board 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 are 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 piece, 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 met on the battle field, 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 invasion routes.

Personality
Reyna is a very strong willed person. She is 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. She is untrusting of new people or people she feels aren't honest with her. She seems to have a softer side when alone or with people she trusts. 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. She is also noted to be stoic to some extent.

When Jason returns to Camp Jupiter with his girlfriend Piper, this hurts Reyna, but she does not show it. It isn't until the Argo II fires on Camp Jupiter that Reyna starts to loose 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.

Appearance
Percy describes Reyna as being about sixteen, with piercing dark eyes and glossy black hair worn in a single braid (though her description is different than her actual picture). Like all the demigods in Camp Jupiter, she has SPQR branded on her arm 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 golden armor.

Abilities
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 hard-wired for reading and speaking Latin instead of modern languages.

Demigod Abilities
Weapons Expert: Being the daughter of Bellona, Reyna is a natural weapons expert, understanding how to use weapons faster than other demigods

Jason Grace
Reyna and Jason were both Praetors at Camp Jupiter. While they were close as friends, Reyna states that she did not have a 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 Reyna looks a little wistful and tells Percy that she hopes he's right and Jason is on the ship because she missed him.

Percy Jackson
Reyna originally 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, because she feels like she needs him and it will draw them closer as "friends," though she may mean romantically, but Percy states he already has a girlfriend. Later, during the battle, when she sees her sister Hylla, she glances at Percy with a look that says: I could hug you right now.

Frank Zhang
She is on neutral terms with him. Reyna allowed Frank to join Camp Jupiter despite his family history. She told Percy that Frank has a good heart, but he's hopelessly naive and inexperienced.

Octavian
Reyna doesn't have a good relationship with him, as he always tries to put her down. She is also shown to be annoyed by Octavian questioning her authority and as Percy put it, when he is in front of the senate he becomes the powerful one. Otherwise, she treats him equally and with respect.

Hazel Levesque
Although, Reyna and Hazel rarely interacted during the book, it's presumed that Reyna is on good terms with her. However, it is stated that she thinks Hazel would not be a good leader due to her being a daughter of Pluto.
