Luke Castellan

Luke Castellan is a son of Hermes and May Castellan.

Early Life
Luke is a son of Hermes. Not much is known of his early life, but when he was about nine, Luke ran away from his mother's home in Westport, Conneticut, due to her unstable mental condition brought about by the curse of Hades, causing her to rant and frighten him. Later on, he met Thalia. They paired up, and eventually ran into Annabeth, a plucky seven year old. Luke liked her for her courage, and gave her his knife, and promised that he wouldn't fail her like her family had failed her. This was the moment that Luke later envisioned to tie him to his human life.

They all wandered around, trying to survive and avoid monsters. It is implied that he began to forge a romantic relationship with Thalia at this time.

When Thalia got injuried by a monster, Luke took Thalia and Annabeth to his mother's house, to bandage up her leg. There, Luke met Hermes, his father, for the first time. Luke was angry with his father, and demanded at why he had never showed up when he prayed to him. Hermes inadvertly reveals he knows Luke's fate, and Luke eagerly asks about it, but Hermes refuses to tell him. Luke then tells his father that he couldn't possibly love him if he won't tell him, and leaves angrily.

After that, Luke acted like he had something to prove, according to Annabeth. They got into more skirmishes because of his recklessness, and then they ran into the Hunters. They asked Thalia to join, and she refused, saying she couldn't leave Luke. Zoë hauntily told her that Luke would let her down, and that caused Thalia to resent and dislike the Hunters.

Eventually they all ran into Grover Underwood. Together, the quartet traveled to Camp Half-Blood but were chased by monsters from Hades. They would have escaped, except for the fact that a cyclops stopped them so that monsters could catch up. The cyclops held Thalia, Luke and Grover in the air to direct the monsters in their direction, but Annabeth saved them by stabbing the Cyclops in the foot. Thalia sacrificed her life so that Luke, Grover and Annabeth could get into camp without being killed (Thalia was actually transformed into a tree by the gods to save her life). From that point on, Luke lived at camp all year round, likely trying to reconcile with Thalia's "death", all the while slowly falling into darkness.

Allegiance to Kronos
Once, Luke was offered a quest during his years at Camp Half-Blood by his father Hermes: to seek a Golden Apple at the Garden of Hesperides. He was honored by this offer, but later began to question it, as it was done before by Hercules. He went on this journey, but failed and was scarred by the dragon guarding the tree, Ladon. He returned to the camp and according to his words, was treated with "pity" by his comrades. It was then that he began to hold a grudge against Olympus and his father, Hermes, who he began to feel didn't love him due to having rarely seen him.

He was later contacted in his sleep by Kronos, lord of the Titans. The nature of this encounter is unknown, but he was convinced to join Kronos's cause out of a desire for revenge. He was assigned to steal the Master Bolt, Zeus' primary weapon, and the Helm of Darkness, Hades's godly weapon, in order to start a war between the gods.

On a camp field trip to Mount Olympus, he made his move. While the other campers and counselors were asleep he entered the throne room and stole the Master Bolt and the Helm of Darkness, as in their arrogance, the Olympians were off guard. They later discovered the theft and went to search for the thief. Ares found Luke and fought him. According to Luke, he would have won, but underestimated his opponent and was outmatched. However, he managed to save himself by speaking in Kronos's words that if the Master Bolt was successfully stolen, there would be a full scale war. Ares was awed by this, and spares Luke, but takes the Bolt and the Helm with him. Ares later fights Percy Jackson, and he acquires the 2 items. Luke then managed to make it safely back to Mount Olympus before anyone noticed his absence, therefore succeeding in his mission.

Another Resort
Although Luke succeeded in his mission, his failure to defeat Ares cost him dearly. Kronos punished him with nightmares, and Luke swore never to fail the malevolent Titan again. This would also cause him to fear Kronos greatly for many of his later years.

He is then told that another camper would be coming to Camp Half-Blood who would take the hidden items of the Gods that were stolen down to Tartarus, therefore ensuring that there would be a war. Luke remembered this and found this camper in the form of a twelve-year old boy named Percy Jackson.

A Scheme in Action
Knowing that Percy Jackson was the boy that Kronos was talking about, Luke befriended the boy and was successful in earning his trust. He welcomed him into the Hermes cabin (where children who haven't been claimed yet go), trained him in sword combat (his skills amazing Percy), and provided him moral support for being a newcomer.

One night after a Capture the Flag game, he summoned a hellhound to attack Percy in an attempt to make Chiron, the camp activities director, believe that the camp wasn't safe for Percy. Therefore, Chiron sent Percy, along with Annabeth and Grover, to find the Master Bolt (the Helm of Darkness' theft was unknown at the time) in order to prevent a war. Before Percy went on his quest, Luke gave him a pair of winged shoes, which would actually drag him, along with the Master Bolt, down into Tartarus when he neared it during his journey in the Underworld (it was believed that Hades stole the Master Bolt). However, this failed when Percy gave the shoes to Grover, who managed to escape from the burden when the time came.

Defection From Camp Half-Blood
After Percy discovered that the Master Bolt was in a backpack that Ares gave him (when he neared Hades) and won the Helm of Darkness in a duel with Ares (who was unknowingly being influenced by Kronos), Percy returned alive along with his two companions, therefore thwarting Kronos' plan.

In order to prevent Percy from interfering again, he took Percy in the woods for a "friendly chat" and some coke. Percy accepted the offer. While talking with Luke, Percy began to slowly see Luke's dark side, as he threw an empty coke bottle in the river and began to look more bitter in appearance. Luke then summoned a pit scorpion to poison Percy. He told Percy of why he joined Kronos and the plan of gaining the two sacred items for Kronos, leaving by creating a portal using his newly acquired sword Backbiter (which was the newly forged form of Kronos' scythe). However the assassination attempt on Percy failed when the scorpion was killed and the wood nymphs brought him back to camp for healing.

Luke's betrayal was a surprise to many campers and counselors, especially to Annabeth (who had romantic feelings for him), who reacted with great sadness at the loss of her childhood friend. However, Annabeth had seen Luke had been different after his quest, and was forced by her common sense to believe Percy's words.

Poisoning Thalia's Tree
After his defection, Luke took control of a monster cruise ship called the Princess Andromeda, which serves as his base of operations. In order to render Camp Half-Blood defenseless and eliminate a major ally of the Olympians, he poisons Thalia's Tree with the help of a spy in the camp's ranks, planning to later 'allow' Percy and Annabeth to take it and heal Thalia's tree, so Thalia will be purged from it. He also frames Chiron for the poisoning, causing him to be fired from the camp and be replaced by Tantalus.

At first, Clarisse was sent to find the Golden Fleece (and save Grover from the cyclops Polyphemus but was intercepted by Percy Jackson, along with a group of allies consisting of Annabeth Chase and Percy's half-brother Tyson.

Hermes, Luke's father, persuaded Percy, Annabeth, and Tyson to go on this quest, and told them to go onto the Princess Adromeda, hoping that Percy would meet up with Luke and convince him to stop his assault on the gods. Percy and his allies landed aboard the Princess Andromeda, not knowing of it's true nature, and were captured.

During this time, Luke told the two of his plans to use the Golden Fleece to complete Kronos' resurrection and attempts to recruit Percy and Annabeth to his cause (not willing to recruit Tyson as he reminds him of the cyclops that captured him and Thalia years ago). The two refuse, Luke ordering his bodyguards to feed the trio to a drakkon. Percy and the gang escape through a lifeboat propelled by wind canister given to him by Hermes.

Luke later intercepts Percy and his friends when they are looking for a boat that they can use to get back to camp. When he is interrogating Percy for the Fleece in front of a pool (his army of monsters watching), Percy uses the pool to send an Iris message, tricking Luke into revealing the fact that Chiron was framed for the poisoning, resulting in Chiron being rehired (using the fact that he was in a panic due to Percy giving the Fleece to Clarisse). Enraged, he ordered Percy and his friends to be killed. Prcy convinces Luke to duel him, a moment both had been waiting for a long time. Luke effortlessly defeats Percy, but is prevented from killing the latter when he's knocked into the pool by a boxing glove glued to an arrow. The arrow was shot by Chiron and his family of centaurs who had just then arrived and proceeded to save them. When Percy escapes, Luke's spite and hatred for the son of Poseidon only increases.

Thalia is resurrected at long last. It is possible and very likely that Luke's allegiance to Kronos was affected after this. He obviously wanted Thalia to be resurrected, shown when he says to Percy that he was going to give him the Fleece after he was done using it to resurrect Kronos.

Search for the Ophiotaurus
After Thalia's resurrection, Kronos' second in command, Atlas, devised a plan to capture the Ophiotaurus, which would grant the power to destroy Olympus to whomever killed it and burned it's entrails. He remembers the Prophecy and chooses Thalia to be its killer.

Luke Castellan is assigned to aid Atlas with this. However, Thalia and Luke were childhood friends and romantically attracted to each other, bringing Luke hesitation to carry this mission out. Knowing this, Kronos tells Luke that if he doesn't succeed in this mission, he would be chosen to be Kronos' host and therefore suffer a fate worse then death.

Some time before his mission in the Labyrinth, Luke journeyed down to the Underworld to perfect his design as Kronos' host. Making his way to the river known as Styx without being spotted, Luke bathed in the waters, granting him the Curse of Achilles, which made him immune to injury, except in one particular spot.

Luke traveled through the Labyrinth to accomplish this goal. Along the way, he encountered a son of Poseidon who owned a gladiatorial arena in the Labyrinth.

The first time this (Luke bathing in the river Styx) is hinted is in a nightmare of Percy's, where he carries the sky in a plan to trick Annabeth into holding it after she was captured, which of course succeeded. He and Atlas later use this to their advantage by forcing a captive Artemis hold the sky in her place, and Luke is happy that Annabeth survived. He also convinces Atlas to keep Annabeth alive until Winter Solstice. It is a certainty that he bathed in the River Styx before this, as he would not have been able to hold the sky otherwise.

Luke is later seen with Atlas when he summons Skeleton Warriors to hunt down Percy Jackson.

The Fall
His final appearance in The Titan's Curse is when Percy Jackson, Thalia and Zoë Nightshade, a Huntress of Artemis, arrive at the regrowing fortress of the Titans, where Artemis and Annabeth are held captive. Refusing to have to kill Thalia, Luke attempts to sway her into joining their side. Thalia refuses and the two engage in a duel. Their ferocity and power demonstrated is incredible, but Thalia ultimately wins the duel, disarming Luke and cornering him against the edge of a cliff (she claims that she was always able to beat Luke in a duel). Luke continues to goad Thalia, Annabeth begging her to spare the traitor. As Thalia and Annabeth argue over his fate, Luke attempts to use the opportunity to disarm Thalia, but she foresees this and kicks him off the cliff, which causes her much guilt later on.

Although his corpse is seen by both an approaching army of monsters and Percy, it is later revealed that Luke survived the fall. This is because Luke had dived into the River Styx, which made him almost immortal.

After her battle with Luke, Thalia pledges herself to Artemis (though she had previously scorned the offer), in order to stop the prophecy from coming true through her. It is possible she was also thinking of Luke when she made this decision.

Mission in the Labyrinth
Due to his failure to kill the Ophiotaurus, Kronos kept true to his word, assigning Luke as his next host. However, before Kronos would take Luke's body, the latter would aid him in planning an invasion of Camp Half-Blood using the Labyrinth, which had an entrance hidden between two rocks which Percy and Annabeth find while playing a game in Camp Half-Blood.

In order to pass the gladiatorial arena in the Labyrinth he had to assign some of his monsters to fight to the death. When we see him, he has to show the giant one more match. Then a captive Percy arrives along with Annabeth and Rachel Elizabeth Dare. As a result, the owner of the gladiatorial matches has Percy face off against three opponents, the first is easily defeated, Ethan Nakamura, who is defeated with some effort and the giant himself, whom is defeated by Percy. As a result, Luke sends his monsters after them, but they escape with the help of Quintus' hellhound, Mrs. O' Leary.

Kronos' Return
When the time has come, Luke is somehow put into a trance. Two telekhines, along with Ethan Nakamura, perform a ritual to ressurect him. Percy arrives to stop the ritual, but it is too late. When Ethan pledges allegiance to Kronos, the Titan lord rises in Luke's body and is given the reforged weapon, Backbiter, his scythe with which he killed his father. However, Percy is rescued by his comrades, Nico di Angelo sealing their survival by summoning a dome of earth over the fortress where the ritual was performed.

A Hero's Death
For the war the largest part of the war, Luke is completely controlled by Kronos. In this time, Percy learns that when Kronos achieves full power inside of Luke's body, he will burn through Luke's body and attain his true immortal form, which would mean the end of all life.

Kronos made his way to the throne room of the gods with Ethan Nakamura, destroying the city of Mount Olympus as he did so. Meanwhile Percy, Annabeth, Grover, and Thalia follow closely after. Thalia's legs are trapped under falling debris and the others continue on. Kronos battles them in the throne room when they arrive, but Annabeth is able to catch Luke's attention, reawakening him. But only partially.

Ethan Nakamura betrays Kronos and attacks him, unsuccessfully of course, as his sword shattered against Luke's invulnerable body. Several shards lashed back at Ethan and impale him, and he staggered to the ground. Kronos, now having an internal struggle with Luke, opens a hole in the floor beneath Ethan, and he tumbled to his end. Kronos continues to batter the trio, getting closer to his ultimate transformation to his original self.

But Annabeth managed to coax Luke back to his own mind. Luke let Percy knock Backbiter into the hearth, leaving Luke defenseless. A beaten Annabeth gives Percy her knife, as they both realized that Luke was the true victim of the prophecy. Percy gave the knife to Luke who stabbed himself in his Achilles heel (weak spot), his left armpit.

Percy, Annabeth, and Grover looked away as there was an explosion, and Kronos' fading screams. Luke was left lying on the floor, dying. Annabeth says that he would go to Elysium and Luke replies "Think … rebirth. Try for three times. Isles of the Blest", Annabeth replying that he always pushed himself too hard. Then, Luke asks Annabeth if she loved him, and Annabeth replied that she thought she did but she truly thought of him as a brother. Then Luke pleads to Percy to not let this happen again. With that Luke (sadly) died just before the gods arrived after defeating Typhon. In the end he was taken away by the Fates, blessed by Hermes, and remembered and honored as a hero by not only Percy, Annabeth and Grover, but by all.

Luke's Sword
Luke carries the half bronze half mortal steel sword Backbiter. Unlike Percy's sword which can't hurt mortals as they aren't important enough to even bother being killed, Backbiter can hurt both immortals, monsters, and mortals. As it's made from magical bronze and mortal steel. The two metals the sword are made from are opposite, having magic fused with mortal metal. Percy could even sense that the two metals were trying to escape each other during the forging and that someone (probably the forger) died in the creation the sword. Also, by the name "Backbiter" it meant he would back stab his friends in the back.

Personality
Luke started out as a bright, happy young boy. Over time, he slowly realized that his mother 'wasn't all there'. She began to scare him when she had her fits. Her eyes turned green and she kept going on and on about his fate. This later caused him to run away and distain his mother, though he loved her deep down still.

He loved Thalia, but their relationship ended because of her 'death' and transformation into a pine tree. Luke resented the gods for not saving Thalia, and this caused him to resent Olympus.

After his quest failed, Luke began to become sullen and moody, not caring about anyone but himself. He moped around a lot, drowning in self-pity until Kronos spoke to him in his dreams, and convinced him to take down Olympus. Luke's hurt feelings towards his father, and his hatred towards Zeus for not saving Thalia twisted his good nature and turned him into an angry man bent on revenge.

He also used Silena Beauregard horribly, wooing her, and then persuading her to be his spy so that people wouldn't get hurt, and it would be a quick takeover. When she wanted to stop giving him information, he threatened to tell everyone about her betrayal. But he did not keep his false promise, and many demigods (including her later boyfriend Charlie) were killed because of her.

However, there was still good in Luke. He was going to let Percy and Annabeth take the Golden Fleece and heal Thalia, as he still loved her, and continously offered to let Thalia and Annabeth come over to Kronos' side, showing he still loved them both.

In the end, Luke's true, good nature won against Kronos, after Kronos hit Annabeth and tried to kill her. He remembered the promise he had made to her, and stabbed himself, saving Olympus, Thalia, and Annabeth.

And though he was remembered as a hero in the end, Luke was responsible for many young childrens' deaths because of his petty and vengeful actions.
