Lore & Background
Luke ran away from home at nine years old and arrived at Camp Half-Blood at age fourteen with Annabeth Chase and Thalia Grace. Following the loss of Thalia, a failed quest, and continued silence from his father Hermes, Luke's resentment turned into strong hatred for the gods. At the end of The Lightning Thief, he was revealed to serve Kronos. He received a sword named "Backbiter" from the Titan Lord. This weapon was later reforged as Kronos' scythe, possessing the ability to harm both mortals and immortals. Luke's descent was fueled by his belief that the gods neglected their children, leading him to orchestrate events against Olympus.
In Their Own Story
Just before giving himself over completely to host the spirit of Kronos, Luke's actions set in motion the conflict that defined the series. He utilized his position as a trusted friend and counselor to manipulate Percy Jackson and others from within Camp Half-Blood. The scar on his face, a permanent mark from the dragon Ladon, served as a physical reminder of his past trials. His swordsmanship was formidable enough to challenge heroes directly. By wielding Backbiter, he became the primary vessel for the Titan King's power, aiming to destroy the current divine order. His betrayal was not immediate but grew over years of perceived abandonment by Hermes.
