Luke was born in Westport, Connecticut to Hermes, the god of travelers and thieves, and May Castellan, a clear-sighted mortal. The family lived happily for a year or so. As a baby, his parents took Luke with them to Camp Half-Blood, where May wanted to host the Oracle of Delphi, which had been cursed by Hades for many years. Right before entering the Big House, she gave her squirming baby son to Hermes. Shortly after, a green glow lights up the house's windows and a terrified Hermes hands baby Luke to Chiron in order to try to save May, but it was too late. The Oracle's curse didn't let her become the new host and instead made her foresee her son's tragic future, driving her insane.

When he was nine years old, Luke ran away from his home because of his mother's unstable mental problems. He travelled for years, lonely and miserable. Once in a while, Luke would try befriending a mortal, but they would never understand when he tried telling them the truth about himself, thinking that it was some sort of game, so he had always ended up leaving. At some point, his Celestial Bronze sword had somehow gotten melted in acid by a monster, so he took to using a golf club as a makeshift weapon.

When he was about fourteen, Luke found a daughter of Zeus named Thalia Grace (aged 12) in a dragon's cave outside Charleston, after she had followed Zeus's sacred goat, Amaltheia, there. Being a demigod herself, Thalia was able to understand Luke. The two chose to team up to stay alive, subsequently traveling across the United States, battling monsters (at one point, several automaton statues) and fending for themselves with Thalia "saving his life a dozen times."

Luke sensed a presence in a nearby alley. It was in that alley that the two meet 7-year-old Annabeth Chase, and adopted her as his little sister after realizing she was a demigod who had run away from home. Luke gave Annabeth the dagger Hal had given him, and the trio left Richmond, headed to their safe house on the James River. Luke would later write down this incident in the green leather diary that Halcyon had given him. Luke, Thalia and Annabeth fought for survival and avoided monsters together. They seem to have taken quite a few photos of themselves during this time, as shown in The Lost Hero. They show Luke wearing ragged makeshift leather armor over his t-shirt, enthusiastically pointing to a dark alley, Luke and Annabeth sitting at a campfire and laughing hysterically, and a photo of them together with Thalia.
