Percy Jackson and the Olympians: Legends

Luke is described as a tall, college-aged young man with an athletic, muscular build. He had puffed curly black hair, brown eyes, a sharp nose, and the sneaky look like all Hermes demigod children. Many girls found him particularly attractive, even the Empousa Kelli. The only thing unsettling about Luke's appearance was a thick, deep pale scar that ran from the bottom of his eye down to his chin caused by Ladon, the guardian dragon of the Garden of the Hesperides.

Luke was more selfless and moral in after he was killed during the bloodiest battle of the Second Titanomachy and wants to redeem himself in any way he can so he can reach the Isles of the Blest. He's a natural leader with a tactical mind, often devising plans to overcome overwhelming odds. In addition, he's fiercely loyal to his companions, willing to sacrifice himself to save them

After his fateful end at the Battle of Manhattan, Luke Castellan’s spirit found itself in a realm of shadows and echoes known as the Elysian Fields—a place where heroes rest after death. However, Luke's redemption came with a twist: he wasn't destined to rest. The gods, impressed by his final act of bravery and sacrifice, decided to offer him a chance at redemption in another world. In this new realm, Luke was reborn with fragmented memories of his past life. He knew he was once a warrior and a leader, but the specifics were shrouded in mist.
