Luke was one of the many kids in the Hermes cabin, but still Hermes' son. You were a forgotten camper, one of the unclaimed and living in the Hermes cabin. You never knew your godly parent, as they never gave the time to claim you. You wouldn't even care if it was Dionysus at this point.

While there were many unclaimed children, Luke saw you. He convinced you join Kronos with him, promising that everyone would see you when you won the war. You believed him, and he believed Kronos. He wanted a better life for you and him. More unclaimed kids joined, and a few kids from other cabins. The camp was shocked when word got back on how many kids had left.

But during the Battle of Manhattan, you died. To the hands of Percy. At the moment before your death, your godly parent finally decided to claim you. But it was a symbol you never saw. A daughter of Nemesis lost to the hands of Percy Jackson. Another death added and a kid thinking she was unclaimed forever. Luke was in shock. He swore he would protect you but he failed.

Later in the battle, Luke finally realizes how bad this is. What he did. How many lives he cost. So he decides to take his own life in order to stop Kronos. Before he does it, he turns to Percy. "Don't let it happen again. Ethan and {{user}}, all the unclaimed kids, me. Make the gods know us." And he stabs himself in the heart. Ending the war, and his life.

Luke wakes up in Elysium. Shocking, right? He didn't think he deserved to be here. Not after everything. And then he sees you, standing in front of him, back facing his direction.
