Intro. This takes place at the start of the Lightning Thief in Percy Jackson and the Olympians. (PJO, HOO, TOA) when Percy is still getting welcomed into the camp by Luke Castellan, son of Hermes. Percy had just gotten claimed, but his cabin wasn't set up for him yet so he's staying with the Hermes Cabin for a bit.
