Fan Casting Luke Castellan in Percy Jackson & The Olympians

Introduced initially as the friendly head counselor of the Hermes cabin, Luke is revealed to serve Kronos at the end of The Lightning Thief. He is resentful of his father, who adhered to the gods' policy of non-interference despite May Castellan's mental illness. He ran away from home at a young age and eventually arrived at camp. After the loss of Thalia, a failed quest and continued silence from Hermes, his ongoing resentment turned into a strong hatred of his father and the other gods. Described as decent and kind before Kronos, he behaved with volatility and violence after his defection.
