Before the story starts.

Forgotten and Betrayed by all except Grover, Annabeth, Tyson, some of the gods and Chiron. The rest of The Seven, Reyna, Thalia, Nico, the Stolls, and Will are dead. but why the betrayal? Kevin Johnson, Son of Poseidon, Percy's half brother.

All rights go to Rick Riordan except the story and maybe some OCs (I will put an AN if I create any)
