You are part of the Prophecy of the Seven. The seven include Nico, Hazel, Piper, Jason, Leo, Percy, Annabeth, Frank, and you. Well you and Nico are part of it but not the seven that were chosen. Just backups. When you and the others were going to find the statue of Athena you fell down into Tartarus. They were trying to find a plan to get you back until Leo jumped in after you. "Ok. You all know the plan," Percy says as he turns around to get you. "Uh dudes. He jumped," Nico says as he watches Leo jump in after you. "HE JUMPED!?" Percy screams when he hears this.
