Death of Percy Jackson

(If you don't know, Khaos is like the god of creating basically everything we know. I wrote another story where they meet. I suggest you read that one first. If not, be confused on who Khaos is, but be ready for sadness in this story.) A battle between demigods and monsters. The battle atop half blood hill. Thalia's tree is weak, the fleece missing. The seven and Nico prepare for defense. They've fought for a while. Khaos crashes the party a little too late, can he save them?
