It Happened too fast. One day it was there the next it wasn't. The Mist was gone. The Humans, or muggles, or mortals, or whatever you call them, rebelled against the thought of anything beyond average. They locked them up. They wiped their memories. They tried to kill them. There is only one safe place for them. It is hidden, with the last of the survivors from the super mutants, to the wizards, to the demigods, to normal people trying help. They will not be hunted to extinction. Do you have what it takes to be a survivor? CAUTION: I LITERALLY SPENT THIS ENTIRE STORY KILLING ALL THE CHARACTERS. I DON'T OWN ANY CHARACTER BUT JESSICA (so far) AND THE PLOT. THE REST GO TO RICK RIORDAN And JK ROWLING

After the war with Gaea, Nico was hoping he would get some rest. Unfortunately, that is not the case. Hades and Hecate have a mission for him, and it will not be easy. Nico will be undercover at a school for Wizards and Witches called Hogwarts, and he has to protect the golden trio. Redo of 7th year at hogwarts. This is my story so some of the things will be altered to how I see fit. I know Umbridge did not teach potions and really shouldn't be here, but I'm going to have her here for my own reasons. Everyone is alive except Voldemort and Cedric(sorry Cedric). There is Solangelo and there is a decent amount. Please make sure to read the first chapter, even if you only read after the line break because that explains what the quest is. Also, Tonks and Remus never got together. Ever. Sorry. Also timelines do not apply and this is my story so I can do what I want. (High fives myself) I DO NOT OWN PERCY JACKSON OR HARRY POTTER THEY ARE OWNED BY RICK RIORDAN AND JK ROWLING.
