The Prophecy of The Hidden Warriors (bnha x httyd)

This is basically an au of my book The legend of the day glows, (which I really need to update Btw), i do recommend reading the information on the dragons that are in that book as i am going to use those dragons in this book. Also I am not going to really follow the bnha timeline as that won't work for this book, so Sir Nighteye will be alive and was in a coma for a while, and All for One is able to escape Tartarus and they will have to fight him again.
I am also mixing in the nightwings abilities from wings of fire by Tui T Sutherland
