A little story (part of Crossover Crisis Lord or smth)

Chapter 1: The origins of the Book of Evil Many millennia ago there lived a great king of the demon realm called Rylos and his wife Cordelina together they made a powerful duo and almost conquered the human realm until they were overthrown and banished by The Brothers Grimm now fueled by spite and hatred Cordelina used all of her demonic energy to harbor her soul inside of a book called The Ascension Prognosticus rumored to be able to grant your hearts greatest desire whatever that may be. eventually the Brothers were once again greeted by Cordelina this time in the form of her book Francois had decided upon the name "Book of her majesty Queen Cordelina of Rylia" off of the fact that the book was empty save for a picture of the beautiful demon queen on the first page, eventually however as the Brothers Grimm left the demon realm they had abandoned the book which was exactly what the queen wished would happen she followed them where ever they went and eventually came upon The Morgue and Morgue City once there she put on a guise to reclaim the cauldron of Orchilos stolen from their royal castle by the Brothers she had succeeded in this task and once again regained her physical form however this time the Brothers couldn't defeat her and so it has come to warriors from across the Omniverse to help save..... well everything I suppose one of those warriors funnily enough is Cordelina's own kin Ryla: princess of the demon realm. she and many others are all that stand between salvation or eternal pain in the Queen's hellfire pits..............
