Roi Noire, your general average person. He has few friends, nothing interesting in his life and no one else to care for.
Though, everything changes when a fiery woman from Hell (quite literally) decides to force him into her servitude, but that's just the beginning of his problems. As it turns out, he's carrying something that entire Realms would kill. Because, everything he thought he knew will be turned upside down, especially after he awakens as one of the most powerful Demons in existence, a Nightmare.
Tossed into an unfriendly Realm, sealed by a Phoenix and carrying the burden of all Realms in the form of the Retained of Chaos.
Roi Noire recently turned Nightmare is thrust into a dangerous position, one that threatens to erase Excelsion on the first wrong move. With him in the center of the action, it is going to be his greatest challenge yet.
(It is recommended to read the previous Book 0 : Prologue.)
