AMINE AND MANGA

In the Slayers universe the Lord of Nightmares is the ultimate being, the creator of at least four parallel worlds. The Claire Bible, an artifact containing the knowledge of a fallen shinzoku, Aqualord Ragradia, states that the Lord of Nightmares seeks to regain its "true form", which is only attainable by destroying these worlds and returning them to the chaos that it itself is. For unexplained reasons, though, the Lord of Nightmares has not acted upon this desire by itself so far.

On each of these worlds are gods (shinzoku, lit. "godly race") and demons (mazoku, lit. "monster race"), fighting without end. Should the gods win the war in a world, that world will be at peace. Should the demons win, the world will be destroyed and returned to the Sea of Chaos. In Lina's world, the supreme god is Flare Dragon Ceiphied, and the supreme demon is the Ruby-Eye Shabranigdo. Long ago, their war ended more or less in a stalemate, when Ceiphied was able to split Shabranigdo's existence into seven pieces in order to prevent him from coming back to life, then sealing them within human souls. As the souls are reincarnated, the individual fragments would therefore be worn down until Shabranigdo himself would be destroyed. However, Ceiphied was so exhausted by this that he himself sank into the Sea of Chaos, leaving four parts of himself in the world.
