Editing Slayers (section)

===Setting===
In the ''Slayers'' universe, the ultimate being is the [[Lord of Nightmares]], the creator of at least four parallel worlds. An artifact known as the Claire Bible contains information about the Lord of Nightmares' task to regain its "true form",<ref>Episode 21 of ''Slayers NEXT''.</ref> which is only attainable by destroying these worlds and returning them to the chaos (sea of darkness) 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. "demon race"), fighting without end. Should the gods win the war in a world, that world will be at peace. Should the monsters win, the world will be destroyed and returned to the Sea of Chaos.

In the world where the ''Slayers'' takes place, [[Flare Dragon Ceifeed]] and the [[Ruby-Eye Shabranigdu]] are, respectively, the supreme god and demon. Long ago, their war ended more or less in a stalemate, when Ceifeed was able to split Shabranigdu's existence into seven pieces in order to prevent him from coming back to life, then seal them within human souls. As the souls are reincarnated, the individual fragments would wear down until Shabranigdu himself would be destroyed. However, Ceifeed was so exhausted by this that he himself sank into the Sea of Chaos, leaving behind four parts of himself in the world. A millennium before the events in ''Slayers'', one of Ruby-Eye's fragments (which was sealed in the body of Lei Magnus, a very powerful sorcerer) revived and began the {{nihongo|Resurrection War|降魔戦争|Kōma-sensō|alternately "War of Demon Conquering"}} against one of the parts of Ceifeed, the Water Dragon King, also known as Aqualord Ragradia. Ultimately, the piece of Shabranigdu won, but Aqualord, using the last remnants of her power, sealed him into a block of magical ice within the Kataart Mountains. Nevertheless, Shabranigdu's lieutenants remained at liberty, sealing a part of the world within a magical barrier, through which only demons could pass.<ref>''Slayers'' novel 7, [[Tokyopop]] translation, pp. 137–138.</ref>

There are four types of magic within the ''Slayers'' universe: Black, White, Shamanistic, and Holy. Black magic spells, such as the famous Dragon Slave, call directly on the powers of the demons and are capable of causing enormous damage. White magic spells are of an obscure origin and are used for healing or protection. Shamanistic magic is focused on manipulation and alteration of the basic elements of the natural world (earth, wind, fire, water and spirit) and contains spells for both offense and convenience, such as Lei Wing, Fireball, or Elemekia Lance. Holy magic uses the power of the gods, but the aforementioned barrier made its usage impossible for anyone inside before the death of the demon Hellmaster Phibrizzo. As a rule, demons can only be harmed by astral shamanistic magic, holy magic, or black magic which draws power from another demon with greater might than the target.

Above all other magic, however, are the immensely destructive spells drawing power from the Lord of Nightmares. The two spells of this class are the Ragna Blade, capable of cutting through any obstacle or being, and the Giga Slave, which can kill any opponent, but which could also destroy the world itself if the spell is miscast. Some have claimed that these terrible spells, drawing their power directly from the Lord of Nightmares, constitute a fifth form of magic: Chaos magic.
