In the universe of Slayers, the supreme being is neither good nor evil, but is called the Lord of Nightmares, who created everything, and who is said to "shine like gold on the Sea of Chaos." Later, it is revealed that the Lord of Nightmares is in fact the Sea of Chaos itself. Four pillars rise out of the Sea of Chaos, and each supports its own world. Since the Sea of Chaos comprises the Lord of Nightmares' body, the worlds likewise spring from her. In Slayers Next, the Claire Bible confides that if the worlds are destroyed and returned to chaos, the Lord of Nightmares can return to her true form (although why she created the four worlds in the first place has not been revealed, neither by the novels nor the author himself).
