The being is outside of the Presence's creation. It is the soul of darkness itself, a complete absence of divine light. In every way equal to the power of the Presence, it is his opposite who existed before Creation. After the Crisis on Infinite Earths, a group of mystic madmen of the Brujería cult attempted to conduct a mystic ritual to contact the Great Evil Beast; it went awry and instead the entity awoke as a furious monster, unknowing of its own power and confused about its existence. It encountered a number of mystical heroes, who unwittingly angered the being and directed it against Heaven, leaving the defeated heroes behind. They did this unknowingly, despite their best intentions; Etrigan taught it that darkness was evil, Dr. Fate told him that evil was despicable, and the Spectre taught it the concept of revenge. Infuriated, the being sought to assault Heaven to demand answers from the Presence as to its existence, trampling all that it crossed paths with. This power was so huge, it caused Hell's main three figures - Lucifer, Azazel and Beelzebub - to form a triumvirate in order to defend themselves should the Great Evil Beast decide that it wanted Hell as its realm. A different faction, led by the Demons Three, banded together to follow the Great Evil Beast, whom they saw as the ultimate sin and the ultimate evil. However, before the Great Evil Beast reached the gates of the Silver City of Heaven, it encountered the Swamp Thing, who taught it the concept of good and evil, life and death, intertwined so that one could not survive without the other. The Great Evil Beast then extended its hand, and something happened that nobody had foreseen; the Presence extended His. When both hands shook, they both vanished as the light from a Yin/Yang symbol appeared. The Phantom Stranger later notes that their conflict hadn’t simply gone away, but that it had been altered and they’re both still locked in battle against each other The realm of the Great Evil Beast, an expanse of complete and utter darkness known as the Sunless Sea or the Shadowlands, has been referred to as the power source for shadow-manipulating characters such as the Shade, his archenemy Simon Culp, the Shadow Thief, Nightshade, Ian Karkull, and Alan Scott's son Obsidian. It also known as the source if all magic in the DC Universe
