Xotli, known also as the Lord of Terror, or the Black Kraken of Atlantis was a demon-god of the Elder Night. Xotli was worshiped first by the Atlanteans prior to the Great Cataclysm, and later by the Antillians during the Hyborian Age.
Xotli was served by a caste of dark wizard-priests known as Hierarch of the Sacred Mysteries of Xotli. The Hierarch ruled the Antillian kingdom from the city of Ptahuacan, where they conducted dark rituals of mass sacrifice to their demon-god to bring him forth into the world.
Xotli appeared unto his Antillian worshippers as a rolling cloud of ebony darkness; a vortex of ultimate, boreal cold. Xotli would consume the living souls of those slain upon his towering, pyramidal altars in the islands of Antillia, while the bodies of the dead were discarded into a deep pit to feed the dragons kept inside the pyramid.
In his later years, Conan the Cimmerian travelled to the Isles of Antillia to fight the followers of Xotli who had been harassing the coasts of Hyboria and unleashing the Red Shadows to steal souls to feed the voracious Xotli. Conan defeated the dark god and liberated the people of Antillia from the priests by using a Phoenix amulet that was given to him by the prophet of Mitra, Epemitreus the Sage. By breaking the amulet, Conan released the power of Mitra's Light, which destroyed the demon-god and saved the lands of Hyboria from the Red Shadows.
