Kyuss

Kyuss was an extremely powerful tabaxi who went on to become an obscure deity of the Chultan Peninsula.

History
Kyuss was a charismatic prophet in Mezro who led his cult out of that city in -653 DR after persecution from the mainstream followers of Ubtao. Kyuss and his followers founded the religious city of Kuluth-Mar in the Chultengar. His cultists discovered ancient metal plates that foretold the future and confirmed every prophecy that Kyuss had ever made. Kyuss was personally visited by his god, Jergal, who gave him a gift of a single green worm and tutored the man in the ways of necromancy

While his cultists grew ever more devoted by the apparent truth of his visions, Kyuss tried to fulfil the greatest of his prophecies. He sacrificed powerful magic items and built a massive citadel, the Spire of Long Shadows. At the top of the Spire, he created a monolith, through which he channelled the terror, adulation and souls of his entire cult and achieved apotheosis.

However, an alliance of couatls, eladrin and wild dwarves trapped him in the monolith, which prevented him from ascending to true godhood and relegated him to a historical footnote.

Two millennia later, a coalition of banites, Bhaalites and Myrkulites known as the Ebon Triad who sought to resurrect their dead gods, initiated a plan to free Kyuss and use his divine spark to achieve their objectives.
