Thrice The Brinded Cat
Kyuss (pronounced kai-uhs) is a demigod concerned with the creation and mastery of the Undead. Known as the Bonemaster, the Wormgod, and the Herald of the Age of Worms, his symbol is a skull erupting with writhing green worms.
Kyuss’s faithful believe that life is an obscenity, albeit a temporary one, and that Death offers only nothingness. Undeath, then, is the only worthwhile goal, and followers of Kyuss are encouraged to spread this gift as far as they can. They are permitted to control them if necessary, but encouraged to set them free to do as they will when their creators have no further use. Undead are sacred to Kyuss, and his followers are not permitted to destroy them except in self-defense.
Once a human priest of Nerull in the Flan kingdom of Sulm, Kyuss escaped that realm shortly before its destruction by fleeing to the Amedio Jungle, when he gained many followers. Kyuss later went to the Spire of Long Shadows, where he sacrificed all of his followers to achieve hero-deityhood. Prior to this, he had sacrificed artifacts of great power, as well as living souls to Nerull in order to gain his favor.
