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.


In his divine form, Kyuss appears as a towering humanoid shaped entirely of green Kyuss worms, with two blazing eyes peering from beneath the hood of his ragged cloak. According to the Kyuss sidebar in Dragon #336’s “Ecology of the Spawn of Kyuss”, his original divine form was a gaunt man with empty eyesockets filled with writhing worms and hands of bare bone, but he has evolved into his appearance of a gargantuan Worms That Walk as his cult grew stronger.


Though Kyuss revered Incabulos as a mortal, his current relationship with the Reaper is unknown.


For over 1,500 years, Kyuss has been imprisoned within an obelisk in a crevice bandit kingdoms, part of the Great Rift Canyon called Wormcrawl Fissure, in a chamber known as the Writhing Sanctum.


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.


The holiest text of Kyuss’s faith is a set of metal plates foretelling a coming Age of Worms, which Kyuss unearthed from spell weaver ruins in the Amedio Jungle.


Kyuss is worshipped by humans, undead, avolakia, and ulgurstasta. The Ebon Triad is a false cult created by worshippers of Kyuss.
According to the sidebar on Kyuss in Dragon #336’s “Ecology of the Spawn of Kyuss”, the most important prayer to Kyuss offered by his cultists is a personal act performed once each month, in which they ingest living worms as a sign of their faith.


Clerics of Kyuss raid graveyards to create undead, selling their creations or letting them run wild. The more powerful ones seek to create new kinds of undead, and seek lichdom or some other form of undeath for themselves. They seek to free their master, and travel to various places holy to their faith such as the Wormcrawl Fissure, the Necropolis of Unaagh, or the ruins of Kuluth-Mar.

According to the sidebar on Kyuss in Dragon #336’s “Ecology of the Spawn of Kyuss”, Kyuss’s clerics are initiated in a deadly rite called “First Ingestion”, in which they drink a Potion of Inflict Light Wounds containing a preserved Kyuss Worm.


Once a human priest of Incabulos 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 Incabulos in order to gain his favor. When he finally did ascend, there was a small problem with his transformation: he became trapped in the same obelisk with which he channeled his power. It is speculated that Incabulos, not wanting to be challenged, even slightly, flawed the ritual somewhat, thus leading to Kyuss’s imprisonment.

Even during his imprisonment, he gained following from some very powerful followers. Dragotha, a wyrm red dragon, was allowed by Kyuss to attain the form of a dracolich. Following this, Dragotha was bound to serve Kyuss, and in the process became his herald. Another draconic follower of Kyuss is Lashonna, a vampiric silver dragon.

Kyuss is responsible for the creation of the spawn of Kyuss, also known as sons of Kyuss, though these are said to be the least powerful of his creations. He is also believed to be responsible for the creation of the avolakia, eviscerator beetle, ulgurstasta, Kyuss knight, overworm, earthcancer centipede, hound of Kyuss, sword of Kyuss, wormcaller, worm naga, wormswarm, and the worm that walks. Collectively, his creations are known as wormspawn.
