Kyuss

The true story of the being known as the Worm that Walks was a mystery to scholars. The only known fact all agreed on was that the Worm that Walks was originally a demigod called Kyuss, who had lived in the ancient past as a mortal necromancer and created many aberrant undead creatures, such as the spawn of Kyuss that plague regions of the Underdark.
Eventually, Kyuss's wickedness made his contemporaries to exile him to the fringes of society. Rather than languishing as an outcast, he became the prophet of a wicked cult who believed in the dreaded Age of Worms. During this time Kyuss discovered the ruins of a dead civilization in an island near Maztica, known as the Wormcrawl Island by the elves of Evermeet, and claimed the site as its own, where he ruled as a god-king. In the ruins, his followers discovered ancient metal plates, which held terrible secrets but also confirmed every prophecy he had spoken.
Through these inscriptions, Kyuss discovered how to transcend mortality at a terrible price—the lives of his congregation. On one bloody night he instructed his priests to slaughter them all, and after that Kyuss murdered the priests as well. When he was finished, he fused his essence with the foul ruins, gaining and losing his divinity in one moment. He was neither mortal nor god, and he was bound forever to the ruins. However, he was transformed into something far worse.
Kyuss is worshiped as the most powerful of the "old gods" by the Masters of Ceremony.
