Rakunth

The Prime power of destruction is the Black Worm Rakunth; a prime power of chaos and negative energy. It was Rakunth who destroyed the first great globe of Earth, and scattered the remains through the void. After he destroyed Roknar’s creation, the Worm spawned Aroth, the dark lord, which eventually became his bane. It was Aroth who imprisoned Rakunth in a great sphere in the lowest parts of the underdark. With the prime power of destruction out of the way, the creation of light, life and time could begin.

Rakunth is not completely helpless from its prison, he bended gods, titans and dragons to its will. The Worm is a force without compassion; it corrupts the weak of mind into madness and rage to fulfill its needs. And the Black Worm only wants one thing: to end all of existence.

The arch nemesis of Rakunth is the White Whyrm, Io
