Ug-Qualtoth

An altar to Ug-Qualtoth resides in the virulent underchambers of the Dunwich building, in 2277.

Background
Anthropologist allege that swampfolk have a persistent belief in the occult, positing that they pray to an otherwise forgotten deity known by the human tongue as Ug-Qualtoth. A peculiar monolith depicting this deity, can be found in the depths of the Dunwich building, although its purpose is unknown, as well as why it is there in the first place. Although, a couple facts are known: the Dunwich Obelisk and the Krivbeknih share that same origin and only the "Screaming Sound of Uq-Qualtoth" can full unlock the Krivbeknih's eldritch secrets.

Quests

 * The Dark Heart of Blackhall: Destroy the Krivbeknih on this altar instead of giving it to Obadiah.
