Ug-Qualtoth

An altar of Ug-Qualtoth resides in the Virulent Underchambers of the Dunwich Building in 2277.

Background
Anthropologists have speculated the swampfolk have a belief in the occult, and some postulate they pray to a hitherto unknown entity named Ug-Qualtoth.

A strange altar found in the depths of the Dunwich Building may hold the key to discovering more about this previously unknown entity. Unfortunately, because all investigators into grimoire oddities are currently attempting to scrape together a day-to-day existence or are dead, further research may never occur.

Legend states that pressing the fabled Krivbeknih into this eldritch obelisk forces those of impure blood to face a fiery death.

Quests

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

Appearances
An altar of Ug-Qualtoth appears at the Dunwich Building, and also mentioned in the Dunwich Building terminal entries in Fallout 3.
