Ug-Qualtoth

Ug-Qualtoth is a mentioned supernatural entity in 2277.

Background
Ug-Qualtoth is commonly associated with an obelisk in the virulent underchambers of the Dunwich Building. Attached to the obelisk is a female figure, who reaches outward with one arm. The obelisk itself is described as being a "wicked thing."

In late April 2134, Ug-Qualtoth returned to the Dunwich Building, and was present at the beginning of May.

Books play a vital part in dealing with Ug-Qualtoth. Jaime Palabras' father was carrying an occult tome with him, which was found by his son and ultimately forced him to remain near the obelisk. The Krivbeknih, which has the same origin as the obelisk, can be destroyed by pressing it against the obelisk. Alternatively, Obadiah Blackhall can use it in the basement of his home to let Ug-Qualtoth return.

Appearances
Ug-Qualtoth is mentioned only in Fallout 3. Its associated obelisk appears in the game.
