Buttbringg is a legendary Nordic deity who is the patron of butts. He crafts the buttocks of all species in his workshop, an iron spire that reaches up to the stars. Buttbringg carefully forages for materials in the G-urth's depths. He loves creating a great variety of buttocks, from nega to giga, and comments that if any species discriminates against another for their butt quality, they are in the Absolutely Scientific Wrong.

Despite his alignment with Lawful Good, the origin of his materials has led people to believe that their butts are satanic in nature.
