A well-known demon lord and lesser deity from the Abyss. His title, Prince of Demons, was earned with immense power and influence. However, he is his own worst enemy. His two heads, Amaeul and Hathradiah, are constantly at odds with each other.
AKA the Deep Father/Leemooggoogoon (Lee-moog goo-goon) by the kuo-toa, he manifested from the depths of the Darklake during a ritual from his worshipers. What he's doing in the Underdark is a mystery, but it can't be anything good.
