A legendary race of monster-titans that enslaved the monster races in a subterranean underworld called the Underdeep.
They reputedly had high culture, and created all manner of underground cities, gilded statues, and devious traps.
The Gorgoth have not been seen in modern times, though some claim to have seen them in the exploration (illegal) of the Underdeep. Tapestries depict them as far larger than any of the modern monster races.
