Ofotore

In ancient Orcish mythology, Ofotore is a vast unseen underground empire said to exist in caverns deep below Orceron's surface. A common legend was that unlucky travelers could find themselves falling to Ofotore through a fissure in the ground and get lost forever, or ending up tortured by Foijonin, "the Poisonous King of Ofotore."

Obviously, no such place actually existed.
