Tales from Elrond
Large City * Population 40,432 (71% Duegar, 29% Assorted Slave Races)
Located in the Underdark to the east of Thunderspire Mountain (twenty-three miles from the Seven-Pillared Hall), the Grimmerzhul Mines are part of the duegar kingdom of Grimmerzhul, named after the current ruling duegar clan. The duegar use a large amount of slave labor to mine the earth for its riches, and most of these slaves are provided by duegar raiding parties or bought from slavers who plague the underdark or the surface looking for victims to abduct. A seemingly impregnatable fortress stronghold called the “Horned Hold” serves as the mining base of operations and it is located to the east of the Seven-Pillared Hall. Grimmerzhul can only be accessed by traveling underdark passages or by magical means.
