Balrog Halls on the official server is the ultimate evolution of the underground fortress concept. It is completely underground, and the only point of access is through one long, rambling tunnel that's part of a Fikou web of mineshafts. The only way to attack it is to capture another fortress connected by shafts, find the right path, and then storm that fortress.
