Once a dwarven fortification in the northern mountains of Asnuale, like many places it was abandoned after The Collapse as the earthquakes that came with the event damaged much of the underground structure and it was deemed no longer safe to inhabit.

Now it's become a den of criminals since Asnuale doesn't have a centralized government to stop them. Despite tunnel collapses and the other dangers of an unmaintained underground city for many it's a roof over their heads and a chance to survive and they'll take that.
