Dargrath's caverns

Dargrath's caverns was a systems of caves and tunnels located beneath the Earthspur Mountains. As the 14 century DR, they were the last remnant of the once-great hobgoblin realm of Haekrukkha. In fact, the caverns earned their name from Dargrath, the legendary hobgoblin warlord whose name meant "Great Slayer" in the goblin language.
