Dhakaan was an ancient goblinoid empire that dominated the continent of Khorvaire, until the coming of the extraplanar Daelkyr 16,000 years ago. The Dhakaani goblinoids could not stand against the might and madness of the alien invasion. By the time the Gatekeeper druids bound the Daelkyr and their servants in the depths of Khyber, the empire was a shadow of its former glory. Over the course of millennia it collapsed into savagery, and by the time humanity arrived on Khorvaire, all that was left of the empire was ruins and several clans trying to preserve the remains of the ancient lore and dreaming about the reestablishment of the Empire.
Recently some of the Dhakaani clans have begun to vie for control of Darguun with another goblinoid clan that currently holds control of that territory, the Ghaal’dar clan, which have wrestled the territory of Darguun from Cyre during the Last War.
