Delzoun

Delzoun was the great Northkingdom of the Dwarves. Founded in -3900 DR

The name survives as a middle name among modern day dwarves, one of much prestige.

In -100 DR, Delzoun fell to the phaerimms and other dangers. The surface settlements survive the fall, such as Citadel Adbar, Citadel Felbarr, Mithral Hall, and Sundabar, but the underground settlements do not.
