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.

The realms lasted until the Year of the Black Unicorn. The realm fell to the phaerimms and other dangers. The surface settlements such as Citadel Adbar, Citadel Felbarr, Mithral Hall, and Sundabar survive the fall, but the underground settlements do not.
