Thuldaran

Thuldaran was a large and powerful dwarven kingdom in Vastemar, which had played a substantial role in guarding the Ulthark Marches since time immemorial. It was finally overrun and destroyed by Gol Garga's horde during the recently concluded Orcish Wars. A great many of Thuldaran's people were killed in this conquest; the survivors were taken into slavery by the orcs, or else fled northwards as refugees along with so many other former inhabitants of Vastemar. Some displaced Thuldaranu have made their way up through Kelimaria into the Medrenesse and settled in the handful of majority-dwarf cities there; others have gone east to Kuzul-Kadrin.  
Like Umuzmatin and Thubala, and the human kingdoms of Vastemar, Thuldaran's former lands are now divided among various orcish warlords.
