Dumagand was a dwarven fortress in Grundia.
Description[]
It was half-way between Baldamand and Flint on the Stonewalk. [1][2]
It was believed that Dumagand could possibly survive a siege of one year, even against an army of ten thousand orcs. However the fortress fell more quickly during the Demonwar, to an army composed of orcs, trolls, and frost giants. [3]
