Wrath of Thunder

Created by mad Dwarf Engineer Sven Hasselfrapp, the Wrath of Thunder is the third lighter-than-air ship of the Thunderbarge class to be launched from Zhufbar. The first went down in flames during the Battle of Black Vale, the second has not returned from a recent good-will journey to Nuln, and the third, the pride of Sven, is the Wrath of Thunder. The ship has served in several battles, mast recently bombing the Knuckle Skrapers tribe of Orcs off the mountainside and into oblivion.
