Thogmau Goresteel

Thogmau Goresteel was a powerful orc warlord who united the orc tribes of Jezero in a bid to wipe out the local elven populace. Using the power of a shard of the Purple Quintus Gem provided by Cedra, Goresteel was able to raise his fallen troops as undead to keep them marching, along with the corpses of the enemies his horde slaughtered.
Leading his army through the ancient elven forest, his forces likely would have destroyed the elves had it not been hit from the rear by the Red Banner mercenaries that the Barrel Boys led to the area. At the same time, the Barrel Boys dropped an earth orb of devastation in the center of the orc horde, killing many of Goresteel's troops with a magically created earthquake. Goresteel himself faced the Barrel Boys in combat alongside his most powerful undead servants, a wight and beholder zombie, but was ultimately defeated by the adventurers. His body and those of his fallen army were left to rot rather than see proper burial.
