The Stonemarch

A rugged land of stony hills and deep gorges cut by white-rushing rivers, the Stonemarch is home to tribes of dangerous humanoids and giants. Orcs, ogres, giants, and trolls haunt the farther reaches of these barren lands. Every century or so, Gruumsh's insatiable thirst for bloodshed and conquest calls the orcs of the Stonemarch from their deep holes and whips them into a frenzied mob. They swarm over the Cairngorm Peaks and into the Nentir Vale by the thousands, turning everything in their path to ash and ruin. The last assault came ninety years ago, and the ravaged earth has not yet fully healed. The people of the vale, ill prepared for another rampage, are desperate for new heroes to halt the impending invasion.
-The Axe Bite Pass: A mountain pass that separates the vale proper from the orc infested area of the Stonemarch. (DR396, p.42)
-The Fanged Jaws of Kulkoszar: A great orc-warren that lies in the northern part of the wasteland. Legend says that the first great chieftain of Clan Bloodspear singlehandedly slew the elder iron dragon Kulkoszar. The self-proclaimed King Bloodspear declared the dragon's lair to be the seat of his new empire, and he forged a throne there from the dragon's jaws. Over the years, Clan Bloodspear has extended the original cavern into an extensive warren furnished with forges, arenas, and slave pens. The current chieftain of Clan Bloodspear is Msuga, the Orc Queen, who rules over hundreds of the fierce warriors.
