Orcs are the scourge of civilization, the raiders who come in the night, slaughtering innocents for treasure and the simple joy of the kill. Their brutality extends even to their own kind, with tribes battling for supremacy and only the strongest individuals surviving to adulthood. Yet despite their fearsome image, orcs maintain a society of their own, having carved out the legendary Hold of Belkzen. Within this chaotic region, warlords vie for supremacy, adventurers plunder ruins long lost to orc barbarism, and those bold orcs who imagine a better life struggle for change. Whether your players are treasure hunters stealing the riches of the past, soldiers seeking to end the orc threat once and for all, or orcs seeking to escape or rule their brethren, this Pathfinder sourcebook has everything you need to run a campaign in the war-torn Hold of Belkzen.
