At last, the orc nation of Belkzen is on the offensive! As their ally Ardax gathers his army, the PCs scout ahead to clear the way and infiltrate Wyvernsting, capital of orc traitors. To sneak into the city, they must liberate the Drowning Sands orcs and borrow boats able to cross a quicksand sea. Once inside Wyvernsting, the PCs must sabotage the defenses, motivate rebellious factions to rise up against their enemies, and finally join Ardax's forces in besieging the city. Yet when the dust clears, the PCs identify the root of the undead uprising that's ravaged the land: a haunted divinity that dwells high in Belkzen's mountains.
