A One-Round Living Greyhawk Theocracy of the Pale Regional Adventure
From the introduction:
The pounding of hooves quakes the earth beneath your feet. The clash of swords rings in your ears. The stench of rotting flesh hangs over the broken pitch, like torn pennants draped over twisted bodies. Sweat stings your eyes for fear of the coming battle as you look out onto a field rent by carnage and howling bloodlust. If only there was a way out.
