Greyhawk
Temple of Hextor in Highport
The temple of Hextor is more of a training facility than a temple. Once a small warehouse, it was stripped of its furnishings and filled to capacity with slaves and prisoners of war, who were then slaughtered to a man. Now the five priests of the Scourge of Battle hold worship services here, as well as training the devout in war. The high priest is Satran, a grim man with gray hair and a lust for war.
