Bahamut's Shame
As the story goes, worshipers of Bahamut and worshipers of Gruumsh spent years warring. As the dead piled up, a Bahamut faithful crafted a weapon of devastating power. Most of the inventor’s peers balked at its use, but some felt it was justified. Those few who used the weapon were twisted into mad, dark beings by its corrupting power. The rest of Bahamut’s flock locked them and the weapon away in a dungeon prison.
The dungeon and its terrible secret were long forgotten—until a group of rakshasas happened across the ancient tale. Now they seek the weapon for their own designs.
