The Power Puff Guild
Saruun Khel was the center of a great minotaur empire until approximately 300 years ago. It then mysteriously collapsed. After years of monsters infesting the ruins and occasionally emerging to attack surface dwellers, the Mages of Saruun established the Seven Pillared Hall and ceased the attacks, as well as created a viable trading post with the inhabitants of the Underdark. Outside of the hall, the ruins of the city compose the mysterious, wonderful, and terrible Labyrinth, a maze of minotaur ruins, natural caverns, and more recent settlements eked out by creatures wishing to make a living in the ruins.
