Iranian Zār—Fey—ruled part of Persia called Anshan. Since the Throne and the Scepter rule by siphoning all Fey magic away at birth, the Zār chose to refill their wells with music, making such amazing sounds that humans died dancing to it while the Zār absorbed all the energy and emotion from the whole experience.
Unfortunately, people of the Darkness dine on Fey, and conflict grew until the Zār created an ultimate weapon to protect themselves… and then something went wrong.
The Zār are gone. The country of Anshan died, and a mountain made of shadow settled on the land over the capitol city, devouring everything, until there was absolutely nothing left.
