Darvag Grozny

Darvag Grozny dwelled in the fallen city of Kiev and was the closest thing to a Cainite Prince in the area during the Dark Ages, even though he refused to claim any such title. Grozny protected his city from the ravages of all other Cainites, not out of loyalty to Kiev, but because he wanted to destroy the city himself. Grozny was originally a seventh generation vampire until an encounter with a feral Nosferatu around the 13th century.

Since the Dark Ages, this vampire offered sacrifices in blood to the "little grandmother" Baba Yaga who wandered around Kiev. And although he's been hacked to pieces in 1240, Grozny managed to survive and plead his services to the Nosferatu Hag once again in the future.
