Ruovar the Red Bull

Ruovar, one of Rhuobhe's lieutenants and a companion from before the Battle of Deismaar, was always an elf of fiery temper and brash actions. As the power of Azrai twisted his form towards an unearthly crossing of elf and bull, Ruovar increasingly lost his self-control and staged many frequent raids against nearby human "encroachments." By the time his transformation was complete (as a red-pelted bull with sharp, horn-like ears and a slimmer but muscular form), he was said to be nearly mindless.
Over four centuries ago, Rouvar and Ruobhe parted company, and the former began a decades-long trek across the land, killing anyone or anything that crossed his path, including a few possessors of blood abilities. Ruovar's hunger for power was inestimable, and it is unknown how much additional power Ruovar gained from these kills. The beast was reported missing over seven decades ago near the land now known as the Magian's Domain, and there it only idle speculation as to Ruovar's current whereabouts and status, though none have claimed to be his slayer - at least none who have been taken seriously by the learned amongst the Khinasi.
