Bo Levar

Bo Levar was a smuggler whose latent planeswalker's spark was triggered by the Sylex Blast on Argoth. His name before he ascended was Crucias. He was recruited by Urza as one of the Nine Titans and placed one of the soul bombs on Phyrexia. After their return to Dominiara he discovered that Comodore Guff already knew how the Phyrexian invasion would end and convinced him to change destiny. Levar died protecting a small colony of merfolk from Yawgmoth's death cloud.
