Vronos originally worked as an Elite Inquisitor. When he was attacked by a pack of young werewolves his planeswalker's spark ignited and he ended up wounded on Alara where he was studied by the VedalkenEthersworn. Vronos demanded a high price in return: knowledge. He uncovered some of the lore within the sacred Texts, learned the basic nature of a strange metal and its long-lost creator, and practiced the arcane arts of the metal-working wizards. He repaired his ravaged face with an etherium infix and crafted a filigreed mask of the same material.
After many months of study and travel, he returned to Innistrad as a penitent. He was then charged by Avacyn to find the cursed Garruk Wildspeaker so that she could heal him. He failed and was killed by Garruk instead.[1]
