Vronos

Vronos with his etherium mask

Vronos, nicknamed the Grey Fencer, was an Elite Inquisitor from Innistrad. 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 Vedalken Ethersworn. 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.

Trivia

• The masked face of Vronos was the default player avatar in the first series of Duels of the Planeswalkers. He was killed off in the trailer of the Magic 2015 version.
