Sasha Dejanstahl Voban

Sasha Dejanstahl Voban is a Campione. He is very cold man who cares nothing for others, only desiring to battle worthy opponents (such as Heretic Gods) and gaining more Authorities. He is willing to kill anyone who gets in his way. Little is known about Voban's past, except that he killed a Heretic God as a young man, becoming a Campione, and is over three centuries old. Voban is not even his real name but a name he picked up for whatever reason soon after he became Campione three centuries ago.
