Nine Legion Masks

The Nine Legion Masks are the Earth-Land's deadliest forms of Holder Magic and Lost Magic ever to have existed in history. Back when Zeref was in control of the world, he had created different forms of black magic from different occasions, often using live sacrifices in order to create them. He would sent out his minions to find worthy sacrifices in order to complete his magics. He found Nine champions from neighboring tribes and decided to make them his new sacrifices. From their sacrifice, nine masks were forged and given terrible powers.
