He is both the best wizard in the world and the worst devil in history. Although sealed away after his defeat by the Ivory Tower wizards, he escaped. Using Hellbound Island, he connected to and successfully possessed a mysterious power that even the gods were not aware of. Nobody knows what he thinks or what he wants.

I don’t play Lineage II so I unfortunately don’t know the character well enough to give you more information other than the one I found in their wiki page. Pretty amazing details though! It reminds me of Serreniethy’s cosplay last January 2013! Thanks again to Shuichi for sending this in!
