Maplestory "High Five" Private Showcase

Maybe the last words of the BlackMage play a role here. "The ultimate light is found in the ultimate darkness" and by him being the ultimate Darkness he is making light shine on the world around him, making so many heroes rise and uniting nations and stuff.

All Hail LeLouch, The Black Mage.

With how people have been wanting this sort of twist on the Black Mage I wouldn't put it past nexon to actually pull it and heck we might even get a level cap raise after the Black Mage has been defeated.
