The Masked Mage

[Gugnir]

I think the masked mage is following final fantasy III's story line. Or something similar-ish

"Final Fantasy III has eight Crystals. Xande is trying to drain the Crystals of their power in order to create an imbalance between light and darkness. He manages to drain the Crystals on the ground continent, covering it in darkness and freezing time. He is, however, unable to drain the ones on the floating continent. Eventually, the forces of darkness manage to drain the other two Crystals, creating an imbalance that summons the Cloud of Darkness"
