The Dark Wizard

At the beginning of time, after the fall of the Giga, there were the First Overlords. These included the Batking, the Witch, the Wizard, the Dark Witch, the Dark Wizard, etc. Over time as mankind progressed they died off. One by one they fought and killed each other. Before long there were only two survivers : the Wizard and the Dark Wizard(who was in a coma). After countless years the Wizard, in medieval times, died from unkown causes.
Now the Dark Wizard has awakened from his coma. Leading and army of magicians and wizards and druids etc he once again plans to become the overlord of all. He is currently attacking all he sees to cause havoc. Morgoth is attempting to gain his alligance.
The only person fighting back is a mysterious man who disappears after ever fight. No one knows who he is.
