The Great Black Wizard has now his official thread!
It's a mysterious and evil guy and the only thing we know is that he created Draego-Man! (source: bio of Draego Man).
He has 2 indistinct appearances in the 3rd new mini comic. The GBW seems to be awesome IMHO.
Some assumptions:
He could be one of the evil mystics from the Dunes of Doom (Bcrduke)
He could be "the unnamed one".
Similar to the Chaos Sorcerer from Heroquest:
What are your opinion, assumptions and ideas about him?
