Mendo

Mendo, the Shadowweaver, was a very powerful wizard. He saved Fireball from a demon invasion in ages past. However, this has almost been forgotten as he is now most known for his dark magics and demon summoning, as he was corrupted during the battle, and lured into the shadows afterwards by the gronogar Vralgporus.

He gave advise and teachings to Sargeas in a short period.
