Gloom

Gloom, the Occultist, considers Belladona to be an enemy, having once challenged her to battle. He managed to stand his ground, and their fight ended as a draw, but the effort was so taxing that it reduced him to a incorporeal entity, capable of great magic but no longer able to exist normally on the Prime Material Plane. Thus he now lurks in the Keep of Belladona, invisible to the Countess, plotting revenge.
