I think Needleman may be Bellagar as he's just as loony. My theory anyways as he also tells you how to undo Bellagars spells. How would he know that, unless he's one and the same.
You liked Bellagar, thru the whole game I was thinking hope I can kill this guy but it never happened.
Also the people in the mine tower are alive but after you save them the dummy's thank you and then run out into the poison. LOL!
