The Glass Blower was a human man who was transformed into a large, tentacled creature when Whistler's plague ball exploded. He was originally named Rutger but he rejected this name after he was transformed.
He resided in the Ajax Glassworks building, a factory in London that he owned. He used to emply a lot of people but came to be the only one still there.
Nadira sent Angel to the Glass Blower because he might help him figure out what was going on in Magic Town. When Angel found him however, he was far from cooperative and quickly threw him out the window.
