Queen's Man is a member of the Toronto Council who appears in the Judgement arc. He serve's a spirit of patriotism to his native country and lacks much presence and power. His claims his responsibilities lie more with gathering knowledge so others might deal with Others.
He's not described very well.
Not much about his has been shown besides his loyalty to his country and loathing of Demons.
He arrived with the other members of the Toronto Council, having become the new Lord, at the beckoning of Rose and Faysal, with Rose condemning Jacob's Bell to Toronto and dragging them into the conflict.
