Гел Камгоут

Flamberge's Keykeeper. He has sharp blue eyes and long side-swept brown hair. He and Flam do not share a very warmhearted relationship, and will often use the phrase "Keep your mouth shut, you piece of junk" in response to Flam's endless accusations of being a pervert, making it almost something of a catchphrase for him. Rather than reading the Phantom Books he retrieves from the Long-Lost Library, he places them in the Staff of Surtr that he carries, and uses the book as fuel for the fire the staff produces, burning any Phantom Books he comes across along with the memories the current owner had in relation to them. Thus, because of this, he refers himself as a "Libricide Officer".

He is often seen as a very serious and highly observant character, and appears to have highly advanced deduction and cognitive abilities. (From Wikipedia)
