I figured something was up with D'If. His name is from the Chateau D'If which is the prison from the Count of Monte Cristo. The Count was disguised after escaping from D'If, so I thought it might be something along those lines. Didn't figure out that he was Biblioden though. After reading this thread, I wonder if there might be a tie to Alcatraz the First (maybe the brother he killed?)... He would need some kind of talent to be able to still be alive... He also references fighting Alcatraz's "great-great-whatever-grandfather". I don't have the reference, but isn't that how Alcatraz refered to Alcatraz the First?
