The evil sorcerer with pointy teeth looked a lot like some of the anti-semitic imagery I've seen. For all I know, the sorcerer might represent Saddam Hussein, a much disliked school teacher, or the Persian version of the bogeyman--"lulu-khorkhore," according to Wikipedia. If Wikipedia is correct, then the pointy teeth fit the bogeyman interpretation. Evil sorcerers often turn out to be that which children fear the most. That said, negative Jewish archetypes often serve as bogeyman in anti-semitic cultures or cultures under anti-semitic regimes.
If the game takes place around the time of Nebuchadnezzar II, then the sorcerer probably is Chaldean--but so was Nebuchadnezzar II, and presumably, the "Babylonian Twins" as well. The king's advisor might also have been the children's teacher, in which case we find support for the sorcerer representing an authoritarian figure from the authors' childhoods.
