Okay, I now have two theories. Call me wacky if you wish but I think they're plausible.

a) Bahamut = cult leader

b) Bahamut = lyncher, Ifrit = lynchee

It really seemed like in day 1, Bahamut was completely set on getting Ifrit lynched and no one could figure out why. According to the roles flash (and if the mods followed it for this), lyncher wins if he survives in small games, and he tries to get the lynchee killed, which would explain why he was so intent on getting Ifrit lynched.
