Mafia Illuminati, aka Mafia Mason
Mafia
If there are 2 Illuminati, there will be 0 or 1 Mafia Illuminati.
A Mafia Illuminati functions as a normal Illuminati with the exception that he is also a member of the Mafia. A Mafia Illuminati may NEVER reveal their dual role to anyone. He wins if either the Mafia or the Illuminati win. He loses if the Town wins.
