The Town is the uninformed majority, representing usually 3/5ths. Their goal is to kill off all of those who oppose them.
The more people talk and communicate, the better chance the Town has. It is only through silence that a Town will begin to crumble.
The Mafia represent 1/5th of the player base. Although small in numbers, they hold powerful abilities, are able to kill nightly, and start the game knowing each others identities.
The Mafia wants to plant seeds of doubt into the members of the Town to pit them against one another.
The Neutrals are split into 4 sub-alignments. Evils, Supports, Leagues, and Benigns. Neutrals make up the remaining 1/5th of the player base and will consistently have different goals.
A lone wolf that has to play well with others until they are no longer outnumbered.
