Unseen: The goal of the mysterious Unseen faction is to eliminate the members of the Blue Dragon and any neutral players that attempt to eliminate them. At the start of an Unseen game, two players will be assigned to the classes of the Mastermind and the Assassin.
The Mastermind can
convert players and turn them into evil versions of their original class.
The Assassin can kill or bleed other players to eliminate them from the game.
There can only be three members of the Unseen at any one time.

Cult: Like the Unseen, the goal of the evil Cult faction is to eliminate the members of the Blue Dragon and any neutral players that attempt to eliminate them. The Cult will only appear in games that have at least 11 players. At the start of a Cult game, one player will be assigned the class of
Cult Leader and a second player will be a random Cult member. The Cult Leader can brainwash other players to join the Cult, turning them into a new class based on their original class type.
