Every prison in the game has a warden. The Warden is a staff member and is in charge of the entire prison. The Warden will be the person that send you an introduction at the start of a game, approves job applications and sends you to solitary if evidence is found linking back to you.

There are currently multiple Wardens in the game and each of them have the master white key that opens the prison's main gate. This key is un-obtainable however as the Warden can not be attacked. The main gate will be unlocked however, if the player knocks out enough guards at once.
