The Four Horsemen (4人の騎手) are the harbingers of the apocalypse and have come close to being released on many occasions. Many believe that the horsemen are immortal but they have been shown to be only Demi-Gods and can be killed by an upper being. The Four Horsemen are Famine, Pestilence, War, and Death. To this it is unknown whether we will see the outside of memorise or in the minds of others. The Horsemen are contained in the Horsemen Chamber.
