The Slaughter is one of the Entities. It is the fear of pure, unpredictable, unmotivated violence, with strong ties to war. It is the fear of not knowing where, how or when pain will come but that it will, and can be violent like a frenzied killer or calm, cold and regimented like soldiers firing on the battlefield.

Other Appearances Edit
- MAG 117: Testament (Partially; Melanie King's statement)
- Alfred Grifter: A musician whose music drives all who hear it, whether in person or on recording, into a murderous frenzy. Appears alone or in a band, but regardless any performance he takes part of is known as Grifter's Bone.
- Amritsar Ghosts: The phantoms of British troops that massacred almost a thousand unarmed civilians in Amritsar, India. They manifest as a singular fused being, an angry mass of flesh and guns.
- The Deserter: An Italian deserter who had gone gotten and fled into the mountains of Appennino Centrale. He picked off the men sent to kill him with sniper fire until they tracked him to a cave filled with the dead of ancient wars, which opened their eyes and began to sing. He was killed on the spot by a firing squad when his final pursuer cornered him, though no such group was in the cave with him. He may also have been marked by The Corruption.
- Melanie King: Host of the Ghost Hunt UK YouTube channel and employee of The Magnus Institute, who was shot by the Amritsar ghosts and infected by the bullet left lodged in her leg.
- The Piper: An aspect of the Slaughter that appears during wartime. It appears as a heavily scarred, three-faced man with many hands holding weapons, playing musical instruments, or saluting. It plays its pipes before a battle and only those fated to die in the upcoming attack can hear its tune. Rarely some who hear its music will survive to spread the word of Slaughter, but will die when the larger conflict ends.
- An unnamed Avatar of the Slaughter that interrupted The Stranger's ritual in 1787 by killing the main dancer with a cannon. Its interruption of the ritual was also supported by a group of faceless soldiers.
- A maimed figure whose whispers instil a permanent inclination for violence in others.
- A knife that drives the holder to kill anyone in sight before turning it upon themselves.
- A train car from the 11th US Army Hospital train, which perpetually smells of blood. Opening the car reveals a pool of blood covering the floor of the car and a body bag, as well as the hostile spirit of a WWII medic driven mad by Slaughter.
- An old paperback book capable of driving an entire village to slaughter each other by any means necessary.
- Cambridge Military Hospital: A military hospital in use since 1879 and closed in the late 1990's. Though marked by the Slaughter it was fairly subdued, rousing only against intrusion by avatars of other Powers. It was eventually demolished without incident.
- The Trench: An expansive, ever changing battlefield in the ruined world, an endless and meaningless war raging within it. People trapped within it continue to fight, with no idea who they are fighting or who or what they are fighting for.
The Slaughter's Ritual is The Risen War, and was last attempted during World War 2. It involved the playing of instruments on the Nemesis, an English ship sunk during the Opium War, while prisoners from the Japanese North Point POW camp killed each other, and disciples of the Slaughter watched garbed in uniforms from bloody battles. It ultimately failed, Gertrude Robinson speculating that the Nemesis was meant to be bombed in order to complete it, and notes that had they known about Nagasaki a few years later, the ritual may have been successfully completed. 
Connections to other Entities Edit
- The Slaughter stopped The Stranger's Unknowing in 1787 . These two entities also share an affinity for music.
- Between seasons 3 and 4, Melanie protected the Magnus Institute using Slaughter-related abilities, though Melanie may not have been controlled by The Slaughter .
