Object class: Euclid
The strangler, or known as scp 000, is a necklace, about half a foot long and wide. There is a heart - shaped emerald about half an inch long and a quarter inch thick.
When worn, the subject feels affection towards the necklace. However, any attempt to touch the necklace will result in the subject being strangled until he or she passes out.
When awake, the subject has strong feelings of aggression. The subject also claims to see a humanoid figure with jagged teeth, sharp claws, and green skin in a hunched position. Making any noise will result in the creature attacking. Subject reports snarling from the creature, as well as it saying the same phrase,” you shouldn’t have done it.”
After a few minutes, the subject is reanimated, but shows no sign of memory or intelligence, attacking anything.
If the necklace is kept on for over an hour, then the necklace will lock, and the subject is unable to remove it.
