Item #: SCP-1856
Object Class: Euclid
Laconic Containment Procedures: Make sure the people working on-site don't spend too long at the site. They should get medical checkups before returning. People should keep repairing the building it's in.
Laconic Description: SCP-1856 is a dead woman who doesn't decompose. Her body is missing its hands, feet, and tongue, and has fake teeth and fake eyes. The body causes everything around it to decay, so the building it was discovered in is falling apart, and people assigned to it suffer from brain-related diseases over time.
Additional Context: It was found with a note written by the woman to someone else. The note implies she was aware of her corrosive effect and chose to seal herself away from the world so as to stop killing people.
