Scps is a disease that only shadows or hybrids can get. It's extremely odd, so knowing everything about it is important.

- Scps stands for sudden common possession syndrome. It's exactly what the name implies

- Scps leaves a shadow extremely vulnerable to being possessed. To the point where demonoid creatures interested in possessing someone usually go for shadows.

- Scps has a lot to do with eyes. When a demon possesses a victim of scps one or two of the victim's eyes change colour.

- The eye which changes colour in case of actual possession must always be covered so the victim of scps remains in control. As soon as it is uncovered the demon has full control.

- there are 4 types of scps: scps-b, scps-d, scps-s and scps-p.

- Scps-b (or sudden common possession syndrome basic) is the most common form of scps. In this form only one eye is linked to the possession. Some physical signs like injuries also show up on the victims body. This form can easily be controlled.

- Scps-d (or sudden common possession syndrome double) is the least common. In this case both eyes get linked to possession. Covering one of the eyes helps but the victim will never be themselves again.

- Scps-s (or sudden possession syndrome shared) is connected to only one eye. In this form of scps the demon possessing the victim and the victim merge into one creature.

- Scps-p (or sudden possession syndrome paranoia) is the most harmless of them all. Sometimes eye colour change is linked to it but it isn't likely. With this version the victim usually just starts seeing and hearing the demon from time to time.

-Scps-p can evolve into scps-b

- Scps can be passed on from one generation to the next

- Shadows by defect can't get Scps

-Shadows with scps often share traits with the demon that possesses them, like fears.
