Item #: SCP-XXX

Object Class: Safe

Special Containment Procedures: SCP-XXX is to be kept in a safe item containment locker at Site-66.

Description: SCP-XXX is a hardbound book, measuring 10cm by 25cm containing exactly 13 pages.

When allowed to open by a human, SCP-XXX causes sudden and intense triskaidekaphobia1. This effect is instantaneous, and manifests first as explicit disgust of SCP-XXX itself.

Afflicted individuals will begin to compulsively notice patterns relating to the number 13. Early affliction is specific to numerals, pictograms, and verbalization of the number 13. After one day, collections of exactly 13 similar items incite distress and anxiety. The 13th minute of the hour displayed on a clock invokes terror.

All afflicted individuals begin to hold an obsessive observation of the number 13. Observances grow increasingly illogical and far fetched, the phobia worsening over several days. Incidental instances and representations of the number 13 in mundane scenarios incite panic. Any verbal acknowledgement of the number 13 is immediately met with violent anguish.

All effects instantly cease exactly 13 days and 13 hours after opening SCP-XXX. Then, after 13 days and 13 hours, the anomaly will refresh, repeating indefinitely.
