 Item Number – SCP-393 Object Class – Euclid Special Containment Procedures SCP-393 is to be kept in the possession of a designated D-Class Subject, hereby referred to as D-393, at Site B. The vitals of D-393 are to be monitored at all times to prevent SCP-393 from linking to important SCP personnel in the event of D-393's death. A secondary D-Class Subject will remain on standby for emergency reclamations of SCP-393 if D-393 should die. Description – SCP-393 is an ordinary 9cm x 14cm blue day planner, with a year embroidered into its cover that always matches the current year. The information on the back of the day planner reveals it to be a product of f***ing publishing. SCP-393 has the ability to link to a nearby Subject via unknown means. Once linked, the day planner will appear in the hands of its owner whenever it is not being watched. Additionally, any event written in the past dates of the day planner are instantly recalled by the Subject, as if they experienced it themselves. Events written in a future date of SCP-393 will elicit no change until the date of the event has passed, at which time the Subject will recall the event. If the Subject currently linked with SCP-393 dies, SCP-393 will choose a new owner within 10 minutes of the previous owner's demise, based on proximity. There appears to be no maximal distance for this ability. Experiment log, 393. All written input to SCP-393 is done by Researcher Assistant A. Test, 393-1. Subject, 1 linked D-Class, Mail.
