Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: In its inactive state, SCP-XXXX is to be kept in a 0.75 meter by 0.75 meter by 0.75 meter steel safe, secured by combination lock and only to be removed from its containment by personnel ranking at Level-3 or higher. Personnel ranking Level-2 or lower wishing to remove SCP-XXXX must seek the approval of Dr. Evagria, to whom the object is currently linked. Aforementioned personnel must be overseen at all times while interacting with SCP-XXXX, and it must be securely returned to containment afterwards.
In its active state, SCP-XXXX will remain in the same safe, though must be removed once daily by the subject with whom it is currently linked, for use until the period of activity ends. Subject must be overseen by at least one Level-3 personnel. If this schedule is not adhered to, both SCP-XXXX and the subject to whom it is linked must both be contained under video surveillance in anticipation of any anomalous event.
Description: SCP-XXXX is, during its inactive state, a regular Advent calendar of varying brand. Currently it is taking the form of ████ brand calendar, expiration date 02/07/20██. SCP-XXXX's inactive state is recognized as when all panels on the calendar are unopened. When in this state, SCP-XXXX is displays no anomalous effects, though personnel entrusted with it during this state claim to feel a greater compulsion than usual to open a panel.
SCP-XXXX enters its active state as soon as the first panel is opened. Upon opening, instead of a chocolate as would be expected, the calendar contains a small screen with a cheery, grinning face, resembling that of Santa Claus, from herein referred to as SCP-XXXX-1. SCP-XXXX-1 will greet the person who opened the panel, apparently considering itself linked with them. Despite this, no speaker or other output device is detectable on or within SCP-XXXX. SCP-XXXX-1 will not acknowledge the presence of anything beyond the opener of the panel. Regardless of the apparent brand of SCP-XXXX's current incarnation, the screens will always be identical behind each panel.
Following the greeting of SCP-XXXX-1, an unpredictable event, apparently completely random, will occur, with the opener of the panel the subject of the event. There is seemingly no limit to the nature of these events, ranging from being incredibly beneficial to the recipient to resulting in their death, and in one reported case the deaths of a number of others (see Incident XXXX-A). One panel must be opened daily until all are open, with failure to adhere to this resulting in the linked person entering a catatonic state, followed by eventual death. Upon completion of the calendar, failure to adhere, or expiration of the linked person, SCP-XXXX will revert to its inactive state, assuming the form of a new Advent calendar of a different brand.
SCP-XXXX was recovered following complaints made to the customer service division of ███████ Corporation, reporting of a "creepy" fake calendar. An audio recording suggests that the child in possession of SCP-XXXX opened a second panel during the call, being discovered in a catatonic state during the conversation. Police were alerted, and news eventually reached the Foundation, who secured the object in its inactive state. While returning the item to the Foundation, two panels were opened by Agent ███████, who soon entered a catatonic state and is recorded to have died during the flight. SCP-XXXX was not tampered with further and was once again in its inactive state on arrival in Site-19.
