First recorded sighting of SCP-4862 moving through the mountains of ███████, Ireland
Item #: SCP-4862
Object Class: Keter
Special Containment Procedures: Currently, there are no active operations to contain SCP-4862. Operatives of MTF Lambda-5 are currently tasked with devising strategies to locate natural manifestations of SCP-4862 and apprehend it before its disappearance, along with monitoring SCP-4862-5, SCP-4862-6, SCP-4862-7, and SCP-4862-8.
Individuals who have come into contact with SCP-4862-A, personnel or otherwise, is to be quarantined to a humanoid containment chamber, with security officers stationed just outside the area or within the immediate proximity with Class-D personnel at all times, in order to prevent a manifestation of SCP-4862. There are currently four incarcerated subjects who show signs of coming into contact with SCP-4862-A, all of which are stationed at Site-17. No anomalous activity from any of the four has been recorded since their incarceration.
Description: SCP-4862 appears to be a castle tower made of black stone brick, with its height at an estimated 250 ft and width at an estimated 50 ft. The top of the tower most resembles a castle turret of medieval origin, with visible crenelations lining the circular edge of the structure. No openings are visible other than an open passageway at the base of the tower, though this has yet to be confirmed. The tower moves through unclear means, propelling itself in straight lines with its base 2-3 ft below ground level at all times. Changes in trajectory are possible if its target moves outside of its initial path. The tower is capable of moving at speeds near 800 mph and covering immeasurable distances in a matter of seconds.
Discovery: The eventual discovery of SCP-4862 began with the broken camera recovered by a policeman in ███████, Ireland. The camera, a Nikon COOLPIX B500 with a cracked lense, was found just on the edge of a deep rut approximately 50 ft in width and over 13 miles in length. Upon further inspection of the SD card, it was determined that the camera belonged to a █████████████, a photographer living in Ireland who disappeared in 20██, █ years after the discovery of his camera. █████████████ will be referred to as SCP-4862-1. The contents of the SD card hold the culminated photography of SCP-4862-1, with the exception of the last five photos, which contain the first recorded photos of SCP-4862. The first two photos show extremely zoomed-in shots of SCP-4862 in distant mountainous areas during the day, the second photo showing the tower closer to the camera than in the first. The last three photos are taken in the manner of a selfie, showing SCP-4862-1 running in the opposite direction of the tower, looking visibly distraught. The tower can be seen to be past the mountainous area and level with SCP-4862-1. Each picture shows the tower considerably closer than before. The last photo shows SCP-4862-1 screaming as the camera is thrown away from him. There is nothing behind him but an enormous black shape. The camera and its contents were reported to the Foundation upon discovery by the field agent stationed in the ███████ Police Precinct. Upon further inspection, the 13-mile rut holds no human remains.
