 Item Number – SCP-526 Object Class – Euclid Special Containment Procedures – Armed Containment Area 31 has been established in a 15 km radius around SCP-526-1, which has been officially designated as a military weapon testing site and proving ground, with a no-fly zone in effect. A company-sized element is stationed at Station 526-Alpha to observe and contain the appearance of anomalous subjects from SCP-526-1, and is authorized to use deadly force and self-defense, or in order to contain SCP-526. Approximately 30 minutes before dawn, all containment teams must be at full alert and must remain on alert until sunset, or such time that all instances of SCP-526-2 have been terminated or otherwise rendered harmless. In case of overwhelming hostile contact, additional reinforcements may be requested by ACA 31 Command from Mobile Task Force Sigma-9, Valkyries, including artillery strikes, and close air support if necessary. Description – SCP-526-1 is a hill in Northern Norway. SCP-526-1 is easily identified by a ring of 9 stones, approximately 2 meters in height, with numerous runes inscribed on their inward surface, and placed in a 10 meter radius centered on the top of the hill. Every day at sunrise, give or take 15 minutes, a group of individuals will appear on SCP-526-1, limited SCP-526-2, fully armed, and combat ready. These individuals usually appear to be temporally displaced, but all individuals within a single instance of SCP-526-2 will be from the same time period, and appear to in fact be from the same military unit. Instances of SCP-526-2 have numbered from 10 to 300, and have varied from primitive humans armed only with stone weapons, to modern special forces units, with sophisticated equipment. SCP-526-2 will typically fortify themselves on or around SCP-526-1, and in 92% of instances will simply remain stationary until sunset. In the remaining instances, SCP-526-2 will move away from SCP-526-1 and attempt to attack any individuals they encounter. Even when SCP-526-2 is stationary, however, SCP-526-2 will attack anyone attempting to approach SCP-526-1. Armed containment teams are stationed on site to observe SCP-526-1, and engage SCP-526-2 in case of aggression. Shortly after sunset, all instances of SCP-526-2 will disappear, whether alive or dead. SCP-526 came to the Foundation's attention on 19- after three individuals were hospitalized, after being attacked by quote, a bunch of vikings with axes, end quote. Class A amnestics were administered to the witnesses, and additional reports have been attributed to delusional intoxication. Addendum 526-1, Notable Incident Log for SCP-526. Date, 1991.
