Object: SCP 4666
Class: Keter
SCP-4666 is currently believed to be a single, exceptionally long-lived humanoid entity of unknown origin. Survivors of Weissnacht Events typically describe SCP-4666 as a very tall (between 2 m and 2.3 m) elderly male of European descent, with an extremely emaciated appearance. The entity always appears completely naked, even when observed outdoors in freezing weather.
SCP-4666 activity occurs exclusively within a period of 12 consecutive nights every year, from the night of December 21-22 to the night of January 1-2; this period is known as SCP-4666’s “active phase”. During this phase, in what are termed "Weissnacht Events", SCP-4666 will appear at dwellings in one or multiple locations north of 40°N latitude. In all known Weissnacht Events, these dwellings have shared the following characteristics: isolated rural location, home to a family with at least one child under the age of 8, and situated in an area with snow cover lasting throughout the duration of the event.
Nights 1-7: Children will report seeing SCP-4666 in the vicinity of their family's dwelling. The entity will typically be observed watching the dwelling from a distance, such as from across a nearby field or from the edge of a neighboring forest. In some cases, children will report waking up at night to find SCP-4666 watching them sleep through a window.
Nights 8-11: Family members (including the parents) will report sounds of footsteps coming from the roof or the attic. An extremely unpleasant odor will also frequently be noticed inside the dwelling. No cause for these phenomena will be found. As a result, parents will often begin to suspect that their family is being stalked, or even that their dwelling might be "haunted".
Night 12: There are two possible outcomes.
The first, and most common, is that SCP-4666 will kill all members of the family save for one child under the age of 8, whom it will abduct. SCP-4666 will inflict incapacitating injuries to family members while they are sleeping, then herd them into a single room of the dwelling where it will proceed to kill them in view of each other. The method of killing varies with the event, and will typically be preceded by some form of torture, which appears to serve a ritualistic purpose
