Item #: SCP-4596
Object Class: Keter
Special Containment Procedures:
SCP-4596 is to be guarded by MTF Lambda-5 in a defensive perimeter of 1km, if anyone attempts to enter this area without level 3 clearance, they must be warned not to enter and if they resist, they must be sedated and an amnestic agent administered. If any person enters SCP-4596-1 said person must be captured, detained and an amnestic agent must be administered, and a post-incident psychological examination must take place.
If SCP-4596-2 breaches containment, a high-voltage cattle prod is to be used on the object and it is to be sedated and returned to SCP-4596-1's basement.
Description:
SCP-4596 is the collective name for a house in the rural Midwest region of the USA near the town of [REDACTED] and the assumed resident of that house. SCP-4596-1 is a house presumed to be built around 1930 that, when entered, will cause an a temporal anomaly, where time is reported to slow to about half speed for anyone inside. It is described as oddly peaceful for anyone who survived an incident with SCP-4596-2.
The inside of SCP-4596-1 consists of a corridor leading towards a set of stairs and a trapdoor, a stairway going up and a kitchen. If anyone touches the trapdoor at the end of the corridor, heavy footsteps are heard coming from below, then, if the door is opened by the person, a white humanoid male with a height of around 1.75 meters (SCP-4596-2) is seen running up the stairs and towards the person at normal outside speed while screaming in an unknown language and the person is presumably killed instantly upon contact, as the corpse vanishes. If the trapdoor isn't opened by the person SCP-4596 will open the trapdoor and will move relative to SCP-4596-1's timescale and SCP-4596-2 will cease aggression if the person turns and moves away unless the person does not have true intent to leave, in which case SCP-4596-2 will speed up and kill them.
