Item #: SCP-1918
Object Class: Euclid
Special Containment Procedures: Entrances to SCP-1918-2 have been secured and monitored with constant video surveillance as of 03/05/██. The sewage facility containing 3 entrances has been quarantined by Foundation personnel and the entrances themselves have been sealed. Workers previously employed at the facility have been issued amnesiacs and replaced with Foundation personnel. All other entrances have been permanently sealed with cement.
Description: SCP-1918 is an object of unknown composition located in what appears to be a utility room in SCP-1918-2. It appears to be a plastic mold attached to a metallic rod, and is usually found moving between hallways. SCP-1918 moves on its own volition, although it does not appear to separate from the ground at any time. The object leans in the direction it travels in, and moves at a set speed of 5 kph. The object applies moderate force to the surfaces it moves across, leaving a faint trail. SCP-1918 at times communicates using these carvings.
SCP-1918-2 is the designation for the facility containing the SCP-1918, and is located 12 meters below ground level, although the area itself appears to be undisturbed and shows no sign of an unnatural burial.
There are 18 identical rooms in the facility, or 9 compound rooms. Rooms are differentiated between a '1' room and a '2' room with crude carvings on the floors just outside of the individual rooms. The design of the facility containing SCP-1918 is mostly symmetrical, with .50 meter wide paths circling each compound room. The only deviations to this construction are the location of entrances on the sides of each individual room, which vary randomly while the facility is active.
Hallways in the facility are completely devoid of light, with any light produced being absorbed via an unknown mechanism; due to this, exploration must be performed via memorization of the facility interior and touch. Sound behaves abnormally within SCP-1918-2 while an event is active; An audible echo can be heard five (5) seconds after a sound (inaudible) is actually produced.
It is not currently known whether or not SCP-1918 and SCP-1918-2 are separate or identical manifestations as attempts to remove SCP-1918 from the SCP-1918-2 have been largely unsuccessful.
When a human or canine subject enters the central room it will become illuminated, and SCP-1918-2 will manifest. SCP-1918 will enter the room and moves across the floor, leaving in its trail a message either reading "Tik Tak Tow" or "Memoree", maintaining a consistent speed and leaving immediately after the messages have been inscribed. If the subject attempts to exit the room before this, the room will return to its dormant state, with the subject and any of its possessions disappearing immediately.
- "Tik Tak Tow" | The object moves to each “1” room, leaving behind "X" markings on the floors if the room is not already marked with an "O" in a manner similar to a game of "Tic Tac Toe". How a subject is meant to accomplish making a mark or understand this process is unknown, as no aides are given.
- "Memoree" | Upon exiting the room the subject is rendered unconscious by blunt force, presumably from SCP-1918. The subject regains consciousness in a random section of the facility. Success is marked by finding a “1” room identical to the central room. This event seems to possess a time limit, as the subject is pursued by SCP-1918 throughout the halls of the facility. The subject "wins" by marking the correct room with an "O".
Entering a “2” room causes SCP-1918-2 to enter a dormant state, and what is assumed to be the death of the subject participating.
If the subject is successful, SCP-1918 will present itself in the room that the subject is currently in. SCP-1918 will then inscribe "new game" on the floor and repeat the process with a new event. If the subject is unsuccessful, SCP-1918-2 will simply revert to its dormant state with the subject participating in the previous event disappearing.
History: SCP-1918-2 came to the attention of the Foundation after the disappearance of four utility workers in █████, a small town (pop. 226) in Maine. Numerous reports were filed to the local sheriff’s department of a “metallic scraping” beneath the ground, most commonly audible near sewage grates. Connection to SCP-1918-2 is non-Euclidian as entrances tend to be kilometers apart from one another. There are currently 9 known entrances, including 5 sewage grates, 3 utility shafts located in a sewage facility, and 1 toilet.
