Item #: SCP-636
Object Class: Euclid
Special Containment Procedures: What remains of SCP-636 requires little space, but it is still recommended that containment chamber measure at least four (4) meters in diameter. Security needed is minimal, and SCP-636 is to be inspected by one (1) Class D personnel twice weekly. SCP-636 requires no further study, as all useful data is believed to have been collected. (NOTICE: See Document# 636-21 (attached) for obsolete Procedures.)
Description: SCP-636 is at present time made up of a collection of metallic fragments resultant from events detailed in Document# 636-27 (attached). Forty three (43) distinct fragments are cataloged, their exact information kept on file [DATA EXPUNGED]. The largest fragment is a section of the original ring, with mass of twelve point six (12.6) kilogrammes, and an approximate length of point two five (.25) meters. The fragments are comprised mainly of a mixture of tungsten and carbon, with ratios unequal to commonly used tungsten-carbide. Several pieces are of unknown composition, with atomic masses not successfully replicated in terrestrial experiments. Original description can be found in Document# 636-5 (attached).
Also contained with SCP-636 was one (1) disk fragment that was found later to be an information storage device, accessible using post-1990's computer equipment. After decryption and translation of the unknown data format the disk was found to contain schematics for devices theorized to be weaponry of unknown origin, as well as information that gave a analysis of the engine core in a maintenance capacity. Attempted production of devices described has proven futile using current materials. Two (2) copies of the information have been made, both classified and stored at sites [DATA EXPUNGED] and [DATA EXPUNGED] respectively. No other information was recovered due to the damaged state of the piece, and any further attempt to access the original disk has been futile since the event in Document# 636-27.
Document# 636-5:
“SCP-636 was recovered on the night of July 7th, 1947, in the fields near Roswell, New Mexico. Physically, it has the appearance of a rotating torus, orbiting a sphere. Attempts to change location of the torus in respect to the core have proven futile, as they appear to be somehow nonphysically connected. Attempts to influence the velocity of the rotation have also proven futile. However velocity does appear to be subtly increasing, corresponding to the countdown of a small timer, operating in standard Arabic numerals, set in one side of the sphere. The timer was originally found at 18,994, and had decreased to 18,993 within 7 hours of recovery. Countdown rate is very nearly one tick per day, although it is not exactly every 24 hours.” - Dr. ███████ █████
Document# 636-21:
"Recommended safety procedures recommend isolation, save for two class D personnel to be stationed within a 75' by 75' room, with the device at the center. At current time, the device has proven benign, but stationing non-expendable staff is an unacceptable risk. At the point that the timer reaches 30 ticks remaining, it is recommended that security be drastically increased, with as many as eight class D personnel stationed within containment, and between twelve and twenty level two personnel stationed outside in full protective equipment." - Dr. ███████ █████
Document# 636-27:
"On February 29th, 2000 at approximately 0300 hours Greenwich time, the device labeled as SCP-636 underwent what is described as a self-destruct sequence. As outlined several decades ago in Document# 636-21, eight expendable class-D personnel were stationed inside the room, with sixteen level two personnel stationed outside in Mark IV protective suits. Overseeing the situation were agents ███ █████████ , ████ ████ ██████████, and ████ █████ working in 8 hour shifts. The event occurred during the shift of [DATA EXPUNGED], and his report has been filed with [DATA EXPUNGED]. The explosion of the device was immediately fatal to the two class D positioned nearest the device, at about 3 meters away. Three others were severely but non-lethally injured by the explosion, and all within the room were moderately injured by resulting shrapnel. The level 2 security force secured the room, but no further events occurred. All fragments have been collected and cataloged, and the surviving D personnel were terminated following uneventful questioning. Attempts were made to repair fragments of the core using data from the originally recovered disk, and one fragment was successfully re-energized and is being used to facilitate the powering of [DATA EXPUNGED]. All other fragments remain inert, and are to be considered non-harmful, though they will remain Euclid class objects due to suggested possibility for future danger." - Agent ███ █████████
