Item #: SCP-XXXX
Object Class: Azrxi
Special Containment Procedures: Full cooperation with SCP-XXXX has been deemed a Black-level priority by the O5 council, as SCP-XXXX does not have the full capability to contain SCP-XXXX-C, which will cause a ZK-Class Reality Failure event if not contained. SCP-XXXX-A are to act as "natives" under the cover of an undeveloped island, and are ordered to fire at any intruders. Only those with Level 4 clearance and above are allowed to know the true nature of SCP-XXXX, and SCP-XXXX's cities are censored from maps of North Sentinel Island under the guise of jungle.
SCP-XXXX-C is to be contained in a 10 m3 electromagnetically held steel and uranium-238 lined containment cell with a thickness of 1 meter located in SCP-XXXX-B, with said containment cell henceforth referred to as Chamber A. Chamber B is to consist of at least 20 meters of empty space between Chamber A and Chamber C. Chamber B is separated from Chamber C by a uranium alloy steel wall with a thickness of 40 cm. Chamber C consists of the control room and a final protective layer of 10 cm thick uranium alloy steel. No less than four (4) armed guards are to be present near Chamber C at any time. Emergency warheads are located behind Chamber C and may be used under the discretion of SCP-XXXX and the O5 Council.
Description: SCP-XXXX is an anomalous civilization currently located on North Sentinel Island. Though first recorded around the 11th century by various Indian kings, SCP-XXXX was not known to exist on North Sentinel Island until an MTF expedition in 1888 to said island. After the discovery of SCP-XXXX and SCP-XXXX-B and -C, an agreement was made between the Foundation and SCP-XXXX to assist SCP-XXXX-C containment.
SCP-XXXX-1, the inhabitants of SCP-XXXX, appear to be Pongo abelii orangutans, yet consist of a highly developed civilization due to SCP-XXXX-C's effect. Autopsies have confirmed them to have human-like vocal chords, and a thick Indonesian accent has been noted from those conversing with SCP-XXXX-1. SCP-XXXX-1 has its own language (publicly known as Sentinelese) yet is capable of conversing in most known languages, including English. They appear to be highly intelligent, with an average IQ of 135.
SCP-XXXX-A are humans seemingly "serving" SCP-XXXX. Though they appear to be mostly non anomalous, SCP-XXXX instances have full control over there actions, with a telepathic link being confirmed in interviews. SCP-XXXX-A instances, have, since 1888, served as guards to North Sentinel Island under the guise of aggressive natives.
SCP-XXXX-B appears to be a military base located under the center of North Sentinel Island, operated by SCP-XXXX with assistance from the Foundation. The main purpose of SCP-XXXX-B is to contain SCP-XXXX-C, though several other Safe and Euclid-class anomalous items were stored there before confiscation by the Foundation in exchange for SCP-XXXX-C containment.
SCP-XXXX-C is a [DATA EXPUNGED]. Discovered by SCP-XXXX a few years before the Foundation first conducted an exploration of North Sentinel island, SCP-XXXX-C appears to have created a temporal anomaly where all events on the island are contained within the 1,000,001st century, explaining SCP-XXXX's technological process. It has almost caused a ZK-Class Reality Failure Event numerous times, and containing it is to be considered a Black-level priority.

<Begin Log, 11/12/1999>
Interviewer: Hello there, Mr. Jomaaciasopq. How did SCP-XXXX discover SCP-XXXX-C?
Jomaaciasopq: That thing? (visible shivering) We found it, like 120 years ago, deep in the forest, All it wanted to do was [DATA EXPUNGED], and we became really advanced, enough to contain it so it didn't blow up the whole multiverse or something. We had it breaking out too many times, we were thankful that you came here. We only had to deal with that thing, and not the other horrors in there. Point is, you were our saving grace.
Interviewer: Just asking, what is the time again?
Jomaaciasopq: Soon, there will be no time.
