The interior of SCP-4558.

Item #: SCP-4558

Object Class: Keter

Special Containment Procedures: SCP-4558 is cordoned off from public access under the guise of a military installation. Research on SCP-4558 is based in the nearby Site 312.

Expeditions into and testing of SCP-4558 are currently in the planning stage suspended by order of O5-5.

The apprehension of PoI#8161, #8162, and #8163 is a top priority. Surveillance of the Church of Maxwellism indicates that PoI#8161 is currently living somewhere in the Western United States; the locations of PoI#8162 and #8163 are known.

Description: SCP-4558 is an underground supercomputer located across the border of Nevada and Idaho. SCP-4558 extends for 5km underground and is 5km wide at its greatest extent.

The entrance to SCP-4558 is a large concrete bunker built into the surrounding desert environment. Inside is a ladder leading to a central "interface" chamber, where SCP-4558 can be directly interacted with through a series of monitors and input devices. The phrase "THE MANY INTO THE ONE" is carved on the chamber's ceiling. Extensive damage to the systems and memory of SCP-4558 is evident; despite this, SCP-4558 appears to be broadly functional.

Exit from the central interface chamber is possible through a large octagonal shaft located in the centre of the interface room. At the bottom of this shaft is a pentagonal chamber with five doors, one on each wall; four of these branch off into separate compartments containing SCP-4558's extensive hardware. Entry to the fifth room has not been achieved. Entry to the fifth room will be achieved. Information on other areas of SCP-4558 is limited pending a planned expedition by MTF-Epsilon-101 "Four Lights".

SCP-4558's purpose is unknown, but extensive Foundation investigations indicate that it was originally designed by members of the Church of Maxwellism. Planning for what is now known to be SCP-4558 has been found in archived Maxwellist forums and chat logs in 1995, before senior Church leadership decreed such discussions "heretical". Prominent figures in this early planning include users with the handles "onewan1", apparently the project lead in these early stages; "holy_fibr5", believed to be the project's lead programmer; and "tbgeuse", who was tasked with formulating "defence mechanisms". These individuals have been designated PoI #5555, 5555, and 5555 respectively. An individual known as "C.H. Jones" is also believed to be connected to SCP-4558; he has been designated PoI#5555.

No record of SCP-4558 can be found after this until its discovery by the Foundation on 2015/05/15; evidence collected from SCP-4558 suggests that work on the present structure could not have begun before 2005.

Addendum 1: The following documents are excerpts of a book found within the interface chamber of SCP-4558. Due to heavy infohazardous properties, only the following excerpts are readable.

Addendum 2: On 2015/08/19, the planned expedition by MTF-Epsilon-101 "Four Lights" took place. A log of this expedition follows.
