Item #: SCP-0000

Object Class: Euclid

Special Containment Procedures: TBA

Description: SCP-0000 is an extensive subterranean facility located on the surface of the Moon. It is accessible only through a metal hatch located in the Lacus Hiemalis. Despite presumed extraterrestrial origins (see exploration logs), the architecture of SCP-0000 is not noticeably different to that of human structures.

The interior of SCP-0000 does not follow a consistent layout.

SCP-0000-A refers to an electromagnetic field generated within SCP-0000 that obstructs any radio signals passing through it. For this reason, any units operating on the surface of the moon will be unable to communicate with Earth, though radio communications between lunar operatives may still take place. As of [log number], SCP-0000-A has been taken down, rendering the preceding paragraph irrelevant.
