Item #: SCP-3XXX
Object Class: Euclid
Special Containment Procedures: All staff are to be informed that SCP-3XXX does not exist, has never existed and will never exist. Any staff members that claim anything about SCP-3XXX other that it's nonexistent nature are to be terminated, and any who heard, read, who could lip-read that staff member violating this procedure must receive class-c amnestics. Any sentient beings, semi-sentient beings, or intelligent beings that understand language to any degree that have previous knowledge of SCP-3XXX before ██,██,████ must also be amnesticized, and any sentient beings cannot be amnesticized must be terminated. This includes high ranking members of the foundation and other SCPs. Any documents, recordings, or vague references to data stating anything about SCP-3XXX other than it's lack of existence must be corrected and then destroyed.
Description: SCP-3XXX does not exist. SCP-3XXX has never existed. SCP-3XXX will never exist.
SCP-3XXX is not/was not/never will be sentient or remotely intelligent, because it does not exist. SCP-3XXX has no mass, weight, volume, height, width, or length. SCP-3XXX does not exist. SCP-3XXX does not, cannot, and will never possess any abilities outside its existence. There are no references to SCP-3XXX in any religious texts. There never was. SCP-3XXX has never existed, so there was nothing to write about it. SCP-3XXX has no anomalous properties other than not existing.
Addendum: It's not enough to say no one has ever written about it. We need to keep looking for any reference to it in any literature in the world. Any sacred text, and scientific journal, any blog post, and any cave painting about it, but be corrected and then destroyed, because if we don't, someone will see it. Someone will think about it. If that happens, it will come back. But it won't. Because it can't. SCP-3XXX does not exist.
