allowed to read ████████████ (Appendix A) and said the creatures "sensed" were of humanoid size but otherwise similar to the massive green creature described.

Space-Time Anomalies

SCP-004 seems to propagate spatiotemporal anomalies. Personnel leaving the facility report losing time. Those who have been in the site for weeks insist that they had only been in the facility for several days, and records of work completed and supplies consumed support their claims. Other temporal anomalies involve SCP-004-2 through -13, especially the reappearance of SCP-004-CAS01 and SCP-004-CAS02 exactly ██ years after using SCP-004-██. ████████████████████ has been assigned to investigate all aspects of these time anomalies. Spatial anomalies include the impossibly large dimensions of the area opened by SCP-004-7. Similarly, the 2003 blackout incident suggests that there exists an alternate plane of existence within the same space that Site-62 occupies.

Additional Notes

Testing on SCP-004 reveals that ten of the keys open SCP-004-1 on a dimension where the laws of physics and topology are significantly different than those of our home dimension. Test subjects meeting these hostile conditions are torn apart, their body parts deposited in various locations, only three of which have been verified to be on Earth. Material deposited at two of these points appears immediately; material deposited at the third appears exactly ██ years into the future. The other seven locations are currently unknown.

Current testing focuses on two avenues of research. The first is finding ways to survive SCP-004’s hostile topologies. The second [DATA EXPUNGED] suggest that SCP-004-2 through -13 may open doors other than SCP-004-1.

Appendix A: Mental Health Effects of SCP-004-12

All Class D personnel using SCP-004-12 return in a catatonic state, unable to speak. Some may have enough energy left to try to claw out their eyes. Of the 16 subjects, only 4 have survived. Only one has regained speech, following long-term psychotherapy. He was able to tell the psychiatrist that he saw a massive green creature, so large that much of its body extended beyond his field of view. He reported innate fear and sudden recognition, “as if it were something buried deep in [his] primal fears,” and forced implantation of “incomprehensible” memories. Subject displays acute anterograde and retrograde amnesia.

Appendix B: Additional Information

Item #: SCP-004-14

Date of Discovery: 09/02/1950

Origin of Object: Object was discovered elsewhere in factory area, in the previously undiscovered manager's office.

Description: Object appears as a large, unvarnished wooden box. The box may be unlocked by the "safe" key, SCP-004-7, as well as five of the "unsafe" keys (see Document SCP-004-1).

Upon unlocking SCP-004-14 with SCP-004-7, the box opens automatically on hinges. The volume of the space inside is precisely five times greater than the outer dimensions imply. Items placed within while the lid remains open do not affect the weight or any other properties of the box. When the lid is closed and locked, however, all items inside vanish irretrievably. Personnel locked inside the box are also irretrievable, although losing personnel in this fashion appears to affect significantly the dreams experienced by [DATA EXPUNGED].
