The SCP Foundation discovered an anomalous cave, known as SCP-2935, which served as a passageway between dimensions. Following a distress signal, the Foundation sent three manned missions into the cave to investigate. They found a mirror dimension where a mysterious event, known as the "Extinction Event," had caused the sudden and total death of all living organisms. The Foundation's teams discovered the perfectly preserved corpses of people and animals, including other SCP entities, with no signs of decomposition. As they delved deeper, they realized that the event had occurred simultaneously across all dimensions, and that the cave was a conduit for "absolute death" to pass through. The final mission ended in catastrophe, with the team discovering a nuclear failsafe and inadvertently triggering it, sealing themselves inside. A message from one of the agents revealed that the entity responsible for the event was the specter of Death itself, which had followed them back through the cave. The Foundation sealed the entrance to SCP-2935 to prevent Death from entering their dimension, and now keep it under constant watch, aware that they have no power to stop it if it were to break through.
Here are the key facts extracted from the text:
1. The SCP Foundation is an organization that discovers and contains anomalous information.
2. On April 28th, 2016, the SCP Foundation encountered an anomaly known as SCP-2935.
3. SCP-2935 is a passageway between two dimensions, discovered in an unincorporated area of Joppa, Indiana.
4. The passageway was found in an abandoned cemetery, with the most recent death on any tombstone recorded as being over 100 years ago.
5. A drone sent into the cave appeared to exit out the other side, but the area it observed was greyer and lacked life.
6. A team of Field Agents, known as Manifest Destiny, was dispatched to investigate the anomaly.
7. The team discovered a farm house in the mirror dimension, with perfectly preserved corpses of a family inside.
8. The family's last meal was still on the table, with no signs of decomposition or obvious cause of death.
9. The team found an opened newspaper dated April 19th, 2016, suggesting the family may have died a full eight days before the discovery.
10. A second expedition, codenamed "Overland", was sent to investigate the mirror dimension's Site 81.
11. The team found the perfectly preserved corpses of every member of the Foundation at Site 81 in the mirror universe.
12. The corpses had experienced complete and sudden death on a cellular level, with even bacteria dying with them.
13. Death was total and absolute across all types of life forms in SCP-2935.
14. The team discovered their own corpses in the mirror universe, in roughly the same spots they had been inside Dimension Prime's Site 81 eight days prior.
15. The team found that all the mirror universe SCPs, including SCP-682, were dead.
16. A third expedition, codenamed "Nineteen", was sent to investigate the mirror dimension, but they accidentally activated the base's on-site nuclear weapon.
17. The team was locked and sealed inside Site 81 and incinerated in the nuclear blast.
18. The automated drones returned to Dimension Prime with footage and information gathered from SCP-2935, but it did not illuminate how or why the Extinction Event occurred.
19. The Foundation discovered a final encrypted audio log from Agent Keller, describing the event in a third dimension.
20. Keller believed that whatever caused the event in the third dimension had followed him back into his world, and history repeated itself.
21. The Foundation decided to seal the entrance to SCP-2935 with concrete and keep it under constant watch to prevent the entity from passing through.
