A cassette tape, known as SCP-407, was discovered in a university professor's room, which had transformed into a rainforest. The tape contains a 28-minute song in an unknown language that accelerates cell growth, initially causing a miraculous cure for various physical maladies. However, prolonged exposure leads to uncontrolled cell growth, resulting in the creation of a new ecosystem, including the growth of anomalous plants and a deadly, parasitic fungus, similar to Cordyceps. The SCP Foundation conducted two tests, both resulting in catastrophic consequences, including the death of the test subjects and the takeover of the testing chamber by the fungus. The origin of the song and the fungus remains unknown, but it is believed to have the potential to cause an XK-class end-of-the-world scenario. The anomaly was eventually neutralized by a member of the Serpent's Hand, a group that opposes the SCP Foundation, who hacked into the foundation's database and deleted all records of SCP-407, effectively neutralizing it.
Here are the facts extracted from the text:
1. A local landlady called the police in a state of hysteria, reporting a horrifying incident involving one of her tenants.
2. The police found the tenant's room filled with trees, plants, fungi, insects, and animals.
3. The tenant, a university professor, had recently gone on an anthropological expedition to the Amazon rainforest.
4. The professor was nowhere to be found, but a large colony of anomalous mold was growing on the far wall of his room.
5. A human skull was sinking into the tissue of the mold, with tendrils slithering from the empty eye sockets.
6. The SCP Foundation took over the situation, containing the anomaly and giving amnestics to the landlady and other witnesses.
7. The Foundation discovered an unmarked cassette tape in the professor's room, which was later designated as SCP-407.
8. SCP-407 is a 28-minute recording of a song in an unknown language, sung a cappella style by a group of unknown individuals.
9. The song has anomalous effects, accelerating cell growth within its auditory range.
10. If played for more than a minute, the song can cause benign tumors and calcium and fat deposits to form on the skin.
11. At around 4 minutes, single-celled organisms in the area begin to experience accelerated mitosis, leading to bacterial and fungal growth.
12. Beyond 5 minutes, the song's effects become truly monstrous, with plant growth becoming uncontrollable.
13. The Foundation conducted two tests with SCP-407, both of which resulted in catastrophic consequences.
14. The tests revealed that the song can cause a subject to devolve into a blob of pure flesh, surrounded by a lush rainforest of alien plants.
15. A parasitic fungus, similar to Cordyceps, appeared in both tests, consuming everything in its path.
16. The fungus was found to be similar to one encountered by SCP-507, a man with dimension-hopping abilities.
17. SCP-507 had briefly hopped into a dimension where the world was covered in the same mold, with nothing left alive.
18. The Foundation tested the samples of the mold and found it to be a highly evolved and deadly version of the Cordyceps fungus.
19. A person of interest, nicknamed LS, deleted all records of SCP-407 from the Foundation's database.
20. LS is a group of the same person from different dimensions, who meet in the Wanderers' Library to coordinate their missions.
21. LS likely knew about a universe where SCP-407 had caused an XK-class scenario and destroyed the world.
22. The Foundation's policy is typically to contain rather than neutralize anomalies, but in this case, they may have been better off neutralizing SCP-407.
