The wiki basically described an accident inside Gestalt Factory, this is what I remember: one day the emergency alarm started to sound and the employees began to flee. But they couldn't use the elevator for some reason, so they went down the stairs. But DeathHorse ran into a lot of employees and ended up committing a massacre, and I don't think any of them survived.

I also remember that the text mentioned something about the number on the wall in the first chamber, which you can call.

It's very strange, but I remember reading it and that it was an official wiki. Although it disappeared or I simply can't find it anymore. If you know anything about this, have read it, or just want to ask a question, do it!
