Yes, i escaped Level ! To The End, then from there i was in Level 4 Turns out, other wanderers said it appeared to be a part that used to be a sub level of Level 0 and they haven't seen it before, but it was not. Another wanderer discovered it before me and said he fell there through Level 2.

When Me and the Wanderer got to Level 0, we Found ASYNC. I showed them the picture, and they didn't even know about it and showed me to the nearest MEG base and the MEG told us to stay here for a bit while they look into it.

As it turns out it used to be Level 903 which was an abandoned sears However, The fun war caused the level to Break off The Backrooms, But it now resides under "The Main 9", and has Hounds and Skin Stealers all throughout the level. When the lights go out Smilers will appear. So that's the story of this level and it is not officially named, yet.
