Level 9

Level 9 is the 10th level of the Backrooms. Discovered by u/Bart0nius, Level 9 is a set of 27 different rooms of the same size, like a sort of Rubik’s cube. There’s 9 rooms in a 3x3 shape on three different sets of “floors.” Each room is different, and are entirely random on what could be inside. Several Rubik’s cubes are mounted in carious locations inside of these rooms, and act as a sort of vague map of the level. The level will noticeably shift on occasion, one room that you entered from would likely be a different room were you to try to re-enter.

Description
As stated above, the level is a set of 27 ever changing rooms that resemble the model of a Rubik’s cube; and the rooms shift like one as well. As to what resides in these rooms, it is believed to be completely random; and constantly changing.

The Level is almost devoid of any life, the only entity being a blind humanoid monstrosity that u/Bart0nius refers to by the name Echo. The super-entity is blind, but navigates by using a sort of echolocation, hence the name. Any sound that occurs on level 9 will most definitely be heard and met by the entity; when it hears something loud it will come racing into the room at inhuman speeds, and violently thrash and tear at the sound’s location.

Exits from Level 9
The only exit known from Level 9 leads to Floor 11. It's found in a blue room with a door.
