Description
Level 0 is an expansive non-Euclidean space, resembling the back rooms of a retail outlet. All rooms in Level 0 share the same superficial features, such as worn mono-yellow wallpaper, old moist carpet, scattered electrical outlets, and inconsistently-placed fluorescent lighting. Aside from these common features, no two rooms within the level are identical.
The fluorescent lighting present in Level 0 hums at a constant frequency. This buzzing is notably louder and more obtrusive than ordinary fluorescent lights, and examination of the fixtures to determine the source has been inconclusive thus far. Secondly, the substance lightly saturating the carpet cannot be consistently identified; it is not water, nor is it safe to consume.
…But you aren't here to know that, are you? You've heard this same spiel a thousand times.
Entities, descriptions, colonies, over and over again through a thousand different levels. You're looking for a way out. Something, anything, that could lead you home.
Do you remember the first time you found a new level, anything to break up the monotony? It was one level. Then two. Then three.
Then a thousand more.
Entities
There are no entities here.
No colonies, no people, nobody but you.
You are alone.
Entrances and Exits
Entrances
You've been searching for the exit for a long time, haven't you? How long has it been since you've seen another human being?
Your group has left you. Most found safer places to spend the rest of their lives, better places. Some died, either by an entity, by the environment, or starving when resources were low. Others simply disappeared, never to be seen again.
The levels decreased in documentation, and increased in difficulty as time went on, each level posing new challenges as you went on. You went deep into the Backrooms, too far to comprehend.
You've gone so far...
And yet you are right back where you started.
Exits
Don't you see what you're doing to yourself? In the process of trying to escape, you're slowly killing yourself. Your body, your mind, your soul.
Even if you could leave, what would you have to go back to?
Do you still remember your friends? The place you lived in? Do you remember your family's faces? You've likely been presumed dead by now. They have forgotten you, and you have started to forget them as well.
There is nothing left for you.
Lay down on the floor. Look at the buzzing fluorescent lights for the last time, and close your eyes.
Let your fragile life fade away.
