 There's a sickness in the back rooms and it's spreading everywhere. That's right, entity number 19, or the disease, is a very dangerous infection that lurks deep in the hallways of the back room's levels. It's mainly been seen in dark and damp places like old wallpaper or places with standing water or piles of entity corpses. If you come into contact with one of those and you think you have the disease, you'll start to have symptoms like irritation, dehydration, stomach problems, rashes, and auditory hallucinations. If you have these symptoms, well, it's probably over for you, if I'm being honest, because after four days of contact, you're a lost cause and you'll begin dissolving from the inside out. No one knows where it came from, why it's there, or if the back room's itself made it, but we do know that you have to avoid it at all costs because you don't wanna be corroded from the inside out. What are your theories on it? Let me know in the comments below.
