Lord of the Backrooms

"If you accidentally noclip out of reality in the wrong place, you'll end up in the Backrooms."

"Nothing but the stench of damp carpet and the maddening monotony of yellow..."

"The endless hum of fluorescent lights running at full power, and roughly six hundred million square miles of randomly divided, empty rooms to get lost in."

"If you hear something wandering nearby, may God help you, because it has surely heard you too..."

"..."

"Customer service? Where's the live customer service on this site?!"

"Hello, sir! This is the Level 7 territory hotline operator. How can I help you?"

"The stuff in your post is completely fake!"

"At the destination on the map, I found nothing but a huge gate. Inside was a whole lot of stuff I couldn't make sense of: roads that drifted by themselves, trains flying through the sky, enormous gates leading to different levels, and shopping streets packed with residents from every level..."

The caller suddenly paused.

"Wait, why is an Entity lining up in front of the gate?!"

"There's something wrong with your Backrooms, isn't there?!"

P.S. You don't need to know the Backrooms, and this is easy to read. An original take based on the Wikidot Backrooms, following the principle of "one is never two, and two always follows one."
