The Backrooms (Basement)

I experienced the basement, and here's what I've seen. I saw a broken stairway to 4 walls with a small fireplace on it. Appearently you can climb up the chimney, but it's nearly impossible. It took hours, but I managed to do it. Now I snapped back into reality. I also saw a table with at least 100 papers. Some people who been there wrote on them with their blood. There's a blank room with a creature who doesn't like visitors.
