You seriously start to doubt this man and stray from his lead. The man seems to really want you to turn around and continue following. You ignore the man and continue, the man leaves as if to say “your loss”. As you get farther into the vent, it gets darker and darker. You feel the walls for a place to turn but the small hallway only goes straight. You hear a slow, big fan in the distance. Your hand finds an empty space in front of you; you loose your balance and fall. You hear the sound of the fan getting closer by the second. It would take a ton of luck to make it out on the other side of the fan alive. The good news is you somehow pass right through the fan just fine. The bad news is that your momentum from the fall was enough to break the bottom of the vent that you fell on and suck you into the blackness of space. I think we all know what happens next.
