Russ Exposes The Tunnel
Hissing. (could be an animal)
Auditory: Someone walking through the tunnel towardus. Very defined sound of footsteps.
Noted green slime on wall on outside of tunnel.
Noted banging noises inside of the tunnel.
Noted strange watermarks on the walls in the shape of three human figures, two soldiers, one person hanging. (could be coincidence but it was neat to look at)
