Feeling his surrounds by way of sound was bliss. Hell, that may be a dangerous mission, but he is almost enjoying it.
@Team: Guys, I can sense the caves quite well. I believe the structure is really good at reflecting ultra-sound waves. Listen: the tunnel to our right, leads to the crossing, and taking the west way there's a dead end - rubble from a cave in, if you rely on my guess. The east path is what amuses me: a round "room", with smooth walls. It's sounding echo is a lot more precise than the other parts... About the other way... well, I just lose responses, so it must stretches farther away.
