Stella had to move far down the passage before the sounds of the waterfall dissipated. It was a fairly straight path full of stalagmite,s the ground slanted down towards where she was going. She'd gone around 200ft into the tunnel when she heard a strange sound from far ahead, it sounded like stone scrapping against stone. It would occur in uneven intervals like something was milling about with no real direction.<br/><br/><hr/>If you're heading into one of the passages I'll need a spot check too.
