Regaining consciousness you smell the damp. Opening your eyes you see the stone walls of the chamber flickering by the light of the fire; you stumble to your feet and kick a helmet clattering across the floor.

You put the helmet on, adjust the beam-width and proceed into the abyss. (scanner-sombre.com)
