The Cave's natural environment is total darkness. A darkness so devoid of ambient light you can only find it deep underground and leagues under the sea. It feels like a thick, black woolen cloak on a foggy night's stroll. The weight of it presses down on your back gently. It's warmth off setting the drooping gravity of it as it tries to slowly envelope you. I find I am being drawn into it, carrying only my tiny shielded flash light as I hum my way along the passages alone.
