Dense fog rolls its way up to the makeshift ceiling of crumbling basalt, riding cold blasts of chilling air rising from the inky darkness far below. Faint illumination filters through fissures in the jet-black stonework, giving life to the deepening shadows as the light reflects off the swirling mist and vapor-moistened walls. A soft whisper rises in volume to a cacophonous howl as cold wind rushes quickly up from the depths, only to be followed by a haunting stillness.
