The fissure opens into a massive pit filled to the rim with a viscous grey-green fog. A steady howl echoes from the unseen depths, despite the air's deathly stillness. Wispy tendrils of fog emerge from the chasm, dragging along the edge of the gaping sinkhole like unseeing hands reaching out to explore their surroundings before sinking back into the frothing mist.
