Stairway to Hell

Publisher's blurb: A gigantic skull sits central on a platform of ancient stone, four paths span the lava filled chasms that surround this skull one path however has broken over the ages and now a gap lies between. The desolate landscape spans out to the horizon and noxious gases rise up from the roiling magma below. Within the ancient skull lies a spiral staircase that descents deeper and deeper into the earth.
