Human: Generate for a foreboding scene outside a coastal area cliff with steam, rock, and lava flow. Assistant: 
The ledge is wet and hot to the touch. Just holding on is a chore, and blasts of steam slap against the rock as if hoping to tear all life away and hurl it into the vengeful maelstrom. Down below a dark opening seems to lead to a tunnel from the crashing surf, for every now and then a great wave crashes in, only to be vaporized almost instantly as it meets the lava flow.
