Help Atlantis

Far beneath the surface of the ocean, a civilization flourishes. Merfolk
fish and swim and play and shop.  Unbeknownst to them, their god, Neptune,
has been angered. Neptune's cleric has received visions of the end of the
world. He is searching for someone, someone who can save them. Will that
person be you?
