Fastitocalon (Monster)

An incredibly rare phantom fish that swims through the sand. It hides in the sand, and attacks once its prey approaches. It is believed that they adapted to swimming in sand to escape from the many carnivorous predators of the sea, but how they are able to swim and thrive in the sand is unknown. They appear out of nowhere to attack, with reports of casualties from adventurers and commoners alike, so try to exterminate as many of them as possible.
