Creatures of FASA

FASA 365 Day 221 Oram Monstrum Exesum (Coastline Erosion Monster) 300 ft or more.
A classic tale of Itch and Scratch.
The scales on this beast, both the large and the small, are incredibly irritating to the animal. So, like any other animal, he seeks relief wherever he can.
Most Sea walls can be attributed to the Oram Monstrous rubbing up against them.
The rubbing and scratching does lead to the dislodging of the scales, but the erosion of the seawall, and any castle or structure that was inadvertantly built there as well.
You may ask about the scales.
You would think that they must be a highly sought after resource. And you’d be right… If anyone could figure out how to retrieve them from the ocean floor.
