This rocky coastline was once the site of a great volcanic eruption, and the porous black rock that remains is more prone to erosion than many other beaches. Where it has eroded entirely, the sand is inky black; where rocks still form promontories out into the ocean, its natural hollows and crevasses have expanded. At high tide, they are underwater; at low tide, they form pools that are home to a wide variety of crustaceans and small fish. The local orcish tribe often reports merfolk sightings near the pools. While the merfolk are elusive, it is theorized that they enjoy the urchins and starfish that live there as rare delicacies. If this is true, however, they never take so many that the creatures cannot come back the next time the tide rushes in.
