Homebrew Abyssal Merfolk Species Details

Abyssal depths merfolk live among the Abyssal depths of the ocean, between 10,000 to 20,000 ft under the water's surface. They often have humanoid torsos joined with the lower halves of cephalopods or deep sea fish, such as octopus, squids, lion fish, or sharks. These merfolk typically reside in strange non-euclidean cities built into the walls of abyssal depth trenches, and are very rarely seen on the surface.
