Coral Riffs

Geographic location in Globiuz. Mysteirous, floating mermaid riff, located in the pits of the Grand Ocean. Some sailors refer to it as an Esper town, that floats only its upper crust over the ocean waves. Others tell, that there is a whole underwater city, radiated with bulb-lanterns at its coral arches. Probably, inhabited by amphibians or spooks. Only those, who can breathe long enough, could access it. Sailors shun away from this 'cursed' spot.
