On the other side of the mountain ranges lie steep cliffs dropping off from the high peaks. Delved into the sheer rock walls are large caverns and smaller caves. The larger caverns are filled with markets, communal springs, and other such areas. The smaller dens are homes to the residing dragons, the only creatures willing and able to reach the caves. It doesn't help that far below the cliffs huge ocean waves crash into the sheer surface, warding off even more unwanted visitors... except for the mermaids living within the deep waters.
