The Seven-Part Continent

A prank turned sea and land upside down: seven parts continent and three parts ocean. The places where humans can survive became lowlands that were once the ocean floor, while seawater piled up over the continents and would not recede. In this world, water flows backward. Civilization is primitive, and humanity struggles to survive in the lowlands, battling mutated land-dwelling fish. The continents are submerged, and dragons prowl the shallow seas. Oceanic magical artifacts, magic stones, practical science for the reversed waters, dragon-slaying families, and the fish-people of Atlantis will all make their appearance.
