The Thousand Oceans
The kopru are a race of heat-loving amphibians of great intelligence and power. Each has a smooth head, large eyes, and a tentacled, sphinctered mouth. Kopru have humanlike torsoes and two ending in webbed, clawed hands. From the waist down, their bodies consist of three fluke-like tails, each ending in a sharp ripping claw.
While they do not truly hate all men, kopru view humans as nothing but brutes to be used, played with, and controlled. Their expansion has been severely limited by their need for very hot, wet environments, such as hot springs and tropical swamps. Their civilization has been in decline for many years.
