Koprus are a degenerate race of heat-loving amphibians. Though they possess intelligence and power, their civilization has been in decline for generations.Evidence suggests that koprus once boasted a powerful undersea culture. They mastered psionics and built an extensive cities. But climactic shifts or increased competition from other marine races started these creatures on a descent into barbarism that continues to spiral.The expansion of kopru society is severely limited by their need for extremely hot, wet environments (such as volcanic hot springs).Adventurers tell of finding ruined kopru cities on the ocean floor, filled with exotic treasures and occupied by monstrous marine life. Scholars guess that the kopru ability to read a charmed creature’s thoughts may be the last remnant of the psionic abilities so common during their days as a civilized power.Koprus view humans as brutes to toy with and control. They stalk strangers that wander into their realm, then attack at the victim’s most vulnerable moment. Their society is described as being "matriarchal and savage".The kopru, a man-sized creature with a humanoid upper body, has a smooth head, large eyes, and a tentacled, sphincteral mouth. Its two arms end in webbed, clawed hands, and its sinuous lower body splits into three fluke-like, prehensile tails, each capped with a sharp hook. Kopru skin, light tan at the creature’s hatching, gradually tums to olive in adulthood and fades to a sickly brown in old age. Instinct: Charm and enslave intruder
