The Kopru are a savage amphibian race who once ruled a great undersea empire. Although reduced to scattered clans of barbaric hunters, they retain their cunning, ambition, and powers of mental domination.


Slightly over seven feet in height, the Kopru appear as horrid, walking fish-men. They have vaguely humanoid bodies with webbed and clawed forelimbs and a bulbous yellow-eyed head, with a long barbed tail.

Their horrific fish-like faces feature a lamprey-like maw filled with sharp teeth. The glowing, yellow eyes of a Kopru can instantly hypnotize any creature and force it to the do the bidding of the Kopru who gazed upon it.


Kopru have a matriarchal society in which powerful female shamans or oracles lord over loosely-organized colonies made up of between a few dozen and a few hundred Kopru.

Female Kopru are predominantly divine or arcane spellcasters, while males are either stealthy rogues or as brutal warriors.

Kopru thrive in very hot conditions and prefer to lair near volcanic vents, but as aquatic creatures, their lairs and colonies are always located adjacent to a source of water

Each Kopru colony will always contain an assortment of slaves from various other aquatic races, including; Merfolk, Sea-Elves, and Locathah.


The Kopru have always been fanatically devoted to the demon-lord Demogorgon, whom they believe created them and blessed them with their mental powers. The creatures consider him a deity and though his divine favor, they once built a great under-sea empire.

Long ago, the Kopru Empire spread across all four oceans of Oris. Their underwater cities were built near ocean currents which facilitated quick travel across vast distances. In their empire, Kopru priests of Demogorgon long served as the ruling class.

Roughly 3,000 years ago, the Kopru empire collapsed after a period of natural disasters and several unsuccessful wars with the hated Aboleth.

Over the centuries, the Kopru abandoned their cities and became scattered across the under-sea world, where they dwell in seclusion, harboring old hatreds and plotting various dark schemes. All Kopru dream of one day controlling the oceans as they once did, but their powers have long been eclipsed by the far more powerful Aboleth.
