Pierin

The Pierin are a space-faring species in the Known Space universe created by writer Larry Niven and others.^[1]

In the books, and games inspired by the books, they are a rare multi-limbed species that developed on a planet with lower gravity than Earth, thus they spend much time in the air. They have horns on their heads and wide membranous wings. They speak in raspy screeches and atonal clicks. Pierin are described as curious and friendly to the point of being nosy. They were able to develop a small space-faring civilization before being enslaved by the Kzin.

Their planet of origin is known as Pierin, orbiting a star in the constellation Reticulum. At some point Human beings tried to ally with them against the Kzin. They eventually were liberated from slavery during the Man-Kzin wars.^[2]
