Template:Ratings Metisette was a world in the 23 Librae system. It had a mostly Nitrogen atmosphere, but Methane was present as a liquid, forming the rivers and lakes of the planet.[1] The planet was used as a breeding ground by a Kig-yar named Reth, who bred hundreds of thousands of Unggoy, to send to The Rubble, and ultimately, to Earth.
