The Lirin were a war-like species originally native to the planet Liris II.
They were known for having a highly xenophobic view of most species, believing themselves the only true intelligence. Their conquered included the Latigans, the Tirrion, the Comacans and the Halaxan, who they mostly experimented on.
This ended when the Terran Federation went to war against them for their attack on a freighter close to their territory in 2153. The Lirin were severely defeated and retreated back to their homeworld. Two months after the war ended, the star in their home system went supernova, destroying their homeworld and billions of people. Several hundred thousand managed to escape however, and ironically settled in Terran Federation space.
