Selkath

The Selkath were a sentient aquatic species, native to the ocean-covered planet of Manaan. Since Manaan was the only naturally occurring source of kolto, the Selkath held great diplomatic sway during the Jedi Civil War. At that time, they held tightly to their neutrality; however, a few farsighted Selkath occasionally broke their neutrality in secret, and arranged deals to help their preferred side. Eventually, the kolto market disappeared and the galaxy abandoned the Selkath. It was not until the rise of the Galactic Empire that the Selkath would have interaction with the galaxy again. They were later conquered by the Galactic Empire.
