Kolto
this healing agent was harvested from the oceans of the planet Manaan more than 4,000 years before the Battle of Yavin. Because Manaan was the only known source of kolto, it was highly desired during the Great Sith War, making Manaan one of the most influential planets in the galaxy despite its relative insignificance. The native Selkath who produced the kolto maintained strict control over its production, realizing its worth to the galaxy and working to ensure neutrality in making it available. When production mysteriously halted, the Selkath appealed to the Old Republic for help. Since Manaan was not officially a member of the Republic, help was neved dispatched to the remote world. Since that time, kolto production had steadily recovered, but the Selkath vowed never to allow outside influences to control their planet or the production of kolto.
