Manaan

Manaan was an aquatic planet that was the homeworld of the Selkath species, who tended to their native oceans. The Selkath bounty hunter Mantu hailed from Manaan.

Behind the scenes
Manaan, along with the native Selkath, first appeared in the 2003 Star Wars Legends video game Star Wars: Knights of the Old Republic. Manaan became a part of canon after it was mentioned as Mantu's homeworld in his entry in the now-discontinued Encyclopedia, an entry that is also present in the Encyclopedia's replacement, the Databank. Manaan's status as a planet and homeworld of the Selkath species was restored by its entry in the Databank.
