Manaan

Manaan is an ocean-covered planet that is home to the bipedaled anphibious Selkath. To handle business with offworlders such as Humans, the Selkath built Ahto City, a giant city floating above water, it says that most of the Selkath cities are under the water and that outsiders would never see them. Manaan also is the only planet where the healing product, Kolto is grown. Kolto is similar to Bacta which is harvested on the planet Thyferra.
