Carosi XII was a planet in the Outer Rim Territories colonized by the Carosites in 200 BBY after the destruction of Carosi IV. It was best known as a center of healing and tourism, attracting numerous and diverse visitors due to its location along a prominent trade route. Because it was also one of the few worlds to openly support the Rebel Alliance, Carosi XII also served as a safe-haven for free-traders and Alliance and New Republic agents.
