The Karthulian System is the training grounds of the original Paladins of Voltron filled with planets that have extreme natural environments to test each Paladin's skills as a pilot. It also appears to be the location of the Fripping Bulgogian, a restaurant favored as a hangout by the original Paladins of ten thousand years ago that has a table reserved for them, inscribed with their names and that of King Alfor. The Karthulian System is located in the quadrant overseen by the Mu, a family organization whose leader is currently Kythylian Mu.
