|List of all locations|
Plun-Darr is the home planet of the Mutants. It is located in a far away distant galaxy. Not much is known about the planet itself except that it is orbited by a number of moons. It is not known exactly how many moons orbit the planet but there are at least three.
Judging by the Mutants' technology and architecture on Third Earth, it is likely that Plun-Darr is a very swampy and dreary place. It most likely has a Castle Plun-Darr, similar to the one on Third Earth.
