The Royal Cemetery Planet is an entire planet that was used to bury deceased members of royalty from various empires in the Delta Quadrant. It is rocky and barren, and barely able to sustain life. Any life on the planet is also exposed to radiation, ensuring the life on the planet was short-lived. Nevertheless, a species calling themselves Clansmen was able to form a fairly primitive society living on the planet.
The Royal Cemetery Planet appeared in an episode of the second season of Farscape.
