The inhabitants of Planet Fleed were descended from a group on Earth that was originally part of the empire Sygma. For years they fought another group that eventually went into space and settled on a distant planet that was named Fleed. Generations later, the inhabitants forgot their origins and lived a rather peaceful life until the planet was attacked by the Vegan Empire.
Planet Fleed was ruled by a monarchy with the royal family in charge with assistance from ministers. The usual clothing on Fleed compared to its original counterpart were togas. While Planet Fleed has not entered war in centuries, it keeps many high tech weapons such as Grendizer.
