It has been settled by humans, Ghayrogs, Skandars, Vroons, Liimen, Hjorts and other alien races for many thousands of years.
The aboriginal inhabitants of the planet, the Piurivar, were conquered by humans many thousands of years ago and are now confined to a reservation.
The planet is ruled by an unusual tetrarchy of Powers: an adoptive Coronal rules in a highly visible and symbolic manner from his palace atop Castle Mount; the previous Coronal retires to become the Pontifex, the head of the bureaucracy in an underground Labyrinth; the Coronal's mother becomes the Lady of the Isle of Sleep, promoting the morals of Majipoor by sending dreams to its inhabitants; while a hereditary King of Dreams on the distant continent of Suvrael punishes wrongdoers by visiting them with nightmares.
Majipoor receives the occasional starship, but is generally considered a backwater planet.
The average Majipooran lives a peasant lifestyle, and agriculture is a common occupation.
