Founded some time prior to CY 9781 the Majorum were members of the Nietzschean Alliance and fought against the Commonwealth. Little is known about it's current status or whether the Majorum have survived the Fall of the systems Commonwealth and the Long Night more or less intact.
Very little is known about the pride itself but based on Gaheris Rhade's personal beliefs it appears that the Majorum have a very idealistic concept of Nietzschean perfection. Rhade's exact words were "Our people were meant to be living gods, warrior-poets who roamed the stars bringing civilization, not cowards and bullies who prey on the weak and kill each other for sport. I never imagined they'd prove themselves so inferior." ("The Unconquerable Man")
Apparently, during the Commonwealth's fall, most members of the Majorum ended up on the planet Tarazed, the isolated Commonwealth outpost created by Sara Riley at the beginning of The Long Night ("Home Fires"). Under the Commonwealth influence there, members of the pride became loyal to Commonwealth ideals and principles. During and after Dylan Hunt's diplomacy to restore the Commonwealth, the Majorum became dependable, trustworthy citizens of the New Commonwealth.
It is entirely unknown whether the Majorum were prominent members of the Nietzschean community or the galaxy at large and to date the only known members of the pride are Gaheris and Telemachus Rhade.
