Formerly these six men were part of The Order of Commenor, otherwise known as the Commenori Knights of the Systems Alliance originally established by the Jedi Master and King, Veiere Arenais before his descent into the Darkside of the Force.
Found within the Ilaria woodlands of Commenor itself, Veiere had full access to the Force Enclave for which he had built years prior to his recruiting the Soverign-Guard; they already trained within the force through a neutral learning stratagem which reflected the very governments stance of nuetrality across the Galaxy, these six individuals had previously committed themselves to serving the balance in all things living, their oaths to Commenor were meant to stand the tides of aggression that they might fight to protect a place of sanctuary and a sovereign guardianship over those wounded and rendered homeless by the outside conflicts occurring and being waged across the far reaches of known space.
Through his personal ambitions however, fueled by his own grief and discouragement over the failures of his past and those within the Jedi Order he had for so long stood to represent and attempt to uphold in their ideologies, Veiere Arenais made a quiet return to the Order of Commenor following the attack of the Iron Knights, they whom had formerly introduced the students of the force on Commenor to a grim and brutal succession of violent attacks slaughtering many of the young. Harnessing the anguish in the wake of this tragedy, Veiere convinced half a dozen of them to follow him over to the Dark Jedi Temple of the world of Rannon where he would then continue to train them, to guide them ever close towards the lure of the Darkside while his own dark powers grew stronger with each passing day; the result of their training has now placed them at the height of the Dark Jedi Order where they reside behind the Dark Jedi Master as his entourage, his Inquisition and sovereign-Guard.
