I was considering whether folks regard the Jedi Luke Skywalker trains to be "real" Jedi, or must they have a temple on Coruscant and go through a structured program supervised by a High Council to be "real" Jedi.
How do you regard Kyle Katarn - who's largely self-taught? What about those from unorthodox backgrounds such as Mara Jade (Skywalker)?
Do they have the moral authority or authenticity of say SaeSee Tiin or Kit Fisto?
What about EU Jedi from older eras like Ulic Qel Droma, pre-Sith War, or Odan-Urr?
Speaking of the older eras, how about the Sith?
1) There was space travel and intergalactic colonization, wars, and finally centralized government forming.
2) There were Force users, sort of like how the X-men evolved from mutants with abilities.
3) They were persecuted and hunted, and some organized a brotherhood, a fraternity, for training, and acceptable public service - the Jedi
4) Some Force-users rejected that and believed might-made-right. They fought in the original Schism.
5) The Dark Side users lost to the Jedi Order and were exiled since prisons couldn't hold them.
6) They went out into the Rim Worlds and conquered the Sith aliens. The Sith ruled by their strongest, and the Dark Siders quickly became their Lords, hence Dark Lords of the Sith.
7) They returned to the galaxy to conquer the Republic but destroyed themselves and the Sith civilization in the process. The Sith species became extinct from the wars.
8) Dark Siders that try to increase their personal power organized around the traditions and religion of the Sith. I think the original "new Sith" use the Sith culture as an excuse, but it's undeniably a good teaching tool. These were Dark Siders like Exar Kun.
9) The "new" Dark Lords of the Sith started repeated traditions of using battle droids and Mandalorians to conquer the Republic. Eventually, those who would call themselves Sith went into hiding and The Rule of Two was imposed (but not strictly followed) by Darth Bane and those who followed in his footsteps.
10) In Bane's tradition, 1000 years later, Darth Sidious achieved galactic conquest during the era that the 6 movies we have take place in.
11) There may have been no living successor to Darth Vader, the last Sith Lord to die in that era, but we know that at least 48 years after Vader's death, his own grandson Jacen Solo became Darth Caedus, and Darth Kraayt was out there somewhere, too - perhaps carrying on the tradition on his own, too.
12) The "newest Sith" were organized into a brotherhood of multiple Sith Lords once again, by Darth Kraayt - who presumed dead - has been replaced by Darth Wrylock.
The Jedi engage the Sith in fights to the death. I suppose the Jedi have determined them irredeemable, as Master Mace Windu wanted to forgoe Darth Sidious' trial and execute him on the spot in ROTS.
So how legit are the Jedi of different eras and how legit are the Sith?
