Well, there is the CIS and they are a GREAT bunch of people, however, IC wise take heed in knowing that they welcome the Dark Side in-house as well.
Gerwald Lechner
and
Darth Metus
are fantastic people to talk to on this.
There is also the Galactic Alliance, a lot of great writers and people there as well. Take heed IC wise that their primary outlook in the New Jedi Order is very progressive and a lot of them focus on wars and taking the fight to the opposition.
Auteme
and
Aaran Tafo
are two great contacts in that regard.
There is also the Praxeum on Jakku. They are GREAT for teachers. Look for
Romi Jade
or
Coren Starchaser
there.
Then there is the Silver Jedi Concord, a very traditional Jedi Order. Not the best reputation at the moment IC wise.
Kiara Ayres and
Starlin Rand
are two great people to talk to there.
Ignore the moron with the Dwayne Johnson play by... he's an idiot...
...wait?
