It's all just fantastic religions and their dogmas. Other than the Force existing and having something of a feedback loop with ones emotions and intent, nothing's for certain. The Jedi, the Sith, the Nightsisters, the Sorcerers of Tund, the Aing-Tii, etc, etc... all just blind men trying to describe the elephant.
Absolutely! My concern though is the OP is apparently trying to give bonuses based on just being a follower of one of those religions/dogma's/organizations.
You mean just like Jedi and Sith get bonuses in the game? Are you even familiar with the Je'daii Order? To go from Journeymen to Ranger, a Je'daii Journeyman must make a journey across the surface of Tython and visit all Nine Great Temples. It's far more dangerous than what a Jedi or a Sith needs to do to go from Padawan to Knight. Considering the fact that Tython is in the Deep Core, it takes a special breed of person to break into the heart of the Empire to find a planet long forgotten. Let's also not forget that the planet Tython is unforgiving itself and anyone that is not balanced within the Force is subjected to Force Storms that will kill the individual. So yes, I attached bonuses to the Je'daii because they face a far greater danger than a Jedi in the time of the Empire.
