Hmmm. I wonder how the Devs are going to pull this off....
Hm... it's more of a scripted thing...
Like you hit a trigger that checks to see if you have it, and if you do, it'll show you some cutscene elsewhere and reveal things to you that you might not otherwise know. It's more of a story related force power, like force persuasion is. At least, that's my current understanding of it. Though again, I didn't implement the force powers.

Sounds like something Jolee and Juhani had when they insisted on joining you at thee Rakatan temple.
