Soooooo our main force-using badguy is Kylo Ren? Who, as stated by Abrams, is NOT a Sith, but a "Knight of Ren", with Kylo Ren not a real name but more like some kind of title or so? Right? And Kylo seems to be interested in age-old relics of the force?
Now when we saw Kylo the first time every advanced Star-Wars-Fan had the same thought: Revan...
Re-van ... mumble this through a head-covering mask and add a couple of thousand years plus things/changes like Korriban/Morriband ... you might very well get
RVN ...yeah...oh...hmmm...... or R E N ?
Wouldn't it be cool if Kylo expositions how the Knights of Ren are based upon an age-old Force-User that embraced both light and dark and carved his own way within the Force etc? Something like that?
Not that I needed something like this, Revan more or less lost me as a fan after gender-changing her into a canonic male but still, I kinda like this idea, though yeah, its a stretch and probably ... but damn, Kylo's outfit just screams for this...and a revelation like this would more or less save teh Old republic Universe. One can dream, not?
