Star Wars: The Force Awakens - 10 Things We Need To See In The Next Trailer
5. The Knights Of Ren
OMG, Kylo Ren isn't a Sith! That was some of the reaction to the reveal by J.J. Abrams, but really it was kind of obvious (the lack of the word 'Darth' was a pretty big clue). Much more intriuging was that he belongs instead to a group called 'The Knights of Ren'.
Not much is known about them, and hopefully it will stay that way until the film, but they seem to be some sort of cult that has grown out of Darth Vader's death, with a worship for the Sith Lord (note the amazing/creepy shot of his helmet in the teaser).
While it doesn't need to spoil what they do, it would be awesome to see a brief shot of them as a group. A bunch of black hooded figures, standing, then a shot of that broadsaber. It establishes the group, but in a way that only builds excitement for them.
