Rogue One: Catalyst
Described as a prequel to the events of the upcoming movie. Set in the early days of the classic trilogy, near the outset of the Galactic Civil War. Sounds awesome!
(I plan to ignore, or at most, borrow from Nate, the Wendig book at some point; just for completeness).
I have also been daydreaming about the Rogue One trailer since it was first posted. The spoken voice over near the end of the trailer, in particular, which appears to be directed at the central female protagonist, uncontrollable troublemaker and non-sanctioned rebel Jyn Erso:
What will you do when they catch you? What will you do if they break you? If you continue to fight...what will you become?
The end of the voice over coincides with a closing shot of our heroine (?) outfitted in distinctly Imperial gear, apparently somewhere deep inside an Imperial facility (air vent or access tube?).
Curious question: is the trouble-maker-turned-secret-agent still a good guy at that point? Probably, but it is a very interesting idea to ponder. She's dressed like I might expect an "Emperor's Hand" like Mara Jade to dress. Could just be her infiltration gear, but she might have gone...dare I say it...rogue!
