Jyn/Peter
"Not a problem, and alternate realities are super confusing, and I'd probably know less about them if it weren't part of my field of study, and the fact that I've had to deal with them a few too many times..."

"I think so. The Federation is a collective alliance of peace seeking planets and civilizations. There are other Empires out there, who sometimes war with the Federation, but not sure if any... Death Stars have been built."
He then frowned, "As for me, my planet is still divided into nations and fights like that are on a much smaller scale. There are empires as well, like the Kree and the Skrull, plus places like Asgard and what not. But they don't really fight Earth in general, as Earth isn't really... a 'whole unit' quite yet."
