I've written about this over in the Edge of the Empire forum, but I thought I'd mention it here in case there are people who frequent this one but not that one. I have a blog dedicated to Edge of the Empire , but it has material that could be useful for an Age of Rebellion game, too. In particular, the most recent post details a Rebel outpost known as the Aerie.
