If and when you can be bothered, I have even more requests. And thanks again!
For the Fronc Reaches, a banner with the FR flag in the middle, and on either side of it: "We are a Free People" and "We Intend to Stay that Way"
And a banner for the Calderon Protectorate. As far as I can tell, it's the same symbol as the Taurian Concordat, but with the gold stars replaced by black stars. Maybe just something in your classical style, with the text "The Soul of the Taurian People". I can't think of anything particularly good though, that doesn't come off as too cheesey. Maybe It's better reserved for a signature bar rather than a full on banner unless there's a good idea for text.
