This is Captain Jonathan Seabourne, editor of Wanderlust magazine with an open letter to the various astro/stellar/celestial cartography groups of Sirius and any other academics who wish to chime in. Recently, our magazine has used "Sirus" and "Sirian" to refer to residents of the four "original" houses (Liberty, Rheinland, Kusari, and Bretonia). But as we expand our influence into Gallia, my understanding is that from an astronomy standpoint, Gallia technically occupies its own unique sector. So if our magazine wishes to refer to the settlements of humanity overall, what name/adjective should we be using that is most inclusive?
