Another thing on rules or things, we should speak of.

In terms of communication, I would say, since not every state here was once a Pacifica-nation, Austral isn't a language spoken in space.
Of course the rp should be written in English and dialogues can be in English too, but I just wanted to mention that kind of a plothole would occur, if Englsih was spoken by a civilisation that never had any contact to English.

As for communication between the species:
Universal Translators (e.g. the ones the ANF is working on ) shouldn't (instantly) be able to really be universal.
I know it's FT and sci-fi, but still this tech would need data to learn languages and most likely won't get it through "just scanning other species" (at least not in the beginning). Please notice, that we even don't have a universal translator for earth yet, where the languages are most likely more similar to each other than the languages throughout space could be. Even the idea of a universal translator is sci-fi, since it's questionable, if tech can really learn languages and translate them in any other language possible properly. We don't have to be perfect civilisations with perfect science and tech in the beginning, right? ^^
