Actaea

I was wondering. Which language is the international (Acteian) language? I was thinking of not reinventing the wheel and making it the American version of English, but this could cause some conflicts on a historical basis: "English with some differences" is the official language of Kittypink, plus English names were found among many players of football teams from different countries; I could attribute this to the fact that "international" names are popular in many countries (I myself was thinking of using English, because I got tired of Roman names and later Latin), but I wouldn't want to solve such a question on my own.
