First, we're starting to accrete a worrying number of German terms. Our recent envoy to Victoria was "Die Kaiser-Beuftragte". Our military uses a bunch of words like "Zerstörergeschwader Gruppen" and so on. I don't blame Ardashir for making that sort of thing up, but I'd be disappointed if people started mistaking us for Holzborg or another one of the Germany-clones.
Second, Ashkenatza has these nifty Hebrew signatures, like so:
The use of the Hebrew there, and of the Yiddish in a lot of other places, makes Ashkenatza seem a bit realer and deeper.
Shireroth used to use the Yardistani language a lot - not officially, but sometimes people would just say stuff in it. From a brief look, I'd guess it's the language some of the weirder-sounding city names in MASS - like Negrixnaht - are in. Here's a paragraph of Yardistani:
Likewise, dStryker's del-al'Enetet got used for a few things in the very early days - probably its most lasting phrase is "Ly'Technomaezj", which is "the technomage" in that language.Iardîstato ne basaj primís nja Vokablulari ce Gramatikr Spanjâtix, ye ljona Habašavegr cOrþaši ne basaj maís nja Idiômrsa Jermanix.

If Shireroth were to take one of these languages and run with it, then we wouldn't have to get everyone to learn it or anything, but we could make nifty official seals in the language, add it to graphics for greater authenticity, and name things like military battle groups in it if we wanted. Kind of the same way Babkha used Persian and Hyperborea uses Hyperborean - very, very sparingly.
Bill3000's latest obsession is conlanging, and like everything he obsesses about, he's gotten really good at it. He took a few little things I gave him and made it into a whole big Audente language that sounds like a cross between classical Greek and Sanskrit - technically impressive even if something of a mouthful. If we asked him, we could probably get him to expand on d'Enetet or Yardistani, or even take some features from both, and make somethng uniquely Shirerithian that could represent the language as it's spoken in Shirekeep and by government officials.
