So, I wanted to make a character best-described as a “pseudo-German” (that is to say, from a fictional country in a fictional world that’s obviously a reference to old Germany).
Enter an eccentric early-20th century language inventor called Elias Molee. Molee was both strange (his disdain of capital letters, more than a century onward brings up Undertale references to me), and his dream of unified Germanic peoples is understandably creepy in light of later events.
Molee’s life project was a pan-Germanic conlang he called (with various spellings) Teutonish. So I took one version of Teutonish (whose public domain text can be found here) and I was set. Now that character has a “real” native language.
