[@Mistiel]Mercurial's got it. When I started thinking up ideas for a Myrmidon I looked through the different countries, but none of them had a Japanese/Far East kind of "Fantasy Counterpart Culture." So when I wrote Gorou's backstory I just winged it and put in some stuff about Estala having a small subset of that culture before the kingdom as it is presently known was founded. Based on what's been said about the Estali royal line and such, this would have been hundreds of years ago, so they're still "Estalan" instead of "foreign," they just have somewhat unique traditions.
