[@Queen Raidne]If we are at it, how do you feel with slightly fantasy WW2 nations?
I always wished to test my elves from Yllendthyr in an actual WW2 scene.
1941 where they fit just fine.
Aside from being elves the only "magical" elements are Mithril (basically the mix of the properties of Aluminium and Titanium and replaces steel products for Yllendthyr as a whole) and Kavuria (which may not be a concern because I got that via trade with Avalia so I'd need to resort to hydrogen and helium instead).
There's no magic involved whatsoever, just a race which developed differently and material which could be plausible (Mithril is actually worse than most steel alloys)
