An idyllic scene:
The beautiful woodlands stretch off into the distance in all directions, a small muddy cart-track meandering off towards the rest of civilisation.
A selection of... mostly-human individuals, sitting or crouching by a sparkling stream flanked with a profusion of bluebells, panning the water for something - not gold, something more precious than gold, something more magic...
All of them have some slightly non-human features - prominent green veins, or patches of bark, or vines and flowers growing amongst the hair, or thorns jutting awkwardly through the skin. All of them have at least one prominent tattoo, a variation on the theme of a twining thorned branch; some have many more.
A few children running here and there, not tattooed, fetching and carrying and dancing and playing. Some are a little green-veined, some with scabs of bark from inevitable childhood accidents.
In general, a peaceful and Prosperous place, if a little light on infrastructure and facilities; some wooden structures cling to the forest's edge above the brook, haphazard shelters built with love and energy and not very much in the way of skill and patience.
"Oh, you don't know about the language thing? That's where this theory came from - so, there are lots of different people on the continent and lots of them hate each other, and on other continents in the world people speak lots of different languages. But on this continent everyone speaks the same language even though that makes no sense. Like even the Tsark speak the same language and they live in a big isolated mountain fortress and never come out."
"Huh."
"She says that does seem like the sort of thing that your physics might arrange for, yes ma'am."
"It's not always been like that for language because the Gwyrn Morfa were a thing - I've probably mangled pronouncing that - they spoke a different language before the Terun basically wiped them out? I think it's, like, meant to be one of the things the Terun left behind, like they loved their language so much they did a big magic working to make everyone speak it, and that's outlasted them?"
"She says she's not sure how she'd differentiate that. She'll look into it, though, it might be possible to figure out."
"Like, I'm just thinking, maybe the Terun met someone who was using - electricity - and did magic to stop them. It'd be the kind of huge short-sighted nonsense they got up to."
"She says that's good to know, ma'am, and if it is that, she might be able to figure out how to undo the effect, eventually. It's not something she's seen before; Sith can't generally produce persistent effects like that."
