@secretsloth i havent gotten to play it because I don't have a Switch
But the idea started around when Legends Arceus were announced and it all clicked in my head perfectly.
The idea was to weave the present and past. While the modern region's lore would deal with the problems of today and cherish the multiple cultures, the past would be more chill, kinda like Breath of The Wild stuff.
I had an idea that after the lore of modern region comes to an end (typical woohoo i am the champion now etc.), the protagonist researches the history of region and gets to use a time machine crafted by one of the professors... which throws them back to ancient times and they need to make their way out of it.
Several characters I designed were supposed to have direct ancestors in the ancient version of the region.
There's much more to say, but I have no idea where to start and if you're still interested
