>>48468323Hisui isn't Sinnoh though, even the map they gave out is markedly different to Sinnoh's geography.
All I'm saying is there's two sets of starters, one in-region (where most regional pokémon end up getting their adaptations from, living in-region to adapt) and one brought fresh off the boat to the lands. That they just said "starter evolutions" opens up the possibility it's not actually the three given out, but the three wild beasts.
