How much time before DPP time? I mean, if Sinnoans are settlibg at this time and already have access to Alola and Unova mons, so it means the settlings in those places happens before Sinnoan settlings. Alolan settlings happens when there was already people in Kanto, since Kantonians settled in Alola too.

Colonization timeline:
>Johto and Kanto have human pop
>Mass immigration from Kanto and Johto to Alola
>Johto, Kanto, Alola, Unova have human pop
>Mass immigration from Unova, Johto and Alola to Sinnoh
>Alola, Kanto, Sinnoh, Johto, Alola and Unova have human pop
Missing data: Kalos and Hoenn
Fact: Kalos already had people living there with a complete civilizations, kingdoms and shit 2000 years before the XY events
XY events happens at the same time with Hoenn (ORAS) events

How much time before DPP time is Legends going to be? It's weird to think that a Hokkaido inspired region would be first colonized after Unova and Alola
