And that’s a problem… because?
There’s nothing to say that Nelves aren’t still living everywhere else.
It’s fine that there’s Nelves going to move/live in Amirdrassil, doesn’t mean all Nelves are doing that.
Doesn’t mean it’s a massive overarching “”“homeland”“” to the Nelves.
Having their ‘center of civilization’ on the Dragon Isles doesn’t really mean anything.
It’s just a home to the people who will eventually live there.
