All of those problems apply pretty much equally to any island. They're not unique to Dwilight.
Same for every island.
Same for Coralynth or Obisidian Islands, etc.
That will pretty much happen with any islands that will close, and it will be a major headache to organize. But, judging by what Tom said yesterday, it'll be up to internal discussion in the migrating realms to decide on a target island that suits as many people as possible.
While the geographical uniqueness applies to Coralynth or OI, I have listed reasons above showing it applies to most of the island and I can likely find even more reasons why Dwilight's unique geography is a huge part of what makes the continent unique. And the character restriction is a bigger problem with Dwilight because there are more players there than any island making it harder to work as there are a lot of players on Dwi.
