How do you recreate the realm on a different island without taking land from existing realms? Unsink BT?
Also how would the destruction be made "fair" so some realms don't get protected by others?
I think this would be a good argument for bringing back some of the regions of Beluaterra, though not necessarily all of them. That would save the devs a lot of headaches with coding in my opinion, although that would be up to them.
