According to roleplay the blood star constellation is only visible from Dwilight. So no you can't just pick it up and move it elsewhere.
That would be the easiest thing to deal with, really. The continent drowned, the shaking was so great even the Stars moved!
Culture is a product of its environment and this holds true in Battlemaster as well. It's been pointed out that the geography of Dwilight has created cultures that can't exist anywhere else. It's true that the geography of other game worlds also impacts the realms there, the difference is it evidently leaves them boring and stagnant.
This is an argument I buy. Dwilight has created a continental culture that does not exist in any other island. Pretty much everywhere else I play the realm border is a cultural event horizon. This is also fine, of course, but you couldn't transplant individual Dwilight realms elsewhere and expect the cultures to remain, because the cultures are intertwined.
