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.
I'm not going to argue which continent needs to go, but if you can roleplay that a bunch of pretend stars in a pretend sky can have pretend effects on people then those same pretend stars can probably suddenly move without much effort in anyone's roleplays. The stars are divine, after all. Who are you to say they can't move?
I do buy the argument that the culture is a product of the geography, but any established culture can endure elsewhere too because it has been established already. I moved an entire religion between continents myself before. It wasnt the same size, influence, or anything at all like SA, but it adapted and worked for a long time. Other religions exist between continents just fine currently too.
