Actually, Ithilion, that's a not-always-agreed-upon fact. Some consider his fully fleshed legendariums to be higher canon. And I would take it as a whole, but that would be adding in content as well as removing content. Their Sun and Moon have different underlying mechanics than ours, and some of the mechanics of our sun clearly not shared by their Sun cause Aurorae. Unless some alternative method of creating Aurorae is in place, they would not exist.
