I didn't have time to read what everyone put here. But it was already established back in the first and second season that the Dark Curse's effect can reach beyond jus one realm. The proof being Dr. Whale and Jefferson's presences in SB. Because their flashbacks showed their were in different realms instead of Enchanted Forest or Fairytale land. Unless now the show writers want to re-establish that they were actually in FTL or EF at the time, the Dark Curse definitely went beyond just the FTL. As for why people of Arendelle were never affected, it's likely because Regina didn't have any problem with them, so she didn't choose to include them in the curse.
