I think that all of fairytale land, meaning the original reality where everyone was living, the Enchanted Forest, were transferred to Storybrooke. The Enchanted Forest doesn’t seem to be that big of a place because travel doesn’t seem to take too long for the characters.
PS. I mean i think that the actual people were pulled in from all of the Enchanted Forest not the actual land. I don’t think that the land is like crushed under Storybrooke. I know some people think that.
