This is the first time we had anything on what a worldline is and I'm still confused. So "worldlines" is meant to mean other timelines?Ephemer: We are in the real world's Daybreak Town. It was copied into the data world before the Keyblade War, along with various other worlds that were converted to data. The real world was destroyed due to the Keyblade War, and the worlds scattered. They're still connected in the data worldline, which is how we're able to visit them.
