This is an interesting question, since we know that the Tyburs were the shadow rulers, but it seems Eren might have wiped them out (or at least killed Willy and took the tybur titan).

I doubt we'll go back to Marley again, since we're on the final arc and everyone and their mom are about to invade Paradis, so I'm guessing Paradis will be the final setting, which is fitting.
