Love Oda for bringing back stuff from 100s of chapters ago. The 4 deities on Skypea were part of so many different theories and speculations over the past years, people wondered if Oda would ever bring that up again and here we are. Now anything is possible.
I wonder if the Florian Triangle Shadows will play any role in this as well. I mean, in terms of importance, it had narrators' boxes.
