I'd say this is still something I'd kinda-sorta like to see them touch on at some point in the future.

All that build-up, just to reveal Zodiark was essentially just a husk for Fandaniel to possess, just really wasn't a terribly satisfying "twist". I loved the Fandanial arc, don't get me wrong, but where Fandaniel and Ilidibus both had their chapters closed in a meaningful way, it just never felt like we got to really experience *Zodiark*, in the same way we got to experience Hydaelyn through Venat.
