Forgot some lore elements from ARR and Heavensward and what's the shape of the world?

[Cilia]

-After leaving the hospital, Estinien brought flowers to Azys Lla in memorial of Ysayle. He has since been traveling the world working as a mercenary in addition to helping the Alliance win the war for Ala Mhigo from afar. (He shows up again during the DRG 60 - 70 questline.)

-Shinryu and Omega both first appeared during the climax of 3.55. Shinryu was indeed the primal Papalymo bound.

-Nero disappeared from the narrative following the Crystal Tower and first reappeared during 3.4's closing scenes, seemingly having found Omega on the Cartenau Flats. (How he got there is a huge mystery.) Where he was and what he was doing in the interim is unknown; he describes himself as a "free agent."

-Hydaelyn is supposedly round like most planets; we see it from space during King Thordan's Ultimate End. As to why the Far East doesn't run on a different timezone... ¯\_(ツ)_/¯

-Nero got out of the World of Darkness at the last second thanks to Cid literally lending him a hand.

-The Cartenau Flats are between Thanalan and Mor Dhona.

Amusingly, this would be unusual in the history of Final Fantasy, being that most of the world maps in previous games would fit with a torus; you go off the north edge and reappear in the south, which doesn't work with a globe.
