Endwalker is a new dawn in the expansion cycle as was A Realm Reborn in its time.
time for wild speculation thread
During A Realm Reborn the city of Ishgard sat on the horizon of the Coerthas like the morning sun, with the promise of the new days destination to come during Heavensward.
Now in Endwalker the new dawn, there is a new place with something sitting on the horizon like the morning sun
The hole of Etheirys sits on the horizon of Mare Lamentorum no mater the time of day, showing us a promise of the destination in the future expansion too.
One of the side stories dotted through shadowbringers was Limsa's move away from piracy to trade and maybe further exploration. sailing adventure here we come lol
