Despite Endwalker being the first expansion I actually finished the main story for in good time, the arrival of the Island Sanctuary initially distracted me from the patch story and then I got busy with school.
It's really, really good, though: starting with a treasure hunt and leading to a rescue mission for Vrtra's brood-sister (Azdaja), which of course leads to a bigger conflict with the Voidsent of the World of Darkness/Thirteenth.
