We've done time skips before but a total of nine months being written about in these field notes as a 'this is what happens' is a long time. Not least of all because of Endwalker where we're given to believe the whole world is suffering from the End Days so the 4th Legion and Gabranth just ya know... chilling with it and still fighting Dalmasca during is just so out of place with the rest of the narrative.
