Willow-21

She uses a week. I mean, we know that Edelgard and Hubert have access to various warp technology when she's acting as the Flame Emperor (traveling to Remire village, etc. in the middle of a mission) so that probably reduces travel time when they're involved. I would say that there could be a network of warp pads, except that the students don't seem to recognize them in the underground chamber mission when they're rescuing Flayn. That said, we do know that a person using the Warp spell can transport both the target and any battalion equipped to them, so that may actually be a possibility for getting people through difficult terrain.

So this took a hot minute. I took the statement by the creators to do some calculations about area and distances (drew a circle approximately the same area as the map, calculated the diameter based on the stated area of 2/3rds the size of Europe, and then transferred that diameter into distance across the continent) and came up with a roughly to-scale map of Fodlan for distance and travel calculations. Who doesn't like to do math for fun? The actual calculations led to a scale of 1in. = 500km rather than 300km, but that would mean a 30 day journey from Garreg Mach to Fort Merceus. So I made it 40% smaller. It's a wonder we're able to get anywhere at all. Based on the fact that thru-hikers typically travel 10 mi (16km) a day, each small box (1/10in) is equal to approximately 2 days of travel on foot or 1 day of travel on walking horseback. (I also fiddled with the rivers to make them geographically probable.) I'm also including a version with the approximate locations of different settlements and landmarks. I will update as I add more details and refine the project.
