The map of the Reach
The whole continent, from the salt ports in the south to the Wall in the north.
I drew this map in 2016, three years before I wrote a word of the book. It has been redrawn eleven times since, mostly because a river was running the wrong way or a journey took nine days in chapter four and six days in chapter twenty.
The Reach is roughly the size of France. The Ashway runs nine hundred miles from the port of Saltmere to the foot of the Wall. On foot, with weather, that's about seven weeks. Every distance in the books comes from this map, so if Edda is somewhere too fast, write and tell me.
