When the Map Runs Out

There is a specific moment in certain journeys when the map stops being useful. Not because the map is wrong in the territory it covers, not because the cartography was poorly executed or the landmarks incorrectly placed, but because the journey has moved beyond the edge of the map entirely, into territory that the map did not anticipate and therefore did not chart, and the traveler is left holding a document that was genuinely helpful for everything that came before this moment and that has nothing to say about what comes next. The map has run out. The edge of the known has been reached. And what lies ahead is the unmapped, the uncharted, the territory that has no legend and no grid reference and no indication of what the terrain will require or how long the crossing will take or what, if anything, is on the other side.
