Worldbuilding
A border is rarely just a line. In fiction, the interesting bit is everything that happens before and after it: the checkpoint, the paperwork, the change in money, the way two people from the same town start speaking a little more carefully once they know they’re being observed.
That’s where the world actually shows its teeth. Not in the map, but in the small adjustments people make to avoid trouble.
If a border doesn’t change behaviour, it’s probably decoration.

Borders are often just admin until someone decides they’re political theatre. The more useful fiction detail is usually the paperwork, the waiting, the petty rules that make ordinary people nervous. That’s where character shows up. A customs desk can do more damage to a scene than a tank, if you let it.
