It doesn't. But true north doesn't move, and it's right at the top of
standard maps.

Except that apparently true north DOES move. The tsunami/earthquake of
a year and a half ago reportedly caused the north pole to shift about
an inch as well as decreasing the length of a day. Just goes to show,
you can't depend on anything.
