Ment Web

To maje across distance requires stable ment so the frequency of the ment vibration matches between the brain and the point of majing, so a majic command can travel cleanly. Any interference garbles the majic, like a cracking voice over a bad phone connection.

The solution to reaching distantly across a city is the ment web, a full network of ment lines buried underground, where they are insulated from the city's thoughts, which gradually wash away all majic effects above ground, and can induce Ment Stress Syndrome.
