@Arkandel You could have the mage be the mayor or something, and the Mage knows all the players thanks to a crystal ball or some other McGuffin. When the mayor sez jump, yous jump, capiche?
You could have said Mage/Mayor be as reasonable as needed, but that could be an in universe reasoning behind depowering individuals who get on the mage's shitlist.
Of course, I'm not up to speed on WOD, but I frequently hear complaints about how powerful mages are, you could also go with some sort of godling/demon/alpha complex super computer if you wanted.
