the Law of Averages
Large groups of mages are drawn to settle in a city when a so-called “Great Mystery” is noticed – an unexplained supernatural occurrence either over a long time from or large area. In Milwaukee, this mystery is commonly referred to as “the Law of Averages”.
As far as Great Mysteries are concerned, Milwaukee’s mystery is pretty abstract and difficult to study – and it’s only attracted a handful of rather academic Mysterium investigators since it was noticed in the 1960s.
From what has been discovered, numerous events in the city are linked to statistical trends; most of these are still being discovered, but a few are known: there’s exactly the average number of births and deaths (nationally), and the number of mages always remains the same.
