One of my interests is Geology, it can be proven that at many times in Earth
history the magnetic field of the Earth has flipped. Therefore there were
times at which if compasses existed, they would have pointed the other way.
The magnetic properties of Qo'noS could be vastly different, meaning any
culture developing there would not be as "north" centric as we are. While we
have 360 degrees, why would anyone else have the same number? While we
conventionally zero this on due North, why would a culture with less interest
in "north" do the same?
