War of Northern Aggression
The War of Northern Aggression was a war instigated by radical Oarfanists (see: Oarfanism) against all countries who harbored followers of non-Oarfanist religions. It was sparked with the Vailic Ultimatum, which demanded the so-called "heretic" states to convert to Oarfanism and hand over their heretical citizens, as well as bring forth certain political enemies for prosecution.
