After the Pluvial Pact, the covens of magicians spread accross the realm were forbidden to meddle in affairs of nations. Various enclaves were set aside for the sorcerer-kings of yore in order to maintain the fragile peace.
Innevitably, such tension would be violently released. The necromancer Svoskaloth,from the Isle of Jarldoms gathered together a group of wizards to inflitrate the societies of the north. In one horrid day, they seized control of the major nations of Aulormior, Eothnar, and the clans of the Isle of Jarldoms.
Over the course of 100 years, rebellion efforts and aid from the south allowed these tyrants to be defeated, but not without major loss of life. In the end, the death of Svoskaloth marked the end of the war.
