Political event
A combined effort of all the Council Collegiums, the lich was deposed and destroyed, ending over a century of tyrannical rule. In its wake, the city-states decided to form a federation, which would be ruled by a council of all the Grand Magici. This would be the Arcanonic Conclave. The schools and city-states would still remain independently ruled, but the Arcanonic Conclave would be able to govern each other and ensure that no one would be able to take control of all schools again. They would ensure that all schools would work towards the same and unifying ideal of magical advancement.
