This is the war where the Gizerad - the leaders of the Gnomish Academy of magic took on the responsibility of controlling the spread of what they called 'wild' magic. Sorcerers were becoming more numerous in the world and each of them could unleash destruction on an epic scale and were without match.
The Council of the Chadori was created to maintain balance of the three magics, Arcane, Divine and Natural within the world. Many sorcerers did not wish to live in balance.
It was decided that the sorcerers would respect the balance or be made to resepect it for the common good.
The war lasted for over 70 years and resulted in the near elimination of Sorcerers amongst the four races.
