War of the Immortal Mages
The War of the Immortal Mages began with a discovery. In 1768 BVD a cabal of arcane scholars found immortality through a magical ritual. According to claims, the ritual bound a mortal's soul to the body permanently, in a way never seen before and beyond comparison with lichdom or life-extending spells: those who underwent it could not die, whatever befell them. It was so powerful that ten master wizards had to perform it together.1
An age of immortal wizards
At first the world, like the wizards, was well pleased with the outcome. Freed from the fear of death, the wizards pursued research that served themselves and all people, and completed with ease rituals that were expected to do their casters immense harm, working miracles without paying the price. Many historians liken this period to the Age of Priest-Kings. The immortal wizards became rulers over their lands and subjects and trained students, and most of the Archon Academy supported them.1
The war
In time some of the wizards realised how great a price they had paid and how absolute power had corrupted them. They were no longer human. To reverse the ritual they needed everyone who had originally taken part in it, and a bloody, destructive war broke out among the wizards. Their arcane battles shattered mountains, dried up lakes and razed cities. At last the High Church and the imperial nobility, weary of the madness, supported the repentant wizards and brought the long war to an end.1
Legacy
The period was so devastating that fear of magic and mages still lingers throughout the land, and for that reason Emperor Valigard IV declared the edict widely known as The Sanction. The true end of the immortal wizards is still unknown, for the events have been concealed.1
By a decision made after the war, the Archon Academy was isolated and set on a massive floating landmass in the north-west of the Lands of Exile, hovering above the Great Western Sea.2
