Beginning in 1040 AA and lasting until 1053 AA, the Aldresian Crusade, named after the young squire Aldresia who led it, was waged against the lich Canrec the Defiler and his White Pestilence. This crusade saw the sacrifice of Aldresia to kill Canrec and a cure made for the Pestilence.
This crusade took place primarily within Corvuria as the White Pestilence resulted in hordes of zombies flooding the land. Many of the participants were Roilsardi knights and commoners who fled Lorentish rule to achieve glory and lands following Aldresia against the undead. Many of these Roilsardi did in fact find land to call their own within Corvuria among the rubble and uninhabited land left in the undead's wake after Canrec was slain. One such family, the Sil Vivin, cemented their power during this crusade and kept charge of Corvuria. Since then, they have become one of the most prominent Cannorian families, controlling the Vivin Empire.
