Prior to the mass extermination of the Quincy, hostilities sparked with the Soul Society regarding the destruction of Hollows. The Quincy, being Human, felt it was well within their rights to defend hearth and home against the corrupted spirits and completely eradicated them with their unique abilities. The Shinigami, however, saw the potential threats this method of destruction posed to the delicate cycle of reincarnation and made it their ambition to rectify what could grow into an apocalyptic calamity. The Quincy, being proud and distrusting of leaving their fates in the hands of the death agents elected to trust in their own hands and ignored the requests of the Soul Society to cease their methods; thus sparking what would grow into an inferno of conflict.
