However, a dreadlord who had infiltrated the order intervened, interrupting their efforts and triggering a violent magical explosion. The damaged staff’s power proved nearly uncontrollable. After several wielders tried and failed to use the staff safely, the elite magi of the Kirin Tor hid it away lest it unleash further deadly calamities.''
