Venture Though Tamriel
The Staff of Chaos
The Staff of Chaos is an ancient relic of untold power. The staff, also called Balac-thurm, was created by Loreth, a pupil of the hermetic enchanter Dalak. Loreth created the staff, sometime after 1E 480, based on his own findings and skills. Having been forged from the essence of the very Land itself, it is nigh-indestructible. It has the power to open gateways into other worlds and is capable of obliterating the entire corporeal form of a living creature.
In 3E 389, the Imperial Battlemage to Uriel Septim VII, Jagar Tharn, who had stolen the staff from beneath the city of Mournhold, used it to imprison the Emperor in the realm of Oblivion. He then used it to destroy his apprentice, Ria Silmane in order to prevent the Elder Council from learning of his betrayal.
To solidify his grasp over Tamriel and ensure nobody had a chance to rescue the true Emperor, Tharn knew he had to dispose of the staff. Unable to destroy it, he did the next best thing, splitting it into eight fragments and hiding each piece within the most forgotten and dangerous places throughout the provinces.
