The Staff of Magnus can be described as a "metaphysical battery of sorts" used by its creator, the god Magnus. Using it absorbs an enemy's health and magicka, and lessens the effect of spells cast on the user. While it shields its user from magical attacks, the staff will eventually abandon its owner before they upset the mystical balance it is sworn to protect by becoming too powerful.
In 2E 582, during the events of The Elder Scrolls Online, the staff was in the possession of the Aldmeri Dominion, having been stashed in Marbruk. However, the lich Naemon had the staff stolen, whereupon his shade took the staff to the location of the Heart of Valenwood, the Ayleid Ruin of Hectahame. Attempting to use the staff to corrupt the heart, the shade removed the ancient magical protections that had been previously placed upon the ruin. The Veiled Heritance hoped to turn Valenwood into a "Shadow Wood." Luckily for Valenwood, however, the Dominion eventually invaded the ruins, killing Naemon. The staff ultimately ended up in the hands of Queen Ayrenn.
By 4E 201 the staff was somewhere deep within the crypt of Labyrinthian. The Last Dragonborn was sent to the Labyrinthian by the College of Winterhold, where they killed the Dragon Priest Morokei and brought the staff back to the establishment. The Synod and Psijic Order were both involved in use of the staff at this point.
