This item is a quest reward from The Mage Hunter.

Background

 * This greatstaff was wielded by Alodi, the first Guardian of Tirisfal. He bore the staff into many battles against Legion forces for the century in which he served as Guardian, then stepped down from the role of Guardian, but he retained the staff to his dying day. Upon his passing, the Kirin Tor stored the staff safely away for fear of what might happen if a lesser mage attempted to wield its power without the ability to control it fully.
