I have tracked the various fragments of the staff across this world and in doing so, discovered Kel'Thuzad's plans to reform the staff. He has already collected several of the staff's fragments - which are being held by his most trusted lieutenants.$B$BI cannot emphasize enough the importance of keeping the greatstaff of the Guardian out of Kel'Thuzad's grasp. Frankly, I do not know what the result would be, other than a catastrophe of epic proportion.
