Aegis of Aggramar

The Aegis of Aggramar is a titanic weapon and one of the five Pillars of Creation. Eons ago, it was used by the Titan Pantheon to defend planet Azeroth's world soul. It is presently under the possession of the Kirin Tor and placed atop the pinnacle of the Cathedral of Night, being one of the five relics capable of closing of the Tomb of Sargeras, the Burning Legion's foothold into Azeroth in the present day. When used, it is capable of fielding a near-unbreakable shield to deflect mundane and magical attacks.

History
The history of the Aegis is not fully uncovered, but it is known that the Titan Pantheon used the weapon to defend the Azeroth world soul from madness and corruption, such as the threat of the Old Gods. It later became in possession of the titan watcher of Stormheim and ruler of the Halls of Valor, Odyn. Odyn later gifted it to members to the fighters of the class Order Halls for their displays of valor and honor, and it proceeded to be used to defeat the God-King Skovald. Later, it was given to the Kirin Tor for use against the Burning Legion, and is currently placed atop the spire of the Cathedral of Night in the Tomb of Sargeras.
