Kurmas's Banner

Overview
Kurmas's Banner is a legendary artifact which would completely negate the powers of the enemies of the wielder. It was used with great effect by the Orkedric, but was later destroyed during a power struggle. There are rumors that pieces of the destroyed banner have the same, if lessened, power, however this has not been confirmed.

Uses

 * Any enemy of the wielder who comes within 25 miles of it will have all magic-based powers erased until they leave the radius.
 * Did not naturally decay, but could be destroyed. (spoiler alert! It was)

History
Kurmas's Banner has said to have originated in Sylarritoh, forged and sewn by the greatest wizards and tailors. It was carried into battle, and as many of the other race's powers are magical and come from tiers, this became a superweapon that caused the defeat of anyone the Orkedra came into contact with. During the civil war that ravaged the Orkedric empire, the banner was destroyed by a disgruntled soldier.

Aquiring
If all the pieces are put back together it is theoritaclly possible to reforge it.
