The Anti-magic Shield surrounds the Imperial Palace, and a large portion of the Empire City. It covers all the city except for the Empire Arena and the Empire Slums. It appears as a blue force field-like barrier. When the Overlord enters the city, Emperor Solarius is behind the shield. It basically prevents the use of any magic within its perimeter, and is powered by the large vat of magic in the Magic Containment Room. It also appears to harm magical beings, since after the sentinels activate it, it greatly injures the Overlord and he is made helpless, ready to be thrown into the Empire Arena.
