Aegis Knight Rings

Aegis Knight Rings are sets of rings, one 'Guard' ring, and at least one 'Ward' ring, usually four. When one of the wearers of a ward ring is harmed within 500 ft., the owner of the guard ring is informed of the danger, and who the ring wearer is. For each extra ward ring connected past the first two, the range is reduced by 50 ft, to a minimum of 200 ft. (at three ward rings, the range would be 450 ft.)

Significance
Aegis Knights Rings are issued to all members of The Aegis Knights, they are used as a form of identification.
