Marker Ring
these heraldric rings were developed for the lords and ladies of the noble house of the planet Kilia IV. Externally, the rings bore the crest or seal of the noble house. Internally, there were tiny communications systems that allowed members of the same house to recognize each other. When two rings from the same house were in close proximity, they began to glow, a tell-tale sign of the other noble's presence. Kilian Rangers had theur rank etched into their marker rings, a further indication of their social status.
