The Green Rider brooches are gold and depict a winged horse. They were forged by a man named Isbemic during the Long War for Lil and her Riders. It seems all Riders are people with innate magic, albeit only humble abilities, that can only be tapped when coupled with a Rider brooch. The brooch also identifies one as a Green Rider, but only to other Green Riders. The brooch is invisible or distorted to look like a simple trinket to the eyes of anyone other than a fellow rider. The brooches were originally forged during the time of the First Rider, and since then have been passed down to new Riders. New Riders are able to pick through all the brooches and choose the one he or she most identifies with, or feels most drawn to.
