Tiercel's Trackers are a group of kestrels, expert trackers all, consisting of Tiercel, his mate Sapphira, their sons Isaac, Mycroft, and Alger, and their daughters Afra, Iria, Elea, Minaithe, and Aleria. They were somehwat of an offshoot of the Tracking Chaw.
It was founded during the War of the Six Kingdoms, when the Tracking Chaw simply was not enough to track down and kill the leaders of the New Legion, who at the time were in hiding. So, Tiercel, returning from retirement, taught his family the ways to be an expert tracker. Soon, they all were very critical in the defeat and overall surrender of the New Legion.
