Gruts that show great poise and leadership are recruited early to become fearsome Swog Riders. The Grut and Swog are bonded together and undergo years of training until they move, fight, and think as one savage beast. The Swog Riders are held in great esteem by other Gruts, especially the Arrow Gruts, and Swog Riders become leaders of these squads. Even one Swog Rider can instill acts of greatness in an otherwise average archer squad. When several Riders rally around the archers, the Arrow Gruts become capable of deadly attacks that become the stuff of legend.
