A male aryx, Kweex was the leader of the flock on Hapylo Isle. He was the mate of Pyrnu and personal mount of Wiil-Hur-Krein. Kweex was distraught when he discovered his mate slain by a nexu, but his rider managed to soothe him and taks him with assembling the flock to kill the nexu and serve as mounts for the Gruesome Gackles.
