Dyzzleberry Dictionary ::

A form of martial arts popular on Planet Authair. Kan-du is performed exclusively by Authairian males who are trained to use their claw as the weapon of defense only in the event of threat to life. Kurl Tszargon, Ponce Heidon, and Gore Andriol are kan-du masters. With Kurl’s reputation—as the grand master of kan-du, not to mention his astronomical expertise—Dorf suspected Cimi would spout out Kurl’s many awards. (3)
