Luke Skywalker. Fluke Skysquawker is a devoted practitioner of the Schwartz and a celebrated swordsman. Although he is a Human, he was brought up on Jupiter’s moon Europa after both his parents, Arkan and Shmappé, were killed by Bath Avoider. Fluke first discovered his skill with the Schwartz when he killed space pirates in his sleep. Later he met the hermit Lone Starr, who trained him like his mentor, Yogurt, had.
