Vetch’s younger sister Yarrow is a girl of 14. Though she is young, she is brave, precocious, and whip-smart. She has faith in Ged and Vetch’s ability to conquer anything together, and she wholeheartedly supports their journey together to the ends of the earth. Yarrow’s true name, Vetch reveals to Ged, is Kest—the word, in the Old Speech, for “minnow.” Like a wily minnow, Yarrow is quick, darting, and capable.
