Bo Derkins is one of several children of Mrs. Derkins, who lives in Briala.
In Chapter One, Mrs. Derkins believes that Aren Cordelaine's younger brother is a bad influence on Bo, although Bo is the older of the two. She blames Aren's brother for coercing Bo to break into the wine cellar. Aren's father has a different viewpoint on the matter.
In Chapter Two, Bo and Aren's brother have again gotten into the wine. No information on the Derkins family is available in subsequent chapters.
