The first chapters tell of the generations which came prior to Sigurd, beginning with Sigi, a man banished from his homeland for murdering his neighbor's thrall. After much adventuring, Sigi settles down to rule over the Huns. His wife's brothers eventually become envious of Sigi's power and wealth and raise an army against him. In the ensuing battle, Sigi is killed and his in-laws take over the kingdom. Sigi's son Rerir then avenges his father's death, killing his uncles and regaining his father's throne. After many years, Rerir becomes ill and dies, and shortly thereafter his wife gives birth to their son, Volsung. Volsung grows up and marries Hljod, the daughter of a giant. Volsung and Hljod have eleven children, the two eldest being the boy and girl twins Sigmund and Signy.
