His legacy secured, the twins and their future empire are left in the care of Alia. Part Two: The Children Paul's and Chani's children Leto II and Ghanima are now young adults; Princess Irulan has protected their interests as her own. Now married to Duncan, Alia is still regent of Paul's empire and official guardian of the children. Irulan's sister Wensicia yearns for a return to power through her son, Farad'n.
