Many forces sought control of the Atreides twins and, when the death of Leto was
announced, this movement of plot and counterplot was amplified. Note the
relative motivations: the Sisterhood feared Alia, an adult Abomination, but
still wanted those genetic characteristics carried by the Atreides. The Church
hierarchy of Auqaf and Hajj saw only the power implicit in control of Muad'Dib's
heir. CHOAM wanted a doorway to the wealth of Dune. Farad'n and his Sardaukar
sought a return to glory for House Corrino. The Spacing Guild feared the
equation Arrakis ' melange; without the spice they could not navigate. Jessica
wished to repair what her disobedience to the Bene Gesserit had created. Few
thought to ask the twins what their plans might be, until it was too late.
