Spacing Guild
Awakening, Paul launches an attack on the Harkonnen and Imperial troops with his Fremen army (and with his personal bodyguard, the Fedaykin), riding the enormous sandworms indigenous to the planet. In the attack, he learns that his son Leto has been killed in a Sardaukar raid. They win and Paul requests an audience with Shaddam IV. He threatens to destroy the spice melange, thus making transport between the planets impossible and effectively destroying civilization. In return for preserving the spice, he requires the hand of the Emperor's daughter, the Bene Gesserit-trained Princess Irulan as well as the Emperor's abdication in favor of Paul. Urged by the Spacing Guild, Shaddam accepts his terms.
