The End of Dune In Fretag's Triangle form

In the exposition the main characters are the family of Duke Leto. They begin the story on a planet a lot like earth with open water and lush green plants. They are in the process of moving to the planet the story takes place on a dessert world with nothing but a rare spice that is like a drug to the rest of the universe. This is what makes the conflict. The Rising Action comes when the enemies of the main characters invade the dessert world to take it back. They kill the duke and most of his men by using a trader. The trader was bribed with the chance of seeing his wife but she was already dead. The duke’s 15 year old son and the mother of the boy escape into the dessert. They are chased into a giant sand storm and are presumed dead. They escape however and join up with the dessert people known as freeman. The Freeman except them into there society and hope the two are the fulfillers of a prophecy. Both of the two survives have powers of premonition and have been trained to use there powers so it is easy for them to assume this roll. The climax is a ceremony were the mother becomes head prestos of the dessert people by tripping on this dangerous drug that she has to transform (with her mind) into a form of the drug safe enough for the rest of the tribe to trip on. She didn’t mention the fact that she was pregnant with the Dukes daughter. The undeveloped girl is exposed to everything her mother ever learned along with the old prestos who is giving the test. Then there is this big orgy of about 200,000 people but the author doesn't really talk about it, it is just casually mentioned. That is the beginning of the Falling Action. Then we are pushed forward two years in the story. The Enemies of the Duke are still just as treacherous. They are concluding the training of the next generations. The son of the Duke Paul has become a prophet of the dessert people and has versions of concurring the universe with his dessert tribe of worriers. He doesn't what the vision to become a reality but decides that it will happen weather he is there to lead it or not. There enemies come to the dessert world to try and stop the uprising and kill its leader. They enter into battle one that costs Paul his infant son. At the end of the battle Paul the Duke's son has a knife fight with the last member of his father's enemies family.
Paul then marries the princess of the emperor (his new enemy) in order to restore peace but promises to the mother of his son that he will never touch or show a soft glance at the woman and that he will not allow her to have any of his children. There is no real resolution except the end of the conflict for now, because this is the first book in a series.
