Frank Herbert’s intentional design of the “Dune” universe around its characters made his story conjure emotions of dread and painted a clear picture of a future riddled with politics and religious mind control.
Paul Atreides
Role: Paul Atreides is the main character in “Dune.”
Key Info: Paul is Leto, the Duke of the House Atreides’s son. He is skinny, as his rib cages are visible. He has an oval face, strong bones, and green eyes. His hair is black and worn in tousled curls.

Background: The Emperor orders House Atreides to govern the desert planet Arrakis but conspires with Baron Vladimir Harkonnen and sends troops to raid the planet’s capital, Arrakeen; this leads to Leto’s death and the destruction of House Atreides.
Personality: Paul is a quiet, disciplined, and intense young boy. He is also brilliant due to his mentat training. His character follows the basic storyline of a heroic personality who has a tragic beginning but acquires superhuman powers and defeats his enemies.
Development: Paul was to be a girl by Reverend Mother Gaius Helen Mohiam’s order. She told Jessica, a votary of the Bene Gesserit, to conceive a daughter that would bear the Kwisatz Haderach, a powerful clairvoyant being. However, Jessica followed her heart and gave birth to Paul, who eventually rose to the pinnacle of the universe.
Significance: Paul faces and defeats the hardships he meets on his journey to the throne. First, he proved his manhood to the Fremen and took the name Usal Paul Muad’Dib. Then, he drank the Water of Life, which put him into a coma for weeks. Eventually, he survived and returned with telepathy powers.
Analysis: Paul’s meteoric rise to power was only possible because of his zeal to bring radical change. His thirst for vengeance and glory fueled his resolve and gave him the strength to conquer his enemies.
Baron Vladimir Harkonnen
Role: Vladimir Harkonnen is the Baron of the House of Harkonnen.
Key Info: He is the ruler of the great house Harkonnen, which formerly controlled Melange production on Arrakis.

Background: After withdrawing from the planet, Baron Vladimir conspires with the Emperor to destroy the House of Atreides.

Analysis: With the drop in spice production, the Emperor sends spies doubting Vladimir’s loyalty. On reaching Arrakis, the Emperor seizes a Fremen outpost, capturing Alia, Paul’s sister. However, Paul leads an attack on Arrakeen, and Alia poisons Baron Vladimir, killing him. Before dying, she tells him of their blood relationship.
Chani
Role: Chani is a Fremen woman from the Sietch Tabr community.
Key Info: After getting absolved into the community, Paul falls in love with Chani, and she bears him a son, who they name Leto II.

Significance: Chani’s love and loyalty to Paul was one of the key factors that gave him legitimacy among the Fremen.

Lady Jessica
Role: Lady Jessica is Paul’s mother and Leto’s concubine.
Key Info: She has an oval face with bronze-colored hair. Her features are from Frank Herbert’s wife, Beverly Herbert.

Background: He did it because Piter De Vries promised to free his loved one.
Personality: Yueh has black hair, a squarish blockhead, purple lips, a narrow chin, and a mustache.
Development: Yueh betrays Leto because his wife, Wanna, was held prisoner by Baron Harkonnen, who promised to set her free if he handed Leto to him.

Analysis: Yueh’s betrayal and the destruction of House Atreides were the ingredients that turned Paul into the incredible fighter he was. Without Yueh’s actions, Paul might have likely died, and the story of “Dune” would have ceased to exist.

Significance: Feyd gets killed by Paul after he challenges him to fight in the act of kanly.
Analysis: Feyd-Rautha was an evil young man whose passion for control led to him becoming a strong leader. If everything went according to Bene Gesserit’s plan, he was supposed to marry a female version of Paul Atreides, who would have birthed the Kwisatz Haderach.

Development: Due to his actions, Paul and his mother escape into the desert, where Paul gains superhuman powers and leads a resistance against the Padishah empire.
Significance: Paul dethrones Shaddam, forcing him to give his first daughter, Princess Irulan, as a wife, sealing Paul’s place as Emperor.
Analysis: Shaddam was a man who let his fear of losing control destroy his rule. If he had not done anything to House Atreides, he most likely would never have lost the throne. However, his paranoia led to Paul’s quest for revenge.
