Dune

A noble family is destroyed for control of one desert planet's only resource — and the empire built on it echoes real oil politics, real desert science, and a real, ancient prophecy.

Today: you'll tell the story of Dune — a betrayed family, a boy who flees into the desert, and the question of whether he becomes a saviour or a disaster — discover how much of the world underneath it is real, and master the grammar English uses to link one condition to its consequence: the first conditional, plus unless / as long as / provided (that) / so long as.
Before we begin — talk it through: Imagine one substance controlled almost everything — travel, trade, power — and it only existed in one harsh, dangerous place. Who do you think would end up controlling it? And do you trust leaders who claim to be chosen by destiny?

The words for today's story

Work through the four short activities. Each word is shown in a situation that gives its meaning away — no need to know the film yet. Say your answer out loud first, then reveal.

A. Infer from context — what does the bold word mean?

1. The arid plateau hadn't seen rain in over a decade; every plant that survived there had learned to live on almost nothing.
arid (adj) — extremely dry; receiving little or no rainfall.
2. After thirty years in power, the old regime had become so entrenched that no rival dared to challenge it.
entrenched (adj) — firmly established and very difficult to change or remove.
3. The general's treachery cost thousands of lives: he secretly sold his own army's plans to the enemy for a fortune.
treachery (n) — the betrayal of someone's trust; disloyalty involving deceit.
4. The invading empire moved swiftly to subjugate the smaller kingdoms, forcing them to pay tribute and obey its laws.
to subjugate (v) — to conquer a people or place and bring them completely under your control.

B. Closest in meaning — which one is nearest?

5. covert is closest in meaning to: (a) open   (b) secret   (c) loud
(b) secret — covert (adj) means hidden, not openly acknowledged or shown.
6. ruthless is closest in meaning to: (a) merciful   (b) cruel and without pity   (c) careless
(b) cruel and without pity — ruthless (adj) means having no compassion, willing to cause harm to get what you want.

C. Which meaning fits? (choose a, b or c)

7. She had long coveted her neighbour's land, watching it hungrily for years before finally finding an excuse to seize it.
To covet something is: (a) to protect it fiercely; (b) to want it intensely, especially if it belongs to someone else; (c) to give it away freely.
(b) — to covet (v) — to want something very much, especially something that belongs to someone else.
8. After years of holding the throne by force, the ageing king finally relinquished it, handing power to his daughter without a fight.
To relinquish something is: (a) to seize it violently; (b) to give it up or hand it over; (c) to hide it from view.
(b) — to relinquish (v) — to give up possession or control of something, often reluctantly.

D. Infer from context — two bigger ideas

9. The old prophet's zealots followed him into the harshest desert without question, certain that whatever he commanded must be right.
a zealot (n) — a person who is fanatically devoted to a cause or belief, often to an extreme or uncritical degree.
10. The villagers spoke of the healer's name only in hushed voices, treating her with a reverence usually reserved for gods.
reverence (n) — deep respect and awe, often close to worship.

Now use them — out loud

Talk it through before we watch:
  • Using arid, covet and subjugate, predict: what kind of conflict do you think unfolds on a desert world that everyone wants?
  • Which of these words describe a person's character, and which describe a situation? Sort them out loud and say why.

The film, in three parts

Denis Villeneuve's Dune (2021) and Dune: Part Two (2024), based on Frank Herbert's 1965 novel. Read each part, try the quick check from memory, then discuss. (There are spoilers ahead — that's the point; we're here to talk about it.)

Part 1 — A poisoned gift

In the far future, the most valuable substance in the universe is "the spice," melange — a drug mined only on the desert planet Arrakis that extends life, expands the mind, and, crucially, makes interstellar travel possible. Whoever controls the spice controls the empire. For decades the brutal House Harkonnen has stripped Arrakis of spice while crushing its native people, the Fremen.

Then the Emperor orders House Atreides — led by the honourable Duke Leto, his wife Lady Jessica, and their son Paul — to take over spice production on Arrakis instead. It looks like an honour. It is, in fact, a trap: the Emperor secretly fears Duke Leto's growing popularity and has conspired with the Harkonnens to destroy House Atreides once it is exposed and isolated on Arrakis.

The trap closes fast. Aided by a trusted physician who has secretly betrayed the family, the Harkonnens and the Emperor's own elite soldiers overrun Arrakis and kill Duke Leto. Paul and his mother escape at the last moment into the deep, deadly desert — the one place the Harkonnens fear to follow.

Quick check — answer from memory, then reveal:

1. Why does the Emperor really send House Atreides to Arrakis?

2. What happens to Duke Leto, and how do Paul and Jessica survive?

1. It is a trap: the Emperor fears the Duke's popularity and secretly helps the Harkonnens destroy House Atreides once it is exposed on Arrakis.

2. A trusted physician betrays the family and the Harkonnens attack with Imperial troops; Duke Leto is killed, but Paul and Jessica flee into the open desert, where their enemies fear to go.

Discuss:
  • The Emperor destroys a loyal family out of fear of its popularity. Is fear of a rival ever a reasonable basis for betrayal — in politics, business, or anywhere else?

Part 2 — Among the Fremen

Alone in the desert, Paul and Jessica are found by the Fremen, the native people who have survived on Arrakis for generations by conserving every drop of water and respecting the colossal sandworms that patrol the open sand. Jessica is secretly a Bene Gesserit — a member of a powerful sisterhood that has spent centuries quietly planting the legend of a prophesied saviour, the Lisan al-Gaib, on many worlds, in case one of their own ever needed protection among a superstitious people.

Paul must earn his place. He survives a ritual knife duel with a Fremen warrior and is accepted into the tribe, taking the Fremen name Usul and, later, Muad'Dib. Under Stilgar's leadership he learns their ways: reading the desert, wearing a stillsuit that recycles the body's own water, and — in a rite of passage every Fremen must pass — summoning and riding one of the giant sandworms.

As Paul proves himself again and again, the Fremen increasingly see in him the fulfilment of the old prophecy. Paul is torn: he begins to suspect the legend was planted deliberately, and he glimpses terrifying visions of a holy war spreading across the galaxy in his name if he ever fully embraces the role.

Quick check — answer from memory, then reveal:

1. What is the Lisan al-Gaib, and why does Jessica's sisterhood spread this legend across many worlds?

2. What must Paul do to earn a place among the Fremen, and what troubles him about it?

1. It is a prophesied off-world saviour; the Bene Gesserit sisterhood plants the legend on many planets in advance, as insurance in case one of their own ever needs protection among a superstitious people.

2. He survives a ritual duel and learns to ride a sandworm; he is troubled because he suspects the prophecy was engineered, and he foresees a devastating holy war if the Fremen follow him as their messiah.

Discuss:
  • Paul benefits from a prophecy his own mother's order deliberately planted among the Fremen. Does it matter whether a "chosen one" is real or manufactured, if people believe it?

Part 3 — The making of a messiah

To gain the full powers of prophecy that run in his bloodline, Paul drinks the lethal Water of Life and survives it, becoming the Kwisatz Haderach — a being who can see across time. What he sees horrifies him: if he leads the Fremen as their prophesied leader, a holy war will sweep the galaxy in his name, killing billions who have never even heard of Arrakis.

Grief for his father, love for the Fremen woman Chani, and the sheer momentum of a desperate people's faith all pull him forward anyway. Paul unites the most zealous Fremen of the deep south under the banner of the prophecy, leads a devastating assault on the Harkonnens and the Emperor's forces at Arrakeen, and personally defeats the Emperor's champion, Feyd-Rautha, in single combat.

Paul forces the Emperor to abdicate and claims the throne, marrying the Emperor's daughter for political power while Chani, who despises the religious cult growing around him, is left heartbroken. The film ends with Paul now in complete control of the empire's spice — and of an army of believers ready to carry his holy war to every corner of the galaxy.

Quick check — answer from memory, then reveal:

1. What does Paul become after drinking the Water of Life, and what terrible vision does it give him?

2. How does the story end for Paul, and how does it end for Chani?

1. He becomes the Kwisatz Haderach, gaining full prescience; he foresees a galaxy-wide holy war fought in his name if he takes up the role of prophesied leader.

2. Paul defeats the Emperor's champion, forces the Emperor to abdicate, and takes the throne and control of the spice; Chani, devastated by his political marriage and the cult forming around him, is left behind emotionally as he embraces his destiny.

Discuss:
  • Paul sees the disaster coming and chooses his path anyway. Does foreseeing a catastrophe and causing it regardless make someone more, or less, responsible for it?

Grammar — conditionals of cause & consequence

Few worlds run on tighter chains of cause and consequence than Arrakis: if the spice stops, everything stops; unless the Fremen protect their water, they die; as long as the sandworms rule the open sand, no army can simply march across it. This is exactly what the first conditional and its cousins — unless, as long as, provided (that), so long as — are built to express.

The building blocks:
• if + present simple, … will + base verb — a real, likely cause and its predicted effect: "If the spice stops flowing, the whole empire's economy will collapse."
• unless = "if … not" — names the one thing that would block the result: "Unless the Fremen conserve every drop, they will not survive the open desert."
• as long as / so long as / provided (that) + present simple, … will — a condition that must keep being true for the result to hold: "As long as the sandworms patrol the open sand, no army will cross it safely." "Provided (that) a stillsuit's seals hold, a person can survive weeks in the deep desert."
Feel the difference:
• unless usually sounds like a warning — it names the exception that would break things.
• as long as / so long as / provided (that) sound more neutral — they simply state the ongoing condition that keeps something true, good or bad.

1. Complete with the correct form

Read the connector already given and complete the verb.

1. Unless Paul masters the ways of the Fremen, the open desert (kill) him within days.

2. As long as House Atreides controls Arrakis, the spice (flow) to the rest of the empire.

3. If the Harkonnens ambush the spice harvesters again, House Atreides (lose) its foothold on the planet.

1. will kill (unless = the one thing that stops the result)

2. will flow (as long as = the condition that keeps it true)

3. will lose (if = a straightforward real condition)

2. Choose the connector

Fill each gap with unless, as long as or provided that — whichever fits the meaning.

1. the shield wall holds, the city of Arrakeen will stay safe from a full assault. (a condition that must keep being true)

2. Paul drinks the Water of Life and survives it, he will never become the true Kwisatz Haderach. (the one thing that would block it)

3. The Fremen will follow a new leader into the deepest desert, he first proves he can ride a sandworm. (a condition set in advance)

1. As long as / So long as

2. Unless

3. provided that / as long as

3. Complete the story — mix connectors and verbs

Fill every gap. Read it aloud when you're done.

Stilgar warns Paul: " you learn to walk without rhythm, a worm (find) you fast. But you prove yourself to the tribe, we (protect) you and your mother — you never betray us."

Unless · will find · as long as / provided that · will protect · provided that / as long as / so long as

Notice the pattern: unless flags the danger that breaks the outcome; as long as / provided (that) / so long as state the condition that keeps a promise standing.

Carry this into the Speak tab — Arrakis is a chain of consequences: unless the water is saved, no one survives; as long as the spice flows, the empire holds together.

The Real Story — the world underneath Arrakis

Frank Herbert's 1965 novel is one of the most researched works in science fiction. Almost nothing in it is arbitrary: the language, the politics and the desert itself are all built from real history, real geopolitics and real ecology — and Herbert had a very deliberate warning buried inside the story.

🏜️ A desert built from Arabic and Islamic language and culture

The Fremen are closely modelled on Bedouin and other desert peoples of North Africa and the Middle East — their austere discipline, their reverence for water, and their resistance to outside powers exploiting their land. Herbert built much of the Fremen's language directly from Arabic: "Lisan al-Gaib" — roughly "the tongue/voice of the hidden or unseen world" — is the prophesied off-world saviour figure, echoing the Islamic tradition of the Mahdi, a "guided one" foretold to appear at a time of crisis. Paul's Fremen name "Muad'Dib" draws on an Arabic root connected to teaching and discipline. The novel explicitly calls Paul's holy war a "jihad" — a word the 2021–24 films avoid, using "holy war" in the dialogue instead, a deliberate softening of one of the book's most direct borrowings.

Spice is oil

The central resource of Arrakis — mined only in a harsh desert, essential to travel and trade, fought over by outside powers who exploit the native population to extract it — is very difficult to read as anything other than an allegory for oil and the geopolitics that surrounded it as Herbert wrote in the early 1960s. Herbert's friend and fellow writer Willis E. McNelly described the empire's total dependence on spice as "a thinly veiled allegory of our world's insatiable appetite for oil," and later scholars have agreed it seems impossible Herbert wasn't thinking of oil as he wrote it — even though, in later interviews, Herbert himself pointed more often to water scarcity as his central metaphor for finite, fought-over resources.

The dunes that started it all

The desert of Arrakis has a surprisingly small, real starting point: in 1957, Herbert travelled to the Oregon Dunes near Florence, Oregon, to research a magazine article about a U.S. Department of Agriculture project using European beachgrass to stop the area's shifting sand dunes from burying roads and buildings. The article — which Herbert intended to call "They Stopped the Moving Sand" — was never finished or published. But the trip pulled Herbert into years of research into deserts, ecology and how life adapts to scarcity — reportedly over 200 books, including the work of ecologist Paul Sears — which became the ecological backbone of the entire novel.

A warning, not a cheer

Herbert was explicit that he did not want readers to admire Paul uncritically. He later explained: "I had this theory that superheroes were disastrous for humankind… What happens when somebody is a superhero in fact, when we build myths around a person who is a leader? We make him or her a demigod, because we abdicate responsibility." Herbert wrote the sequel, Dune Messiah, specifically to punish readers who had cheered Paul on as a straightforward hero — showing the holy war Paul feared actually killing billions across the galaxy in his name.

Take these into the discussion:
  • Before this lesson, did you know the "spice" was widely read as a stand-in for oil? Does that change how you see the empire's dependence on Arrakis?
  • Herbert wanted readers to distrust Paul, not cheer for him. Do you think the films (or most audiences) succeed in seeing Paul that way?
  • Does it change your view of the story to know its desert religion borrows real Arabic words and a real Islamic prophecy tradition?

Speak

This is the heart of the lesson — do it all out loud. The timer keeps you going; fill the time with detail.

Useful language: reach for today's grammar to talk about cause and consequence on Arrakis — unless ("unless the spice flows, the empire will falter"), as long as / provided (that) ("as long as the sandworms live, the desert will hold its power"). For opinions: "What's striking is…", "You could argue that…", "On one level… but on another…".
Time remaining: 4:00
Task A · Tell the story (4 minutes)

Tell the story of Dune in your own words, as if to someone who has never seen it. Move through the arc: the Emperor's trap and the fall of House Atreides → Paul and Jessica's flight into the desert → life among the Fremen and the prophecy of the Lisan al-Gaib → the Water of Life and the vision of holy war → Paul's rise to the throne and Chani's heartbreak.

Work in at least five key words (arid, entrenched, treachery, subjugate, covert, ruthless, covet, relinquish, zealot, reverence), and use unless / as long as / provided (that) when you explain what holds the empire together: "as long as the spice flows, the empire will survive."

Task B · The impossible choice (4 minutes)

Paul foresees that embracing his role as the prophesied leader will unleash a holy war that kills billions — yet he does it anyway, driven by grief, love and the momentum of a people's faith. Build an argument: is it ever justified to accept a path you know will cause catastrophic harm, if it also promises to save the people closest to you? Or does foreseeing the disaster make Paul more guilty, not less?

Task C · Charismatic leaders (4 minutes)

Frank Herbert said he wrote Dune as a warning: that when we build myths around a leader and treat them as chosen or destined, we "abdicate responsibility" and stop thinking for ourselves. Is this a real danger in today's world, or is Herbert being too cynical about leadership?

Stuck for an idea? Pick one of these and run with it:

  • A real leader, historical or current, whose followers seemed to stop questioning them.
  • Whether a resource like oil (or spice) always ends up controlled by the ruthless.
  • A prophecy, superstition or "chosen one" story from your own culture.
  • Whether the ends (saving your people) can ever justify the means (a war that kills billions).
  • A film, book or story that, like Dune, tried to warn you about its own hero.
  • What you think the desert planet Arrakis will look like if the spice ever runs out.

To finish — the bigger questions

  1. Herbert built Arrakis from real oil politics, real desert ecology and a real prophecy tradition — then used all of it to warn against the very hero his story creates. Why do you think he chose fiction, rather than an essay, to make that argument?
  2. Jessica's sisterhood planted the "Lisan al-Gaib" legend generations in advance, purely as a tool of control. Does it disturb you that religious belief, in this story, is engineered rather than sincere?
  3. Paul gains power over an empire but loses Chani's trust and, arguably, his own moral compass. Who or what does he sacrifice to become "the chosen one"?
  4. Before you go — from memory: give one sentence with unless and one with as long as or provided (that) about a real cause-and-consequence chain in your own life, and explain why each fits.
