How to Write a Portal Fantasy Book Like The Lion the Witch and the Wardrobe (C.S. Lewis) in 2026

There are few images in literature as iconic as a fur coat brushing against pine needles inside a dark wardrobe. For millions of readers, that simple sensory detail is the key that unlocks a world of wonder, danger, and profound meaning. C.S. Lewis’s The Lion, the Witch and the Wardrobe is more than just a children’s book; it’s the blueprint for a genre that continues to captivate our collective imagination: the portal fantasy.

The allure is timeless. An ordinary person stumbles upon a hidden passage—a door, a mirror, a rabbit hole—and is whisked away to an extraordinary new reality. This journey is not just a physical one; it’s a transformation of the self. The protagonist, and by extension the reader, is tested, changed, and ultimately discovers a hidden strength they never knew they possessed.

For aspiring authors, the portal fantasy offers a vast canvas for storytelling. It combines the relatable struggles of the real world with the limitless possibilities of the fantastic. But how do you write a portal fantasy that stands shoulder-to-shoulder with classics like Narnia while still feeling fresh and original? How do you build a world that readers will long to visit and create a journey that resonates long after the final page is turned?

This comprehensive guide will deconstruct the magic of The Lion, the Witch and the Wardrobe, explore other landmark books in the genre, and provide you with a strategic blueprint for writing your own unforgettable portal fantasy.

Deconstructing the Magic: Why Does “The Lion, the Witch and the Wardrobe” Endure?

To write a book like Narnia, we must first understand why it has remained a cornerstone of fantasy literature for over 70 years. Its power isn’t just in its talking animals or epic battles; it’s in the masterful execution of core narrative elements that define the very best of the genre.

The “Ordinary” Protagonist as a Vessel for the Reader

The Pevensie siblings—Peter, Susan, Edmund, and Lucy—are not warriors or wizards. They are ordinary children, evacuated from London during the Blitz, dealing with boredom, sibling rivalries, and the anxieties of war. This grounding in reality is crucial. When Lucy first steps into Narnia, her disbelief and wonder are our own. We experience the magical world through their relatable, human perspective. Edmund’s temptation by Turkish Delight isn’t just a plot point; it’s a deeply human story of greed, betrayal, and the desire for recognition that any reader can understand.

For the writer: Your protagonist doesn’t need to be special before they find the portal. In fact, their very ordinariness is what makes their transformation in the new world so powerful and compelling for the reader.

The Portal as a True Threshold

The wardrobe is not merely a transportation device; it is a true threshold between two starkly different states of being. Outside is wartime Britain—rationed, gray, and governed by the strict rules of adults. Inside is Narnia—a land of myth, eternal winter, and immense moral stakes. Crossing the threshold signifies a departure from the known and an entry into the unknown, where the rules are different and the protagonist’s choices have a much greater weight.

For the writer: Your portal should be more than a plot convenience. Give it meaning. Is it hidden in plain sight? Does it require a specific key or condition to open? The nature of the portal can set the tone for the world that lies beyond.

A World Steeped in Myth and Morality

Narnia feels ancient and real because C.S. Lewis wove it from the threads of existing mythology—fauns, nymphs, centaurs, and dwarves from Greek and Roman lore, combined with a deep allegorical structure rooted in Christian theology. This gives the world a profound sense of history and depth. It’s not just a random collection of fantasy creatures; it’s a cohesive universe with its own creation story, prophecies, and a clear moral framework. The conflict between Aslan and the White Witch is a timeless battle between good and evil, sacrifice and tyranny.

For the writer: Your world needs an internal logic and history. What are its founding myths? Who are its gods or legendary figures? What are the core values that shape its societies? A well-defined moral and historical landscape makes your world feel inhabited and significant.

The High Stakes of the “Fish Out of Water” Narrative

The Pevensies are not just visitors; they are central figures in a prophecy destined to save Narnia. This “fish out of water” trope is a cornerstone of portal fantasy. The protagonists must learn the rules of this new world—its politics, its magic, its dangers—while simultaneously being the key to its salvation. This creates immediate tension and high stakes, forcing the characters to grow and adapt at a rapid pace.

For the writer: Elevate the stakes for your protagonist. They shouldn’t just be a tourist in the fantasy world. Make them integral to its fate. Their success or failure must have real, world-altering consequences.

The Modern Portal Fantasy: 15 Books Like The Lion, the Witch and the Wardrobe

While Narnia set a benchmark, the portal fantasy genre has evolved in incredible ways. These books take the core concept of traveling to another world and explore it with new themes, darker tones, and more complex characters. If you want to write in this genre, you must read in this genre.

Classic & Middle-Grade Adventures

• Alice’s Adventures in Wonderland by Lewis Carroll: The quintessential portal fantasy, where a fall down a rabbit hole leads to a world of logic-defying chaos and unforgettable characters. It’s a masterclass in surrealist world-building.
• The Phantom Tollbooth by Norton Juster: A bored young boy named Milo drives his toy car through a magical tollbooth into the Lands Beyond, a world built on puns and intellectual concepts. It shows how a portal can lead to a world of ideas, not just magic.
• A Wrinkle in Time by Madeleine L’Engle: Meg Murry travels through space and time via a tesseract to rescue her father, blending science fiction with fantasy. It proves that a portal doesn’t have to be a physical door.
• Coraline by Neil Gaiman: A dark, cautionary tale where a small girl finds a door to a sinister “other” world that mirrors her own, but with a terrifying twist. It expertly uses the portal to explore themes of family and identity.
• Inkheart by Cornelia Funke: A book itself becomes the portal. The protagonist, Meggie, discovers her father has the ability to read characters out of books and into the real world, blurring the line between fiction and reality.

Young Adult & Nuanced Morality

• His Dark Materials series by Philip Pullman: A far more complex and philosophically ambitious take on the genre. Lyra Belacqua uses a device to cut windows between parallel universes, exploring themes of theology, free will, and the nature of consciousness.

– Miss Peregrine’s Home for Peculiar Children by Ransom Riggs: Jacob Portman discovers a time loop that acts as a portal to a hidden orphanage for children with strange and dangerous powers, blending vintage photography with a compelling fantasy narrative.

• The Magicians by Lev Grossman: Often called “Narnia for adults,” this series follows Quentin Coldwater, a disillusioned young man who discovers that Fillory, the magical land from his favorite childhood books, is real. It deconstructs fantasy tropes and explores the psychological toll of magic.
• Amari and the Night Brothers by B.B. Alston: A modern blockbuster that sees a young Black girl discover a hidden Bureau of Supernatural Affairs, acting as a portal to a world of magic hiding right under our noses.

Adult & Lyrical Fantasy

• Neverwhere by Neil Gaiman: A London businessman helps a mysterious girl and falls through the cracks of reality into “London Below,” a bizarre magical world that coexists with the city above, populated by forgotten figures and monsters.
• The Ten Thousand Doors of January by Alix E. Harrow: A beautifully written, slow-burn story about a young woman in the early 20th century who finds a book that tells of Doors to other worlds, leading her on a quest to find her own place in the universe.
• Every Heart a Doorway by Seanan McGuire: This novella brillianty explores the aftermath of portal fantasy. It’s set in a home for children who have returned from their magical worlds and can no longer cope with reality, poignantly examining the psychological impact of the journey.
• The Fionavar Tapestry series by Guy Gavriel Kay: Five university students are transported to Fionavar, the “first of all worlds,” where they become key players in an epic struggle against a dark god. It’s known for its deep character work and mythic resonance.
• The Chronicles of Thomas Covenant, the Unbeliever by Stephen R. Donaldson: A dark and subversive take on the genre. A cynical, leprosy-stricken writer is transported to a fantasy world where he is hailed as a hero but believes it’s all a hallucination, leading him to commit terrible acts.
• Jonathan Strange & Mr Norrell by Susanna Clarke: While not a traditional portal fantasy, it masterfully depicts the return of magic to a familiar world (19th-century England) and explores the passage into the eerie and dangerous land of Faerie, treating it as a truly alien and terrifying place.

Your Guide to Writing an Unforgettable Portal Fantasy

You’ve studied the classics and explored the modern masters. Now it’s time to build your own door to another world. This step-by-step process will help you lay the foundation for a portal fantasy that feels both timeless and innovative.

Step 1: Ground Your “Ordinary World” in Authenticity

Before your reader can believe in your magical world, they must first believe in your real one. Spend time establishing the protagonist’s life before the portal. What are their frustrations, fears, and desires? A character who feels trapped by their mundane life (like the Pevensies in the Professor’s house) has a built-in motivation to escape and a powerful reason to embrace the new world. This “before” picture provides the emotional anchor for the entire story.

Step 2: Design a Unique and Meaningful Portal

The portal is your reader’s first taste of the magic to come. Avoid generic glowing doorways unless you have a truly unique take. Consider a portal that reflects the themes of your story:

• A book whose words rearrange to describe a new place.
• A reflection in a puddle that shows a different sky.
• A specific song that, when played, transforms the room.
• An abandoned subway station where a train to another world sometimes stops.

The rules of your portal are also important. Is it always open? Does it move? Can anyone use it, or only certain people? These details add texture and mystery to your narrative.

Step 3: World-Building Your Magical Realm

This is where your imagination can run wild, but it needs structure. Don’t just list cool creatures and locations. Build a cohesive ecosystem. Ask yourself critical questions:

• History & Lore: What is this world’s creation myth? Are there ruins of ancient civilizations? What are the legendary stories everyone knows?
• Society & Politics: How is the world governed? Are there kingdoms, republics, factions? What are the sources of conflict?
• Culture & Customs: What do people eat? What holidays do they celebrate? What are their beliefs about life and death?
• Flora & Fauna: What creatures inhabit this land, and how have they adapted to its environment? How do they interact with the populace?

Creating a world with this level of detail is essential for immersion. Just as a historical fiction writer must meticulously research their setting to make it feel authentic, as we explored in our guide on writing a book like The Book Thief, a portal fantasy author must build their new world’s history and culture from the ground up to make it believable.

Step 4: Develop a Protagonist Who Is Changed by the Journey

Your protagonist must not remain the same person they were when they stepped through the portal. The new world should challenge their beliefs, force them to confront their flaws, and unlock their hidden potential. Map out a clear character arc. If they were timid, they must learn to be brave. If they were selfish, they must learn to sacrifice. The external plot (saving the world) should be a catalyst for their internal plot (becoming a better, stronger version of themselves).

Step 5: Define the Rules and Costs of Your Magic System

Magic without rules or limitations is boring and kills narrative tension. Establish a clear “magic system.” It doesn’t have to be rigid, but there should be an internal logic. Where does magic come from? Who can use it? What are its limits? Most importantly, what is its cost? Perhaps using magic drains one’s life force, corrupts the soul, or attracts unwanted attention. The cost of magic is often more interesting than the magic itself.

Step 6: Weave in Compelling, Universal Themes

The best portal fantasies are about more than just adventure. Narnia is about faith, sacrifice, and redemption. His Dark Materials is about authority, rebellion, and the loss of innocence. What is your story really about? Consider themes like:

• Found family vs. biological family
• Duty vs. personal desire
• The price of power
• Environmentalism and the natural world
• Destiny vs. free will

A strong central theme will elevate your story from a simple adventure to a piece of literature with lasting emotional impact.

Step 7: Structure Your Plot: The Journey and the Return

Portal fantasies often follow a clear structure. The protagonist starts in the ordinary world, enters the magical world, faces a series of trials that escalate in difficulty, confronts the main antagonist in a final climax, and then must make a choice: stay or return. The return journey is just as important as the initial one. How has the protagonist changed? How do they reintegrate into their old life? Do they bring a piece of the magic back with them? This final stage solidifies the character’s transformation and provides a satisfying conclusion for the reader.

Frequently Asked Questions About Writing Portal Fantasy

What defines a portal fantasy book?

A portal fantasy is a subgenre of fantasy in which a character or group of characters is transported from their familiar, “normal” world into a different, often magical, world. The key element is the “portal” itself—a physical or metaphorical doorway that serves as the threshold between the two realities. The plot typically revolves around the protagonist’s journey of discovery and adaptation in this new world.

What is the difference between portal fantasy and high fantasy?

The main difference lies in the setting and the protagonist’s origin. In portal fantasy, the story begins in our world, and the protagonist is an ordinary person who travels to a magical realm. High fantasy, like The Lord of the Rings, is set entirely within a fictional, secondary world with its own established history and rules, and the protagonists are native to that world. While a portal fantasy contains a high fantasy world, the journey from our world to that one is its defining characteristic.

Why are children often the protagonists in portal fantasy?

Children make ideal protagonists for portal fantasy for several reasons. They are more likely to be open-minded and accepting of magic than cynical adults. Their “ordinary” world is often one of limited agency, so entering a world where their actions have immense consequences creates a powerful coming-of-age narrative. This allows the story to explore themes of growing up, discovering one’s identity, and finding courage.

How do you make a fantasy world believable?

Believability comes from consistency and detail. Establish clear rules for how your world works—its magic, its physics, its societies—and stick to them. Add small, sensory details that bring the world to life: the smell of the alien food, the texture of the clothing, the sound of the local dialect. Give the world a history that feels lived-in, with its own legends, ruins, and unresolved conflicts. A believable world feels like it existed long before your protagonist arrived and will continue long after they leave.

Your Journey Begins Here

Writing a portal fantasy is an act of creation in its purest form. It is the art of building a bridge between the world we know and the world we dream of. Like C.S. Lewis, Neil Gaiman, and countless others, you have the power to open a door for your readers, inviting them on an adventure that will challenge, enchant, and ultimately change them.

The journey requires meticulous world-building, deep character development, and a firm grasp of narrative structure. It is a challenge, but the reward is a story that can become a cherished escape for readers, a world they return to again and again for comfort and inspiration.
