Welcome to Reedsy's fantasy plot generator
Fantasy plots carry a particular burden: they have to make readers believe in a world that doesn't exist, care about rules that were invented, and feel the weight of stakes that are entirely constructed. Get that right, and the genre offers storytelling freedoms available almost nowhere else.
Our fantasy plot generator is AI-powered and built around the details you bring to it. Feed it your protagonist, your conflict, your stakes, your supporting cast, and whatever tonal and thematic details define your world — and it will return a plot structured around those elements, broken into the acts or beats of whichever narrative framework you choose.
How to use this plot generator
The Tone field matters more in fantasy than in almost any other genre, because fantasy spans an enormous range. Be specific! "Dark and morally complex, influenced by grimdark" will yield something very different from "adventurous and hopeful, suitable for all ages."
In Your protagonist, go beyond role and archetype. "A young mage" is a type; "a young mage who was trained by the empire she now has reason to distrust" is a character with a plot already growing inside her. The more specific the tension embedded in your protagonist, the more your generated plot will feel tailored rather than generic.
Use the Core conflict field to name the central struggle at the level of action, and What's at stake to name what's actually on the line. In fantasy, the two levels are often in productive tension: the external conflict (defeat the dark power, close the rift) sits above an internal one (learn to lead, accept a lineage, choose a side). You can plant both in these fields.
Themes, tropes, and other details is also worth filling out carefully. Fantasy is a genre where reader expectations around tropes are strong — naming which ones you're working with, subverting, or avoiding will help the generator produce something that fits your book rather than a generic version of the genre.
For Story structure, Hero's Journey is a natural fit for quest-driven fantasy, but Save the Cat and the 7-Point Structure work well for plots with a strong external engine. The 5-Act Structure suits epic stories with multiple major reversals.
So you want a good fantasy plot?
The test of a fantasy plot is whether it's human enough. Readers will follow your characters into invented worlds, through invented systems of magic and power, so long as the emotional logic underneath is true. The world-building is the container, whereas the human story is what fills it.
A few things worth knowing as you write:
Your magic system should have costs your protagonist can't afford to ignore. Magic in fiction is most powerful as a source of conflict rather than resolution. If magic can solve problems without consequence, it drains tension from every scene it appears in. The most memorable fantasy magic (Le Guin's equilibrium, Sanderson's metals, the debt-magic of countless folk traditions) is interesting precisely because of what it demands.
World-building belongs in the plot, not around it. The lore, the history, the geography earn its place only when it shapes what your protagonist must do or can't do. Exposition that doesn't create or complicate a problem is decoration. Build your world on the page by making your character run up against its rules, its injustices, its histories.
The internal arc and the external quest need to move together. Fantasy plots that feel hollow usually have a protagonist who defeats the external enemy but doesn't change in any way that matters. The best fantasy — from Le Guin to Tolkien to N.K. Jemisin — choreographs external event and internal transformation so tightly that you can't separate them.
The ending has to pay off the world's central question. Every fantasy world embodies a question, even if the author hasn't named it: What is power for? Can corruption be redeemed? What do we owe the dead? Your ending doesn't need to answer that question definitively, but it has to engage with it. A climax that resolves only the external plot and ignores the thematic question leaves readers feeling like something was left unfinished.
Read the literature. Ursula K. Le Guin's Earthsea cycle remains the gold standard for how internal and external plot can become one. N.K. Jemisin's Broken Earth trilogy shows what's possible when world-building and character arc are structurally inseparable.
A note on our use of AI
We built this tool for writers, which means we thought carefully about what AI should and shouldn't do here. The generator uses AI to produce fantasy plot structures that better fit your story's specific context and needs — protagonist, conflict, stakes, magic system, tone, and the shape of your world — while breaking each one out so you can see how the narrative moves.
Here's what it won't do for you: it won't write your novel, choose your story, or make creative decisions for you. It simply generates options for you.
More importantly, your inputs are not (and will never be) used to train any AI models. Treat whatever comes out as raw material: a starting point that belongs entirely to you. Every result is yours!
