30 Fantasy Writing Prompts for Epic Quests, Hidden Powers, and Chosen Ones

Fantasy is the genre most tempted by its own scaffolding. Map-making, magic-system design, taxonomy of creatures, the precise weight of the fictional coinage — all of it is genuinely pleasurable, and all of it is procrastination if it happens before the writer understands what the story is actually about. Every fantasy world that has endured did so because a character at its center had something urgent to discover, decide, or lose. The world is the pressure; the character is the point.

The thirty prompts below are organized by subgenre — epic fantasy, portal fantasy, low fantasy, and secondary world — but each one puts its weight on a character in a specific situation rather than on a premise alone. A chosen one who doesn't know what they were chosen for. A knight who has served the wrong king for thirty years. A girl who steps through a door she cannot find again. Start with the person, not the prophecy.

"Fantasy is hardly an escape from reality. It's a way of understanding it."

— Lloyd Alexander

Each prompt is designed to function as a story opener, a scene seed, or a character-revealing exercise. Use them in whatever order suits the story you're already trying to write — or let one of them be the story you haven't started yet.

Epic Fantasy

Epic fantasy asks large questions through large canvases: the fate of kingdoms, the nature of power, the cost of the choices that change the world. The challenge is grounding the scale in something particular — a single pair of hands, a single moment of refusal or consent.

1. 01 A soldier in the victorious army of a just war discovers, while processing the enemy's surrendered archives, that the cause she fought for was built on a deliberate lie. The war ended three months ago. She is still in uniform. Write what she does with the document.
2. 02 The prophecy names a chosen one. Your protagonist is not that person — they are the one who was passed over, who watched the chosen one chosen, and who now must decide whether to support someone they know is not up to the task or do nothing and let the world burn.
3. 03 A knight who has served the same king for thirty years is given an order she cannot obey and cannot refuse without consequence. Write the night before she must act, and the single conversation she has — with her squire, her horse, or no one — that reveals who she has been all along.
4. 04 Two heirs to the same throne have been raised to hate each other. They meet for the first time not in a throne room but in a dungeon, both imprisoned by the same enemy, both with information the other needs to survive. Write the first hour.
5. 05 A scholar who has spent twenty years translating a dead language finishes the final passage and realizes that the text she has devoted her life to is not what anyone believed it was — not a founding myth but a warning, and one that applies to the present. Write her decision about whom, if anyone, to tell.
6. 06 The dragon has been dead for a hundred years. The order of dragon-slayers still trains, still recruits, still receives its annual tithe from the kingdom's treasury. Your protagonist has just been inducted. Write the moment they begin to wonder whether any of it is real.
7. 07 A mapmaker in the service of an expanding empire is sent to chart the borderlands and discovers that the land the empire intends to claim is already inhabited — by people the official maps show as wilderness. Write the choice the mapmaker makes about what to draw.
8. 08 The hero is dead. The quest is won. Write the first month of the surviving companions' ordinary lives — and what it turns out they do not know how to do now that the extraordinary is over.

Portal Fantasy

Portal fantasy is the genre of the threshold — of what happens to a person when the world they were formed in is suddenly replaced by a world that operates on different rules. The best portal stories are not about the new world. They are about what the traveler discovers they were, and were not, before they crossed.

9. 09 A woman in her forties — not a child, not a chosen one — falls through a door that closes behind her. She has a mortgage, a job she can't afford to lose, and a daughter who will be home from school in four hours. Write the first twenty minutes on the other side.
10. 10 A man who crossed into another world as a teenager and spent a decade there — long enough to lose most of his native language — has finally found a way back. He is thirty-one years old. He has been gone for three days. Write his first week home.
11. 11 The portal opens only for people who need it. Your protagonist has been standing in front of it for six months, wanting desperately to leave, and it will not open. Write what the portal is waiting for her to understand about herself before it lets her through.
12. 12 Two siblings cross over together. One of them thrives in the new world — gifted, recognized, essential to the conflict that shapes it. The other is ordinary there, as they were ordinary here. Write the story from the ordinary sibling's perspective.
13. 13 The world on the other side of the portal has been waiting for a hero for a hundred years. Your protagonist arrives and is immediately recognized as the long-prophesied savior. They know, with absolute certainty, that there has been a mistake. Write their attempt to correct it without causing a crisis of faith in everyone who has been waiting.
14. 14 A girl finds a door in an old house and steps through it into a world that is not quite right — not magical, not threatening, but subtly wrong in the way that a word looks strange when you stare at it too long. Write the three days she spends trying to determine whether the wrongness is in the world or in herself.
15. 15 Someone from the other world has crossed into ours. They are not a threat and not a messenger — they are simply lost, and the person who finds them is a middle school librarian with no particular gift for adventure. Write the two weeks before anyone figures out how to send the visitor home.

Low Fantasy

Low fantasy is set in a world much like our own — or in a historical setting — where magic exists but is rare, hidden, or costly. Its power as a mode comes from the friction between the ordinary and the impossible: the magic is more frightening, more wonderful, more morally complicated precisely because the world around it is recognizable.

16. 16 In a city that runs on ordinary commerce and ordinary corruption, one person in ten thousand is born with a gift so minor it barely qualifies as magic — they can feel when someone is lying, or they can always find north, or they never lose their keys. Your protagonist's gift has just become dangerous. Write why.
17. 17 A woman who has secretly healed her neighbors for thirty years — no one has ever asked how, and she has never explained — is finally asked directly by someone who has reason to report her. Write the conversation in which she decides, for the first time, whether to lie.
18. 18 Magic in this world costs something specific and irreversible — not pain, not life force, but memory. Every spell takes something you cannot get back. Write a character who has used it too much and is beginning to lose the memories that defined them.
19. 19 A detective in a city where magic is illegal but widely used is hired to find a missing person and discovers, partway through the investigation, that the case is connected to a magical community she has spent years pretending she isn't part of. Write the point where she can no longer pretend.
20. 20 In a world where magic is inherited, your protagonist is the first in their family in four generations to show the gift — and the family has spent those four generations building a life on the assumption that it was gone forever. Write the dinner where they tell them.
21. 21 A merchant who has used a minor magic to keep his business solvent for years — nothing dramatic, just the ability to sense which trades will go badly before they happen — watches the gift begin to fail. Write the season it stops working and the decisions he makes in its absence.
22. 22 Two people who have kept each other's magical secrets for twenty years have a falling out over something mundane — a business dispute, a marriage, a borrowed thing never returned. Write the moment one of them considers using what they know.

Secondary World Fantasy

Secondary world fantasy — stories set entirely in a world that is not ours and never was — lives or dies on the same question as every other kind of fiction: do we believe in the people? The world can be as intricate and imagined as the writer can sustain, but the reader stays for the character's choices, not the world's rules. These prompts place characters in invented worlds and ask them to make decisions that reveal who they are.

23. 23 In a world where death is reversible but expensive, your protagonist is the person who decides who gets brought back and who does not. Write the case that finally breaks their professional neutrality.
24. 24 A young woman apprenticed to the kingdom's official truth-teller — whose magic compels honesty in those questioned — begins to understand that her master has been using the gift not to find truth but to confirm what the court already wants to believe. Write the case that makes this undeniable.
25. 25 Magic in this world is communal — it can only be worked by groups, never by individuals, and the strength of the magic depends on the trust among the practitioners. Write a circle whose magic is failing and the member who knows why but hasn't said so.
26. 26 A god has gone quiet. In a world where the gods have always spoken directly and often, their silence is a catastrophe — not because of what they might do, but because of what the priests and kings and armies will do in the absence of any divine check on their ambitions. Write the first month of the silence.
27. 27 Two countries have been at peace for fifty years because of a magical treaty that compels both sides to feel the other's losses in wartime — every death felt by both armies simultaneously. Someone has found a way to break the treaty. Your protagonist is the courier carrying the proof to the capital. Write the journey.
28. 28 In a world where names have power — where to know someone's true name is to have a hold over them — a child is born who has two true names, neither of which is the one her parents gave her. Write her adolescence.
29. 29 A city is built on a creature that is not quite dead — not a metaphor, but a literal geological fact: the city's foundations are the bones of something ancient and enormous that occasionally, once a generation, shifts in its sleep. Write the generation in which it does not go back to sleep.
30. 30 The magic-users in this world are not born but made — through a process that is painful, not guaranteed to work, and that changes the person who survives it in ways that cannot be predicted in advance. Your protagonist has just survived it and does not recognize, in the mirror, the person they were before. Write the first year.

The Story Underneath the Story

Fantasy's unique gift to fiction is the permission to make the metaphorical literal — to externalize the inner life of a character in ways that realism cannot. A character who cannot be honest becomes someone who cannot speak a lie without consequence. A person who has built their identity around a role that no longer fits them steps through a portal and finds their credentials mean nothing. The magic, in other words, is almost always an argument about something that is true in our world too: about power, about what we inherit, about the cost of becoming someone different from who we were raised to be.

When you use these prompts, pay less attention to the world-rules and more attention to what the central situation forces the character to decide. The best fantasy writing isn't about what magic can do — it's about what a person does when they have it, or lose it, or discover it was never what they thought.
