Fantasy story ideas: 50 plots by subgenre, from epic to cozy

Good fantasy story ideas start with one rule that makes trouble, a person that rule hurts most and a turn that changes what they want. The 50 ideas below are sorted by subgenre, from epic fantasy and sword and sorcery to cozy, dark and historical fantasy, because each subgenre runs on a different kind of conflict, not just a different scale. Every idea names a protagonist, the magic or the world, the turn and why it works. For one-line sparks to write from in twenty minutes, use the 100 fantasy writing prompts instead.

Each idea has four parts. The first sentence gives the premise and the protagonist. The magic or the world is the one rule the story turns on. The turn is the moment the problem changes shape. Why it works names the pleasure the idea offers readers of that subgenre, which is the part to keep when you change everything else.

Epic fantasy story ideas

Epic fantasy is a struggle over power: who rules, which side wins, what the world becomes. These keep the scale and find a way in through one person with an unusual job, so the war arrives as a problem on their desk.

1. The census. Ilse Varn, a junior clerk in the imperial census office, is sent north to count the empire's people before the coronation. The magic: the emperor's power grows with the number of his living subjects, so the count is a ritual as much as a record. The turn: her tally comes up a hundred thousand short, whole valleys emptied, and someone at court has been adding the dead to keep the emperor strong. Why it works: a war for a throne seen through a ledger, where one honest number can bring it down.
2. The frozen river. For four hundred years the river Anvar has kept two kingdoms apart, and Tesk, a ferrywoman, has carried both sides' messengers, smugglers and runaways. The world: the old treaty bound a river god to keep the water running and the armies apart. The turn: one winter the river freezes solid because the god has died, and both kings plan to blame the other and march across. Why it works: a borderland epic told by the one person both armies need.
3. Two kitchens. Bran Holloway cooks for the three thousand people trapped in a besieged citadel, counting out barley by the cup. The world: the citadel's wards hold as long as the fire in the great kitchen never goes out. The turn: the army outside is starving too, and its cook sends Bran a message on an arrow: the two kitchens, not the generals, could end this. Why it works: the stakes of a kingdom, seen from the people who keep everyone alive.
4. The fleet comes home. Eighty years ago the kingdom of Ormere sent its fleet west to find the edge of the sea, declared it lost and divided the sailors' estates. The world: the fleet sails back into harbor, and its crews have aged three years. The turn: Sefa Cole, the young regent's spymaster, learns that the fleet has brought back the thing it found at the edge, and that it has asked to meet the king. Why it works: rightful claims, grandchildren older than their grandparents, and wonder from the end of the map.
5. The board-keeper. For thirty years two emperors have played a single game of stones by letter, and Tamsin Hale keeps the board in the neutral city between them. The magic: every move on the board happens on the battlefield, and armies march as the stones move. The turn: one emperor dies, his heir has never learned the game, and Tamsin is the only person alive who knows every move ever played. Why it works: two empires depend on the person who was supposed to be invisible.

Sword and sorcery ideas

Sword and sorcery shrinks the stakes to one hero's skin and purse: a job, a wizard, a way out. The pleasure is speed, nerve and a clever escape.

6. The pension. Hesk, fifty-eight, a mercenary with one good knee, takes a last job to buy a farm: escort a dead sorcerer's coffin to his tomb in the salt hills. The magic: the sorcerer isn't entirely dead, and he bargains from inside the coffin. The turn: the tomb is a trap for whoever carries him, because the sorcerer needs a body, and Hesk's, bad knee and all, is the healthiest he's going to get. Why it works: a personal job, wits against wizardry and an old fighter's last scrap of pride.
7. The chain. Rasha, a rooftop thief in the desert city of Qir, is caught by Domo, the debt collector who has chased her family for years, and a curse chains them wrist to wrist. The magic: the chain shortens every time one of them lies. The turn: the curse was cast by the moneylender Domo works for, to make the debt and the debt collector disappear together. Why it works: a bickering pair, a city of bazaars and rooftops, and a villain with an accountant's mind.
8. The god in the hilt. Ama Torro has won forty bouts in the fighting pits of a river port, helped by a small god who lives in her sword's hilt. The magic: the god feeds on her opponents' fear and pays her in their strength. The turn: she is now so famous that nobody fears her, and the hungry god starts feeding on her own fear instead. Why it works: the hero's power turns on her, the oldest bargain in sword and sorcery.
9. The strike. Kesh breaks into tombs for a living in the necropolis of a dead empire, where robbing the dead is a licensed trade. The magic: the old kings' curses are real, and the robbers' guild pays the temple priests to defuse them before every job. The turn: the priests go on strike, and the guild's richest client wants a tomb opened tonight: the tomb of the priest-king who wrote every curse in the city. Why it works: a heist with ancient traps, a crooked contract and a crew with nothing to lose.
10. The fine print. The Red Lanterns, a company of eleven sellswords, are hired to defend the town of Brannock through the winter. The world: every hundred years the town owes a sorcerer in the hills a tribute of armed men. The turn: the company's captain, the only one who can read, discovers that they are the tribute, and decides to read the contract aloud to the sorcerer, clause by clause. Why it works: steel, a wizard and a loophole, delivered with a grin.

Portal fantasy ideas

Portal fantasy sends someone from our world into another, so readers learn the rules alongside them. These turn the old shape around: adults go back, and people come through the other way.

11. The child queen. At nine, Dana Whitcomb spent three years as a queen in another world and came home to the same afternoon. Now she is forty-four and a dental hygienist in Tulsa. The world: that world was saved by children, and lately its children have started summoning adults. The turn: it summons Dana back, and the tyrant she must bring down is the regent she appointed when she was eleven. Why it works: the chosen child grows up and has to answer for her childish decisions.
12. The other direction. Elin, sixteen, arrives in Manchester through a portal with her parents and little brother, refugees from a war in a world that has magic. The magic: at home she was training as a mage, but here her spells work only through English words, which she's still learning. The turn: the officers who drove her family out come through the portal too, in good suits, and apply for asylum. Why it works: the stranger in a strange land, pointed at our world, with a hard moral turn.
13. The crack in the wall. In 1958, Gwen Morgan, twelve, finds a crack in her bedroom wall in a Welsh valley town, and a girl her age writes back through it from a kingdom at war. The world: letters pass through the crack, and one night so do the girls, each into the other's bed. The turn: as the crack begins to close, Gwen, now an apprentice knight, realizes her friend has sent her to fight the war in her place. Why it works: a friendship, a swap and a betrayal that might also have been a rescue.
14. The border post. Every few years a child from our world stumbles through a door in an old hospital laundry into Ellery, and Captain Brannagh's job is to send them home before they set off a prophecy. The world: visitors from our world bend Ellery's fate simply by being there. The turn: the new arrival is fifty-three, a retired schoolteacher from Leeds who came through on purpose, and she won't leave until she finds the boy she lost through the same door in 1981. Why it works: the portal story told from the other side's customs desk.
15. The return policy. Since he was ten, Hollis Grant has spent every summer in the Ashlands. The world: each summer there lasts a decade, so his friends from the first summer are old now. The turn: his oldest friend, now queen and dying, asks him to stay and rule after her, which means giving up a life in his own world before it has started. Why it works: the portal's time slip used for love, loss and a real choice.

Urban and contemporary fantasy ideas

Urban and contemporary fantasy hides magic inside the world readers know, and it is often built like a mystery. These give the magic a day job.

16. The complaint line. Dolores Reyes answers Albuquerque's city services line: potholes, streetlights, barking dogs. The magic: one caller in fifty is a spirit who lives in the old adobe, complaining about a renovation, and she has logged them all as noise complaints for years. The turn: one night every spirit in the old town calls at once to report the same thing: something new has moved into the city, and it doesn't file complaints. Why it works: a civil servant's switchboard becomes the city's early-warning system.
17. The night pharmacist. Kofi Mensah works the overnight counter at a 24-hour pharmacy in Philadelphia and fills prescriptions for the city's hidden residents. The magic: vampires, river spirits and a minor god of parking all have conditions that need managing. The turn: someone is forging prescriptions for an ingredient that can kill a god, and the prescriber on every forged script is Kofi. Why it works: a mystery in an unglamorous workplace, with the hero framed from the start.
18. Protection. Lena Amadi, a tattoo artist in Austin, inks designs that work as wards. The magic: each tattoo protects its wearer from one danger, which the client names in the chair. The turn: her clients start dying of the one thing their tattoos don't cover, and the pattern points to a client who asked to be protected from Lena. Why it works: a personal magic, a citywide mystery and a villain who knows exactly how her craft works.
19. The lost-dog posters. Theo Banks, a dog walker in Baltimore, notices posters for lost dogs of breeds nobody has heard of, with one eye too many in the photographs. The magic: the city's hidden residents keep familiars, and someone is stealing them. The turn: every owner has lost their magic along with their familiar, and the phone number on every poster rings the apartment across the hall from Theo's. Why it works: an urban mystery that starts with a flyer on a lamppost and a hero with an ordinary job.
20. The school gate. Owen Hart, a stay-at-home dad in suburban Minneapolis, discovers that the parents at the school gate are a coven. The magic: the coven keeps the suburb safe from something in the lake, and it needs a member nobody would suspect. The turn: they invite Owen to join because the thing in the lake has already noticed him. Why it works: the comic, domestic register of contemporary fantasy, with real stakes underneath.

Fairy-tale retelling ideas

A retelling keeps what readers remember and asks a question the original never did. All five sources here are in the public domain: three tales from the Brothers Grimm, whose first volume appeared in 1812, Hans Christian Andersen's “The Snow Queen” (1844) and the Pied Piper legend, which Robert Browning turned into a poem in 1842.

21. Godfather Death. In the Grimms' tale, Death makes his godson a doctor who can tell whether a patient will live: Death standing at the head of the bed means recovery, at the foot means death. The retelling: Ana Fuentes, an intensive-care doctor in Houston, is that doctor's descendant and has the same gift. The turn: Death stands at the foot of her daughter's bed, Ana turns the girl around in the bed as the doctor in the tale turned the king, and Death, who knows the tale too, is waiting at the other end. Why it works: the retelling uses the reader's memory of the original as the trap.
22. The boy left behind. In one version of the Pied Piper legend, a lame boy can't keep up with the other children and is left behind. The retelling: forty years later, that boy is Hamelin's mayor. The turn: the Piper returns with the children, not a day older, and says the town still owes him, so the mayor must decide what to pay. Why it works: the story told by the one person the original ending left out.
23. The splinter. In “The Snow Queen,” splinters of a troll's mirror lodge in Kai's eye and heart, and he sees only what is ugly until Gerda's tears free him. The retelling: the splinter in his eye never quite washed out, and Kai, grown, works as a diamond grader in Antwerp, where seeing every flaw is a gift. The turn: Gerda comes to ask for help: the Snow Queen is dying, and only someone who sees the world's flaws can choose who replaces her. Why it works: it asks what happened after the rescue and turns the curse into a skill.
24. The flounder's long game. In the Grimms' “The Fisherman and His Wife,” an enchanted flounder grants the wife's wishes, each grander than the last, until she asks to be like God and finds herself back in her hovel. The retelling: the flounder tells it. He is a prince under a curse. The turn: the curse breaks only if he is asked for a wish beyond his power, so he has spent the whole tale leading the wife on. Why it works: the moral flips, and the greedy wife becomes the mark in a long con.
25. The false bride. In the Grimms' “The Goose Girl,” a princess's maid takes her place on the road to her wedding, and the princess's talking horse, Falada, is killed. Its head, nailed up where the princess passes each morning, still speaks to her. The retelling: the maid tells the story, and she is a better queen than the princess would have been. The turn: years into a good reign, the true princess asks her to keep the crown, but the horse's head has started telling the truth to everyone who passes. Why it works: it asks who deserves the throne and keeps the original's eeriest image.

Myth and legend retellings

Myth hands you a story readers half know and a world with gods in it. These borrow from Arthurian, Greek, Norse, Slavic and Irish tradition and move the old stories somewhere new.

26. The third throw. In Malory's Le Morte d'Arthur, Sir Bedivere twice fails to throw Excalibur into the lake as the dying Arthur asks, and when he finally does, a hand rises from the water to catch it. The retelling: Nell Bedwyr, who runs a scrap-metal yard on a Welsh hill farm, keeps the family secret: the third throw was a fake too. The turn: the Lady of the Lake turns up at the farm gate, asking for the sword back, with fifteen centuries of interest. Why it works: legend in a muddy farmyard, with a debt nobody alive agreed to.
27. The apprentice. Ione, fourteen, is apprenticed to the three Fates and learns to measure the thread of every life. The magic: each thread she measures is a person, and each cut is a death. The turn: her first cut on her own is her mother's thread, and she learns her mother gave her to the Fates to buy her own life. Why it works: the machinery of Greek myth made personal, with a choice no apprentice should face.
28. The wrong man. Hild is a Valkyrie, one of the choosers of the slain, and nine hundred years ago she carried a cook to Valhalla by mistake. The world: the warriors of Valhalla fight all day, feast all night and wait for the last battle. The turn: with that battle coming, the cook is the only person in Valhalla who knows how to do anything but fight, and the warriors start following him. Why it works: Norse myth with a workplace comedy inside it, and a real question about what an afterlife is for.
29. The hut walks. Baba Yaga is retiring, and her hut on chicken legs is choosing her successor. The world: the hut walks to the person it wants and settles in their yard. The turn: it walks to Vera Sokolova, the village schoolteacher, who has spent forty years warning children away from the forest. Why it works: folklore's most famous witch handed down to the person least willing to take her place.
30. Oisín in the care home. In the Irish legend, Oisín returns from Tír na nÓg on a white horse, touches the ground and becomes, in a moment, an old man. The retelling: Saoirse Daly, a nurse at a care home in Galway, admits a very old man found by the road beside a white horse, who asks for the Fianna. The turn: Niamh comes for him from the Land of Youth, and he asks Saoirse to tell her he has died, because he would rather die here than go back. Why it works: myth meets a care home, and immortality loses to home.

Cozy fantasy ideas

Cozy fantasy changes the kind of conflict, not just its size. Nobody has to be defeated: the trouble is a broken thing, a lost page, a sale or an old grudge, and it's settled by care, craft and community. The general who would be the villain of an epic walks into idea 31 as a customer.

31. The repair shop. Maren Dahl, a retired battle-mage who lost her sight in the last war, runs a repair shop for enchanted household things in a hill town. The magic: a broken charm can be mended only by someone who hears the story of how it broke. The turn: her new customer is the general who ordered the battle that blinded her, now a widower with a broken music box. Why it works: healing through small, careful work, and a reconciliation across a workbench.
32. The charter. Pim, a hobgoblin, runs the lending library in the mountain village of Little Wend, where books are lent for a favor instead of a fee. The world: the village's founding charter is the one book Pim never lends. The turn: a child borrows it anyway and returns it with a page missing, and with it the village's right to the valley. Why it works: a mystery with no corpse, where the stakes are a community's memory.
33. The retirement home. Brother Amis runs a retirement home for old heroes and their aging companions: a half-blind griffin, a phoenix that forgets which life it's on. The world: the heroes who saved the realm forty years ago now need help with the stairs. The turn: the Dark Lord they defeated, also old, frail and alone, applies for a room. Why it works: found family stretched to include the enemy, long after the war.
34. The allotment. Hattie Moss inherits her late aunt's plot in a community garden where every plot grows something impossible. The magic: moonflowers that hum, beans that climb toward whoever planted them, a pumpkin that won't stop growing. The turn: the council announces the land will be sold, and the gardeners' only hope is to win the county fair with something no judge has ever seen. Why it works: community stakes, a fair and a contest where losing still feels warm.
35. The tutor. Cinder, a very old dragon, tutors the village children in arithmetic in exchange for firewood. The world: the village has quietly depended on the dragon for three generations. The turn: a royal tax assessor arrives to value the dragon's hoard, which turns out to be every exercise book the children have ever handed in. Why it works: a huge creature, small stakes and a great deal of heart.

Here is how idea 31 might open, with the turn already in the room by the last sentence:

The immediate problem comes from the world's one rule: a broken charm can be mended only by someone who hears the story of how it broke. Maren can't fix the box without listening to the man whose orders cost her her sight, so the rule turns an ordinary repair into the conversation she has avoided since the war. The world arrives through a craft and a sense, not a lecture, and the scarf tells you who the customer is a beat before his voice does. His arrival is the story's inciting incident, and it lands in the first paragraph, so the reader knows what the story is about before anyone explains it.

Dark fantasy and grimdark ideas

Dark fantasy and grimdark trade heroism for cost: every victory is paid for, often by someone else. These keep the violence mostly offstage and the moral weight in plain view. Where dark fantasy shades into fear, the horror story ideas pick up.

36. The plague of lies. Edda Rusk is a plague doctor in the walled city of Varno, where the sickness spreads with every lie told inside the walls. The magic: truth slows the plague, so the healthy are the honest. The turn: the duke's peace rests on one great lie, and the only cure is a truth that would start a civil war. Why it works: a choice between two kinds of ruin, with no clean option.
37. The vote. Corporal Ash Venn is the necromancer attached to a losing army, raising the regiment's own dead to hold the line. The magic: the risen keep their memories and their opinions. The turn: the dead begin voting in the regiment's council, and they now outnumber the living. Why it works: the moral grime of using your friends' bodies, and a shift in power nobody can undo.
38. The witch-finder. Brother Lucan is the most successful witch-finder in the Holy Marches because he is a witch himself and can sense the others. The world: the church burns what it finds, and Lucan has fed the fires for twenty years to keep his own secret. The turn: he is sent to try his sister, who knows exactly what he is. Why it works: hypocrisy at the center, and a trial with no good verdict.
39. The bone harvest. Vesna digs bones from old battlefields for the guild that carves them into charms. The magic: a soldier's bone, carved right, protects a living person from violence. The turn: demand has outrun the old battlefields, and Vesna discovers that the guild has started arranging new ones. Why it works: war as an industry, seen by a worker at the bottom of its supply chain.
40. The deserters. Six deserters from the armies of two cruel empires find a village in the hills that will shelter them if they defend it. The world: neither empire is the good one, and both are coming. The turn: the army marching on the village is the regiment four of them deserted from, led by the officer they left for dead. Why it works: no clean side, only the people in front of you and the debts you ran from.

Historical fantasy ideas

Historical fantasy puts magic into a real time and place, so the history does half the worldbuilding. Check every detail you can, and invent only the magic.

41. The ice road. Detroit, 1928. Jo Rourke runs Canadian whiskey across the frozen Detroit River at night. The magic: the river's drowned keep the ice thick for any runner who pays them a bottle a crossing. The turn: a Prohibition agent who went through the ice last winter has joined the drowned, and this season the river wants a runner instead of whiskey. Why it works: a real smuggling route with a supernatural toll, and a debt somebody has to pay.
42. The fault line. San Francisco, April 1906. Lin Wei, fifteen, apprenticed to a Chinatown geomancer, can feel the moods of the earth under the city. The magic: geomancers keep the old lines of force calm, and Lin feels them tightening. The turn: she has three days' warning of the earthquake, and no one in power will listen to a girl from Chinatown, so she has to decide whom she can save. Why it works: a known catastrophe as a ticking clock, and magic that can't change history, only who lives through it.
43. The copyist. Yorkshire, the 1150s. Sister Agnes copies manuscripts in a small priory, and her mistakes come true: a slip of the pen moves a river. The magic: only her errors work, and a perfect copy changes nothing. The turn: the bishop learns what her mistakes can do and asks her to copy the king's charter with a few deliberate errors. Why it works: the daily life of a real period, one magical difference and politics ready to exploit it.
44. The debunker. London, 1890. Edith Blake exposes fraudulent mediums for a society of skeptics, and she is very good at it. The magic: almost every séance is a trick, and Edith knows every trick. The turn: she meets a medium who is real and terrified, because the dead have stopped speaking to her and started asking for Edith. Why it works: a skeptic in an age of spiritualism discovers she is the one with the gift.
45. The river luck. The Mississippi, 1875. Cora Fontaine deals cards on a riverboat between St. Louis and New Orleans, and she can see luck hanging over people like weather. The magic: luck can be won at the table and carried off in a pocket watch. The turn: one passenger has been winning other people's luck all the way downriver, and by New Orleans he'll have enough to sink the boat with everyone else on it. Why it works: a closed setting, a ticking clock and an era full of cardsharps.

Coming-of-age and magic school ideas

Stories about growing up through magic ask who the protagonist will become, which is why school stories suit them. Critics call the wider form the bildungsroman.

46. The night curriculum. Rafi Okon, the first student from the fishing villages to win a place at the Collegium, pays his way by scrubbing the towers at night. The world: by day the school teaches safe, ceremonial magic to the children of the rich. The turn: at night the ghosts of expelled students teach the walls what the Collegium forbids, and their lessons are better. Why it works: the underdog's school story, with class politics and a hidden curriculum.
47. The familiar that never came. Every child in Fennick bonds with an animal familiar at thirteen, and Juno Ferris's never arrives. The magic: magic reaches people through their familiars, so Juno is the only person in town no spell can touch. The turn: when the town's familiars turn on their humans, the girl nobody could enchant is the only one who can walk among them. Why it works: the fear of being left out, turned into the thing that saves everyone.
48. Night class. Delia Ross, fifty-two and recently divorced, signs up for Introduction to Practical Enchantment at her local community college. The world: magic is real, licensed and taught like plumbing. The turn: her seventeen-year-old daughter is in the same class, and she is much the better witch. Why it works: a magic school story where the growing up happens at fifty, for both of them.
49. The prisoner. Teo, sixteen, a page in the royal household during a civil war, is ordered to carry meals to a prisoner in the north tower. The magic: the prisoner teaches him a spell through the bars every night. The turn: the prisoner is the rebel queen, and she is teaching him because she knows he is the king's unacknowledged son. Why it works: growing up through divided loyalties, with the enemy as the teacher.
50. The exchange student. Maya Nair is the first human exchange student at a school for the fae. The world: the fae cannot lie, which makes them dangerous in bargains and helpless against anyone who can. The turn: the faculty ask Maya to teach a class on lying, and the first student to sign up is the heir to the throne. Why it works: a fish-out-of-water school story with a reversal of power.

Test an idea before you commit

Before you build maps and languages, run the idea past these six checks. Each takes a minute, and a no is cheaper now than at chapter twelve. If the idea passes, write it as a logline and see whether you still want to know what happens next.

The last check matters more than it looks. An opponent with a reasonable want, like the officers applying for asylum in idea 12 or the bishop in idea 43, gives the plot something to push against. The guide to writing a villain covers how to build one.

Make a familiar idea yours

Most of the ideas above start from something readers already love: a chosen child, a dragon, a fairy tale. Three moves make the familiar feel new.

• Change the viewpoint. Tell the story from the person the original ignored: the maid in “The Goose Girl” (idea 25), the flounder (24), the customs officer at the portal (14).
• Change the scale. Keep the epic stakes and watch them from somewhere small: a ledger (1), a siege kitchen (3), a city services switchboard (16).
• Change the setting or the era. Put the myth where it has never been: Oisín in a Galway care home (30), Excalibur in a Welsh scrapyard (26), a Valkyrie's mistake in Valhalla's kitchens (28).

Whichever move you make, let it show on the first page, the way the opening of idea 31 in the cozy section brings a whole war into a repair shop through one scarf.

Fantasy ideas that need rethinking

• A destiny instead of a want. A prophecy can start a story, but on its own it rarely drives one. Give the chosen one something the destiny will take away.
• A villain who wants evil. An enemy who wants darkness for its own sake is a weather system. Give them a want a reasonable person might share, as the villain ideas do.
• Magic without a price. If magic can solve any problem, readers have little reason to worry. One rule and one cost per idea is enough to start.
• A world that is only scenery. If the world's difference never touches the protagonist's choices, it's decoration. Every world rule above creates someone's problem.
• A borrowed culture without the homework. Medieval Europe isn't the only option, but any real culture you borrow needs research. If you draw on a living culture's beliefs, read its own writers and find readers from inside it.
• An idea without a turn. A premise that is the same on the last page as on the first is a situation, not a plot. Write the turn in one sentence before you start, and check it against the character arc you want.

Fantasy ideas grow notes fast: places, rules, names, a calendar. Keep each magic rule and its cost written down from the start, in the worldbuilding template or, if the idea is series-sized, the series bible template, which keeps names, dates and rules straight across volumes.

Once a few chapters exist, attach those notes and ask the Strokes Assistant to review the chapters against them. It tells you what's inconsistent, such as a spell that costs something in chapter three and nothing in chapter nine.
