Writing about magic means you can access the areas of your mind that you don’t normally use, freeing up imaginative ideas. But it only works if you impose constraints, and you need to decide how these are integrated into your story.
Magic is multifaceted. In historical terms, high magic was practiced by scholars, and was often based on ancient texts and arcane knowledge. Whereas folk magic – including herbalism and fortune telling - was practised by women.
There are many ways of introducing magic into your story. You might create an entirely invented world, with its own rules, like Middle Earth or Earthsea. This is magic as fantasy. Related to this is the convention of a portal which leads to an invented world from this one.
Or you might make magic integral to the everyday world. For instance Shirley Jackson’s We Have Always Lived in the Castle is set in a world similar to late-twentieth-century America, but which encompasses witchcraft. A similar approach is to use surreal magic in a narrative, in which everything is "off" and weirdness is normal. An example is Leonora Carrington’s "The Debutante," a short story in which a debutante morphs into a hyena.
Currently, there is a vogue for retelling folk and fairy tales and giving them contemporary resonance. Angela Carter is one of the most influential writers in this field. Dark folk traditions are also inspiring stories in which nature is sentient or sinister, and the past haunts the present through the landscape.
So what are the tactics that you might use? Spreading your net as wide as possible at the start is essential. It’s important to read /watch / absorb anything that interests you and has magical resonance. For instance, I just saw Ingmar Bergman’s The Seventh Seal, in which a man plays chess with Death, a haunting, unforgettable image.
You might also visit potentially inspiring places, again, keeping an open mind. Go to old cities, museums, remote places in nature. Writers like Alan Garner and C.S. Lewis were deeply inspired by the natural world.
Another tactic is to try to rediscover your childish belief in the possibility of magic. Try writing down everything you can remember about a time in your childhood when you were scared, or left alone, or lost. Write down as much as you can about your feelings then, and try to recall as much detail as possible. Magic works best in fiction when it is interwoven with the everyday – think of Harry Potter and the Dursleys.
Familiarise yourself with folk tales and myths. Grimms’ Fairy Tales is a good place to start, but there are fairy tales and fables from all over the world, varied and colourful, often with similar themes and tropes. Old stories can be repurposed time and time again.
Using magic in a story means embedding it into the narrative. So the rules that apply to story-telling generally apply here. Traditionally, stories are about characters who want or lack something, who seek a goal, are blocked or challenged in getting to that goal, and who eventually change, and if the story has a happy ending, get what it was they wanted, or something different but slightly better.
Don’t let the magic in your story solve all the problems your characters face. If you want your story to be engaging, then you need to limit the access your characters have to magical power. Otherwise, everything is too easy, there are no challenges, and therefore no conflict.
Make the rules of your fictional world clear to the reader from the beginning. Be consistent once you have established those rules. If the magic is treated as a skill that must be learned, the stakes are higher. Create barriers and challenges. Impose limitations and rules – for example – a spell can only be cast in specific circumstances.
Your characters must earn their rewards. Their achievements will only feel satisfying to the reader if the characters had to work for it.
All writers are dealing with magic to an extent – it’s a proxy for pure imagination. If you can make your readers believe in the magic in your story, you can make them believe that all the events are real.

A hagtale, a dark fable, a story told around winter’s fires and known to Shakespeare but never written down. Until now.
In eleventh-century Scotland, feral wolf-child Wulva is brought up by witches and then sent to live at a Scottish castle, where she falls under the spell of cruel, ambitious Lord Macbeth.
Three hundred years later, gentle Brother Rowan goes on a strange and perilous journey to a remote and ancient monastery to write a history of the Scottish king-line.
Misfits in their own time, seekers after truth, Wulva and Rowan are deeply connected despite the centuries that separate them.
Hagtale explores the power of stories lost and found, their transformative potential, and who gets to be the owner of the tale.
