What is dark fantasy?

Dark fantasy refers to fantasy novels and short stories that incorporate elements of horror

Dark fantasy is not a definitive subgenre but rather a mood or aesthetic that generally surrounds a fantasy story. The stories typically feature violence, gore, and vengeance.

Plot ideas for dark fantasy stories are thrilling, suspenseful, and sometimes gory. 

They show a darker side to a character and often follow an anti-hero – a protagonist in a story who does not embody the typical hero and may embody the villain from another perspective.

She slides it into her bag and takes it home. Later that week, when she has time alone, the girl takes the book to the garden and starts to read it aloud.

Tips for writing fantasy

Fantasy is one of the most beloved literary genres. 

Consider the impact of JRR Tolkien’s Lord of the Rings or the immense popularity of George RR Martin’s A Song of Ice and Fire series. Look at The Way of Kings author Brandon Sanderson’s world-building skills or Neil Gaiman’s character-driven writing style. 

The vast fantasy genre is a testament to the wonders of human imagination.

So, if you want to write compelling stories, where do you begin? It helps to understand the elements that go into a great fantasy story.


Even though your characters are otherworldly, your setting unique, and your plot fantastical, that doesn’t mean that readers can’t or should not relate to your characters.  

Even the most outlandish and evil characters must have some echo of humanity in them.

Avoid clichéd, two-dimensional, vague characters or countless deranged creatures that do not contribute anything to your fantasy novel. If you’re going to include a character in your book that gives a rich life, readers may love or hate them but what’s important is that they resonate on some level.


No matter which fantasy subgenre you choose, understand that most fantasy stories feature an underdog vs. authority theme. Even in dark fantasy, where your character is an anti-hero, they usually have a more significant force working against them.

A magic system

Magic is crucial in any fantasy story, whether dark, epic, urban, or medieval. The magical elements of a particular story set it apart from the rest. 

Even though a general magic system exists and features many books, the particular style, and means of use vary. When writing your own dark fantasy story, you have full creative control over how our magic system works. 

Just remember that your story ideas still have to make sense!

A magic system is a system of laws or rules that don’t apply to the world as we know it. Supernatural forces, ancient stones, and sorcery are common magical devices that help fantasy writers immerse readers in a unique world of mythical creatures. 

Spend time crafting a seamless magic system. It frustrates readers to follow a story but see through significant holes in the narrative. Don’t let a flawed system ruin your reader’s experience. 

Gods, mythical beings, ancient dragons, the supernatural, angels, demons, sorcery, and advanced technology are all exciting and loved magic systems, so feel free to dip into any and play with the rules.

“Imagination is more important than knowledge. For knowledge is limited to all we know and understand, while imagination embraces the entire world, and all there ever will be to know and understand.”

– Michael Scott
