Fantasy Novel Writing Prompts

A good fantasy novel writing prompt should spark imagination by using keywords like castle, forest, hidden library; character keywords like wizard, thief, knight; and conflict keywords like curse, prophecy, betrayal.

You can even add magical elements like dragon, portal or an enchanted object. Adding tone (mysterious, dangerous, cursed) makes the prompt inspiring and easy to grow into a novel.

Prompt 1: A hidden magical realm only accessible through a forgotten library book.  

Inside a dusty old library that no one visits anymore, a teenager finds a book with no title and strange symbols on its cover. When they open it, the words shift and glow, pulling them into a hidden magical realm that exists only through the book’s pages. This world is full of creatures from forgotten myths, talking forests, and cities built in the sky. But the realm is unstable, if the book is destroyed, the world will vanish forever. The protagonist must decide: do they risk their life to save a magical land that no one else believes exists?

Prompt 2: A thief discovers they’re the last descendant of a banished sorcerer.

Soon, they cannot remember why they wished for anything at all. When they realize the mirror feeds on human memories to survive, the main character must find a way to break the curse before they forget themselves entirely.

Prompt 4: A dragon and a knight form an unlikely alliance to save their world.

But when a new threat, a darkness that devours both humans and magical beings, rises, one young knight and a wounded dragon find themselves forced to work together. Neither trusts the other at first, but they slowly realize their strengths complete one another: the dragon’s fire and ancient wisdom, and the knight’s courage and loyalty. Together, they must unite kingdoms and clans who have been enemies for ages, or watch their entire world turn to ash.

Prompt 5: A forgotten prophecy predicts the rise of a hero who doesn’t believe in magic.

In an old ruined temple, scholars uncover a prophecy carved into stone: a hero will rise to defeat the Shadow King. The prophecy describes someone ordinary, someone alive today.
