One idea is to have a fantasy story set in a world where dreams are a form of reality. The main character might be a dreamwalker, someone who can enter other people's dreams. They could be on a quest to find a cure for a plague that is affecting people in both the waking and dreaming worlds. Along the way, they encounter strange dream creatures, some friendly and some not. There could also be a group of dark mages who are using the plague to gain control over the dream realm, and the dreamwalker has to stop them.
One idea could be a world where magic is powered by emotions. So, when people are extremely happy, they can create beautiful, healing magic, but when angry, it turns into destructive forces. Another idea is a fantasy story about a group of misfits who find a magical map that leads them to a hidden land filled with mythical creatures that are the key to saving their own world from an encroaching darkness. Also, a story about a young person who discovers they are the reincarnation of a powerful wizard from a long - lost era and must learn to harness their past power to defeat an ancient evil that has resurfaced.
How about a fantasy story set in a world where every person is born with an animal spirit guide? However, the main character's spirit guide is a mythical creature that no one has ever seen before. This makes the character both special and feared. As the story progresses, they have to figure out how to use their unique bond with this guide to save their world from an impending doom.
One idea could be a world where magic is powered by emotions. So, when people are extremely happy, they can create beautiful, healing magic, and when they're angry, it's wild and destructive. Another could be a story about a young hero who discovers they have the ability to travel between different fantasy realms through their dreams. They must then find a way to stop an evil force that is trying to merge these realms into chaos.
One idea could be a world where magic is tied to emotions. So, when someone is extremely happy, they might accidentally make flowers bloom everywhere. Another could be a story about a group of misfits who find an ancient map leading to a hidden realm full of magical creatures that can talk. They have to face various challenges like treacherous terrains and dark magic along the way.
Well, how about a story where the main character is a shape-shifter trying to protect their secret in a world where magic is forbidden? Or maybe a tale of a lost kingdom that reappears after centuries, and its people must adapt to a changed world filled with new magic and challenges.
One idea could be a quest to find a magical artifact that has the power to restore balance to a chaotic world.
Another good idea is a story about a magical library. Every book in this library is a portal to a different fantasy realm. The librarian, who is a powerful wizard, has lost the key to the most dangerous book that holds an ancient evil. A novice adventurer stumbles upon the library and must help the librarian find the key before an evil sorcerer does.
One idea is to start with a sudden and unexpected event. Maybe a portal to another dimension opens up in the middle of a normal town square, and the chaos that ensues sets the stage for the story. It grabs the reader's attention right away.
One idea could be a werewolf who is a prince in a hidden werewolf kingdom. He falls in love with a human girl from a neighboring village. But their love is forbidden as the werewolves and humans have been at odds for centuries. He has to fight against the old traditions and prejudices of both his kind and the humans to be with her.
Consider a story set in a fantasy realm where different magical races are at war. A protagonist could emerge to try and bring peace. You could build rich cultures for each race and throw in some unexpected plot twists.
