A world where dreams are a physical place and people can enter them. But there's a dark side - nightmares are also real and can escape into the waking world. The main character could be a 'dreamwalker' who has to stop this from happening.
Imagine a fantasy story where the stars in the sky are actually the souls of the dead. And there is a group of stargazers who can communicate with these souls. The plot could revolve around a prophecy told by one of the star - souls about an impending doom that the stargazers must prevent.
For unique characters, consider mixing different animal traits. Like a character who has the body of a human but the ears and tail of a fox. This character could have special abilities related to fox - like senses, such as acute hearing and smell. They could be a rogue or a thief, using their abilities to their advantage in the fantasy world.
One unique idea is to make the animals in a story the main characters. In the 'Narnia' fanfiction, instead of focusing on the human characters, write about the adventures of Mr. Tumnus and the other talking animals. You could also do a crossover with different historical periods. Imagine a fanfic where a character from 'Game of Thrones' ends up in the Victorian era. And for a really different take, write a fanfic where the story is told from the perspective of an inanimate object in the original work. Like the One Ring in 'Lord of the Rings' being able to communicate its thoughts and feelings.
One idea could be a story where the characters are transported to a parallel fantasy world where their quirks work differently. For example, Midoriya's One for All might give him the ability to communicate with magical creatures instead of just enhancing his strength. Another could be a pre - quirk era story in a fantasy setting, where they have to rely on magic and swordsmanship like traditional fantasy heroes. A third idea might be a time - travel plot where they go back to a crucial point in the history of heroics in a fantasy version of their world and have to make sure things happen correctly to preserve the future.
One idea could be a world where magic is tied to emotions. For example, when someone is extremely angry, their magic might manifest as destructive fire. The protagonist could be a young person who has trouble controlling their emotions and thus their magic, and they have to go on a journey to learn self - control and master their powers.
One fantasy idea could be a world where animals can talk and they have their own complex society hidden from humans. For example, squirrels could be bankers, storing nuts as currency, and birds could be messengers, flying across the land to deliver news.
One idea could be a world where magic is powered by emotions. People have to learn to control their feelings to avoid dangerous magical outbursts. For example, a young girl discovers she has the most powerful form of this magic but has trouble with her temper.
Lunaire. It gives the impression of something related to the moon, which is often associated with magic and mystery in fantasy. Also, Zephyron. It has a windy, airy feel, like a spirit or a magical being that moves with the wind.
A story about a person who discovers they have a long - lost twin and how this revelation changes their life. It could involve exploring their different upbringings and the complex relationship that develops between them.
A story about a world where people can trade memories. They go to a special market and exchange their most precious or painful memories for something else. It could explore themes of identity and regret.
A story about a group of animals who gain human - like intelligence and start to form their own society. They have to deal with issues like discrimination among different species and the struggle for power within their new society.
