Well, for a brilliant magic fanfic, you could focus on a character who discovers they have a very rare and powerful form of magic that no one has seen in centuries. This character then has to hide their power from those who would misuse it. Or perhaps create a world where magic is powered by emotions, so when people are extremely happy or sad, their magic is at its strongest. Also, a story about a magic - using detective who uses magic spells to solve crimes would be really cool.
One idea could be a magic school set in a hidden dimension. The students could learn unique forms of magic like shadow manipulation or time - splicing magic. Another idea is a magic competition where the contestants have to use their magic to solve complex puzzles and overcome dangerous obstacles. And a third idea could be a group of magic users who are on a quest to find the origin of all magic, facing many challenges along the way.
Another interesting concept for a 'naruto magic fanfic' is to have Naruto travel to a parallel world where magic is the dominant power instead of chakra. In this world, he has to learn magic from scratch while also trying to find a way back to his own world. He could make new friends who are mages and together they could face the challenges of this new world.
Well, perhaps the 'arrow magic fanfic' could involve an ancient prophecy related to the arrows. A young hero is chosen to wield these magical arrows and must use them to defeat an evil sorcerer who is threatening the land. The arrows might have different magical abilities based on their fletching or the type of wood they are made from. For instance, arrows with eagle feathers could have the power of flight for a short time.
One idea could be to explore the lives of minor characters in the Harry Potter universe. For example, you could write about the backstory of Neville Longbottom's parents before they were tortured into insanity. Another idea is to create a new magical creature and describe its interaction with the known wizarding world. Maybe a creature that lives in the Forbidden Forest and has a special connection to the trees there.
One idea could be a fanfic where a character discovers a long - lost magic spell that can control the weather. This could have a huge impact on the power struggles in Westeros. For example, if a small house had this power, they could use it to their advantage during battles or to gain more influence.
One idea could be a character discovers a hidden magic within themselves that is connected to Aphmau's world. For example, they might find out they can control a special type of magic like shadow magic which is rare in the Aphmau universe. This could lead to a journey of self - discovery as they try to master it while also facing challenges from those who fear this new power.
One idea could be a team of underdog mages who use unorthodox magic to surprise everyone in the Grand Magic Games. For example, a mage who can control plants in a world where most magic is elemental.
One idea could be a new student arriving at the Anti Magic Academy with a mysterious power that no one has seen before. This power could either be a great asset or a source of fear among the students and faculty.
One idea could be that Harry discovers he has a unique magical ability that even Dumbledore doesn't know about. This ability could be related to his connection with the very essence of magic. For example, he might be able to communicate with magical creatures in a way no one else can, which leads him to uncover secrets about Hogwarts' past.
One idea could be that Harry discovers a new and powerful form of magic that was long forgotten. He then has to learn to control it while also hiding it from those who might misuse it.
