Perhaps it delves into the idea of different cultures' magic co - existing. The Gate of Babylon comes from a very different cultural and mythological background compared to the Western - based magic in Harry Potter. So, the fanfiction could show how the characters in Harry Potter react to and adapt to this new, foreign type of magic. It might also involve crossovers where characters from the Potter world have to team up with characters associated with the Gate of Babylon to face a common threat, like a dark force that can only be defeated by combining both types of magic.
One interesting concept could be the unique character creations. In OC (Original Character) fanfictions, the new characters often bring fresh perspectives. They might have distinct abilities related to the Gate of Babylon, like perhaps a new way of summoning or using the treasures within. Another concept could be alternative storylines. Instead of following the main plot strictly, it could explore what would happen if certain events in the Gate of Babylon's lore occurred differently. For example, different power dynamics among the characters due to the use of the Gate of Babylon.
One interesting concept could be the combination of Naruto's world with the Gate of Babylon's abilities. For example, how Naruto characters might interact with the treasures from the Gate of Babylon. It could lead to unique battle scenarios where Naruto's jutsu and the powerful artifacts from the Gate collide.
In a fanfiction scenario, the Gate of Babylon could be a hidden power within Hogwarts that Harry Potter uncovers. This power might be related to the ancient magic that the founders of Hogwarts once dabbled in. As Harry explores this new aspect of magic, he realizes that the Gate of Babylon can summon all sorts of magical artifacts. He could use these artifacts to upgrade the defenses of Hogwarts, like creating impenetrable shields or powerful wards. At the same time, he might face opposition from some in the wizarding world who fear this new and unknown power. But Harry, being the hero, would find a way to balance the power of the Gate of Babylon with the traditional magic of the wizarding world to protect everyone from Voldemort's threats.
Hermione might also be a main character. Given her thirst for knowledge and her ability to research, she could be the one to dig deeper into the mysteries of the Gate of Babylon and how it relates to their magic. Maybe she finds ancient texts in the Hogwarts library that hint at the existence of the Gate of Babylon and its significance in their world.
One interesting crossover could be Naruto learning about the Gate of Babylon's treasures and trying to incorporate them into his jutsu. For example, he might use some of the powerful weapons from the Gate of Babylon as a way to enhance his Rasengan, creating a more powerful and unique attack. Another aspect could be a battle between Naruto and an enemy where the Gate of Babylon's abilities are pitted against Naruto's ninja skills. It would be a clash of two very different power systems, making for an exciting read.
In this type of fanfiction, the concept of advanced humanity could also mean a change in human values. Perhaps humans have become more empathetic and understanding on a global scale. This could be shown through their interactions with other species, where they are more willing to make sacrifices for the greater good. It could also be reflected in how they treat their own kind, with less discrimination and more cooperation. For instance, in the story, a character might be from a previously marginalized group on Earth but now is a key figure in inter - galactic relations because of the shift in human values.
One interesting concept could be exploring more about the Marauders' time at Hogwarts. Fanfiction might expand on their adventures, like pranks they played that were never mentioned in the original book. Another could be different interpretations of Sirius Black's escape and his relationship with Harry during that time.
Some fanfictions in Harry Potter 2 might play with the idea of the basilisk having different powers or weaknesses. It could also explore the idea of a hidden connection between Ginny and the Chamber of Secrets that goes beyond what was in the original story. There might be fanfictions that change the role of certain characters, like making Neville a more central figure in solving the mystery of the Chamber.
One interesting concept could be exploring new magical creatures in the Harry Potter kingdom. Maybe there are some hidden species that haven't been discovered in the original series. Another could be alternative forms of magic that are unique to the fanfiction's version of the kingdom. And also, new relationships between different houses or characters can be quite fascinating.
One interesting concept could be the use of magic in relation to physical laws. For example, how spells might interact with gravity. Maybe a levitation spell actually counteracts the force of gravity in a way that can be explained through some made - up 'physics' in the fanfiction.
