One popular theme is the crossover of magic and modern - day detective work. Since Castle is a detective show and Merlin is all about magic, seeing how they blend together in different scenarios is really interesting to readers.
Friendship is also a big theme. Fans like to explore how Castle and Merlin would become friends, what kind of bond they would form, and how they would support each other in their respective quests, whether it's solving a crime or saving Camelot.
The exploration of different worlds is another common theme. Some fanfictions focus on what would happen if the characters from Castle visited Camelot, or vice versa. This allows for a lot of creativity in terms of world - building and character interactions.
One popular theme is the clash of magic. The Green Knight has his own brand of magic or otherworldly power, and when it meets Merlin's magic, it creates interesting scenarios. For example, in many fanfics, they have magical duels or exchanges of power.
Power is a theme that can't be ignored. The idea of power, whether it's the power of the castle in the sky or Merlin's own power, is often played with. Some fanfictions might show Merlin struggling with the power he encounters in the castle, or how he uses his own power to protect or uncover the secrets of the castle. It can also be about the power dynamics between different characters as they interact with the castle in the sky.
The ruling class or the nobles associated with the castle would be in big trouble. Their power base would be gone. They might try to hunt Merlin down or they could be forced to seek shelter and help from other lords. This would cause a shift in the power dynamics in the region.
Well, there are themes like Merlin's submissive friendship. He is often in a position where he doesn't assert himself fully in his relationship with Arthur. He takes on a submissive role to keep the friendship going, like when Arthur makes decisions that Merlin may not fully agree with but he still goes along. And then there's the theme of his submissive attitude towards the court. He's constantly having to be careful not to show his true self and is submissive to the power dynamics within Camelot's court.
Often, the theme of Merlin regaining his lost power or finding new ways to use his magic in his'reborn' state is explored. This can involve him having to learn magic all over again in a different magical environment. It might also include themes like redemption, where he tries to right the wrongs that happened in his past life, like finally fulfilling the prophecy of bringing back the Golden Age that he and Arthur were supposed to create.
One popular theme is the mentorship between Merlin and the child. It shows how Merlin imparts his wisdom and magic skills. Another is adventure, like the child and Merlin going on a quest to save Camelot. Also, the discovery of the child's own magical abilities with Merlin's help is a common theme.
One common theme is crossovers. Writers like to imagine how the characters from Smallville and Merlin would interact if they were in the same universe. Another theme could be character development. For example, showing how a character from Smallville might grow in the magical world of Merlin, or vice versa. And then there are the friendship themes, exploring how characters from the two shows could become friends and support each other through different challenges.
Well, a common theme is Merlin's growth as a wizard within the AOC setting. This can involve him learning new spells and facing challenges that test his magical abilities. Also, his role in the political and social aspects of the AOC world is often explored. For example, how he might influence the court with his magic and wisdom.
Another theme is Merlin's magic and how he hides it or uses it to save the day. There are also fanfictions that focus on Merlin's backstory, like his life before coming to Camelot and his family.
One popular theme is the exploration of Jethro Merlin's backstory. Fans are often interested in how he became the character he is, so they write stories that delve into his past, his family, and his early experiences.
