One idea could be that Merlin has to hide his magic even on his wedding day to Arthur. Maybe there are some old enemies who try to disrupt the wedding, and Merlin uses his magic subtly to protect everyone without being detected. Another plot could involve Arthur trying to incorporate some of Merlin's commoner traditions into the grand royal wedding, causing some comical and heartwarming moments among the nobility.
Their different backgrounds can create a lot of drama and charm. Merlin's background as a servant means he is used to hard work and frugality. So when it comes to the wedding, he might be more hands - on with the preparations, doing things like making flower arrangements himself. Arthur, being a prince, has grown up with servants doing everything for him. He might initially be a bit clueless about the practicalities. But as they plan the wedding, they both learn from each other. Merlin learns about the grandeur and significance of a royal wedding, and Arthur discovers the beauty and simplicity of a commoner's approach to such an event.
Their wedding would be a grand affair. It might be held in Camelot's grand hall, filled with knights, nobles, and common folk alike. Arthur would surely wear his finest armor, polished to a shine, while Merlin would don a simple yet elegant robe. There would be feasting for days, with music and dancing. The vows they exchange would be a blend of the traditional and the deeply personal, pledging their love and loyalty to each other in front of all their friends and subjects.
The banter between Merlin and Arthur in fanfiction is really interesting. It can range from light - hearted jabs at each other's habits. Merlin might poke fun at Arthur's love for jousting and how he always gets a bit too competitive. Arthur could retort by mentioning Merlin's clumsy attempts at serving him. Their banter also reflects the underlying respect they have for each other despite their different social standings. It's like a friendly sparring that keeps their relationship dynamic.
In the story, Merlin was a powerful wizard who played a crucial role in Arthur's life. He guided Arthur from his early days, often using his magical powers to protect him and ensure he could fulfill his destiny as king. For example, he arranged for Arthur to pull the sword from the stone, which was a key moment in Arthur becoming king. Merlin also provided wisdom and counsel to Arthur throughout his reign, helping him make important decisions.
Merlin would likely be seen as a bit of an enigma at Hogwarts. His magic is different from the norm, so he might be a bit of an outsider at first. But his kind heart and loyalty would soon win over his classmates. Arthur would be the brave and headstrong character, perhaps a bit like a Gryffindor version of his usual self. He'd be eager to learn about combat magic and would probably be a natural leader in group projects or Quidditch teams.
During the time of Merlin's captivity, they could have long conversations that they never had before. Arthur might open up about his insecurities regarding magic and his kingdom, and Merlin could share his true feelings about serving Arthur. This would strengthen their bond in a new and unexpected way.
It could start with a slow realization of their feelings. Maybe they were friends for a long time and then suddenly, one day, they look at each other in a new light. After getting married, they become more protective of each other. Arthur might become more open to Merlin's magic, and Merlin would be more involved in Arthur's political decisions.
The 'Redemption' trope is also seen in some fanfictions. Maybe Arthur has made some mistakes in the past, and Merlin helps him to redeem himself. Or vice versa. It's a way to explore the characters' growth and development. And then there's the 'Battle Against Evil' trope where they fight side by side against dark forces, which really showcases their bond and loyalty.
