The plot might also be about a threat to the kingdom. As king, Gwaine has to lead the defense, and with Merlin as his partner, they use magic and strategic thinking. Their marriage is not just a love story but also a partnership in ruling. They might face an ancient evil that only Merlin's magic can defeat. Along the way, they'd grow closer, and their relationship would be tested and strengthened as they save the kingdom.
One great fanfiction could be where Gwaine, as king, has to navigate the political waters while being married to Merlin. Their relationship might bring about new laws that are more inclusive and magical - friendly in the kingdom. Maybe Merlin uses his magic secretly to help Gwaine make the best decisions for their people.
Love and loyalty are always big themes. Their deep love for each other is explored, how they stay loyal through thick and thin. In some fanfictions, there's a theme of sacrifice, where one of them might be willing to sacrifice something important for the other's well - being. And cultural differences between them can also be a theme, as they come from different backgrounds, and how they bridge those gaps in their relationship.
Friendship is a very common theme. Their bond is often explored, like how they trust each other unconditionally. For example, in many fanfictions, Gwaine will always have Merlin's back in dangerous situations.
Well, in fanfiction, Merlin and Gwaine's friendship is really cool. Gwaine is the kind of friend who's always up for an adventure with Merlin. He's not afraid to get into trouble right beside him. They have a great dynamic where Gwaine can be a bit more carefree and Merlin is sometimes more cautious, but they balance each other out. Their friendship also gives Merlin someone he can really trust outside of Arthur. Gwaine doesn't judge Merlin for his secrets and is always there to have his back, which is a really important aspect of their relationship in the fanfictions.
Some people also share fanfictions on Twitter. Search for Merlin and Gwaine related hashtags along with 'fanfiction' or'married'. However, the content on Twitter might be more scattered compared to dedicated fanfiction platforms. You may need to dig deeper and look for threads or accounts that are known for sharing Merlin fan works.
Well, one possibility is that Merlin uses his magic secretly to gain the support of the people. He might perform great feats during times of crisis, like saving the kingdom from a powerful enemy. And then, through a series of events, the nobles and commoners alike start to see him as a true leader and he is finally crowned king.
A plot could involve Merlin and Freya getting married in secret. Then, as they start their new life together, they discover that Freya has a special connection to a hidden realm. They must work together to protect this realm from dark forces that are trying to invade it. Their married life becomes a series of adventures as they fight side by side, using their combined magic to keep the realm safe.
Well, Gwaine might decide to help Merlin protect Aithusa. He's a loyal friend, so he could offer to stand guard or find a safe place for the dragon.
A good Gwaine and Merlin friendship fanfiction should have strong characterizations. It needs to capture Gwaine's roguish charm and his loyalty, as well as Merlin's kind heart and the burden of his secret magic. For example, if Gwaine is written out of character as being too serious all the time, it won't feel right.
Another theme is loyalty. They are loyal to Camelot and to each other. In many stories, this loyalty is tested, for example, when they have to choose between following the rules of Camelot and doing what they think is right. It makes for some really interesting plotlines. And often, there's also the theme of adventure. They might go on quests, fight monsters, or discover new magical things, which adds a lot of excitement to the stories.
