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, it could start with Merlin finding Freya in a difficult situation. Maybe she's being chased by some dark forces. Merlin uses his magic to save her and in that moment of relief and gratitude, they share a kiss. It could be a very tender and innocent kiss, filled with the start of new feelings between them.
Well, perhaps Merlin would plan an elaborate, magical proposal. He might use his magic to create a beautiful, enchanted garden filled with Freya's favorite flowers and glowing orbs of light. Then, in the center of this magical place, he'd get down on one knee and present her with a ring made from a rare, enchanted gemstone that has special meaning to them both.
A plot for a Merlin and Freya pregnancy fanfic could involve a magical pregnancy. Since Merlin has magic and Freya has her own unique abilities, the pregnancy could be anything but ordinary. There could be signs and omens that the baby is destined for something great. They might have to protect the unborn child from dark forces that sense its potential power. The story could show how they work together to keep the baby safe. It could also include some tender moments where they talk to the baby in the womb, sharing their hopes and dreams for its future.
Well, a plot twist might be that Freya discovers she's pregnant with a special kind of magic - not just normal magic but something that is a blend of different magical realms. This causes a stir in the magical community and they have to deal with the politics and jealousy that comes with it. Also, Merlin might have to hide this fact from Arthur for a while as he fears Arthur's reaction to such a strange magical occurrence.
She might be completely overjoyed. With tears of happiness in her eyes, she'd immediately say yes and throw her arms around Merlin. After all, she loves him deeply and has probably been waiting for this moment.
Love is a very common theme. Their relationship, whether it's a budding romance or a deep platonic bond, is often explored. Another theme is magic. Since both are magic - related characters, how their magic interacts or complements each other is frequently written about.
One major theme is sacrifice. Given their circumstances in the show, many fanfictions show either Merlin or Freya sacrificing something for the other. For example, Merlin might sacrifice his safety to protect Freya. Also, the theme of redemption can be found. If Freya was seen as having a 'dark' side in some interpretations, fanfictions may explore her journey of redemption with Merlin by her side. And of course, the theme of adventure is also common as they go on various quests in these fictional stories.
One possible plot twist could be that the elf has a hidden magical power that Merlin doesn't know about. This power could either help them in their adventures or cause some problems in their relationship. For example, it might attract the wrong kind of attention from other magical beings. Another plot twist could be that Merlin discovers that the elf is part of a prophecy that he was unaware of. This could change the whole dynamic of their relationship as they now have to deal with the implications of the prophecy.
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.
Their relationship would become more intertwined with their daily lives. They would have to make decisions together, like where to live. Maybe they would choose a place that is in between their two magical worlds. Also, they would start to think about the future in a more long - term way, such as planning to have children and how to raise them with both of their magical heritages.
