Another unique theme is the alternate timelines. Fanfictions might show what would have happened if certain events in the show had been different. For instance, if Morgana had known about Merlin's magic earlier, how would their relationship and the whole story arc have changed? This allows for a lot of creativity and different interpretations of the characters.
One unique theme is the exploration of their relationship beyond the typical good - vs - evil dynamic. In some fanfics, they find common ground based on their shared experiences with magic, which is really interesting.
Redemption is also a common theme. Since Morgana often takes a darker path in the original, many fanfictions explore the possibility of her redemption, with Merlin being a key factor in that journey. Love, in various forms, is another theme. It could be a platonic love born out of mutual understanding or a more romantic love that defies the odds.
Well, power and control are major themes. Morgana's control over Merlin as a slave sets up a situation where power is constantly being negotiated. Also, themes of redemption can be present. Maybe Morgana realizes the wrongness of her actions and tries to make amends. And there's often a theme of secrecy too. Merlin might have to keep his true self and his magic a secret while being a slave, which adds to the tension.
A prevalent theme is the exploration of 'what if' scenarios. What if Merlin had revealed his magic to Morgana earlier? What if Morgana hadn't turned evil? These questions drive many 'Merlin loves Morgana' fanfictions. Additionally, the theme of sacrifice might come up. For instance, Merlin might be willing to sacrifice his relationship with Arthur or his standing in Camelot to be with Morgana.
Another theme is the power of love to change. In many fanfictions, their love has the potential to either redeem Morgana from her dark path or make Merlin question his loyalties. It's about how love can be a catalyst for personal and political change within the context of the magical world they inhabit. This is often explored through their interactions and the decisions they make based on their feelings for each other.
The theme of a dark destiny also runs through many 'Dark Merlin Morgana' fanfictions. It's about how their actions, when they embrace the dark side, lead them on a path that is different from the traditional heroic or 'good' destinies. It often involves them trying to reshape the world according to their dark ideals, which can be both fascinating and terrifying to read about.
One common theme is redemption. Morgana, in the role of a slave, often has a chance at redemption through her relationship with Merlin. Another theme is power struggle. Since Morgana has been in a position of power before, her new status as a slave creates an interesting power dynamic with Merlin.
A frequent theme is the transformation of their relationship. They usually start as adversaries or at least with a lot of tension between them. But once they get married in the fanfiction, they become partners. Also, the theme of acceptance is common. They have to accept each other's flaws and powers. In some stories, they also have to make the people of Camelot accept their relationship, which adds to the drama.
One common theme is power struggle. Since all three characters have magic, their fight for power, either to rule Camelot or to use magic freely, is often explored. For example, in many fanfictions, Morgana and Morgause team up to gain power over Camelot, and Merlin tries to stop them.
One common theme is the idea of defying fate. In the original Arthurian lore, their paths were set on different, often opposing, courses. So in these fanfictions, their marriage represents a break from the pre - determined destinies. Another theme is power - sharing. Since both are magically gifted, their union can mean a new balance of power in Camelot.
One popular theme is their mentorship - like relationship. Since Merlin has great magical power and knowledge, he could potentially be a mentor to Morgana, guiding her in understanding and controlling her powers. Another theme is their alliance against the dark forces in Camelot. They both have strong magic and could join forces to protect the kingdom.
