It might be to explore the idea of fate in a different way. If Merlin is Mordred's father, it could change how their fates are intertwined. Also, it can create a more personal conflict for Merlin. He has to face the fact that his own son could be the cause of the downfall of Camelot, which adds a lot of drama to the story.
One reason could be to add a new twist to the story. It makes the relationship between Merlin and Mordred more complex and emotional.
Yes, in some fanfictions, Merlin is written as Mordred's father. Writers often like to explore different family relationships and backstories in fanfiction, and this is one such interesting take on their relationship.
One reason could be that it doesn't have the right format recognition for fanfiction. Fanfiction can have unique formatting styles that are different from regular texts, and Merlin might not be programmed to handle those.
It could also be due to the lack of proper rest. Merlin is usually depicted as a very busy character in fanfiction. He has duties in the castle, like serving Arthur, and on top of that, he has to use his magic to help those in need secretly. With so much to do, he might not have enough time to rest, leading to exhaustion.
One reason could be his sense of isolation. In many fanfictions, Merlin might feel alone as he has to keep his magic a secret from most people around him. This constant hiding and fear of discovery can lead to depression.
The themes could include redemption. Maybe Mordred worships Merlin as a way to atone for his own actions or the actions of his kind. It could also involve the theme of power dynamics. Since Merlin is a powerful figure, Mordred's worship could be related to his awe of Merlin's power. Additionally, there could be a theme of unrequited love, where Mordred's worship has an undertone of romantic love that Merlin may not reciprocate.
It could be a case of misinformation. Someone in the story might have spread false rumors about Harry being the father for their own motives. Perhaps they wanted to cause chaos or gain something from the situation. So, the whole idea of Harry being the father is just a false story that gets spread around the wizarding community.
One reason could be the strong bond between them in the original story. Fans might have felt that it could be developed into a father - son relationship in fanfic.
The possible reasons are numerous. For starters, fans might be interested in exploring the idea of how two very different characters like Snape and Hermione could be related. It could also be a way to give Hermione a more mysterious origin. Since Snape has such a complex and often misunderstood character in the original series, tying him to Hermione in this way can create interesting storylines. Additionally, it might be a form of wish - fulfillment for some fans who want to see a different kind of family structure in the Harry Potter universe.
In some fanfictions, there could be a plot where Merlin, as a female, uses her magic to protect Mordred from the threats in Camelot. This protection gradually turns into a deep emotional and physical connection. The 'lemon' aspect might come in when they finally give in to their desires during a time of crisis or celebration. But we should also remember that these are just fictional interpretations and often deviate from the more traditional versions of the Merlin and Mordred story.
One common theme is redemption. Often, Mordred is shown as a character who has the potential for good despite his fated role in the Arthurian legend. Merlin is sometimes the catalyst for this redemption. For example, in many fanfics, Merlin tries to change Mordred's path towards the doom he is supposed to bring.
