The role could be that of an outcast. People might shun her because of her father, and she has to find a way to survive on her own. This could lead to her becoming a rogue figure, making her own rules in a world that has no place for her.
Well, it could be about her trying to redeem the name of her father. Maybe she joins the Holy Grail War not for power but to prove that Mordred's line can be heroic. She might form alliances with some of the traditional heroes, like Saber, and they initially have a lot of mistrust but over time come to respect each other.
In an 'daughter of Mordred' OC fanfiction, she could be a complex character. Maybe she struggles with the dark legacy of her father. She might be on a journey to redeem the family name or she could be lured towards the same dark path Mordred once walked. For example, she could be in a world where the Arthurian legends are still very much alive in the background, and her actions are constantly judged in the light of her father's deeds.
She would probably have a complex relationship with the Arthurian characters. For example, with Artoria, there would be a lot of tension. Artoria might see her as a reminder of Mordred's betrayal. But the OC could also try to show Artoria that she is her own person. With other Servants like Archer, she might be initially seen as an enemy, but if she shows her good intentions, they could become allies.
One common theme is the struggle for identity. Mordred already has her own issues regarding her identity in the Fate series, and when an oc is introduced, it often adds another layer to this exploration. For example, an oc might be from a different background that challenges Mordred's views on herself and her place in the world.
One common theme is self - discovery. Both Mordred and the OC often go through a journey of understanding themselves better because of their relationship. Another theme is loyalty. They usually show great loyalty to each other in the face of various difficulties.
To write this type of fanfiction, you should focus on the relationship development. The fem OC could be from a different land, which adds an element of mystery. Research the Arthurian legends to add authenticity. For the relationship, start with a small moment of connection, like sharing a meal or a common view. Then, as they face challenges together, their bond deepens. Maybe there's a conflict where the fem OC has to choose between her loyalty to her homeland and her growing feelings for Mordred. This creates drama and keeps the readers engaged. Also, use vivid descriptions to bring the world and their relationship to life.
Well, in this fanfiction, perhaps Merlin adopts Mordred after Mordred is orphaned. Merlin realizes that Mordred doesn't have to follow the dark path that is foretold. So, he starts training Mordred not just in magic but also in values. They go on adventures, helping people in Camelot. Mordred begins to see Merlin as a father figure and they work towards a future where Camelot can accept Mordred as an ally, not an enemy.
She could be a mediator. Given the werewolf - vampire feud, Paul's daughter might be someone who can see both sides and try to bring about understanding. Maybe she has a more open - minded view because she's a new generation.
Love and friendship are also common themes. An OC could develop a deep friendship or even fall in love with Mordred. This relationship can be complicated by Mordred's status as a Servant and the events of the Holy Grail War. It can also be a source of character development for both the OC and Mordred. For instance, Mordred might learn about different forms of love and loyalty through her relationship with the OC, while the OC might grow in courage and determination as they get closer to Mordred.
One great fem OC x Mordred fanfiction is 'A New Destiny'. It has a well - developed fem OC who has an interesting dynamic with Mordred. The story dives into their adventures together in the Arthurian world, with great character interactions and a plot that keeps you hooked.
