In fanfiction, Francis and Mary could face a magical threat together. Maybe a sorcerer has cast a spell on the kingdom, and they have to work together using their wits and courage. This would not only test their love but also show how they support each other in difficult times. It could lead to some really interesting character development and romantic moments as they rely on each other to save the kingdom.
A possible plot idea is that the baby is born prematurely. Mary and Francis are worried about the baby's survival. They turn to their most trusted advisors and physicians, but there are also those who see this as a sign of weakness in the monarchy. Meanwhile, there could be an enemy lurking in the shadows, planning to use the baby's fragile state to their advantage. As Mary and Francis fight to protect their baby, they also have to deal with the internal politics and power struggles within the court.
Around the baby, Mary and Francis's relationship could change in many ways. They may become more protective of each other as they are now a family. Their relationship with their servants might also be affected. The servants who take care of the baby could become like family to them. Francis might become more understanding of Mary's insecurities as a mother, and Mary could see Francis in a new light as a father. Their relationship with the court could also be influenced. Some in the court might try to use the baby for their own political gain, which would force Mary and Francis to stand united against such threats.
In 'Reign', Francis and Mary had a complex relationship. Francis was initially hesitant about their arranged marriage but grew to love Mary. For fanfiction, one could explore their early days, like how they first started to understand each other's personalities. Maybe a scene where they share a private moment in the garden, talking about their hopes for the kingdom and gradually realizing their feelings for one another.
Another plot might involve the baby having some sort of special gift or ability. This could bring both wonder and danger into their lives as they try to protect the baby from those who might want to use or harm it. For example, the baby could have an uncanny ability to predict events, which gets noticed by the wrong people.
Love and romance are common. Often, the OC will fall in love with Francis or be involved in a love triangle within the court. For example, in many stories, the OC might be a rival to Mary for Francis's affections.
The most common themes include love, of course. Their love story is what attracts many fans to write about them. Then there's the theme of royalty and court life. Since they were part of the royal court, fanfictions often depict the grandeur and the politics of the court. For example, how they had to maintain appearances while dealing with their personal feelings. There's also the theme of friendship. They were not only lovers but also friends, and fanfictions might explore this aspect, like how they supported each other as friends in difficult times.
There's also 'A Stranger in Reign's World' which focuses on an OC who has unique skills and knowledge from a different land. This OC gets involved with Francis in a rather unexpected way, adding new twists to the relationships and events we know from the 'Reign' series. The story is well - written, with detailed descriptions of the court life and the interactions between the characters.
Often, there might be themes related to relationships. For example, how her pregnancy affects her relationship with Francis or other important characters in the 'Reign' series. It could also explore how she copes with the physical and emotional changes while still being a queen, so themes of power and motherhood might be intertwined.
