One great female Merlin fanfic could be one where she uses her magic in unique ways to save Camelot. For example, in a story she might use her powers to heal the knights secretly when they are injured in battle. This would add an interesting twist as she has to hide her actions from Uther.
If Merlin died in the fanfiction, it could trigger a series of tragic events. The balance of power could tip, and the villains might seize the opportunity to attack. It could also bring out hidden strengths in the remaining characters as they try to cope with the loss.
If Merlin is a Dark Lord in fanfiction, it could be an interesting exploration of the 'nature vs. nurture' concept. Maybe he turned dark because of the constant fear of being discovered and persecuted for his magic. His actions as a Dark Lord might include taking over Camelot or exacting revenge on those who wronged him in the past. It gives a whole new perspective on his character.
Perhaps some of the snooty nobles who look down on Merlin and constantly try to get him into trouble. They could be making fun of his clumsy ways one too many times and he just snaps and hits them with a shoe. It would be a moment of satisfaction for the readers who don't like those arrogant characters.
One possible secret could be that Merlin is a powerful sorcerer from an ancient and powerful magical lineage. Maybe his family has a long - standing connection to Camelot that has been kept hidden.
Maybe in the fanfiction, Uther discovers the creativity and the different perspectives on his world and characters, and he sees value in it. He might be a more open - minded version of himself in the fan - created stories.
In Merlin fanfiction, Merlin might tell a story about his magic origins. Maybe he shares how he discovered his powers as a young boy in Ealdor. He could talk about the first time he made something extraordinary happen, like making a flower bloom in the dead of winter. This story would not only be about his powers but also about the fear and wonder he felt at that moment.
A sense of adventure would be in Merlin's story. He has been on many quests and journeys. He might talk about traveling to far - off lands in search of a solution to a problem in Camelot. He could describe the different landscapes he saw, from snow - covered mountains to vast deserts. And of course, there would be elements of good versus evil, as Merlin constantly battles against the forces of darkness to protect the light in Camelot.
