One possible fanfiction could revolve around Merlin's twin sister Marayana having unique magical abilities that set her apart from Merlin. Maybe she has a special connection to an element, like water, and uses it to protect Camelot in her own way. She could also have a different relationship with the main characters. For example, she might be closer to Morgana in the beginning, seeing the good in her before Morgana turns dark.
In a Marayana fanfiction, she could be the key to a prophecy that Merlin is also part of. Their twin bond gives them the power to defeat a great evil that threatens Camelot. Marayana might struggle with her identity as a sorcerer in a world that fears magic, just like Merlin. But her approach could be more diplomatic, trying to bridge the gap between those with magic and those without through her kind nature.
Marayana could be a healer in the fanfiction. She uses her magic to tend to the sick and injured in Camelot, which earns her the respect and love of the common people. This also makes her a target for those who oppose magic, as they see her as a threat to their anti - magic stance.
One possible story could be about the good twin having to face the challenges caused by the evil twin's actions. For example, the good twin might be constantly trying to clean up the messes the evil twin makes in Camelot. Maybe the evil twin is secretly working with Morgana to bring down King Arthur, while the good twin is trying to protect the king. This creates a lot of drama and conflict within the fanfiction world.
One common theme is the bond between siblings. Since they are twins, their connection is often portrayed as very strong, and they rely on each other in different situations.
One great Merlin twin sister fanfiction is 'The Twin's Destiny'. It explores the relationship between Merlin and his twin sister in a world full of magic and mystery. Their adventures together are really exciting.
One great aspect of Merlin - Arthur fanfiction is the exploration of their deep friendship. Writers often delve into the unspoken bond between them. For example, in some fics, they face new magical threats together that weren't in the original series. This allows for a fresh take on their characters as they rely on each other more than ever.
In some fanfictions, Prince Merlin (assuming he has some sort of princely status in this AU) and Morgana might be forced into an alliance against a common enemy. Maybe an ancient evil that threatens Camelot in a way that neither of them can face alone. They would have to put aside their differences and work together, which could lead to a slow - burning romance.
One great fanfiction in this area could be about Merlin's training in a secret magical realm. He might learn new spells and techniques from ancient magical beings that no one in Camelot has ever heard of.
There could be a fanfiction where Issei is a descendant of Merlin that is filled with all sorts of magical elements. Maybe Issei inherits Merlin's powerful magic and uses it to fight against dark forces. He could have the ability to perform great spells and manipulate the elements just like Merlin was known for in the legends.
A fanfiction could focus on the relationship between Mordred and Morgana. It could explore how Mordred came to be so loyal to Morgana in the first place. Was it out of fear, admiration, or something else? And how does Merlin fit into this complex dynamic? He might be seen as an outsider trying to break their bond.
One great aspect of Uther Pendragon and Merlin fanfiction is the exploration of their complex relationship. In the original series, Uther is often at odds with Merlin's magic, but in fanfiction, authors can reimagine their dynamic. For example, some stories might have Uther discover Merlin's magic earlier and instead of persecuting him, learn to accept it due to Merlin's selfless use of magic for the good of Camelot.
