One common theme is the power struggle. Given that both Merlin and Vivien have magic, there's often a tug - of - war between their powers and how they use them in relation to each other. Another theme is love and betrayal. Their relationship can be a complex web of love, but also the potential for one to betray the other due to different loyalties. And of course, the theme of magic itself, exploring the different aspects of their magical abilities and how they combine or clash.
One great Merlin and Vivien fanfiction is 'The Enchanted Bond'. It delves into their relationship in a magical and mysterious way, exploring how their powers interact. Another is 'Vivien's Choice', which focuses on Vivien's perspective and her inner struggles regarding her feelings for Merlin. There's also 'Merlin and Vivien: A Different Path' that takes an alternate universe approach, showing what could have been if they had made different decisions.
In a more humorous take on the 'Merlin tied to a bed' fanfiction, it could be that Merlin has fallen ill and the overly - protective Gaius has tied him to the bed to make sure he rests. Merlin, being the active person he is, complains constantly. Arthur comes to visit and teases Merlin about finally being still for once. Meanwhile, Merlin tries to convince Arthur to let him loose, promising that he'll be fine. Eventually, Gaius relents and unties Merlin, who then immediately starts bustling around the room.
The 'vivien murder horror story' could be a complex narrative. It might start with Vivien living an ordinary life until she stumbles upon a dark secret. This secret could be related to a cult or a hidden criminal activity in her town. As she gets closer to uncovering the truth, the people involved in this dark matter decide to murder her to keep her silent. The murder could be described in a very gory and terrifying way, with the story then delving into the aftermath and how the mystery of her death slowly unfolds.
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.
One more idea is that Merlin is tied to the bed in a dream - like state created by an ancient magic. In this dream world, he is faced with his deepest fears and insecurities. His friends in the real world notice his strange behavior and try to wake him up. Merlin, while in the dream, has to find the source of the magic that is binding him and break free. Through his inner strength and the memories of his friends, he manages to do so and wakes up, having learned more about himself and his magic.
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.
