The theme of forbidden love is also quite common. Since they might belong to different factions or have different loyalties in their story world, a love between them could be seen as forbidden. Writers often explore how they deal with this situation, whether they fight against it or give in to their feelings. It adds a lot of drama and tension to the fanfiction.
Some fanfictions also explore the theme of soulmates. They might be depicted as two halves of a whole, drawn to each other in a way that defies logic. This can lead to some really romantic and emotional stories, as they discover their deep connection and learn to trust and love each other completely.
One common theme is rivalry turned friendship. They start off as enemies but over time, in many fanfics, they learn to respect and even rely on each other.
Damon and Elijah's love story in fanfiction could be a story of two very different souls finding common ground. Damon, with his wild and often impulsive nature, might initially clash with Elijah's more refined and calculated demeanor. But as the story unfolds, they could discover that they both have a deep sense of loyalty and a longing for something more in life. They might start off as rivals, perhaps over a shared interest or a person, but gradually realize that their feelings for each other are much more complex and romantic. For example, in a small town setting, they might be forced to work together to protect the town from a common threat. During this time, they begin to see the good in each other and eventually fall in love.
One key element could be their different personalities. Damon's brashness and Elijah's elegance can create an interesting dynamic. Another is their loyalty to their own beliefs which can lead to conflicts and then reconciliations. Family also plays a part. Elijah's family ties and Damon's lack of such strong family bonds can be a point of connection and divergence. For instance, Elijah might introduce Damon to the concept of family loyalty in a positive way, and Damon could show Elijah how to break free from some of the more stifling family traditions. The setting, like a mysterious old town or a grand vampire mansion, can add to the mood of the love story.
One popular theme is the complex relationship between Elijah and Kol. In many fanfictions, they might be depicted as having a love - hate relationship, with their different personalities causing friction. Another theme could be their backstories and how they interact with other characters from their universe in new and unique ways. For example, their interactions with other vampires or supernatural beings in the story can add a lot of depth. Also, themes of redemption and power struggles are quite common. Kol might be shown as trying to gain more power and Elijah as trying to keep him in check, while also dealing with his own moral code.
