What could be the possible plot of a 'kept in the dark' Vampire Diaries fanfiction?

Maybe an amnesiac character. They've lost their memories and don't remember anything about the vampires and other supernatural beings. They are the perfect candidate to be kept in the dark as they have no prior knowledge to start with. Their journey to regain their memories and discover the truth about the Vampire Diaries world could be the main plot.

One possible plotline could be that Tatia's sister is a long - lost relative who suddenly shows up in Mystic Falls. She might have some hidden powers or knowledge about the vampire - werewolf - witch triangle that the main characters are unaware of, and this knowledge could either help or hinder them in their battles.

One possible plot could be that the Avengers are investigating a series of strange disappearances in a small town. They soon discover that vampires from The Vampire Diaries' world are behind it. There could be a face - off between Thor's hammer and the super - strength of some of the older vampires. Maybe Damon could team up with Iron Man, with their shared sarcastic sense of humor, to outwit the main villain who is causing chaos in both their worlds.

One possible motive could be protection. Maybe Damon senses a danger approaching the reader and biting them is his way of marking them as under his protection. In the vampire world, a bite can be a sign of claiming someone.

Another possibility is that she was poisoned. There could be a new type of poison in the 'Vampire Diaries' world that affects vampires in a deadly way. And Caroline, being a vampire, was unable to resist it. Or, it could be related to the ongoing power struggles between different vampire factions. She might have been caught in the middle and killed as a result.

Since I haven't read this particular fanfiction, it's hard to say. But it might revolve around a character who was previously unimportant or unseen in the show. Maybe it gives them a more central role, perhaps a new love interest for one of the main characters or a new mystery related to their origin.

Another possible plotline is that Valerie and Stefan discover a hidden prophecy that links their fates together. They then have to work together to fulfill the prophecy or prevent it from coming true. Along the way, they face numerous obstacles and their relationship is put to the test. Their journey could take them to different magical realms or involve battles with powerful supernatural beings.

Perhaps the pregnancy could be a sign of a greater prophecy in the Vampire Diaries fanfiction world. Caroline might be seen as a key figure in a new chapter of the supernatural world. Her pregnancy could bring about a new era where vampires, witches, and werewolves have to come together to protect her and the baby from an ancient evil that has awakened due to this new life on the way.

One popular theme is alternative universes (AUs). For example, stories where the characters are in a modern - day high school but with a supernatural twist different from the show. Another is character relationships. Fans often explore different pairings, like Damon and Bonnie, which might not be as prominent in the original series. And there are also time - travel themed fanfics, where characters go back in time to change certain events in the Vampire Diaries timeline.

One possible plot could be that Caroline's brother discovers he has a special power that the vampires in Mystic Falls want to use for their own gain. He has to learn to control this power while also dealing with the danger of being hunted by the vampires.
