A plot idea could be that Jane and Alec get separated from the Volturi during a mission. They then have to find their way back while facing various challenges, like other vampire clans or even some human hunters who are aware of their existence. This would force them to rely on each other more than ever.
One interesting plot could be a time - travel fanfiction. Jane and Alec get sent back in time to a period before they became vampires. They have to deal with their human selves and the knowledge of what they will become. This could lead to some very complex character development as they try to change or accept their fates.
One plot idea could be that Alec and Seth are forced to team up against a new common enemy in the Twilight universe. Maybe a powerful vampire from a far - off land arrives and starts causing chaos. Alec, with his unique vampire abilities, and Seth, with his wolf - pack strength, have to put aside their differences and learn to work together. This could lead to some really interesting character development as they get to know each other better.
One idea could be that Jane and Demetri are sent on a secret mission by the Volturi. They have to infiltrate a group of vampires who are suspected of planning an uprising against the Volturi. Along the way, they start to question their loyalty to the Volturi as they see the other vampires' reasons for wanting change.
One possible fanfiction could be about Jane and Alec's early days as vampires in the Twilight universe. Maybe it could explore how they came to be part of the Volturi and their initial reactions to the power and the strict rules there.
Perhaps in the fanfiction, the dragon gets injured in a fight with a new, mysterious foe. Jane then has to journey far and wide to find a rare healing herb that only grows in a dangerous enchanted forest. Along the way, she meets various magical creatures who either help or hinder her mission.
Well, you could do a fanfiction where Jane has special powers. For example, she can communicate with animals. This would add a whole new dimension to her time at Thornfield. She could use her power to sense danger around the house. Or, perhaps a fanfiction where Rochester doesn't lose his sight and hand in the fire. How would their relationship develop differently? Also, a fanfiction set in an alternate universe where Thornfield is a magical place full of secrets and Jane has to use her wits to uncover them.
One plot idea could be that Jane and Gunther go on a quest together to find a rare herb that has the power to heal the dragon when it gets sick. They face various obstacles like a treacherous swamp and a mean - spirited forest spirit.
A plot could be that the Twilight vampires are mistaken for a new threat by the Avengers. So, there's a lot of misunderstanding and conflict at first. But then they realize that there is a real bad guy who is using their feud to his advantage. They then have to work together to take this villain down. Also, what if some of the Avengers become vampires or werewolves? How would that change their dynamic and abilities? For instance, if Captain America became a vampire, would his sense of justice remain the same? And how would his new powers interact with his old ones?
One interesting plot idea could be exploring the backstory of a minor character in more detail. For example, a side character who has a unique power but it was never fully explored in the original. Another could be a time - travel plot where a character goes back to change an important event in the Twilight Diaries universe. And also, a plot where characters from different factions have to team up against a new, unexpected threat.
One idea could be exploring what would happen if a new vampire with a unique power entered Forks. This new vampire could disrupt the existing relationships between the Cullens and the other characters in Twilight. For example, they might have a power that could temporarily nullify the abilities of other vampires, leading to some tense and interesting situations.
One plot idea could be exploring the backstory of the characters in the 'awoken twilight' world. Maybe there was a great war or a magical event that led to their current state. Another could be a love story between an awoken and a regular human, dealing with the challenges of their different existences.
