A different plot could be about a power struggle within the Brotherhood. There could be a group of members who think the current leadership is too soft on dealing with the enemies. This could lead to internal conflicts, with some members trying to overthrow the current leaders while still having to face the external threats to their kind.
An OC who is a vampire from a different clan and has different cultural values. This OC could bring new perspectives to the Black Dagger Brotherhood, challenging their traditional ways and leading to some internal conflicts as well as growth for the group.
Fanfictions that focus on the training regimes of the Brotherhood can also be really engaging. They can detail the intense physical and mental training that the warriors go through. This not only gives readers a better understanding of how the characters become so strong and skilled but also adds an element of action and adventure to the story.
The complex characters are a great aspect. Each brother in the Black Dagger Brotherhood has a unique backstory and personality. Their relationships, both within the brotherhood and with the outside world, add depth to the stories.
One interesting story could be about the intense brotherhood bonds among the characters. Maybe a story where they face a great external threat together and how their loyalty to each other is tested and prevails.
Maybe there's a plot where the cloak and dagger are not just physical objects but hold some sort of ancient ninja magic. Naruto discovers that the cloak can make him invisible in certain conditions and the dagger can cut through any kind of barrier. He has to figure out how to master this magic to save the village from a new threat.
Wrath is often a very popular character in fanfic. As the king, he has a lot of power and responsibility, which makes for interesting storylines. His relationship with Beth is also a big draw, and many fanfics explore different aspects of their relationship, like how they deal with ruling together.
In Vishous - centered fanfics, Marissa can be an interesting character to pair with him. Given her own story arc in the Black Dagger Brotherhood world, when combined with Vishous, it can create some really engaging storylines. For example, their different personalities and backgrounds can lead to some great character - driven plots. Also, Payne can be an interesting pairing. Their shared heritage and her own unique abilities can add a new dimension to their relationship in fanfics.
One idea could be to explore the backstories of the avatars in the brotherhood. Maybe they all come from different worlds or cultures and how they came together to form the brotherhood. Another could be a story about a new avatar joining the brotherhood and facing challenges to be accepted.
One of the main themes is loyalty. The Brotherhood members are extremely loyal to each other in their fight against the Lessening Society. Another theme is love and sacrifice. We often see characters sacrificing their own well - being for the sake of their loved ones or the greater good within the vampire society depicted in the novels.
The novels usually have a richly developed supernatural world, complex characters with deep backstories, and intense romantic plots.
