One common theme is his struggle with his inner demons. In the Black Dagger Brotherhood world, Vishous has a complex past and personality. Fanfics often explore how he copes with his gifts and curses. Another theme could be his relationships, whether it's his brotherly bonds within the Brotherhood or his romantic involvements. His role as a protector is also a theme, as he uses his unique abilities to safeguard those he cares about.
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.
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.
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.
Rhage is also important. He has a beast within him, which makes his character both dangerous and endearing. His relationship with Mary is a significant part of the story.
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.
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.
It's possible that there are characters who have a special connection to the origin or the lore of the brotherhood. These characters could play important roles in the short stories, perhaps as the ones who pass on the traditions or as the ones who hold the key to solving major problems that the brotherhood faces.
