Wrath is one of the main characters. He is a strong and powerful leader in the Brotherhood.
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.
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.
Wrath is a very popular character. He's the king of the vampires and has a strong and complex personality. Another popular one is Butch. He's a human who gets involved with the Brotherhood in a very unique way.
One popular book could be 'Lover Awakened'. It has a great story with complex characters. The intense relationships between the characters really draw readers in.
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.
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.
The novels usually have a richly developed supernatural world, complex characters with deep backstories, and intense romantic plots.
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 main event is his discovery of his true identity within the Brotherhood. Another is his training to become a more effective fighter against their enemies.
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.
