There are also brotherhood fanfics in the superhero genre. Take the Batman and Robin relationship. Some fanfics delve into their brotherly connection beyond just the crime - fighting aspect, like how they support each other through personal struggles.
Growth is also a prevalent theme. As the story progresses, Piper and his brothers might grow as individuals and as a unit. They could learn new skills or gain more wisdom, all while their brotherly bond deepens and evolves.
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 possible fanfic could be about Brynjolf meeting the Dragonborn who is wearing the Dark Brotherhood Armor. Maybe the Dragonborn is on a secret mission related to the Dark Brotherhood, and Brynjolf gets caught up in it. They could form an unlikely alliance to face the challenges that come their way, with the unique powers of the Dragonborn and Brynjolf's skills in thievery and combat complementing each other.
First, decide on the characters that will form the brotherhood. It could be existing characters from a franchise or your own original creations. Then, think about the setting. A post - apocalyptic world can create a great backdrop for a strong brotherhood to develop as they rely on each other to survive.
One interesting aspect could be the exploration of the deep bond among the BTS members in a fictional way. It might show their friendship growing through different challenges and adventures that the writer imagines for them.
One popular theme is the exploration of the characters' backstories. For example, there are many fanfics that delve deeper into Edward and Alphonse's childhood before the alchemy incident.
To start a brotherhood avatar fanfic, you need to do some research if there are existing canons related to it. Then, start with an interesting hook, like a mysterious event that involves the avatars. Develop your characters gradually as you write. You can also add sub - plots to make the story more engaging. For example, a love interest for one of the avatars that might conflict with their duties in the brotherhood. Write in a way that makes the reader care about the characters and their journey.
One common theme is the exploration of loyalty. In the Dark Brotherhood context, Brynjolf might be involved in complex loyalty webs. He could be torn between his loyalty to the Dark Brotherhood's code and his personal relationships. Another theme is secrecy. The Dark Brotherhood operates in the shadows, and Brynjolf would have to keep many secrets. Fanfictions might delve into how he manages to keep his true identity and activities hidden from the outside world. Also, there's often the theme of moral ambiguity. The actions of the Dark Brotherhood are not always morally upright, and Brynjolf's character can be used to explore how one copes with such morally grey areas.
Paladin Danse is often a popular character. His loyalty to the Brotherhood and his complex backstory make him a great focal point in crossovers. Writers can explore his reactions to new characters or situations from other universes.
