Another plot idea is that there is a competition among the black twilight wolves for leadership.

One idea could be that Bella discovers she has a special power that only she can use to protect the wolf pack. For example, she might be able to communicate with the spirits of the forest which give her warnings about upcoming threats.
Well, in some fanfiction, the plot might involve the wolf being a part of a prophecy related to Hermione. For example, it could be foretold that only she can save the wolf from an impending doom, like a dark magic that is slowly consuming it. This would lead her on a journey to find a cure or counter - spell. Also, the wolf could be a link to Hermione's past that she was unaware of. Maybe it was somehow connected to her family's hidden magical heritage, and as she gets to know the wolf, she uncovers long - lost family secrets.
One plot idea could be Bella struggling to choose between her vampire life with Edward and her deep friendship with Jacob that has the potential to turn into more.

Well, you could have a fanfiction where the magic in Fabletown starts to malfunction. Bigby has to figure out why while also dealing with the chaos it causes. For example, fables' true forms start to randomly appear. Another idea is a love story set within the 'A Wolf Among Us' universe. Maybe a fable falls in love with Bigby, but there are obstacles like the fact that he's a wolf and has a dangerous job. Or a plot where some of the non - fable humans in Fabletown start to suspect that there's something strange going on and Bigby has to keep them from finding out the truth without using too much force.
A plot could revolve around Bigby Wolf's baby growing up in a world that is not very accepting of his dual nature. The baby has to face discrimination from some of the other Fables. However, with the love and support of his family, especially Bigby, he learns to embrace who he is and even uses his unique abilities to change the minds of those who once shunned him. It could be a story of self - discovery and acceptance.
