The dwarves who had the adventures with him might also enjoy listening. It would be a way to relive their shared experiences and remember the comradeship they had. They might sit around a fire and listen as Bilbo recounts their journey to the Lonely Mountain.
One idea could be that Female Bilbo Baggins joins a traveling caravan by accident. Maybe she was exploring the Shire and got separated from her group, and the caravan took her in. She could then use her wits and hobbit charm to make friends within the caravan, and they could have all sorts of adventures together, like facing off against bandits or discovering a hidden magical place.
A major theme in these fanfictions is the relationship changes. His friends, like the dwarves or Gandalf, might react differently to him as a vampire. Also, the theme of temptation is present. The urge to drink blood and how Bilbo resists or succumbs to it is often explored in detail. For example, in some stories, he has to find alternative ways to satisfy his vampiric thirst without harming the innocent. This adds a layer of complexity to his character and the story as a whole.
One possible theme could be a sense of betrayal. For example, if Bilbo feels betrayed by his companions during the adventure, it could lead to his anger. This could be related to issues like sharing of the treasure or decisions made during their journey.
He might also tell stories about the different creatures he met during his travels. Such as the elves in Rivendell. He could talk about their grace, wisdom, and the hospitality they showed to him and his companions.
Maybe the cat spirit animal has the ability to communicate with Bilbo in his dreams. It imparts wisdom about the journey ahead, like which paths to take and which treasures are truly worth seeking. The cat could be a connection to an ancient magic in Middle - earth that only Bilbo, as a hobbit with a special bond to this spirit animal, can access.
Common themes in 'female Bilbo Baggins fanfic' include empowerment. A female Bilbo can be shown as breaking barriers in a world full of challenges. Also, there is often the theme of adaptation. How does she adapt to the quest and the company of dwarves? It's not just about being female, but also about how that changes the story's flow. There might be fics where she has to prove herself more because of her gender, which is an interesting take on the classic story.
Self - discovery is also a theme. Just as Bilbo discovers his own courage and capabilities during his adventures, the OC may also be on a journey of self - discovery. They could be learning about their own powers, their place in the world, or their true identities, all while being influenced by their interactions with Bilbo.
One story could be that in a parallel Middle - earth, Bilbo was secretly female but disguised as male for the sake of adventure. She had to overcome the same challenges as the male Bilbo in the original story, like facing the dragon Smaug, but with the added layer of hiding her true gender from her companions.
