Obviously, Embry Call and Bella Swan are the main characters. Embry is a werewolf from the Quileute tribe, with his own set of abilities and a strong sense of loyalty to his pack. Bella, on the other hand, is a human girl who gets caught up in the supernatural world of vampires and werewolves in Forks.
One interesting plot could be an alternate universe where Embry and Bella meet in a different way, like at a music festival instead of in Forks. Another could be a story where Embry has to protect Bella from a new supernatural threat that is not part of the original Twilight series. And there could also be a plot where they team up to solve a mystery in the forest that involves an ancient werewolf or vampire legend.
Common themes include the power of the mate bond. It's often depicted as something very strong and almost magical, which can influence their emotions and actions. Another theme is the building of a new family or community. As they are mates, they start to create a new life together, and this involves making new friends or allies. There's also the theme of self - discovery as they learn more about themselves through their relationship with each other.
One common theme could be love triangles. Since there are three characters involved - Bella, Quil, and embry - the dynamic of a love triangle can add a lot of drama and tension to the story. Another theme might be self - discovery. The characters could be on a journey to figure out their true feelings for each other and themselves.
In this fanfiction, Bella Swan as Hecate could be depicted as a very wise and mysterious figure. She may use her knowledge and powers to protect those around her. Just like Hecate is often associated with crossroads, Bella might be in a position to make important decisions for the characters in the story. She could also have the power to transform things or people, which is a characteristic often linked to Hecate.
To develop Bella in this fanfiction, she could be given a mentor. Maybe an old witch who has been watching over her. With the mentor's help, she can learn about the history of doppelgangers in the witch world and how to control her powers. She can also struggle with the morality of using her powers, like whether she should use them to get revenge on those who have wronged her in the past.
Well, perhaps in the fanfiction, they go on a journey to find a way to ensure the baby's safety. Since Bella was previously involved with the vampire world through Edward, there could be some vampire - werewolf tension regarding the pregnancy. Also, they might have to deal with the reactions of their human friends and family, like how they'll explain this rather strange situation.
I've heard of a fanfiction called 'Embry and Bella: True Mates'. In this one, the author does a great job of building up the relationship. They start with Bella being a bit confused about the new bond with Embry as she had previous relationships in the original story. But as the story progresses, they learn more about each other and the significance of their mate bond. It's a really engaging read.
In fanfiction, the possibilities are endless. Regarding Bella Swan being an Original Vampire, it could be a fascinating deviation from the original narrative. An Original Vampire Bella Swan might have different abilities compared to her regular vampire self in other interpretations. She could possess unique powers that are characteristic of the Original Vampires in the lore. This could lead to different plotlines, such as her having a more significant role in vampire politics or different interactions with other characters, like the Volturi. Fanfiction writers often use such concepts to create unique and engaging stories.
