Well, in a Brianna and Fiora story romance novel, perhaps Brianna is a shy girl and Fiora is a more outgoing one. They could be from different social backgrounds. Maybe Fiora helps Brianna break out of her shell, and as they spend more time together, feelings start to develop. They might go on adventures, discover new things about each other, and their love story unfolds against a backdrop of beautiful settings and interesting events.
The theme of self - discovery is also quite common. Through their relationship, both Fiora and Riven may learn more about themselves. In some fanfics, Fiora discovers a new side of herself as she gets to know Riven better. And Riven may come to terms with her past and her identity through her bond with Fiora.
The plot might involve Aatrox being intrigued by Fiora's unwavering courage. He could see in her a potential to be a great warrior on his side, not as a minion but as an equal. So he tries to persuade her to join his cause, which leads to a series of intense dialogues and battles between them, as Fiora is hesitant but also curious about Aatrox's power.
One popular Fiora x Riven fanfic is 'The Duelist's Bond'. It explores their relationship in a world filled with challenges. They start as rivals but gradually develop a mutual respect that could potentially turn into something more. The story is full of great fight scenes and emotional moments.
For Fiora, you can focus on her noble upbringing and her sense of honor. Show how these traits influence her actions when she meets Aatrox. For example, she might be disgusted by Aatrox's use of dark magic but also respect his power.
For Aatrox, you could focus on his past as a Darkin. His internal struggle between his dark nature and any glimmers of his former self could be explored. Show how Fiora's presence either exacerbates or soothes this conflict. For Fiora, her pride as a duelist is key. You can show how she reacts when faced with Aatrox's power that might be greater than what she's used to. Does she become more determined or is she momentarily daunted?
No, Digimon. The dark and light series of Digimon were not mutually exclusive. In fact, dark-type Digimons were usually suppressed or destroyed by other types of Digimons. There were many types of Digimons in the world of Digimons. Each Digimon had its own unique attributes and abilities, and these attributes and abilities would vary from individual to individual. Therefore, the dark-type Digimon was not a Digimon that could suppress all types except the light-type.
One common theme is friendship. The OC often forms a strong bond with Aura Bella Fiora, like in many stories where they rely on each other through thick and thin. Another theme is adventure. They usually embark on exciting journeys together, exploring new places and facing unknown dangers.
A theme that often appears is the power struggle. Given that they both seem to be strong characters in their own right, fanfics might explore how they deal with power dynamics between them. Maybe they compete at first and then realize they can be stronger together. It's also possible to see themes related to loyalty and betrayal. For instance, they might have to choose between their loyalty to their factions and their feelings for each other in some fanfics.
