I'm not sure who Ariel is in this context without more information. It could be a unique character created specifically for this 'never - ending story' that has its own set of characteristics and a role within the plot.
Ariel could be any character created by the fanfic author. It might be a mermaid, as the name Ariel is often associated with mermaids in popular culture.
The allure lies in the clash of their personalities. Bella is often depicted as strong - willed and kind - hearted, while Klaus is complex and brooding. Their interactions can be electric. In fanfiction, we might see Bella challenging Klaus' more villainous tendencies, which is really interesting.
It's likely a fan - created story related to the Salvatore characters. Fanfiction often takes existing characters from a show or book and creates new stories around them. In this case, it might explore different aspects or scenarios of the Salvatores' lives, relationships, or adventures.
I'm not sure specifically as there could be many different interpretations. It might be a fanfiction centered around a character named Mal who has some sort of relationship or story within the Salvatore universe. Maybe it's about Mal's adventures with the Salvatore brothers or her role in the events of that particular fictional world.
To summarize a short story by Salvatore, you'd need to look at the central idea, the characters' development, and the climax. Without knowing the exact story, it's difficult to provide a detailed summary.
Ariel is mostly not a real story. It could be from a fantasy world, a product of someone's creativity. There's no historical or factual basis for it to be considered real.
She could be more assertive in a rather dark way. Ursula is a very dominant character. Ariel, growing up under her influence, might not be as gentle as in the original story. For example, when it comes to getting what she wants, she might use more forceful or underhanded methods, rather than her pure - hearted charm in the original.
