Moonlight Serenade (OFC Swan x Aro)

Forks was Bella's idea.

A quiet town. Time with Charlie.

Bella's little sister arrives with ballet slippers in her bag, vintage skirts in her suitcase, and a presence that doesn't quite fit anywhere- and yet somehow fits everywhere. Ariana is warm where Bella is guarded, observant where others are oblivious, and far more perceptive than anyone realizes.

This AU stays close to the bones of Twilight. The same town. The same people. The same unfolding events.

But small differences have consequences.

Because Ariana was never supposed to exist.

Her presence creates subtle fractures in a story that once felt certain. Conversations change. Reactions shift. Threads that were straight begin to bend. And while Bella's life follows a familiar path, another story quietly grows in the background- one that won't truly surface until New Moon.

Far away in Volterra, an ancient vampire king lives exactly as he always has: brilliant, theatrical, manipulative, and utterly unhinged.

Aro just hasn't met the one variable the universe accidentally introduced yet.

This is a transmigrated/ Isekai FF where the OFC does not recall her past life but those memories are imprinted as intuition on her part. Her passions in her past life that she never got to explore as much as she wished are why she is the way she is now. She was 28 when she died and had been a Rattie in her teen years. But none of that matters in her life as Ariana Swan.
