The shackles of immortality (Volturi)

In the legends of Volterra, it is whispered about a maiden, beautiful as the moon itself, imprisoned in the stone walls of the castle. Some say that she is a ghost of the past, others that she is a prisoner who cannot cross the threshold. Some call it a symbol, others a jewel, but no one knows its true history.
but she remembers everything.
Cornelia once lived in another world where the Volturi were just lines from a book and stills from a movie. But one day reality was distorted - and she woke up in their castle.
Her days merged into an endless stream: gold, silk, smiles that could not be refused, and fear from which there was nowhere to escape. She was given everything except one thing-freedom. She wasn't a prisoner, but she wasn't in control of her fate either. Her name was pronounced with reverence and envy. It was said that her smile could warm even a stone heart, but she herself had long forgotten what it meant to smile.
In truth, her life doesn't belong to her.
The story that begins here is not about freedom or power. It's about how a fragile soul trapped among the immortals will one day encounter things that those who live in the shadows shouldn't know about.
