Chapter 1:

In Tuscany, Italy, there is a town called Volterra, and in this ancient Italian city, it is rumored and proven true by some, a coven of vampires named the Volturi resides. These vampires are one of the most ancient, largest, most powerful, and highly dangerous vampires that one could meet, be it a fellow vampire or human; but even though the Volturi are extremely deadly, the town Volterra is one of the most safest place that one could live in. This baffling and most incredulous reason is because the Volturi had made a law, known to all vampires, that hunting in Volterra is strictly illegal and not permitted in order to keep the secrecy of vampires and so that they wouldn't deal with exposure.

The Volturi are of the equivalent of royalty in the vampire world, and they are the ones that enforce the laws. They are the guardians, keeping the secret society of vampires hidden from the human world. They sometimes send their agents around to travel from Volterra to prevent some covens from exposing vampires. They have existed for over three thousand years, and during these years they have done much good, but alas, Aro Volturi, their leader and king was starting to lose his way.

Aro Volturi was the eldest from his two other siblings and was bitten by a random vampire at the age of twenty-five; not wanting to live his immortal existence alone, he bit his younger brother Caius, who was twenty-two at the time and his sister Didyme, who had just turned eighteen. A decade later, Aro stumbled upon a lone vampire, who wandering around Greece. He introduced himself as Marcus and once Aro discovered that he was merely nineteen years of age and all by his lonesome, Aro took it upon himself to invite Marcus to meet his siblings. The second Marcus and Didyme shared eye contact, they knew they were mates.

During their first decade as vampires, Aro discovered that he had the power of telepathy, and that with the mere contact of his skin with others, he could read every single thought and event that occurred in the person's life. Aro and Caius later discovered that their sister Didyme, had the gift to induce happiness, which came as no surprise seeing as during their mortal life, they couldn't be around their little sister without wearing a smile on their faces, be it reluctant or not. However, when they met Marcus and discovered that he had the gift to identify relationships, allowing him to see the emotional ties between individuals; Aro came up with the idea of starting the Volturi coven and become the enforcers of the law in the vampire world.

The vampires all around the world came to respect the Volturi for keeping them safe, ensuring that they never became extinct, and made sure to follow their laws and due to that, the vampires thrived in their immortal lives with no fear of being discovered by the humans. Aro met his mate Sulpicia later on and Caius met his mate Athenodora. The three leaders became happy in their immortal existence and with their mates by their sides; they never feared a lonely and depressing immortality. But not all good things have a happy ending, for Aro became obsessed with power, especially after one of his closest and most dearest friend Carlisle Cullen left him to begin a vegetarian diet, leaving Volterra and starting his own coven, which began increasing in numbers along with the Denali Clan. Caius became bitter and always wore a frown on his startlingly perfect face. Although Caius and Athenodora loved each other deeply, they became bored with one another and Caius would always catch his wife tumbling in the sheets with some random vampire from their guards. In fact, only Marcus and Didyme were extremely happy, and it was an often habit of theirs to travel around to exotic places for a few weeks and back to Volterra to their family and coven.

It was during the year 1958, when things changed completely for the second king and leader of the Volturi, Caius, and this is where the story begins.

***Affari Nascosti***

Maia McKinnon was sitting in the McKinnon manor with her twin brother Michael having breakfast. It had been two days since they graduated from Hogwarts school of Witchcraft and Wizardry and the twins were impatiently waiting for a letter from the Ministry of Magic for the NEWTs grades. Michael was hoping for Outstandings and Exceed Expectations in order to apply for his job as an auror and Maia was hoping for all Outstandings as it was her dream of becoming a healer as she enjoyed helping people.

The McKinnons were a highly respected pureblood family and extremely wealthy, so the twin siblings didn't need to look out for a job as they could have lived their whole happy lives with no work pay and never run out of money, supporting their great-great grandchildren; but Michael and Maia got bored easily, they loved to help and protect others, and since they were both sorted into Gryffindor, the house of the bold, brave, daring and chivalrous, it was in their blood for them to go and do something with their lives and help others.

Once Jonathan and Evangeline McKinnon joined their children for breakfast which was laid out by their trusty house elves, Michael cleared his throat and announced that he was going to ask for Estelle Proudfoot's hand in marriage. Maia saw it coming; her brother and Estelle, who was sorted into Ravenclaw, had been dating for four years and were completely in love with one another. Jonathan McKinnon barked out his congratulations while he went to retrieve an engagement ring that has been passed down through the family for generations, so that Michael could propose and pass it down to his children and so on, and Evangeline McKinnon started crying tears of happiness, rambling about decorations and plans for the wedding mentally as well as sending an owl to Lady Erica Proudfoot (Estelle's mother).

After they finished celebrating, two barn owls arrived with Michael and Maia's NEWT scores and after achieving all O's and EE's, going through another round of celebration, Jonathon, Michael and Maia apparated out of the manor to go to work and in the twin's case to set out their job applications, while Evangeline apparated to Diagon Alley for wedding preparation.

***Affari Nascosti***

It has been two years since Michael and Estelle's grand wedding and one year since the birth of Maia's nephew Alexander McKinnon and life has never been better. Maia moved out of the McKinnon manor to live by herself in a small dainty apartment in the outskirts of Diagon Alley and she was thriving in St. Mungo's as an intern healer.

However, Maia was unhappy. Yes, she had a beautiful and healthy nephew who was also her godson. Yes, she had the most loving parents and an amazing brother. Yes, she was an extremely skilled and natural healer and she couldn't wait to be promoted. And yes, she had great and wondrous friends. But Maia McKinnon was very lonely and starved for love and affection; the kind of love and affection that couldn't be given by her friends and family. She wanted a husband of her own and after delivering many new wizards and witches into the world; her heart ached for a baby of her own, preferably a girl.

Which is why, when Maia McKinnon went to the weekly family gathering of the McKinnon and Proudfoot family at McKinnon manor, Maia announced at the end of dinner that she was taking a leave of absence from work for a couple of months and moving to Italy for a little vacation. Her parents and brother were sad to see her go, but they understood that Maia needed to find her own way and hopefully meet a wizard, since she hadn't met one that she liked in London.

Maia thanked Merlin that her parents weren't those uppity blood purist purebloods that believed in arranged marriages as she packed her suitcases with the essentials and pocketed her credit card from Gringotts as she wasn't comfortable carrying a sack of galleons, sickles and knuts with her. Maia already had a portkey registered to the Italian Ministry of Magic and after one last glance at her cozy apartment; she laid a finger on the crushed can and uttered the password.

After ten excruciatingly uncomfortable minutes of dizziness and colors blurring into each other, Maia graciously landed on the outskirts of the ministry of magic and gave up her portkey to one of the attendants collecting them. After she registered her name and where her apartment was located in, she apparated into an alley in Tuscany, Volterra, making sure her shrunken trunk was in her pocket, Maia strolled down the beautiful city of Volterra and made her way to her apartment building which was situated right in front of the clock tower.
