## Early Life

Kiallera Saoirse Prince-Slytherin was born on 25 December 2007 to Marvolo and Severus Prince-Slytherin, 17 years after the Second Wizard War.

She grew up as a member of the famous Prince-Slytherin family, a family well known for having a large amount of children, yet keeping their blood purity and the oldest of, as of then, three children. She loved her family very much, and constantly wondered what it was like to go to Hogwarts. On the day before her 11th birthday, Christmas Eve, she asked about Hogwarts to her mother, who stayed silent and said that her letter had just arrived.

Kiallera ran around their manor for hours with the letter, showing it off to nearly everything living or non living she saw. In the months coming up Kiallera excitedly wrote down everything she needed, including half of the stock at Weasley's Wizard Wheezes, her parents said no to a lot of it, but allowed her to buy some items she might need for defending herself, such as a large book nearly half of her weight called 'The Extended Guide To Curses, Hexes, Jinxes, and the Dark Arts.'

Kiallera became extremely excited for the arrival, knowing that she would continue her family legacy of being in Slytherin. Severus had also announced that he was pregnant again, making Kia very excited at having another baby in the family.

## Hogwarts Years

### Year One

Kiallera entered Hogwarts with a very energetic attitude, she quickly went for a nearly full compartment with 3 girls in it, the dark haired one seemed to be explaining all the subjects to the other two and Kiallera wasn't noticed until the sweet trolley came, with her pockets full of Galleons, Kiallera bought nearly half of the entire trolley filled with sweets. All 4 of them started up a conversation, while gobbling up all the sweets. Soon she knew everyone's names, and she had already picked a favorite friend out of them all, a fellow Pure-Blood named Alexis. She was pretty sad that she wasn't in the same house as any of the girls in the compartment.

During the Sorting Ceremony, Kiallera noticed her mother occasionally wincing in pain/discomfort. Upon remembering her new baby sibling was due any day now, she rushed up to the Head Table to offer assistance. Right before Severus could comfort his daughter, his waters broke and he went into labor in the Great Hall. Thanks to Madam Pomfrey, her new baby sister was born healthy, afterwards the school was mainly uneventful in Kiallera's eyes. Little did she know every month werewolf attacks were happening, her Mother had warned Kiallera that she might be next, and should be wary of the full moon at all times.

During Kiallera's Christmas break Katie gave all the houses except Slytherin large packages of plain muggle sweets. Kiallera didn't pay much attention to this and was rather humble of it, until she heard Alexis Ravenwood talking to Katie outside the potions classroom, Kiallera was the 1st to know of "The Duel" and quickly spread the gossip to all the other Slytherins, along with a couple other students.

#### The Duel

The Duelling Club Session took place in the dungeons, and after a student had exploded their cauldron filled with Blood Replenishing Potion, the dungeons incredibly stank, causing a distraction for all attendees. The stakes were also incredibly high on this duel, if Katie won, Alexis would have to buy her all of next years school supplies, Is it was the other way around, Katie would have to apologize and buy all of Slytherin some sweets as well.

Kiallera was hooked on every moment of the duel, excitedly cheering for her friend till it was over. Alexis had won, and with a jinx Kiallera had taught her, all of Slytherin was celebrating in the common room over the duel, even though Alexis wasn't a member of her house.

#### After The Duel

Afterwards Kiallera told Alexis she felt uncomfortable around Katie, which Alexis gave much advice for, including to jinx her. Kiallera on the otherhand, felt as though this was not the way, and only threatened to Jinx Katie. But it paid off anyways, Kiallera was given 2 boxes of sweets, one she gave to Alexis for giving her advice and the other one she kept to herself.

#### Spring Ball

Kiallera was picked as the last Nominee for 1st Year Potions, something she was rather excited about. She was finally able to pick out her dress at Madam Malkins, a green representing her chosen Flower (Hellebore) and her house, although she wasn't able to find a partner, she was fairly happy with the time she had there, which included spending time with Alexis and Lavender. Kiallera was also invited to the Slug Club after the ball had ended.

#### Years End

In the end of the year Ravenclaw won the house cup, Kiallera was pretty happy with Slytherin's 3rd place and had at least beaten her Arch Rival's house in points.

### Year Two

In her second year, Kiallera entered Hogwarts a little more subdued than the previous year. She was at least glad to be at Hogwarts again, But soon enough she was enabled with the stress of classes, especially the stress of her DADA classes, her professor was nice and not too focused on her grades. She was often at the library with Alexis or Lavender studying as many DADA books as possible. Eventually her mother summoned her to his office, and asked if Kiallera was interested in DADA lessons with his former student, Harry Potter. Kiallera happily agreed and began taking classes every weekend, until Harry revealed that he was tutoring another student, and the two would face off in a duel on next Wednesday.

#### DADA Duel

Soon the dreaded next Wednesday came, Kiallera walked in wearing an unusually long black robe much like her mother's. To her surprise the other student was her friend Alexis who started off the duel with Bombardo and Kiallera quickly was distracted with it. Kiallera was next and had cast Flipendo, eventually the duel had come down to a battle of the most dangerous hexes and jinxes imaginable. Alexis decided to make her final move, she'd been trying to create a spell for a few weeks, and was pretty sure she had it down, and with a quick flash of her wand, had cast the final and winning spell of the duel. Harry was very impressed, first by Alexis's capable magic ability to create and properly use a spell, and second for her creativity. She was found about to walk off the astronomy tower by Aurora Sinistra later that night, and was also sent to the hospital wing after complaining of her shoulders being sore. Where Alexis visited her and taught her how to use the hex.

#### Potions Training

Once again her mother had called Kiallera to his office, but this time for a different Reason, Kiallera was asked to partake in an advanced potions class with Harry, Kiallera gladly accepted and in a few weeks, Kia and Alexis were ready for their test.

#### Potions Test

Alexis and Kiallera were summoned on a gloomy spring morning for their potions test, which consisted of 20 different tasks. Each were given a list of things to do, the amount of time given was till sunset, and they could travel wherever they'd like to obtain the items, Harry had given them a clue to the location of the first ingredient. As soon as the two had left the classroom, Kiallera admitted to Alexis that she was a bit scared of brewing a potion on the 4th and 5th year curriculum, and asked if they should search together. Alexis comforted her friend by teaming up, and hugging her afterwards.

For about 10 minutes they brainstormed where to search for the ingredient based off of the clue, and eventually decided to explore and adventure the Forbidden Forest, little did they know, a sneaky Delphini Riddle. Followed them along the path, as soon as they were well deep into the forest, Delphini had cast the Full-Moon Charm, awakening the pack of werewolves within the forest, including the dangerous Kada Greyback. In the nick of time, Alexis had seen, and had grabbed the first ingredient to their potion, the Pink Waxcap Mushroom. Kiallera had already started to run, but was sure not to get out of Alexis's range of hearing or sight. Eventually the 2 making it out of the forest and finding their 2nd clue, on the grounds though, they had discovered a Transformed Werewolf (Most likely Xavier Lisong or another student), Which Kiallera and Alexis tried running, but Kiallera tripped over a rock and was nearly bitten if not thanks to Alexis using Bombardo to distract the creature. Alexis and Kiallera quickly got inside of a room inside the castle, and read their next clue, which was easily deciphered by Kiallera. The 2 rushed to the Clocktower courtyard afterwards, where students spectactled over the random unexplained full moon in the sky. The 2 scaled the tower with an Ascendio (Used by Kiallera) and the staircase (Used by Alexis) to grab their 2nd ingredient.

About an hour later, the two were caught breaking into the Caretaker's office looking for another ingredient, they were both slapped with a whip 4 times for breaking in and Kiallera blamed Alexis for getting the clue wrong.

#### Test-Grades and End of Training

In early May, Harry had given back Kiallera's potions test grades, she was expected to ace the subject and had passed with even more than an Ace, she destroyed the limits on the entire assignment, which Harry confessed he had stuck hearing buds, under their robes and had heard everything that happened. Kiallera was proud of her achievements, and her mother had bought her some new books for next year due to her excellency.

### Third year

Kia started the third year with a renewed pep-in-her-step, she was proud to be one of the very few students taking excelled potions (along with Alexis) in a 5th year class, but with that implied more pressure, as she was taking 2 potions classes and had to drop her Herbology Studies elective due to this. At this point she began to develop more than friends feelings for Alexis, and didn't know exactly how to control them, with Alexis inviting her for a 'hangout' at Hogsmeade. Although she didn't realize it, Katie surely did and tried her best to stop it, telling nasty rumors about Kiallera to Alexis and attempting to jinx Kiallera.

Kiallera, being the smart girl that she is, quickly caught on to Katie's scheme and diffused the rumors before they could get out of hand. After a couple more 'hangouts', Alexis finally confessed that she was in love with Kiallera. Kia quickly started tearing up happily and returned her feelings before leaving Alexis with a kiss on the cheek, something that left the latter a blushing but happy mess.

### Fourth Year

Kia began her fourth year with confidence in her step. However, she came across a prophecy involving her, her friends, and Delphi Riddle.

## Later life

### Marriage and Vampirism

A few months after she graduated, Kia married her best friend Alexis Ravenwood, but only a year of joy lasted for the couple as while Alexis was pregnant with their first baby, she was diagnosed with Shade Anemia, a rare but natural deadly genetic infection that is only found in wizards, the only cure being death or a transformation into a vampire. At the news of death, Kiallera promptly collapsed and after only two days of falling ill, was too weak to even leave her bed. Alexis told her that she would find the best vampiric coven to help treat the ailment. She eventually found a poster for the "Olympia Medical Coven" and dashed home to show her the discovery, which she weakly nodded for. Alexis quickly took the floo powder to the Cullen Household, only to discover nobody was home. She left a note for the vampires to floo or apparate to the Prince-Slytherin cottage and they'd be waiting for the transformation.

At approximately 10:19 PM on a Saturday night did a member of the Cullen Family apparate to their household, even Alexis was memserized by her beauty as she was even more pretty than Kia. The woman stated her business and her name: Azalea Cullen. The couple had heard of how a young woman married into the Cullen family and had hybrid triplets.

Alexis waited by her bedside and told her everything would be okay and that just like Lavender, she would adapt to being a non-human in no time. Alexis had no word as Kia and Azalea had a discussion on what type of transformation she would like. The final decision was a venom Injection through the heart 5 times and multiple bites on the body.

Alexis not wanting to interrupt the transformation session, slid out of the room and stayed away from her and Azalea for 3 days until she appeared in Alexis's doorway. Kia was beaming and more beautiful than ever before, her eyes a bright reddish but slightly diluting golden color. Azalea left a note on all things needed for her not to attack Alexis and left the household.

## Physical appearance

Kiallera was a very beautiful young woman of ivory skin and a slim build with dark red hair that fell below her waist and the Prince-Slytherin family's famous emerald green eyes. Many of her professors, including Harry, have actually mistaken her for Lily Potter.

Due to her prettiness, Kiallera was perfectly capable of attracting a certain amount of attention from boys. In her moments of rage, however, her eyes seem to glow an eerie shade of green that scared most people; including her best friend.

She usually has a kind and gentle smile on her face, which is unusual for a Slytherin, and her beauty is one reason for her popularity rising. At the age of 20, after falling ill with an incurable wizard illness, Kia was transformed into a vampire to save her life. After her transformation, some thought she was too beautiful to look at as her eyes had turned from her emerald green to a striking gold after months of drinking animal blood.

## Personality and traits

Like her mother stated, Kiallera is a mirror copy of Lily Potter in both looks and personality. She was known for being a responsible, vivacious, talented, and popular student. She was also kind, gentle, smart, protective, loyal, and willing to sacrifice her own wants and needs for the benefit of her friends. An example of this being that she was willing to break up with Alexis in order for her and Katie to stay friends.

Due to her mother's busy schedule as a Potions master and DADA professor, she had taken it upon herself to make sure that his quarters were clean, Aleza asleep in her crib, and a hot, home-cooked meal waiting for him. Outside of her classes, Kia was a social butterfly with many friends. Most of the people who knew her described her as energetic, kind, fun, and understanding. As stated by Alexis, Kiallera had this aura that radiated warmth and comfort.

Even after becoming a vampire, Kiallera adapted pretty quickly to her new life.

## Magical abilities and skills

True to her title as a prodigy, Kiallera excelled in a majority of magical fields of study. There were also a few domestic skills that she perfected the Muggle way instead of using magic.

## Possessions

* **Standard Hogwarts Supplies**: Kiallera kept all of her Hogwarts Supplies in her trunk, even in her final year of magical education.
* **Wand**: Kia owned a wand of snakewood, phoenix feather with 11's length.
* **Dress Robes**: Kiallera owned many dress robes for formal, semi-formal, and casual wear. When she was asked to the Spring Ball, she donned floor-length green dress robes with yellow marigolds sewn onto the collar.

* **Promise Necklace**: This necklace is one of Kia's most treasured possessions because it was given to her by Alexis on her 16 birthday. Alexis explained that it was her version of a promise ring, cementing her commitment to their relationship. It also made Kia realize that Alexis hoped to marry her one day.

## Relationships

### Love interests

Alexis Ravenwood is Kiallera's best friend and love interest. She was one of the people who defended her from Katie Wolf's wrath and comforted her afterward. The couple, even before they started dating, hardly had any disagreements and would do anything to protect each other.

Both of them compliment and complete each other as well, with Kia allowing Alexis to loosen up and relax while Alexis keeps Kiallera grounded and focused. Alexis even gave her a promise necklace on her 16th birthday.

In return for defending her from Katie, Kia taught Alexis some of her mother's jinxes. About a year after they started dating, they moved into a cottage together. They care about each other deeply and while the two are protective of each other, both of them know that the other can take care of herself. They eventually married at the age of 19 and after a year of marriage, had a daughter.

Their loyalty to each other also extended to the fact that Lexi refused to abandon Kiallera after her transformation into a vampire.

### Family

#### Severus Prince-Slytherin

Severus Prince-Slytherin is Kiallera's mother. They have a very close and affectionate relationship and were protective of each other and their family. A secret known only to their family and Alexis was that Severus Prince-Slytherin was actually Severus Snape, who everyone thought had died during the Battle of Hogwarts.

### Rivals and Enemies

Katie originally appeared fairly friendly to Kiallera when she first met her, but after the sorting became more toxic, especially toward Kiallera's Hogwarts House. In truth Kiallera hated jinxing Katie for the beginning of her education, but as Katie's hatred to Kia increased she didn't feel as much guilt doing so.

### Professors and Mentors

#### Harry Potter

Harry Potter was Kiallera's shared DADA tutor during her second year. In the time they spent together, the two developed a father-daughter bond, with Harry revealing that he promised her mother that he'd protect her.

## Lavender Bronee/Ravenwood

When Lavender and Kia first met, there was obviously some type of unnatural bond much like with Kia and Alexis later on, after Katie's hate of the group (Plus Kia and Alexis dating) Lavender become somewhat like a therapist to Kia, with Alexis sometimes helping. Although Kia was uninformed of Lavender officially being a member of the Ravenwood Family until 6th year, she still adored Lavender as a friend.
