A black haired girl about the age of ten was sitting there in a large open room, bookshelves were next to every wall with a fireplace in the centre. Her yellow slitted eyes gazed upon the book in her hands, the soft orange glow of the fire lighting up the book.

She heard the sound of knocking amidst the pitter patter of the rain on the roof, she slowly pushed herself off the lone worn armchair and walked toward a set of heavily worn stairs, she walked own them to the entry hall. Tall columns supported the roof, she walked along the crimson red carpet to a pair of red wooden doors.

She shouted loudly “Who is there!”

A voice replied “I am Amelia Bones, Head of the Magical Law Enforcement! We have detected extensive dark magic in this building, we polite request entry.”

The black haired girl scowled (I can’t kill them, their not Death Eaters! Fuck!) She clicked her fingers quickly, opening a black nebulous portal she then ran over to it. She clicked her fingers unlocking and opening the door as she leapt into the portal.

She found herself in a dark castle, the walls covered in worn banners and a carpet that was showing far less signs of wear and tear. She hears a menacing voice come from behind her “What are you doing here creature!”

She turns around to see a smaller unicorn with wings, the difference from most unicorns that she had seen was that the unicorn was almost as black as the darkest night wearing lighter blue armour with a starry mane. The girl’s hands glowed “I’m Astra Slytherin, you are?”

The unicorn boasted “I am Nightmare Moon, Queen of the Night and your future Ruler!”

Astra fired a blast of dark flames towards Nightmare Moon, Nightmare Moon dodged out of the way and fired a powerful beam of magic toward Astra. Astra conjured up a shield blocking the spell while conjuring up more dark flames to attack.

Nightmare Moon took to the skies, Astra began firing various different beams at Nightmare Moon. Astra sighed as Nightmare Moon dodged them all “You have one chance to back down before I do something that can’t stop!”

Nightmare Moon cackled “Don’t joke with me, you can't possibly harm me!”

Astra closed her eyes. She began morphing into a three metre tall, dark entity. Her body greyed changing to something that looked like a decaying corpse, a dark hooded cloak of ripped black cloth covered her. A rattling, breathing sound filled the air as the air suddenly became bitterly cold.

Nightmare Moon looked in utter horror at the monstrous abomination that Astra had become. A distorted voice came from Astra’s monstrous form “S̷t̵o̵p̵ ̸o̷r̶ ̴I̵ ̸w̷i̵l̵l̸ ̵d̵r̸a̸i̶n̵ ̸e̷v̴e̵r̷y̴ ̴h̵a̶p̵p̶y̷ ̴m̸e̴m̵o̶r̸y̴ ̵f̶r̴o̵m̵ ̵y̴o̵u̶r̴ ̵l̶i̸f̷e̷.”

Nightmare Moon tried to fly away only to be grabbed by Astra’s slimy looking, scabbed arms. Astra slowly dragged Nightmare Moon closer until they were both struck by a powerful Rainbow blast of light. Astra felt a burning sensation as her vision was filled with white before darkness claimed her.

Astra awoke in a large cell, she was chained to a concrete wall with chains that were cold to the touch and magnetically connected to the, similar bars separated her from the guards. Astra smirked (Impressive, Cold Iron. Immune to almost all forms of magic but not to Fiendfyre.) She formed Fiendfyre around her arms, the chains turned into dust from the dark flames. She then melted her way through bars, the guards panicked and ran out of the area.

Astra looked around the dungeon, it was dark and damp as befitting a dungeon. What irritated her was that there was very few rooms, this place was rarely used. She sidestepped a spell, only to see a similar unicorn to the first but taller and white. Unlike the other one, this one had a mane like an aurora.

Astra frowned “Friend of Nightmare Moon?’

The mare grimaced “Forgive my sister, she spent 1000 years trapped on the moon and was still angry at me. Her malice has been cleansed.”

Astra raised an eyebrow “What’s your name?”

The mare smiled “I’m Princess Celestia.” Celestia then focused on Astra “what was that thing you became?”

Astra frowned “I’m an Animagus, it allows one to transform into another form. In this case I can transform into a Dementor due to the dark magic experiments my father did to me when I was a baby. I think I am the only wizard or witch who can do this.”

Celestia focused on her “You seem very dangerous. Are you going to become a threat?”

Astra raised an eyebrow “Not to you unless you decide that you want me to be. I will defend myself is necessary and keep your sister away from me. After what happened I don’t wish to deal with her.”

Celestia frowned “The dark magic in your system is of great concern, it is so intrinsic to your being that Elements of Harmony couldn't separate it from you. Very few creatures can handle such dark magic body in them for very long.”

Astra shrugged “I have been alive for over nine-hundred years, I age very slowly. Biologically I am only ten. Every dark and light wizard has wanted to capture me since they discovered me so I have learned to fight.”

Celestia watched her warily, the pool off magic emanating off Astra dwarfed hers. Celestia frowned “How did you get such a large magic pool?”

Astra frowned “Dementors eat the souls of living things and add their magic to their own.” At Celestia’s scowl, Astra rolled her eyes “I only ate the souls of dark wizards who had murdered others for no good reason. I don’t eat the souls of just anyone. I created portal to this place in hopes of escaping the ‘good guys.’”

Celestia frowned “How did you get out of those bars, they were Cold Iron. Magic doesn’t work on them.”

Astra smirked “Fiendfyre, a dark magic flame spell that if one doesn’t have almost a lifetime of practice is completely uncontrollable but I have several lifetimes and perfect control. Nothing can resist Fiendfyre for long, even something that could stop the killing curse would falter under Fiendfyre.”

Celestia grimaced “Who would invent such a dangerous spell?’

Astra cracked her neck “Wizards who wanted to cause massive destruction to everyone around them, blood supremacists in particular who believe they were superior to those who were a mix of magical and non-magical people. Those who invented Fiendfyre wanted to wipe out the half-bloods.”

Celestia grimaced before shaking her head and smiled “How about we continue this conversation someone more pleasant then the dungeons.”

Astra smiled “I agree.” The duo exited the dungeons, the walls that seemed to made out of some crystalline structure were huge. Astra also saw banners of the sun on the walls, she saw ponies in gold plated armour carrying gold plated weapons.

A few of them as well as the other finely dressed ponies walked across the crystalline floor gave Astra odd looks. Astra ignored them as she walked alongside Celestia, who was one of the few ponies taller than her. They soon entered a large room made of the same materials as the hallways but with a large writing desk in it.

Astra frowned “If you are Princess then your sister is as well, why don’t you have moon banners on the walls as well.”

Celestia sighed “The nobles are not taking to kindly to her return. They want her gone.”

Astra growled “Nobles are just idiots, I would have them all tossed in the dungeon for malicious stupidity! The muggles tossed that system out years ago, they don’t have nobles anymore but democratically elected councils!”

Celestia smiled “Sounds like a much better system than the ones we have. Maybe we could implement something like that.”

Astra frowned “Where would I be allowed to stay?”

Celestia frowned “If you were to stay in the castle, that would raise some eyebrows. The fact you aren’t a pony would cause an uproar amongst the nobles.”

Astra frowned “Well I would wish to learn more about your magic while I am here. Could I at least stay in the city?”

Celestia smiled “Sure, I love to help others learn. It would if you could you tell me more about your species? You seem to be some form of ape or monkey.”

Astra frowned “While some believe that we have been created by a cosmic god, science has suggested that humans, my species evolved from apes and developed tools to survive against the predators of their world. Eventually turning the predators into prey. I have not paid too much heed to the argument as it changes little in the now.”

Celestia smiled “Well I know of two ponies who would love to take you in. I’ll even have you attend my school of magic. You will learn a lot there.”

Astra raised an eyebrow as she followed Celestia through the castle, into the busy streets of Canterlot’s Noble District. Fancy buildings were scattered all over the upper district, that reminded her of the fanciest of the pureblood manors.

Astra smiled “Biologically I am almost eleven, so if you ever see an owl with a letter attached to it please tell me.”

Celestia looked at her as they approached a much more humble manor house “I see, could we perhaps build an embassy in your world.”

Astra smiled “I own several properties back home, it wouldn’t be hard to do so. I should be able to open and anchor stable portals to each soon enough.” She then frowned “Just be warned, the wizarding community see themselves as superior to other magical creatures.”

Celestia raised an eyebrow as they approached the door “I’m surprised you don’t find our world strange?”

Astra giggled “Well I have seen so much, that little surprises me at this point. Now let’s meet those ponies you wished me to meet.”

Celestia knocked on the door, a grey mare with a white and purple mare opened the door. The mare bowed as she recognised Celestia “It’s honour for you to grace our home Princess.”

Celestia shook her head “There is no need for such formalities. I was hoping you were to house a foreign magician of incredible power, Twilight Velvet.”

Astra stepped forward “I’m Astra Slytherin, I have come another world far from here. Possible even from a dimension different from yours. I will staying you for a bit while I learn the magic of your world.”

Velvet smiled “Of course, our home has been rather empty without Twilight or Shining Armour here.”

Astra nodded to Celestia “I will be fine Princess.”

Celestia smiled “Then I must be going, I’ll be back tomorrow to take you to my school.”Astra nodded with a smile as Celestia left. She walked into the Velvet’s home, next to the mare.
