"Fire, Fire all around. Gonna burn it all down. Fire, Fire all around. Why can't you simmer down?", the class cheered in unison.

It had been the 17th time this week that she had had a magical outburst. Ever since her parents left her and she lost her home, everypony in town hated her. It wasn't fair. She hadn't done any wrong. She couldn't control it. The doctors say that it might be a disease. Others say she just needs to be locked up. It was sad to see the little black furred and blue-black maned pony cry, the ends of her mane still smoking slightly. She had spontaneously burst into flame this time. The teacher couldn't pick her up due to the fact that she was still too hot. The class either cringed in fear of laughed at her, joining in the cheer. So she cried, her magic only was 1/6th depleted. For most unicorns, an outburst like hers would've completely depleted their magical supply.

Eventually though, the teacher picked up her small form and carried her out. The teacher promptly threw her into the mud on the outskirts if town, again. Everypony hated her. The teacher wanted her out because she never wanted her in the class to begin with. The teacher was strict but she feared the filly, like everyone else. Everyone feared her power. The filly sobbed in the mud. She heard the sounds of carts and hooves pass her, none stopping. She was hated, an outcast. No home, no food, no family, no friends. Nopony. She eventually stopped crying but stayed where she lay. Why should she get up? There was nowhere to go anyway... She heard beating of wings and a cart touch the ground. She ignored it and continue to lie still. She heard soft hoofsteps near her.

"You might as well leave; nopony will like you if you take pity on me.", She said to the mud, not even turning to see the pony.

She had had travelers pick her up time to time. One outburst later, she was back where they found her. Travelers quickly learned to stay away. Not this pony.

"Why should I? I mean, I am supposed to take you home.", called a regal yet concerned voice.

"Why are you wanting ME to come?", asked the filly.

"I heard you need a home. My sister doesn't know, but I insist you come", said the pony.

She stood now, "I am a unicorn who has a magical instability problem and I could blow up in your face! You don't want me near you!", she shouted.

"Hmm, it seems you should come then. I believe I have a teacher who can help you.", the pony said and stepping closer.

She was angry now. She tossed her mane and ran away into the Everfree.

"No! Wait!", called the pony.

She didn't stop. The filly untucked a small blade concealed in the cloak she wore. The unicorn teleported away. She stepped into the cave she called her home. She held the blade in her mouth. the drew it across her flank, blood catching on the knife and flung it at the ground. Magic built a barrier at the front and the darkness of the room intensified.

Black magic, she thought,Banned and yet i'm the only one who can control it. Sort of at least.

A flash in the corner assaulted the unicorn's eyes.

"Ack!", she screamed,"That wall was supposed to prevent ponies getting in!"

"Not if that pony is a princess", said a familiar voice.

The filly turned to see Princess Luna and gasped, crying out,"Oh please don't lock me away! I don't mean to hurt anypony! It just happens!!!"

The Goddess of the Night smiled,"Why would I ever do that?"

The filly stumbled over her words and Luna interjected,"I see that you delve into forbidden magic. I do not blame you. The magic is powerful but, it isn't always bad. I shall teach you how to use your magic, if you may come."

"You want me to come with you? But you don-",She began.

"You will not be tortured like here, you have a home and friends and food.", she cut off,"You will learn greatly, like that of Princess Twilight and Celestia. My personal student."

The filly gaped at the princess, unsure of what to say. Luna smiled and took her under her wing. The filly calmed and slowly nodded. The magic was released from the entrance of the cafe and the two walked back to town. Upon reentering the town, ponies had gathered. They were angry and fearful. the mayor stepped forward.

"You highness, I apologize for any problems SHE has caused",the mayor said pointedly,"I assure you that we will fully welcome you into our town after we send this filly to her home."

"She stays with me",said Luna forcefully.

"She will harm you princess, she isn't like what you see", cautioned the mayor.

"And the ponies here aren't either. You disappoint me. This filly calls upon magics to protect her and you beat her down for it. She doesn't live in the town and must scavenge for food. You drive away those who want to help her. She shall be my new student and will come with me to Canterlot",Luna said, all regality gone and she was keeping the filly close to her,"Now if you will excuse me..."

The two stepped on the night chariot, the sun's red-orange glow casting a shadow. The filly said nothing, not even goodbye to the angry mob.

At least she's humble, Luna thought.

"My name is Night Caster by the way",the filly said.

"I know", said the princess.

The ride was short, the trained bat ponies flying true. Night Caster stood next to the princess in obedient silence. What could she say? This was the Princess of the Night standing beside her, rescuing her from the nightmare that was her home. Nothing was said between the two. Luna thought that the filly was scarred as she shivered in the cold wind and wrapped a consoling and warm wing around her, pulling her close to her warm body. Night Caster tensed at first but relaxed and leaned into the princess trustingly. This is good, Luna thought,She trusts, maybe she'll be a good student after all...

The carriage landed softly with great practice and the two stepped off, Luna's wing still around the filly. Luna led her up the stairs of the castle in the fading sunlight, and in to the throne room.

"And who is this?", called a soft warm voice inside.

The voice belonged to Princess Celestia, sitting together with the new Princess Twilight and Princess Cadence along with Shining Armor. In front of them lie a table with a map of Equestria and tiny black pinpoints that contained Luna's cutie mark. Night Caster noticed it and wondered if Luna told anyone of her absence.

"You know dear sister, leaving without telling anypony isn't very becoming of a princess...",said Princess Celestia. Well that confirmed the theory.

"Yes, but I bring you a pony that is of importance.",Luna replied, removing her wing to reveal Night Caster.

The black pony stood, her fear returning.

"Why is she important?",asked Twilight.

"She shall be my new student.",replied Luna with casualty.

"WHAT?!",all 3 others shouted. Not accounting Celestia.

The next hour was spent calming the four down, especially Night Caster, she almost blew up in Luna's face, as she said she might.

"Student. I expected this as you saw Twilight being such a good pony, but this one?",asked a irritatingly calm Celestia.

"Yes, this one suits me well.",replied Luna.

"If, I may interject, how so, Auntie Luna?",asked Cadence.

"She uses the Magic of Night. Naturally.",replied a ever calm Luna.

Even Celestia was surprised. Night Caster shrunk slightly.

"SHE USES BLACK MAGIC?!",shouted Shining Armour.

"Yes, but not in the same way. Black magic is powerful, but not always evil. What do you think I use? Do you expect the Magic of Days from the Night Princess?",contorted Luna.

"Black Magic was banned, but I assume she didn't know that?",asked Celestia.

"When I met her she was splayed in the mud, forgotten.",said Luna, avoiding the question.

Night Caster stepped out from behind Luna, her slight form scarcely noticed.

"Black magic IS evil. No matter the caster.",said Twilight but something was off with her voice.

Celestia caught the tone and turned, everypony doing the same. A dark glow radiated from her eyes and the lights were shut out, night falling upon them.

Twilight laughed, her voice dark and unforgiving as blue/purple flames erupted around her, revealing none other that King Sombra.

Night Caster screamed.

"Now little filly, no need to be scared, this is your future, power and darkness, combined!",laughed Sombra.

"NO!",shouted Night Caster.

Sombra smiled,"I didn't come back from death by a simple spell, it was the constant lull of your power. Black magic is naturally evil. Luna fell, so will you."

"Luna ROSE though, she's right here!",shouted Night Caster.

Sombra changed the subject.

"Well Luna, Celestia, Cadence, your little Twilight is in trouble",said Sombra as he raised a hoof,"Give me the filly or the little Princess is dead. Try and fight, she's a goner"

"Guards, attack!",shouted Celestia.

The guards attacked and Sombra slammed the hoof down. A scream was heard above them. Shining charged Celestia. Sombra faded into black mist with a evil laugh echoing. Shining pinned Celestia easily and was punching her face.

"Shining stop, she's not dead!",Cadence screamed.

Night Caster ran to where she heard the Princess of Friendship. She charged into a door to see a crumpled but alive Twilight. Twilight moaned but Night Caster approached.

"I'm Luna's new student, Night Caster ma'am. I'm here to heal you. I use black magic, but i promise it's safe. Do you trust me?",asked Night Caster, working fast to help Twilight into a position of receiving power in black magic terms.

Twilight nodded weakly. Knowing Luna well enough to pick the pony as her apprentice.

Night Caster charger her horn, light fled the room and a blue/black aura surrounded Twilight. Relief spread over her body as the magic healed bones and closed wounds, she felt strength return as the filly worked the magic into strengthening the bones. The light returned and the filly looked at Twilight.

At the moment, Shining burst in to see his sister standing, safe and unharmed, Night Caster passed out from magical depletion.
