Long ago there was a prophesy that two children would be born to the royal family as always, one for the sun and one of the moon, but one day, a third will be born. A child of of the stars. It was said that this pony would live in trial and that others would seek to harm her. When the filly was born her parents, Astrum and Caelus, they hid her out of fear for her safety, not even telling her sisters if her birth. This pony's name is Midnight star.
"She is not old enough Caelus, maybe later,"
"She should know, I fear for her too but it's not right to keep this from her,"
"I know its just..."
"It is all right, I understand. " Midnight had heard similar conversations many times while eavesdropping on her parents but she still didn't know their secret. She went to her room to think. Still a filly, Midnight star was isolated from the world and longed to see it but wasn't allowed. Suddenly two ponies ran past her open door. The first was a brown stallion with a dark mane, the second a silver Pegasus pony.
"Hello, are you new? Do you work here?"
"Oh!" The stallion cried noticing her and stopping abruptly, "Yes, we, uh... are fixing a broken pipe, that's it a broken pipe,"
"Doctor it's getting away, come on!"
" Coming Ditzy! Sorry got to go, pipe's acting up," Midnight was no fool and he was obviously lying so of course she followed him. She caught up to them in the throne room where a large... something stood. It looked sort of like a...
"A manticore! Fancy that! First magical ponies and now this, it keeps getting better!"
"Doctor, now is not a good time,"
"Oh, right. Manticore, we mean you no harm, come with us and we can take you to a safe planet," the thing roared and lunged at him.
"Right then, Ditzy! Get everyone away from here, I'll get the manticore, hehe! Manticore," the grey pony, Ditzy came over to Midnight and told her to hide, leading her away. She decided this was a good time to listen and hid in a closet. There was something in there. It was large and a deep blue in color, sort of like her mane. Her mane was Mazarine blue and pale yellow and her coat was a silvery blue. The box read 'police Box' and, hearing crashing outside, she entered the box.
"Well, that worked out well!"
"If being almost killed and wreaking half the palace is 'well' then yes, it did work out well,"
"Oh come on, it wasn't that bad,"
"Fine, I guess,"
"Excuse me, is the monster gone?" The Doctor looked stunned when he saw me under a bench in his box, which was much bigger on the inside.
"Yes... how did you get in the TARDIS?"
"Maybe you forgot to lock it,"
"Did not! But how..."
"I just opened the door,"
"See, it wasn't locked,"
"Yes it was! The TARDIS doesn't open for just anybody,"
"hehe, yes, anypony," Ditzy sighed in exasperation. "The point is the TARDIS must have wanted her here or she wouldn't have opened. You, little pony, what's your name?"
"I'm Midnight star,"
"All righty then, would you like to come with us?"
"Doctor she's only a filly!"
"The TARDIS let her in! She..."
"Do you hear that?" They stop to look at the filly "The music, your box is singing,
I awoke from a deep sleep to find myself in a rundown abandoned house, my home now. It had happened so long ago but I still dreamt about the night he took me away in his magic box to show me the universe and all the days after that until the one where I had to leave him. I looked at my cutie mark, a ridiculous name. I had been happy to get it but it had come with a price. My ability and my identity must remain a secret. Looking around I noticed a bag in the corner. Almost empty. Sigh, I guess I'd have to go into town today, oh well. Grabbing my cloak I left.
