Taster book of sorts IDK

I need a judgement

So...

Uh...

At my school, they're doing a competition. I don't know who they are but...

*ahem*

 Write a short story, including the word 'space'. I want to take part. And I've written at least three or four stories.

I narrowed it down to two I like a lot, but I can't really decide if I should use one of them, or write another based off my sister animation (the animation will be in the media)

So....

Stories :D

I had tried to think of another way of this. You knew I had spent every day before you died thinking of a different outcome.

But there's no other way.

Do you remember ages ago, you asked if I could take you to see space? How I laughed at you, telling you this wasn't a Doctor Who episode? Then I had to take you out. You were so thrilled. You asked if you needed anything. I told you just your wits.

You climbed aboard so happily I was so reluctant to take you. The small, sleek shuttle I call my ship took us to the small, seemingly deserted moon. Jupiter's moon, Phoebe. You stepped out, face-mask on, eyes wide and searching. The stars always look best from here. It's the smaller bit of mercy I could give you.

You skipped away, across the dusty terrain. I watched you go, trying to remember that exact moment. Then I turned, climbed back into the ship and left you.

You noticed. A look of utter confusion, then betrayal and finally hurt flashed across your face. I look away, eyes on the reducing crack rather than the darkness emerging from the deeper darkness. I listen to the roar of the ship rather than your screams as the aliens ripped you to pieces.

Who thought that now, two years later, I would return, a Scourge of Time, and be surrounded by the same creatures that ripped you apart? I spot you. Your arms and legs are thin, needles emerging from the ends. Your skin is deathly pale, your eyes wide and black. You don't breathe anymore.

I fight you off. Your murderers lay around us, twitching, dying. You circle. Of course, it's not you anymore. It's one of them, wearing your body. But it's enough to make me hesitate.

You see the pause and lunge, claws out. I fire the gun that ended the others lives. It hits you in the chest, and your body curls.

But you hit me. The claws that had emerged from the ends of your fingers, tearing your skin have sliced my arm apart. I take myself back to the new ship, a bigger and more professional looking thing, trying to heal it. But, just like the tear in the sky, it keeps getting bigger and bigger until my whole arm is torn up.

I know what I have to do.

Putting the bandages down, I take the watch that was given to me when I became a Scourge of Time, and pressed the dial twice. With a slight woosh I'm back on earth, the day before you met me.

I follow you home, remembering your screams as you were torn apart. You notice me, see my bleeding arm, but panic and start to run.

Although it breaks my heart, I take my gun, aim and fire.

My arm goes back to normal just before the wound gets worse. Your brain won't be the same though.

First story is around 490 words.

Something was gliding in the stars.

It was weightless, but seemed to have the body of a man. Two arms were stretched to its side, head up, it's legs invisible from the trail following it. It raced though the stars, alone, searching. Two pinpricks of darkness were on its face, like eyes made from dead stars. Its body was golden, shining through space.

Then, out of no-where, another joined it. If the first was stunning, this one was petrifying. Its body was black, so dark it stood out from the void. Its eyes were silver, lit up and following the first. The two chased each other through the night sky.

It started off peaceful - just playful tagging. But then, the second got angry. It recklessly tore after the first, eyes burning red with anger. Stars burned as it flew through them on its fruitless pursuit on the first.

This chase lasted all night and well into the morning. By this time, all the humans had woken and were watched, worried as finally, the second caught the first.

As they drew to a halt, every human was watching - regardless of time zone. All TV's, all radios, all computers were tuned into the sky in Western Europe as the first creature withered in a silent agony.

And then, in a burst of sparks, it went out.

The second hovered nearby for a moment, watching with every human as the sparks of the first fell to earth, like teardrops. As they fell, the world became darker and darker. The sun was drowned out by the sparks, until it was completely hidden like in a solar eclipse.

The earth was silent as the planet went dark, eyes watching the second creature rejoice in the sky.

Then it jerked, as if in pain. No-one cried out in fear or worry as its eyes widened in panic, and no-one worried as it was blown away, bit by bit by a unseen wind. One by one, the stars went out, dying as the first did.

Only when both the creatures from the sky were dead did the world stop spinning, fly out of orbit and sail through the galaxy. Only when the seconds black dust had settled did every human die out, slowly at first then all at once.

The planet kept on hurtling through space without a axis, without inhabitants and without reason until it gets sucked into a black hole, obliterated and torn apart, eventually just scattered dust, one dead star in a galaxy of others.

And that one is around 450. This was inspired by a book cover I have at the moment. It's a good story.

Or I could write a prequel to CrowSnakes (My sister)'s animation. She's given me permission. 

What do?
