The Darkness Consumes Everything

Chapter 1: The Beginning Of What Should Have Been The End

A pair of saddened silver eyes traced a large room; the figure behind them was shrouded in mist. A silver mist that shone with brightness, yet all the while danced with dark flames. The darkness of pain.

Inside the room, were bundles upon bundles of talking, laughing, smiling children. She couldn't take it anymore. They were all like her once. They were all so carefree, just worrying about their next test or their homework. All they would care about was grades and hanging out with their friends.

Wouldn't that be fun? To hang out with your friends once again? To be able to see them in anything other than your haunted dreams? A voice said tugging at her mind. The girl almost broke down, then and there. How could she have done this? It had been almost one thousand years since her friends had left her forever, and during that time she had lain dormant at the Galaxy Cauldron. So that when she awoke, the memories of her friends' death were still very fresh in her mind.

At first she did not know what had awoken her, all she had wanted to do was to go back to sleep where, even in her nightmares, she could still see her best friends' faces. A short while after her awakening she was transported, through a field of light, to this universe, a place where magic could run freely, and to a time period that mirrored her own before Chaos entered into her life.

Magic that could bring disaster in the wrong hands, magic that could bring joy and happiness in others. Magic none-the-less, only offered to the selected few who would be able to do something with. Become great, for good or for evil. And, unfortunately for her, darkness had just scored another point.

Chaos had been resurrected, taking over a vengeful, dark magic-users spirit, and giving it a body. This was something that she had to deal with. A part of Chaos, that monster who had destroyed everything dear to her, had shown it's ugly face to the world. She had to stop it, or else innocent lives would be hurt again . . .

She would never let that happen. Not again. Her dimension, her home, had been lost because she was not able to defend it. All those innocents had been lost to the Galaxy Cauldron. She had to help these people. She had to help these carefree people. So she forced herself to take an offer for a job in one of the most likely places that Chaos would attack. In fact he had already attacked there quite a few times, but only when he was barely possessing the soul of a dark spirit. Chaos through some devious plan had been able to collect several splinters of his original soul and amassed them into one darkly hate-filled soul.

This time he would be back at full force to destroy this place. This school, Hogwarts was it? No matter, it was just one more place to protect. And the easiest way to do so was inside the school. That's where the job offer came in. She had taken it as soon as she learned about it from just entering this dimension from a time portal. Well at least a week after she had entered the realm, after growing accustomed to these people, these 'wizards' and 'witches' habits and customs.

Now she was the brand new Defense Against The Dark Arts teacher. A lot of good that would do her. She had probably fought more evil in one millionth of her life than any of these people would ever face in their entire mortal lifetimes. The students sure were going to get a large surprise when they saw her. Thinking of this almost made he smile. Almost. Her lower lips twitched and that was it. The small tilt of her lips was soon replaced with her usual blank expression that she always wore.

The figure soon snapped out of her reverie when she noticed that the Great Hall had grown silent. She could tell that they were waiting for something, and they were. An elderly woman walked out from a side passage to the Great Wall, with a dusty old hat in hand. The hat seemed to radiate power almost as if it was someone's old subspace pocket. But besides it's strong aura, it held something else. It seemed to hold on to many peoples' memories of good and bad. Definitely something to watch out for if you wanted to conceal your identity. She'd have to remember never to try it on.

The hat soon began to speak:

'I shall tell you unto which house you shall be received

I shall tell you what your destiny can show

You will no longer be deceived That is one thing that I know

Many millennia from today

A fair Queen did say,

"Let them know what we can do

Let us prove ourselves to you."

The gifts were brought

And distributed as such

And nothing could compare to their trembling touch

Hufflepuff gained love and friendship to last

Ravenclaw gained knowledge and could learn things so fast . . .

Slytherin received slyness and a temper

While Gryffindor gained courageous zephyr

But what of the one who gave all these fine gifts?

She departed from Earth for her final bliss.

But once again darkness rises

Awakening her long slumber.

Our heroine has many surprises

She is waiting to uncover

I warn you fair people

Your time has grown short

It's not likely she'll free all

Know who you support

I see all

And know all

So heed my fair warning

And maybe you will live

Through the distort'

The room grew silent. Not even the teachers were clapping, or moving very much for that matter. The only person inside the whole castle, ghosts included, who wasn't slack-jawed with astonishment, was the mysterious figure among the shadows. And this time the slightest trace of a smile did touch her sugar pink lips. But once again disappeared almost an instant later.

That hat was awful at creating lyrics, although she had to admit it really did quite a good job in terrifying the new students. Those poor little children were all white as the ghosts who were floating around all over the castle. In fact it looked as if some of them had been so nervous and scared that they had fainted standing up. Or at least that's what it looked like from her place in the sidelines. Maybe a few had really fallen asleep.

The sorting passed quickly, and soon afterward the headmaster, Dumbledore, stood up to address the students.

"I would like to thank most of you for returning this year. After the terror filled year we had last year, I was afraid that I would lose many of you as my students." Said Dumbledore a merry twinkle in his eye.

"I am glad that I can be returning as headmaster as well, during the summer I received many letters from quite a few disgruntled students about my . . .temporary replacement." Dumbledore looked down at the hall with a light twinkle in his eye.

He continued with, "As I know that many of you have complaints with The High Inquisitor, I would ask you to settle them out of school. But the news that our dear Delores Umbridge will not be returning to us this year may brighten your day. Please, as a note to all years, not just those in the first five" Dumbledore gave a disapproving look to a group of three students in particular, "The Forbidden Forest is forbidden for a reason; please do not attempt to travel inside."

"And as a final note, I would like to introduce to you our new DADA teacher. Please everybody welcome Miss Serenity Cosmos!" The lone figure stepped out of the shadows where she had been patiently waiting. And as soon as the student population laid eye on her, their eyes popped straight out of their heads, mouths dropped to unimaginable distances, and the clinking of metal could be heard as drinking cups met the cold stone floor.

A/N: Hey Guys! I started this story when I was still in Middle School and haven't really thought of it much since then. Now I'm half way through college and I thought I would try and give it another try, so I've gone back over with a few edits. I'm going to be traveling outside of the U.S. so please bear with me if I have slow posts. I will be adding more chapters than the original story so hopefully that will raise your interest. Thanks and please R&R.
