"He's like fire and ice and rage. He's like the night and the storm in the heart of the sun. He's ancient and forever. He burns at the centre of time and can see the turn of the universe… and he's wonderful"

But who is he really?

I am Aine Windsinger, a companion of the mysterious Doctor, a time lord who travels in time and space. I've been travelling with him for five hundred years, he says. But it seems like only a day has passed since we met.

It happened by chance. The chance that a butterfly might collide into a tree ten thousand metres tall, the tallest tree in the world, to which it is so insignificant to, and reach the top.

I was climbing stairs on the Eiffel Tower, as I was chance to bumping into a tall, lanky man with a blue suit, red converse shoes and thick glasses teamed with greasy brown hair.

He looked like he had seen the stars for the first time, enjoyed the taste of too much wine. He was drunk with excitement, and I did not know what for.

Stuck for a whole day in a city I hardly knew, I decided to follow this excitement-loving man to the top. Breathless and tired, I decided to take the lift.

When I took the lift to the top, he was already there.

"How…?" I muttered, but the man seemed to hear me.

"I've done a lot of running in my life" he explained, "I've been everywhere, seen almost everything, but nothing"

I squinted, against the setting sun and confusion of this man. He spoke as if he knew everything, but he had admitted he didn't.

"Why were you running?" I asked, wondering.

"Practising"he replied, "and I've never been at the top of the Eiffel Tower at sunset"

"Practising? Are you, what, an athlete?"

The man laughed out aloud, a huge grin spreading across his handsome face, "You know, in my nine hundred years I've never been asked that. Never." He continued to laugh and gestured to himself, "Do I look like an athlete?"

Abashed, and not sure I enjoyed him making fun of me, I replied, "I guess not"

From then on, we have been inseparable. Hand-in-hand on each new adventure, leaping from star to star, galaxy to galaxy in the TARDIS which has become my home.

Until now.

A/N: Sorry I changed her name... It used to be Katie, now it is Aine. You'll find out why later on. Thanks for reading!
