….

In all the far reaches of the world, all eyes were upturned towards the heavens, where a red comet blaze brightly.

A scarlet and circular smudge with its long tail leaving pink, orange, yellow streaks on the azure sky.

And at night, it burned like a bleeding star.

Many thought that it was a sign from the Gods.

A sign for those who thought they knew everything.

But they are wrong.

For it was his sign.

It herald of his rebirth…

Of his coming into that world torn by war and internal disputes.

….

"It's time," those were the words spoken to him in the pitch-black darkness, where he lay asleep.

Suspended in time for a purpose.

For how long?

He did not know.

Perhaps he had been there longer.

"It's time for you to rise as promised, my master."

….

He woke to the scent of smoke and fire and ash, to the rough texture of sand against his bare skin, to the sounds of audible hissing close to him, and also to the sensation of fullness in his chest.

His lids fluttered open, and was greeted by the sight of a black and red creature, small with its orange-red eyes staring straight at him.

He stared at it curiously, and heard other hissing noises nearby. He felt movements on his leg and on his arm where he heard the sounds had come from.

However, before he could look into it further, he was suddenly assaulted by flashes of images, too fast for him to grasp that he was sent reeling from the unexpected onslaught.

….

Memories. He later realized as the scenes played out in his mind's eye. Memories that aren't my own.

They were memories of someone else's life.

Of a girl with silver-blonde hair and lilac eyes.

This wasn't his body.

No…

Not his.

Hers.

It was the girl's body.

From what he had gathered of the memories he had seen.

The girl was Daenerys Stormborn.

The Targaryen Princess.

He was born in smoke, and she, in salt.

He was ice, and she, fire.

He was Harry Potter, and she was…

Daenerys Targaryen.

Together they were the Prince that was Promised.

Author's Note:

Short explanation why "Harry is Ice and Dany is Fire," You can see it from this passage.

"The way the world is made. The truth is all around you, plain to behold. The night is dark and full of terrors, the day bright and beautiful and full of hope. One is black, the other white. There is ice and there is fire. Hate and love. Bitter and sweet. Male and female. Pain and pleasure. Winter and summer. Evil and good. Death and life. Everywhere, opposites. Everywhere, the war." - Melisandre, Book Three: A Storm of Swords, page 348. (by G.R.R Martin)

Since Harry is the Master of Death. I'll just represent him as someone who has the song of ice, while Daenerys has the song of fire. You get the gist of it. I hope you didn't get confuse.

"It is written in prophecy as well. When the red star bleeds and the darkness gathers, Azor Ahai shall be born again, amidst smoke and salt to wake dragons out of stone." - Melisandre, Book Three: A Storm of Swords, page 349

"He is the prince that was promised, and his is the song of ice and fire." - Rhaegar, Book Two: A Clash of Kings.
