A/N: A new story, this time crossing into the realm of Westeros, I've tried very hard on this story and trying to incorporate two worlds together is very hard. I can only hope it pays off and is believable.

The prologue is of Aerys' pov, and hopefully sets the scene a little and gives a leeway into the story and type of world I am creating.

Enjoy~

King Aerys II Targaryen was once a handsome man, he had the traits of his house, the beautiful silver hair and the haunting purple eyes, he was strong and he was a good ruler. At first.

No one could pinpoint the exact moment of his decline into madness, perhaps it was his capture at Duskendale, or it might have been all the stillbirths and miscarriages his sister-wife suffered. They say whenever a Targaryen is born the gods flip a coin, on one side lay madness and the other lay greatness, and the world can only watch with bated breath as it lands. The gods are cruel indeed. All the realm knew was that King Aerys was mad and a propensity for burning people, no matter the crime, and his suspicion of treachery knew no bounds. His sister-wife received the brunt of his madness, he often sought her out after a burning, aroused and dangerous. He would hit her and bite her as he savagely took her, uncaring of whether he would hurt her. She was nothing to him. She had borne him another child, this one hadn't died, a boy who was named Viserys and Tywin Lannister had used the event to stage a tourney. Though Aerys had known why Tywin held the tourney and he was proved right when the subject of a betrothal between his first born and Tywin's daughter.

His eldest and heir Rhaegar had just reached ten and seven then, he didn't give the boy much thought and let him do as he pleased so long as it didn't disgrace him. He loved Rhaegar about as much as he loved his sister-wife – not very much. But that did not mean he would allow his son to marry Tywin's girl when he was approached about a betrothal. His son was the crown prince and Tywin was no more than a servant. No matter how much the girl claimed to love the prince and the tears she had shed when she found out about his denial of the match.

He had loved once.

A beautiful maiden from Volantis with fire kissed hair and the brightest green eyes he had ever seen, he had only been four and ten at the time, but the fire maiden had captured his heart and had never released it. She was named Lilianna, Lily he remembered she liked to be called, a beautiful flower to be sure and it suited her well. They had spent a month together, stealing kisses and making pledges of forever in the shaded areas of the hot city, but then he had been called back to his father's side and forced to marry his sister. It was not a happy wedding. Rhaella had loved another man as he had loved Lily and perhaps that was why he shunned her and loathed her so, for if she had never been born then he would have been free to marry Lily.

News of Lily's marriage reached him a few years into his own marriage and that was the first time he had ever burned a man, she had married another of Old Valyrian blood, James Gryffindor, and as he watched the green flames savagely eat the man he felt the pain in his heart dull for just a little while. When he took Rhaella that night, for just a brief moment it was Lily beneath him and he was tender, but then Rhaella's purple gaze found his mind's eye and he loathed his sister once more. When he received news that Lily had been gifted with a daughter, a beautiful child with silver and black tresses and with magical eyes, her mother's eyes, but they hold such haunting power Varys had told him and it was then Aerys began to take a better interest in his then five year old son. Rhaegar liked his books, a luxury that he cursed Rhealla for, but he was a good heir a fine match for girl with Old Magic.

But then news of Lily's death reached his ears and he forgot all about plans of betrothal, he didn't even remember the child of Lily existed, he let himself drown in the grief of his lost love. That was the moment he sank into his madness and welcomed it with open arms.

Rhaegar had been married to a princess, Elia Martell of Dorne, it had been Rhaella's suggestion and what a mistake that had been. The girl was useless. Sure she was pretty to look at but that was her only redeeming quality, like many of Dorne, she was rather loose with her affections and mannerisms but she was sickly and frail. She was no maiden when his son had lain with her. After the birth of his granddaughter – who took after her mother far too much to ever be considered Targaryen – she had eventually succumbed to terrible illness and was left barren. It was the last time he listened to his wife's suggestions.

The news of the latest tourney reached him, it was to be held at Harrenhal in honour of Lord Walter Whent's maiden daughter's name day. Naturally he was invited to go, he knew his son would be in attendance, but Aerys had not made a public appearance in quite a long time. He held no interest in tourneys nor in his people. He had half a mind to decline the invitation, his son would represent House Targaryen, what need was there for him to go?

"Titania will be in attendance no doubt your grace," Varys whispered coyly at his side.

"Who?" Aerys asked, what should he care about some insignificant faceless girl?

"The daughter of the late Lady Lilianna," Varys responded with a careless ease, "it seems House Gryffindor was great friends with House Stark, Lady Titania was given into their care when she was ten and has remained with the Starks since. She is one and five now your grace and, my birds tell me, she has inherited the strange powers of her house."

His sweet Lily's daughter, the one with the Old Magic, he recalled when he was told of the birth of the strange child. She was blood of Old Valyria and would've been a far worthier bride for his son than the Dornish whore. Perhaps he would attend the tourney after all, if only to see the child of the woman his heart still belonged to, even after her death.

"My son shall have his dear Lily," Aerys told Varys who listened with a quiet ear, "the blood will remain pure this time. You will give Rhaegar an heir won't you Lily?"

"You mean to wed the prince and the girl?" somehow the idea wasn't so surprising, in fact Varys had been expecting it. The Gryffindor girl should make a better queenly figure from what his birds told him about her, "that will anger Dorne your grace."

"Then Dorne shouldn't have given me such a useless cunt to wed my son with," he sneered, "my son needs an heir and for that he needs to remarry. What business is it of theirs?"

He wondered if the girl was as beautiful as her mother, perhaps he would sample her after his son had gotten her with child, he felt himself harden at the thoughts. Varys left him to his dark musings.

A/N: So it is set in Westeros, and there will be characters of the Harry Potter series appearing as the story progresses, though some without magic and some with special types of magic. I have up to chapter four so far, and let me say, it's been a nightmare and a pleasure to write.

I'm really interested to hear what you think about it.
