Well, here's something I wasn't considering doing until recently. Until now, my only dalliance with A Song of Ice and Fire or its TV adaptation Game of Thrones was a one-shot crossover with Black Lagoon, called Roanapur's Imp. However, I realised that, with some tinkering, I could have at least one character from the series end up in the Potterverse, though it requires some rather convoluted stuff to happen. Namely, Daenerys Targaryen, prior to the start of the series.

I also chose to cross this over with Game of Thrones deliberately for two reasons. Firstly, I hadn't done a crossover with Game of Thrones before (my one-shot is marked as a crossover with A Song of Ice and Fire). Secondly, and more importantly, Dany is 16 at the beginning of the TV series according to research, as opposed to her age of 13 in the books, meaning less squick involved. She, and Harry, will be about 15 at the start of this (it's another Year 4 book, once they get back to the Potterverse, with the ages bumped up a year), and the story will be finished in time for Dany and Harry to get involved with the events of Game of Thrones, should I decided to do a sequel...and assuming this gets published as a story at all.

This is actually mostly based on my 'Misery Loves Company' challenge, mixed in with a partial response to whitetigerwolf's 'Animagus Lover' challenge. Anyway, enjoy.

A UNION OF DRAGONS

CHAPTER 1:

A MEETING OF DRAGONS

It took all of Illyrio Mopatis' not-inconsiderable influence to prevent the rumours from spreading too far. While he was in alliance with the infamous Master of Whispers of Westeros, the eunuch Lord Varys, he knew better than to allow information to spread without his leave. Varys was one of the few who knew outside of Pentos, and even within Pentos itself, the amount of people who knew about the secret within his manse was a small amount.

Still, rumours were hard to quash, and indeed, the very act of quashing them was akin to popping a pimple on the face, likely to cause the rumours to spread and multiply. Thankfully, the rumours were not enough to cause certain opportunists to come out of the shadows. What Illyrio had in a special room, deep beneath his mansion, was worth a king's ransom many times over. But he knew that he needed to save it for some very special guests who had been invited to stay with him.

Namely, two of the last remaining Targaryens.

After Robert's Rebellion, the surviving Targaryens could now be counted on a single hand. Aside from the two who were coming to see him, he knew, through Varys, that a third worked as a Maester for the Night's Watch at the Wall in the North of Westeros. If any others were left in existence, then they had the good sense to hide far better than these two did: Robert Baratheon's sheer hatred of anyone with Targaryen blood was stronger even than the man's taste for hunting and hedonism. Illyrio couldn't exactly judge the man on hedonism, but Robert was infamous for his lack of good grace and elegance.

Then again, it wasn't like these last remnants of the Targaryens were any better, according to his sources. The girl, Daenerys, was something of a non-entity, apparently, due to the overbearing influence of her brother Viserys. Beautiful, but rather passive.

Viserys was another matter. Unlike Daenerys, who had been born on the run from Robert's wrath, Viserys was old enough to remember what being part of royalty was like, and his anger and resentment had festered over the years. He was mocked throughout the Free Cities as the 'Beggar King', due to having to live off the goodwill of those in power. Unfortunately, he also seemed to have something of his father Aerys' madness and cruelty, being aggressive, haughty, and impulsive, forgetting that a prince without a throne had little authority, if at all. That he hadn't been murdered by now was a miracle in of itself, though not necessarily a good one.

Still, Viserys had responded to his invitation, sending back a haughty and, frankly, condescending missive that was nonetheless well-written, with the Beggar King deigning to accept Illyrio's invitation. They were due later today. And when Viserys saw the gift he intended to give to him, Illyrio knew he would have the spoilt royal brat hooked.

Which was why he entered the room where he kept his secret gift, one he had found a few months ago not far outside the city, one he had managed to get to secretly before anyone else. A creature not seen for over a century. It had been unconscious, exhausted. He still kept it confined, not willing to take any chances. But Illyrio was certain that the creature was intelligent. He sometimes spoke to it. Like he was now. Not willing to speak all secrets to it, but still, he felt like it was a confidante of sorts.

He sat down on a stone bench, to the side of the chained beast, and remarked, "Your new master arrives later today."

A slit-pupiled eye opened, and glared at him balefully. The one with the peculiar scar above it. It was a most brilliant emerald colour. The lips of the beast drew back over vicious, sharp fangs, and a low, quiet, but menacing growl echoed around the underground chamber.

"Now, now, none of that," Illyrio chided gently. "Your restraints are a regrettable necessity. Personally, I would prefer you to not be kept underground like this. A magnificent beast like yourself deserves to be shown to the world as the wonder you are, to be treated in accordance with your majesty. Sadly, reality is a cruel mistress, and I am forced to retain you as a bargaining chip of sorts. Your destiny is now to bring glory back to a diminished line, to be their steed as they burn through their enemies."

There were times when Illyrio imagined that the beast could speak, the last couple of times he had visited. But what he heard next was no imagination. It was hard to discern, partly due to the band of metal keeping its jaws mostly closed (leaving enough only for it to be fed with extreme care), and partly due to the inhuman shape of the mouth…but he heard words now, spoken in a deep, bass rumble. And what they said shocked him. Not surprised him, but he was shocked that the beast could truly speak…and that could think.

"I…am…nobody's…pet…" The emerald eye focused on Illyrio. "But I…WILL…burn…my enemies…" The intensity of its gaze as it focused on Illyrio meant that the Magister was one of this creature's targets.

Illyrio fought down the urge to gulp nervously. Instead, he said, "That would not be wise. You forget who holds the keys to your release. You will be obedient, or perish should your value prove less than the trouble you cause. You may be powerful, but you are far from invulnerable."

A series of huffs emerged from the creature's restrained mouth. Illyrio realised, with a start, that the creature was laughing at him. It was part-mockery, and part-weariness. He knew the creature had to be young, given its size, and yet, there was something old, or at least experienced about it. "…If HE…couldn't do it…what makes you…think YOU can?" it growled. "I will…escape…Illyrio Mopatis."

Illyrio scoffed with a confidence he didn't truly feel. "I have every confidence in my blacksmith and lockmaker. And I find you to be a rather dull conversationalist anyway."

Once more, the huffs echoed around the underground room, and Mopatis decided to leave. NOT retreat, no matter how hurried his walk up the stairs was. The laughter, however, followed him up the stairs…

It was later that afternoon that Illyrio had welcomed his new guests. They certainly had the silvery blonde hair and violet eyes that marked the Valyrian blood the Targaryens had. They were very different, though, and not just in terms of gender. The reports Illyrio had about their respective temperaments, sadly, seemed to be accurate, and he knew he would have to draw on his diplomatic skills to keep Viserys from having a hissy fit every time something didn't go his way. He was a spoilt child whose hardships hadn't tempered his character, but worsened it. And Daenerys was a timid mouse. A beauty, and an excellent bargaining chip to be married off. Maybe to that Dothraki warlord Khal Drogo, which would satisfy Viserys' desire for an army to conquer Westeros with, but still, she had less fire and steel in her than a Targaryen should.

Still, he knew that Viserys would be potentially pleased with the gift he had been given, though he felt some trepidation about the matter. After all, if the beast proved recalcitrant, it may either harm Viserys, or Viserys would kill it in a fit of pique. Either scenario was immensely irritating, to say the least.

"And why has a gift for me been consigned to such a dreary and dull cellar in an outbuilding?" Viserys demanded imperiously as they descended the steps.

"A precaution for various reasons," Illyrio said smoothly. "Two are of considerable and equal importance. The first is that I do not want any damage done to my residence should something happen. The second was more of a matter of secrecy. I have managed to prevent rumours from spreading, but they may yet spread, and that would complicate matters."

Viserys emitted a rather disgruntled noise, but accepted it. Illyrio had even ensured that they were the only ones there, to ensure Viserys couldn't accuse them of attempting to murder them. "And what is this gift?"

"You will see, Your Grace," Illyrio answered, for what had to be the tenth time in half as many minutes. He kept his exasperation off his mien and out of his voice, though.

But they came to the room, and they saw what was chained and bound to the floor. The two Targaryens gasped in shock and surprise. But then, that was perfectly understandable.

After all, they were seeing a dragon for the first time in their lives.

The scales of the beast were pitch black, save for a jagged white scar above its right eye, looking like a thunderbolt. It was a little smaller than a horse, wings aside, and looked rather scrawny. Chains and bands of metal held it down, and a metal band around its mouth acted as a muzzle of sorts. It opened the eye facing them, the emerald orb peering at them balefully…though Illyrio seemed to note a brief moment of surprise when it saw Daenerys, a minute widening of the eye. Maybe struck by her beauty? Perhaps there was some truth to the old fairytales of dragons abducting beautiful princesses.

Once Viserys had recovered his wits, he turned to Illyrio, a pleased smirk on his face. "A very fine gift indeed, Illyrio. I presume the chains are a precaution?"

"Indeed, Your Grace," Illyrio said, thankful that the Beggar King didn't protest their usage. "We came across the dragon just outside of Pentos. Mercenaries loyal to me found it, comatose but alive. I had been negotiating for the purchase of fossilised dragons' eggs from the Shadow Lands beyond Asshai as a gift, but this rather serendipitously came to us."

Viserys nodded, and then approached the dragon. Despite his arrogance, he did so with considerable caution. "Strange," he mused. "I had dreamed all my life of obtaining a dragon. But the reality does not quite meet the dream. Was it like this when you found it?"

"Yes. By what accounts we have found, the dragon is an adolescent, or at least the equivalent. I should also warn you, Your Grace, that the dragon is intelligent."

Viserys scoffed. "Intelligent? As in able to think and speak? Don't be absurd. They're beasts."

"If I…am a beast…what does that…make you?"

Viserys all but leapt back. "It spoke!"

"Yes, I spoke. And so…did you." The dragon glared at Viserys. "And I will…not be…your pet."

Viserys, true to form, sneered. "How dare you speak back to me?! Even if you are capable of speech, your place is as my mount, as I take back the throne that is rightfully mine! You have no say in the matter!"

Daenerys watched as the dragon…well, awoke the dragon, as her brother put it so often. She feared it, and yet, this bound dragon with those emerald eyes was baiting him! She knew he would punish the dragon mocking him, just as he punished her for slights both real and imagined.

She wished that her friend was here. True, said friend was imaginary, coming to her only in her dreams. A baseborn boy, black of hair and green of eye, wearing glass lenses on frames. A boy who learned he was a wizard, so he claimed. He had been a major comfort to her during the Targaryen children's hard times on the run. The stories he told of his life had helped give her some peace.

But no, he was a figment of Dany's imagination, one that came and went like the wind. He would never be able to save her from her brother and his ambitions. She knew now what kind of person he was, that the brother she loved and who loved her in his turn had died in increments, leaving a sleeping dragon that did not love, just rage and hate.

The dragon lying here was magnificent, though to hear it speak was a surprise. They never did in the histories. Fairytales were another matter, of course, but this one could. And it hated her brother.

"Oh? I don't have…a say?" the dragon rumbled. "Let me guess…you will say…something like…hmm, 'just wait till my father…hears about this'? Oh, wait. Your father's dead…Viserys Targaryen. And you are…your father's son."

"Silence!" screamed her brother. "I will not hear another world from you, beast, unless I order it!"

"Too bad…because I have…another word…ALOHAMORA."

The word was alien to Dany's ears, and yet, suddenly, locks suddenly sprang loose. The dragon shrugged off the chains and metal bars, shaking them off like a dog shaking off water from its fur. As it rose, it said, "It took me…months…to remember…myself. I will not…be your pet. Now…GO!" A brief blast of flame that singed her brother's hair punctuated this.

Viserys immediately fled, pushing Dany behind him to act as a human shield, causing her to stumble and fall near the dragon. The Magister seemed more inclined to try and help her, until the dragon reached over with a clawed hand, and grabbed her leg, pulling her towards it. "Dany is MINE!" it snarled.

Dany was confused. The dragon had called her brother by name, now that she came to think about it, but maybe Mopatis had mentioned their names before. But how could it know her nickname?

The Magister fled up the stairs, though not before saying, "I doubt you can escape yet, even with fire and flight." Then, he left.

At that, the dragon closed its eyes, and then gently let Dany go. For some reason, though, she didn't scramble away. Perhaps it was because the expression on the dragon's face was no longer fierce and furious, but rather, tired and regretful. "I'm sorry, Dany," it said. "I didn't want…to hurt you. But after…what you told me…of your brother…I thought you…were a dream…"

Suddenly, the dragon began to shrink, the scales changing to pale skin and dark, tattered robes, the figure becoming that of a boy of about her age, fifteen. The wings receded, as did the tail. The eyes remained the same, more or less, having the distinctive slit pupils of a dragon, though they were behind askew lenses. A mop of messy black hair sat on his head. His face looked haggard and drawn.

Dany, however, knew his face. It had been somewhat less haggard, true, but she knew it. Especially the scar that snaked its way out from beneath his hair. But it was impossible. He couldn't be here.

"…Harry?" she asked, scarcely daring to dream that it was real. "Is that truly you I see before me?"

He nodded, and held out his hand. "We've got to get out of here. I'll explain what I can later…though I don't know half of what's going on myself. Please, Dany…trust me."

After a moment, Dany took his hand. She was surprised at how readily she made the decision, considering she was running from her brother, from comfort and safety…but she knew that Viserys would be back soon. And despite him only existing in her dreams until now, Dany realised she could trust Harry more than she could trust her own brother.

And she thought something that she would hold as a standard in another time: If I look back, I am lost.

"Hold tight," Harry said. "I can't remember the last time I managed this."

Dany wondered what he meant, before she felt a strange sensation, as if she was being squeezed through a tube, taking her away from that outhouse basement in Pentos…and into something new…

CHAPTER 1 ANNOTATIONS:

So…Harry's a dragon, and Daenerys Targaryen was his imaginary friend. And vice versa. Don't worry, more will be revealed in due time. And they'll be heading back to the Potterverse before long, which is where most of this story will take place.

Now, Dany's character: she may seem OOC, but keep in mind that there's two main factors involved. The first and most important is that this is Dany before she toughened up after being married to Khal Drogo. But on the other hand, she's had Harry as an imaginary friend, and that has changed her character a little. Don't worry, we will see a version of the Khaleesi emerge.

No numbered annotations this time.
