Disclaimer: Don't own. 'Nuff said.

Author's Note: If anyone will write a 'House, M.D' crossover with anything (preferably 'Scrubs' because I had a dream about that and it was so cool), I will review every chapter like clockwork.
I would do it myself, but I'm in Australia (there you go Draconian Mistress, you have your answer), and it hasn't been on long enough for me to get a feel for the characters.
I might try when I've finished writing this story, I'll have time then.

The Tales of Werewolves
Dragon Parts in Potions

Dom struggled to open his eyes fully. Everything was blurry, and his eyes were watering for some reason.

He took a shaky breath and he tried to figure out what had happened, and what woke him up.

He could feel his every vertebra and concluded he was in snake form. He had the taste of blood in his mouth, and hoped it was his own.

Whoseever it was, it was making him hungry. Squashing the urge, he yawned, feeling his jaw unhinge, then hinge back as he did.

He focused on figuring out what had woken him, and came to the conclusion that it was the vibration from approaching footsteps.

Making a quick decision that no one would be able to see him, he tried to transform.

It felt like he was being squeezed and that his skin was peeling off him. He blacked out again.

Everyone rushed around Grimmauld Place like mad men. Flames burst in the fireplace and Harry and Draco stepped out and ran into the other room where most of the people were.

Draco, holding Jasmine close to his chest, went up to Remus. "Which room is he in?"

A few words from Remus, and the passing over of the now crying baby, the two newlyweds were off and up the stairs. The stopped abruptly in front of a bedroom door, and pushed it open slowly.

Dom was sitting up in his bed, vomiting blood into a smallish bucket, which was on his lap.

Harry crossed the room and sat on the bed. He rubbed Dom's back while Draco searched for his wand. After Dom had finished had leaned into Harry, Draco muttered a spell and stuck the magical end of his wand into Dom's mouth.

It beeped. "You've got a fever." Said Draco, stating the obvious.

"I didn't want to go to sleep until you both got here." Dom mumbled hoarsely and moved so he could snuggle into his pillows. Harry tucked the doona and blankets tighter around him and stood.

"Come on, let's go."

Dom waited until he couldn't hear any footsteps at all before daring to open his eyes. He slipped his glasses on and went to get dressed.

He decided on black denim pants, a black turtleneck and scarf, as well as a Copper, Dragonskin jacket, which just reached his knees and came from a Peruvian Vipertooth.

He put on light, almost ballet-like shoes and put a waterproof/heating charm on them, before extending his wings throwing on a disillusionment charm, he opened the window and flew out into the night.

Freezing air whipped at his face, and small snowflakes splattered on his glasses, but Dom didn't stop or slow down. He headed towards Diagon Alley, and more accurately, Knockturn Alley.

His body was so cold, but his head was so hot, and he had a headache that made him feel like throwing up again.

He went lower, about two feet from the ground, as houses started to appear around the place.

Dom had been wondering how to get a hold of what he needed to free Sirius, but if he didn't soon, he would die. He knew he would. But he wasn't going to go down without a fight.

All rules were out the window now, and had to do this anyway possible. As he came to Knockturn Alley, he closed his eyes, felt his fangs grow until they stuck out of his mouth even when it was closed, and he let his Vampire side take over.

It was easier then he thought it would be, but going back and suppressing the feelings would be a hell of a lot harder.

He landed, undid the disillusionment charm and walked down into the Alley. Unlike Diagon, Knockturn was still full of life even thought it was one thirty in the morning.

Dom headed straight into 'Borgin and Burkes' then he walked right up to the counter and thumped as hard as he could in its surface.

Borgin appeared in all his oiliness. "Yes, what?" he asked rudely, skipping the politeness because he didn't recognize the young man in front of him.

Dom used his finger to indicate Borgin to come closer. "I need to see your ingredient range."

"We don't do potion ingredients."

Dom moved his face a bit closer to the oily man's and tried not to breath in the foul stench. "I know you do, don't lie to me." He slipped off his glasses and fixed his eyes on Borgan's. "You know who I am?"

Borgan backed away, and was to scared to run, but he managed to nod slightly. "I heard rumours he had a son." His voice broke with fear. "I-I'll show you to the room. Forgive my rudeness, please."

They went around the back of the shop, down flight of steps and into a large room filled with objects, large and small. "I can take it from here." Dom snapped.

"With all due respect," said Borgan, bowing, "It's policy that I must stay with any customer if they are in back. T-That includes yourself."

Dom turned his head to look at the shop owner for a second or two before turning his whole body. "I don't think so." He smiled, making his fangs even more noticeable, his eyes glowed bright scarlet for a second.

He took a step forward.

The eye of an Antipodean Opaleye Dragon was in the corner. It was Large and glittering multi-colours. It had no pupil, and was considered one of the most valuable objects in the magical world. It was also illegal to use.

On a shelf sat a leather pouch with five large black stones in it. The insides of the stones swirled around, looking like a black hole.

A small container was sitting the skull of a Centaur. It contained grinded horn of the Romanian Longhorn dragon.

Plants off all shapes and sized grew on the far wall, most in a hydroponic chamber, but a few were snaking their way up the wall. Many had flowers on them, but one in particular stood out: The Alpine Star.

The liquid from a pensieve was in a bottle similar to a beer bottle.

1 Opaleye eye, 3 Stones of darkness, A pinch of Longhorn horn, 12 Alpine Star petals, 50ml unused Pensieve water.

Dom crossed them off his list, and shoved it back into his pocket. He swung the bag, which had the shrunken ingredients, over his shoulder. He grabbed something off a shelf on his way out and put it in his pocket.

He stepped over Borgan's dead body, and avoided the blood pouring out of the two marks on his neck. His eyes were staring at the roof blankly. Dom didn't say anything as he closed the door behind him.

It would have been very easy to have made a final comment to the body, something along the lines of, 'I assume these are on the house', or something similar, but he couldn't bring himself to say it.

If he said something it would have confirmed the kill as a murder, not just as manslaughter. The difference between them was malice afterthought, and he didn't have any malice afterthoughts, are any thoughts at all. It was simply, removing an obstacle, not murder.

He licked his lips and sucked on his fangs, which had shrunk slightly. He walked into Diagon Alley and headed towards Gringotts.

10 melted Galleons, 3 drops Goblet of Fire liquid.

The goblet was in vault 9972, a fact known by extremely few people knew. There wasn't much guarding it. All he needed was a goblin's finger to open the vault, and he had taken one from B&B, and he had it in his pocket.

He transformed with surprising ease and slithered along the wall undetected and hid under a cart, which he head a goblin say was going to vault 10,000. It was a Malfoy vault. One Lucius had signed a contract about, preventing Draco to touch it.

Dom could smell the stink of arrogance from the longhaired ex-blonde, whose hair had now turned white. Draco and Harry would often joke about it.

Dom closed his eyes and lent his coffin shaped head against the cart. He squashed the need to cough. Now that he had nothing to take his mind off it, he realized he still felt weak and sick.

The movement of the cart wasn't helping either.

It screeched to a halt and Dom slithered off carefully, keeping to the shadows so he wouldn't be seen. He went down 28 vaults, focusing on getting there and still having enough energy to transform back.

When he got there he focused on the fact that if he could do this, he would get Sirius back. He repeated it in his head like his own, personal mantra. Finding hidden strength in the thought, he transformed back into a human.

He pulled a goblin finger out of his pocket and stroked the door gently with its nail. It opened. And Dom snuck in, passing the sleeping troll and pulled his clean handkerchief out of his pocket, opened the case, and dipped the corner into the goblet.

He folded it with the wet corner in the middle and put it in his pocket, before transforming then slipping back out and into the cart again. He was yawning the whole way back.

Mundungus, on the Order's orders, went into 'Borgin and Burkes' and rung the little silver bell on the counter.

After waiting a few minutes, Dung had enough and went around the back uninvited. He looked in all the rooms, but paled when he came to the one with the potion ingredients.

He crouched down and gently moved the head of the corpse to reveal the neck, and the two blood covered bite marks.

'Shit. Dom's loose and on a mission.'

Dom's slipper-like shoes made no sound on the Ministry's floor as he made his way down into the Department of Mysteries, his bag still over his shoulder.

Very few people were still around at this early hour, so it wasn't as much trouble as he thought it would be to sneak around.

In the large circular room, he didn't close the door he came through, knowing what would happen if he did. So he left it open and chose the seventh door to the right, where his instinct told him the Veil was.

Sure enough, there was the room, in all its glory, exactly the way Harry had described it. Dom stood on one the steps going down into the pit. He saw the archway, and the veil. He walked around the rectangular room so he could see it at all angles.

He pulled all the ingredients out and enlarged them all to their normal sizes. With his nails he cut the top third off the top of the eyeball, and tipped the liquid and mush out. He put the Pensieve liquid in it, and then filled it up with normal water.

He got his handkerchief and wrung the wet corner out over it. He added the rest of the ingredients and stirred it with the tip of his wand, muttering a spell as he did.

After five minutes he froze the mixture solid, and then lit a fire under the eye. Now all he had to do was wait until it was finished melting.

He lay on the steps, locked the door, and closed his eyes. He heard the ice crack, and decided to set his wand so it would beep when it had melted, just in case he fell asleep.

He fumbled with his wand as he set it. Since his hands were shaking, and his eyes were closed, it was harder then he anticipated. He was so tired it felt like his eyes were glued shut, even thought it was impossible, that's what it felt like.

He eventually got it though, so he put his wand in his pocket. Closing his eyes, he wrapped his arms around himself and shivered. He coughed a few times, his throat was burning, and he also felt like vomiting from the blood he ate.

Dom scolded himself. He should have known better then to each suck a large meal when he was still sick. He cringed when he heard his stomach bubbling, and swallowed thickly when he felt something rise in his throat

He refused to throw up. Mind over matter. All he had to do was focus, which he did.

Slowly, with one hand on his stomach, trying to get it to settle down, he managed to get into a light sleep.

A/N: I see the end on the horizon. A few chapter away I think.
