Chapter 1

"You sure this is where the address said?" Dean asked as they parked the Impala.

"Yes, I'm sure Dean. This is where the address is," Sam said annoyed as he got out of the car. "Should we put on the fed threads?"

"It's an old bookstore Sam," Dean whined as they crossed the street.

"So?" Sam asked, looking his brother over.

"We don't need the suits. The place is called Sirius Rarity. And serious is spelled wrong for god sakes!" Dean said.

They both stopped in front of the bookstore, staring.

"Just, let me do the talking okay?" Sam said as he opened the door and walked in, with Dean three steps behind him.

They heard the bell ring as they opened the door and looked around. It was old and bookshelves were everywhere, but instead of them being filled with books, most of them were filled with interesting looking knicknacks that drew Dean in immediately. There were interesting posters everywhere and it looked so neat but edgy, the boys were surprised.

"I thought you said this was a bookstore?" Dean questioned Sam as he walked toward the nearest shelf.

"I thought so too. Apparently it's not," Sam said as he looked through and found a few areas filled with books. "Well, not completely."

"May I help you?" said a voice behind them and the brothers turned around to see a brunette teenager, about sixteen standing behind them.

"Uh, yes," Sam said, walking toward the teenager, "can I meet the owner, uh. . ?"

"Amy," the teenager said, "and she's somewhere around here. New delivery and all, from England, so she's arranging it, but feel free to look around," she smiled.

"Uh, thanks," Sam said and he walked back over to Dean. "You wanna look around? Maybe we'll find something on the Mark."

"You go ahead, I'm gonna check some of these things out," Dean replied as he held up a box. "This thing here? It actually squirts goo over the loser. I am so getting this!"

Sam just rolled his eyes and went further into the store. While he was looking around, he got distracted by reflecting mirror and didn't notice where he was walking, and knocked into a ladder.

"AH!" someone shouted from it and before they could comprehend what was going on, they fell. Sam, hearing the shout looked and caught the person before they could hit the floor.

"I am so sorry, miss, are you alright?" Sam asked as he held her up.

Sam could feel how light she was and then was looking into a pair of shining grey eyes and he lost all the air in his lungs.

"Uh, yeah, you caught me in time. Thank you," she said breathlessly as she stared into his eyes.

"It was my fault. I ran into the ladder, knocking you down. Sorry," Sam said guiltily.

"It's really alright. I shouldn't have been doing this in the middle of the day," Izzy gave a small smile.

They stared at each other, surprised but drawn to each other until someone interrupted them.

"Ahem," Dean coughed behind them, and Sam quickly, but gently, put her down.

"Sorry again uh. . " Sam said looking at her.

"Izzy. Izzy Black," she said.

"I'm Sam Winchester, this is Dean," Sam introduced them.

"You a Brit?" Dean asked.

"Yes, born and raised," Izzy smiled, and Sam just stared as he was looking at the sun for the first time. "You lads finding everything alright?"

Dean elbowed Sam in the gut and he replied, "Uh, you the owner?"

"Yes, I am?" Izzy replied.

"Why is serious spelled that way?" Dean asked her quickly.

"Dean!" Sam said impatiently but Izzy just smiled.

"It's alright. I get that a lot. It's named after my father, Sirius, who's named after —"

"The star in the constellation," Sam finished.

"Exactly," Izzy smiled at him. "And a lot of these things are a rarity in America so," she shrugged and gave them a smile. "I see you liked the gobstone set?"

"This is pretty fuckin' awesome," Dean smiled.

"Well, we're actually here to ask you about something," Sam said, getting their attention towards him and a bit more serious, "our friend, Cass, he uh, told us about this store, and reading something about The Dark Mark and how to get it removed."

"It's just a story. Some old legends from long ago," she answered with a polite smile. "And I'm sure I have don't have those stories anymore, sorry lads, better luck next time."

"Are you sure? Can't you order another copy or something? Maybe another book you have here would have it?" Sam said desperately.

"I'm sorry, but those books aren't available anymore, but if anything else I can help you with I'd be glad too."

"Well you must've read it if you had it, any information you have would be —"

"I'm sorry but I don't know," Izzy told them.

If it was anyone else, they wouldn't have noticed the slight tense expression Izzy's face got before she gave them a breezy smile, but Sam and Dean did.

"Well, we'd believe that, if you hadn't gotten all tense now," Dean said as he walked towards her, "so start talking Audrey Hepburn."

"Audrey Hepburn?" Izzy said.

"Dean," Sam reprimanded him.

"Or what Mr. Winchester?" Izzy asked looking at him expressionless.

"Or this," Dean said, pulling his jacket slightly back and showing his gun.

"Dean, put it away. We need your help please, to remove a mark as well," Sam said apologetically.

"How did your friend, um - Cass, come across that information?"

"I'll go get him and you can ask," Dean said as left to go outside.

"Why didn't he come with you?" Izzy asked Sam.

"He's shy," Sam answered.

"So, you and him?" Izzy asked nervously.

"He's my brother," Sam immediately cleared up, "it's nothing like that."

"You guys seem pretty unreal," she snickered.

"Yeah, - um - we have that affect," Sam said as he stared at her.

"You're staring," Izzy muttered shyly and Sam blushed and was trying to stammer out a reply just as Dean and Castiel came back.

"You're Isobel Black?" Cass asked.

"Why, yes, I am. Excuse me," Izzy said as she and Sam got out of their moment.

She pushed them aside and walked back to the front of the store. "Amy, I'm gonna close up early today. You should go."

"Okay, see you tomorrow?" Amy said as she grabbed her bag from under the counter.

"I'll text you to let you know," Izzy said as she closed the door after the teenager and locked it.

"Why did you just do that?" Dean asked as she went behind the counter.

"So no one can overhear us, assuming this is something you want to keep on the down-low?" Izzy said as she pulled up a bag. "So, Cass? How'd you find out about the Dark Mark?"

"Well, there was a few people talking about in England and I questioned them a little, got my answers," Cass answered.

"They answered willingly?" Izzy asked surprised.

"They required...a little persuasion," Cass said. "But willingly enough."

"Alright then," Izzy said as she took out a few books and looked at the boys, "now show me the Mark you were talking about."

Dean and Sam looked at each other as Cass scrutinized her and Izzy sighed.

"A little faith please, I will try to help you as best as I can, but I can't if I don't know what I'm going to be working with," Izzy smiled, before Dean sighed and pulled up his sleeve of his many shirts, revealing the Mark of Cain.

They both heard her take a sharp breath as she touched it, "What is that?" Izzy asked as she touched it.

Dean saw Sam look frustrated as Izzy was near him and smirked.

"Well, this is bad. This isn't a normal mark. The Dark Mark was more like a print or tattoo. This, this is like a scar, like something carved it. It's not only on your skin, but it's imbedded in your blood as well," Izzy said as she pulled her hand away. "What is this, exactly?"

"It's the Mark of Cain," Cass told her.

"Mark of what?" Izzy asked, confused. "I've heard that before. An ancient ruin of sorts."

Izzy started going through some books behind the counter and flipping through books and looking through some old notes.

"This is just bloody fantastic," they heard her muttering, "I leave England because of this, and they start telling every fucking person they meet."

"Cass, how did you persuade the people?" Sam whispered.

"I might've used some mind control to find out, but it was only to find out about the Mark, nothing else. Her's was a name that was like imprinted onto a lot of their brains," Cass answered.

"Well, whatever it is, she's a babe. Look at her I mean!" Dean exclaimed quietly.

And they did. Her black hair hung till her waist, messy as it could be. Her eyes, as Sam had seen them up close and personal, were a dark grey, bordering on black, but beautiful nonetheless. She was pale, paler than them but her face was pink at the moment. She stood at 5'7, which Dean thought was a little too tall for him, but not a lot nonetheless. She was dressed for the weather of course as it was in Seattle, hair half up, a button-up shirt with some skinny jeans and knee-high boots.

"There's something wrong about you," Cass said out loud, staring intently at her.

"What?" Izzy said affronted.

"Cass!" Dean and Sam shouted together.

"There's something very off about you. You're not human, not completely, that is, but yet, there's no demonic presence either. I can't place you at the moment, but there is something..off," Cass continued, ignoring the brothers.

"Cass, that's enough," Sam said.

"Yeah, dude, you're being rude," Dean told him.

"You're not wrong," Izzy answered him.

"What?" Sam and Dean said.

"What are you?" Cass asked.

"I'm human, not normal but human, now you on the other hand, not normal people that's for sure," Izzy stared. She leaned against the counter and waited.

"I'm an angel of the lord," Cass answered before the Winchesters could say anything.

"Really Cass? You just spitting it out loud that you work for the fucking big guy?" Dean said.

"An angel really? That's a new one. Hermione's going to get a kick out of this," Izzy smirked. "And you two men in plaid?"

"Hunters," Sam answers reluctantly.

"What's that?" Izzy asked curiously.

"It's what it sounds like sweetheart," Dean said. "Except we hunt the other minority. The ones that scare people and goes boo in the night."

"Oh," Izzy said.

"Now what are you?" Cass asked.

"A witch," Izzy said and before she could even blink, there were two guns drawn on her. "Bloody hell what's the matter with you people?!"

"A fucking witch Sammy! Really? Rowena wasn't fucking bad enough, we have her now too?" Dean shouted.

"Slow down you two! Who the bloody hell is Rowena and why're you pointing your guns at me?" Izzy shouted at them.

"You're a witch. And so is she. From a Grand Coven apparently," Sam answered her.

"What in the name of Merlin is the Grand Coven? " Izzy asked.

"You're little witches council," Dean answered.

"We don't have a council you blithering idiot. We have a Ministry," Izzy told them. "Now point those guns away from me."

"Or what?" Dean said. "Sammy, the hex bags?"

"On it," Sam said as he pulled out a little red velvet pouch and placed it next to him.

"Now you even be able to do anything," Dean smiled.

"Are you going to say anything Angel of the Lord?" Izzy asked exasperated. "Cause apparently you can tell something's still off."

"She doesn't seem like a witch," Cass answered, tilting his head. "Whatever it is, seems to be running in her blood."

"What is?" Sam asked.

"Magic," Cass and Izzy said together.

"I am a witch. But not like those wannabe wiccans you guys have in the States. I was born with magic coursing through my veins; a magical core to be precise. There's generations of witches and wizards in my family who're the same," Izzy said pulling her wand from her pocket. "This is how I channel my magic. A wand."

"Seriously. You think we're dumb enough to fall for that shit?" Dean spouted.

"Bloody hell," Izzy rubbed her forehead. "Engorgio!" And the globe next to her grew four times its size and fell down. "Reparo." And repaired itself then. "Believe me now?"

Sam and Dean both stared at her in disbelief while Cass looked fascinated.

"Millenniums on this planet and I have never encountered anything like you," Cass stated.

"That's because we're good at keeping a low profile," Izzy told them. "Also, we, my kind, can erase multiple of memories of you lot to not remember if you do see it."

"So there's a chance of our memories being erased?" Dean asked incredulously.

"Well, I could, but if I manage to get rid of the mark, I'd have to erase even further down your memory and that could cause permanent damage. So, no, I won't erase your memory, but that doesn't mean I won't alter them if needed," Izzy told them.

"Are you saying the you can remove the mark?" Dean asked.

"It's a curse. Curses are reversible, but that's not always the case, so please don't get your hopes up," Izzy told them.

"Whatever you can do for my brother, we'll appreciate it," Sam told her sincerely as he put his gun away.

"I would appreciate your brother pointing his gun away from me," Izzy told Sam, pointing at Dean with a tilt of her head.

"Right. Dean?" Sam asked.

He gave a pointed look and Dean sighed as he put his gun away.

"Happy?" he said sarcastically.

"You have no idea how powerful I am do you?" Izzy asked him.

"A bullet will certainly make you powerless then, won't it?" Dean smirked.

"Please, you won't be able to reach the gun, let alone your bullet," Izzy smiled as she twirled her wand around her fingers.

"That's the source of your magic isn't it? The stick?"

"A wand, and it's a channel, really, not a source. A way to control the magic that's in me. A magical core, which, if prompted, can destroy this whole shop in less than five seconds. This channels that energy, and controls it. Helps me control whatever I do," Izzy told them.

"So, without the, the - um - wand - you can't control the magic?" Sam asked.

"I can control it, until I'm feeling too emotional or my feelings are heightened to an extent, then no I can't. That's with or without a wand. But we learn how to control all of that at Hogwarts."

"Hogwarts?" Cass, Dean and Sam said at the same time.

"It's a school for witches and wizards, and no, you can't destroy it because you'd have to find it, which you can't because it's warded. Has been for for centuries," Izzy sighed. "Are we going to ask for a whole lesson of the history of magic? Because that wasn't really my best subject at Hogwarts, and I really rather not get into it. I rather us be going to London so we can research on the mark."

"London?" Sam asked. "Why London?"

"Because that's where my friends are at, and one of them is fantastic at knowing ancient ruins and curses, so she can help. And everything we would need is over there. More extensive books on runes, which that mark is," Izzy explained to them as she grabbed her bag and her coat. "Is that alright with you?" She was locking up her store now, putting up the closed sign and texting Amy to take a vacation for the next couple of weeks.

"Alright, so I'll look up the next flight to London and we can be on our way," Sam answered for them all.

"Ah jeez," Dean said unhappily.

"I shall meet you there then," Cass told them.

"No, you travel with us Cass," Dean told him. "Human way and all, by a freakin' plane."

"We're not traveling by plane. That will take too long, plus you wouldn't know where to go, and no offense or anything," Izzy said looking at them and then at Cass, "I really don't feel like being flight buddies with an angel. Not big fans of you anyways." She sent him a disdain look.

"What did angels do to you huh? Not teach you how to fly? Made water hurtful?" Dean joked.

"First, really bad humor at witches expense. You Americans need to get better humor. And second, neither of those. They just took someone away from me, after everything I had been through, I deserved a little happiness, but they took it away," she said resentfully as she put her coat, scarf and beanie on, "so no, not a fan."

"Cedric Diggory?" Cass asked.

"Eight years now, gone. Thanks to you. But no, no planes. We're using a portkey, since there's too many of us, and since none of you know where to go, and I can't tell you, it's the only way and it's quick," Izzy smiled bitterly.

"Why can't you tell us where we're going?" Dean asked suspiciously.

"Because that place is not meant for Muggles - non magical beings - or angels to be allowed. It's hidden and I'm not going to explain that, Now, I have unauthorized magic to do," Izzy said picking up the now repaired snow globe.

"Unauthorized magic?" Dean said. "I need a fucking drink."

"Can we get some supplies while you work to get a port-whatever?" Sam asked.

"Sure, but be quick, this won't take long."

Sam and Dean exited the building, leaving Cass with Izzy inside and walked towards the Impala.

"I don't know about this Sam, this - this isn't normal. We don't know anything about her or her kind and we don't know how to kill them and now we're just gonna let her take us all to London in god knows where?!" Dean ranted as they opened the trunk and started putting supplies in a bag.

"Dean, look, I get it, but this is our only option right now, and right now, I'm willing to do anything and go anywhere to get rid of that thing on your arm," Sam said angrily. "So please, for once, stop fighting me on this."

"We don't even know if we can trust her Sammy," Dean said tiredly. "I want this thing off as much as you do, but what if we can't?"

"We'll figure it out Dean, just like we always do, but for now, all we can do is trust her."

Dean sighed and nodded.

"Besides, it's not like she's given us a reason not to," Sam defended her.

"You're just saying that cause you've got the hots for her," Dean chuckled. "Can you ever be into a normal chick?"

"Hey, she's normal," Sam defended his choice. "Just, she's different."

"Boy, you've got it bad Sammy," Dean low-whistled.

"Let's just go," Sam rolled his eyes and closed the trunk.

"I'll see you, soon baby," Dean said to his car and they went back to building.

As they entered, they didn't noticed Izzy smiling and showing a fascinated Cass some magic, and they both didn't notice the brothers entering.

"Levicorpus!" Izzy said and Cass was suddenly hanging by his ankle and Dean had dropped the bag and was pointing a gun at her.

Izzy, who heard the thud of the bag and turned and pointed her wand at Dean.

"What did I say about the gun?" Izzy said irately.

"Well that was before you decided to do that to Cass," Dean told her.

"Both of you, put your weapons down," Sam said, getting in the middle, staring at Dean and then Izzy, pleading.

She sighed, and looked in his eyes, and put her wand away. The hazel green eyes, went straight through her.

"Dean?" Sam said pointedly.

Dean, slowly but deliberately, put the gun away, still glaring at Izzy.

"You gonna put him down now?" Dean pointed at Cass.

"I was going to, before you decided to pull your gun at me, again, which I really don't appreciate," Izzy stoically said. She waved her wand silently and Cass landed on his feet. "He wasn't hurt you know. And if you'd like to know, your friend wanted me to try something on him. I'm not a bad person," she said it with a hurt and annoyed voice and walked towards the back of the shop, her bag slung on her shoulder and wand in one hand and the globe, which was now glowing in the other. "If we want to leave now, you better follow me."

Sam sighed and gave Dean a disappointed look and followed Izzy towards the back.

"She is helping us Dean, she didn't have to, but she is," Cass said before following Sam's lead.

Dean sighed and walked towards the back, joining his brother and the other two. There seemed to be a giant opening of space all the way in the back and Izzy was crouching on the ground, putting the globe down.

"You guys ready?" she asked coolly.

Sam gave Dean an annoyed look and answered for them all, "yeah."

"It's going to be cold when we get there, so you better be covered, and beware not to pull your guns out like you did with me. My friends and family aren't as easy-going as me, so I wouldn't," Izzy explained to them as she pointed her wand at the snow globe, "Portus," and the globe glowed brightly and dimmed.

"Woah," Dean said.

"Now touch it, all of you, now," Izzy said urgently, her own finger on it.

"What?" Sam asked.

"Touch it!" Izzy shouted and the three men all bent down and put their finger on, and it happened.

They felt as though a hook just behind their navel had been suddenly jerked irresistibly forward. Izzy's feet left the ground; she could feel Sam and Cass on either side of her, their shoulders banging into her; they were all speeding forward in a howl of wind and swirling color; her forefinger was stuck to the globe as though it was pulling her magnetically onward and then —

Her feet hit into the ground and she looked; Sam staggered into Dean and he fell on top of him; the Portkey hit the ground near Cass's head with a heavy thud as he laid sprawled on the ground.

DISCLAIMER: Supernatural and Harry Potter doesn't belong to me, obviously, except Izzy and some of the story line. THANKS.
