Author's Note: Hello! Here I am with another HP crossover fic. I just can't seem to get enough of them. For those of you that also have read my SherlockxHP crossover I SWEAR I'M NOT ABANDONING IT. I know there already a lot of Winchesters go to Hogwarts fics but I still think there should be more. When I write, I tend to use a lot of the headcanons I have developed by reading other people's stories so if there is an idea I have stolen from you, please know that it is not intentional and please message me so that I can credit you accordingly. Also, I try to be as accurate as possible when it comes to facts and characterizations, but sometimes I will slip up. Please let me know of any mistakes or inconsistencies that I have made. I am only on season 7 of SPN and most of the rest of my knowledge is from spoilers so I will make mistakes because of that. The HP area should be better but I haven't read the books in a while so I'm not sure. Just so you know. Also do the Winchesters still call him Chuck or do they call him God now? I don't know how they react to him anymore so I'm sticking with Chuck for now. That may change.

Albus Percival Wulfric Brian Dumbledore, Order of Merlin (first class), Headmaster of Hogwarts School of Witchcraft and Wizardry, Supreme Mugwump of the International Confederation of Wizards, Chief Warlock of the Wizengamot, and one of the most powerful wizards in the world was utterly, and completely, at a loss. Ever since the Triwizard Tournament and the revival of the Dark Lord, the situation had been steadily getting worse. Firstly, the Ministry refused to believe that the Dark Lord could be back. The media had been attacking him, and now Harry, too. Dumbledore could only imagine what the boy would have to endure once the school year starts again. His hearing was coming up in a few days and the incident has definitely not helped his relations with the ministry. Secondly, if he did not find a new DADA professor soon, the Ministry would appoint one, no doubt to keep a closer eye on him and Harry. Dumbledore sighed. Lastly, there were the attacks. Aurors had gone to investigate reports of witches and wizards being attacked, and identifying their attackers, only to find that they had been missing for weeks and were found, dead, miles away from anywhere they had any business to be. Despite thorough investigation, there were no patterns other than the fact that all of the wizards seemed to have disappeared within a week of the Dark Lord's return, and traces of yellow powder around the crime scenes. The whole affair was mysterious and extremely confusing. In all his long life, Dumbledore had never heard of such a thing and, thus, did not know how to stop it. The old wizard was not a particularly religious man, however, the situation was dire and it could do no harm. He did something he had not done in years. He prayed to God. Albus Dumbledore did not expect much from this action. In fact, he did not expect any reaction at all. He hoped – Oh how he hoped - with all his heart, but knew better to expect a miracle. What he really did not expect, however, was, exactly 30 seconds after finishing his prayer, for a man to suddenly materialize in the middle of his heavily warded office, which is located in an even more heavily warded, unplottable castle.

Chuck had been proofreading a new chapter, when he heard the desperate plea for guidance. He wondered who it was. Albus Dumbledore. One of his creations that he was fairly proud of. Very long lasting. The wizarding world had actually been a spur of the moment decision and one he had come to regret numerous times. He had been particularly bored one day and the idea just popped into his head. In hindsight, giving magic to creatures who were not designed to handle it was not a great idea. At first, it was actually quite disturbing, like seeing Windows 10 on a CRT monitor. Just somehow wrong. After a few adjustments and fixes, however, it was at least manageable. Having them channel power through staffs and, eventually, wands rather than it just exploding everywhere had really made a difference. Right now though, the wizarding population was in turmoil. The Dark Lord was gaining power and the idiotic government was ignoring that and, instead, going after the one he had chosen as saviour. Chuck wondered why that always seemed to happen. His chosen ones always seemed to have rotten luck. Normally, the creator would have left them alone and let the situation resolve itself, however, Riddle somehow managed to enlist the help of some dark forces. Chuck knew that nobody in this time would be able to save the wizards, so he looked forward. Twenty years forward, in fact, to the year 2015 and saw two of his favourite creations who would be able to aid the wizards.

Sam Winchester had seen a lot. He had been infected with demon blood at the age of six months, had his girlfriend burn to death on the ceiling, literally been to heaven and hell, had seen his brother die over a hundred times, and had even been possessed by Satan himself. He had been raised into the hunting business, encountered creatures from any horror story, folk tale, or myth you could think of. Sam had seen a lot, but walking into the kitchen on a Tuesday morning and seeing God pouring himself some coffee is enough to make anyone pause. Chuck turned around and smiled at Sam.

"'Morning," he greeted. "Coffee?" Sam stared. After a bit he blinked and cleared his throat.

"Uh, no thanks. I'm good," he replied, shifting uncomfortably. There was moment of awkward silence where both parties stood and stared, waiting for something to happen. Once Chuck realized Sam wasn't going to continue, he sighed.

"Why don't you go get your brother," he said. "I don't want to explain twice."

Dean was not happy to be woken up, but soon they were all sitting at the table in the war room nursing mugs of coffee.

"Okay, so what's the deal?"

"I have a job for you two," Chuck said. "Just hear me out, but first, there's some stuff you need to know." He then proceeded to tell them about the wizarding world. Sam was surprised to see his brother listen patiently to the whole explanation. Usually, he would have been expressing how unbelievable the story was. Natural born witches? Schools for witchcraft? Sam supposed that the fact that it was God himself telling them this directly that gave credibility to the tale. Chuck then moved on to explaining the situation and why he needed their help. When he finished, Dean put his empty mug down on the table and took a deep breath. Sam was still trying to process what had been said.

"So let me get this straight," he said. "You want to send us to 1995 to help a bunch of natural born magic users fight against this Riddle guy, who hates non-magic people and has somehow managed to get demons and other supernatural beings on his side."

"Yes."

"Do we have a choice?" Dean asked, looking up at Chuck.

"I won't force you," he said with a soft smile, "but I really suggest you do."

Dean thought about it.

"Alright." Sam stared at his brother, shocked.

"Seriously? Just like that?"

"You don't think we should?"

"No, I just – I thought you'd fight it more. Let someone else save the world for a change." Dean just sighed.

"Who else is there, Sammy? Saving people, hunting things. It's our job. As much as I don't want to deal with somebody else's war, we can't just sit back and let it happen. From what we've heard, these wizards don't stand a chance. They're all relying on a kid to win the war for them. All because of some prophecy! Sam, you of all people should understand what that's like. Everyone telling you how your life is going to play out because you're some kind of chosen one. Telling you that you can't change a thing. That it'll happen no matter what because it's destiny. Think of the pressure that must put on the poor kid. We can't leave that alone. Not unless we want him to end up like us."

Looking at Dean, Sam understood why his brother had agreed so easily. Dean's protective instinct seemed to extend to complete strangers sometimes. The fact that this Potter kid's situation reflected some of Sam's own, only increased it. Sam took a deep breath. As soon as Chuck began explaining, Sam knew they wouldn't be able to let this one go. The amount of innocents in danger was enough to convince them.

"You're absolutely right," he said to his brother before turning to the other person in the room. "We accept. What do we have to do?" Chuck smiled.

"I have already spoken to the Albus Dumbledore, the man who prayed for my help. He is the headmaster of Hogwarts and the leader of an organization called the Order of the Phoenix. He told me that two things were most important. Educating the wizards about supernatural monsters, and protecting Harry Potter. The easiest way to do that would be having someone teach at Hogwarts."

"So we'll be teachers?" Sam asked.

"Not quite. When you get sent back, you will physically look like yourselves from 1995."

"What!?" Dean exclaimed. Sam did some quick mental math.

"I'll be 12!" Ignoring their protests, Chuck continued.

"You wouldn't have the magical knowledge required anyway. Which is why you will be attending Hogwarts as students." This seemed to shock the hunters into silence. There was a pause before Dean let out an incredulous laugh.

"And how will we do that? In case you haven't noticed, we aren't exactly magical."

"And that's where you're wrong. Sort of. There is an odd thing that occasionally happens where a non-magical child is born into a full blooded wizard family. Those children are called squibs. They have a certain amount of magic; enough to see magical creatures and not be affected by anti-muggle wards, but not enough to cast spells. If you track both your Campbell and Winchester lineage far enough back, you will find that many of your ancestors were unknowingly squibs, resulting in you both having an abnormally high percentage of dormant magical blood. I can draw out that power and amplify it so you will be able to access and channel it just any natural born witch or wizard." Both brothers took a minute to take in this new information.

"Okay," Sam said. "But how are we supposed to teach these wizards if we're students? Maybe some adults would listen if we could convince them we know what we're talking about, but a bunch of kids sure as hell won't take lessons from their fellow students."

"And that part is what I didn't want to tell you until you had taken the job on your own. I'm sure Robert Singer would be able to handle a teaching position."

"Bobby's dead."

"Not in 1995." The brothers froze. "I can give his 1995 self all his memories up until his death." At that moment, Sam and Dean's thoughts were racing, but one thought – the same thought – stayed at the forefront of their minds. We can see Bobby again.

Once the boys had calmed themselves down, they began to think more about the detail of their mission.

"So what's our story?" Dean asked. "Are we just gonna show up there and they're expected to believe we know what we're doing? They'll have questions that the truth won't satisfy." Chuck nodded.

"I've told Dumbledore everything and he believed it, but that is probably because he heard it from me."

"Yeah," agreed Dean. "Hearing it from God himself usually gives stories a bit more credibility."

"If anyone questions you," Chuck continued. "Tell them about you being Men of Letters legacies. They held quite a lot of power in the wizarding government before they disappeared. That should give you at least a small bit of political sway and immunity."

They ironed out a few small details and, finally, there was one question left.

"What's the plan?"

"When I send you back, you need to go to Bobby's. I'll explain the situation to him and he should be waiting by the time you get there. Albus Dumbledore will contact you and lead you from there."

"Okay, so, for you to send us back, what do we have to do?"

"Just close your eyes."

Dean woke up feeling like he got hit by a truck. He tried to remember what happened. He was talking to God with Sam... Sam. He opened his eyes and, once his vision had stopped swimming, sat up. Dean froze as he spotted his little brother lying on the floor a few feet away from him. And when he said little brother he meant little brother. Sam groaned and rolled over, giving Dean an even better look at his sibling's 12 year old form. While normally, Dean would leave Sam to wake up and get his bearings on his own, gone was the intimidating, giant, hunter Sam and in it's place was scrawny, twelve-year-old, not-even-had-his-growth-spurt Sammy. Seeing his little brother once again small and vulnerable lying there on the floor made Dean's overprotective big brother instincts kick into high gear.

"Sammy!" He called as he knelt beside his sibling.

"De...?" Sam muttered as his eyes fluttered open. After some confused blinking, they widened. "Holy shit," he whispered, staring at Dean's face, taking in every inch of it. Only then did Dean realize that he must look different, too.

"Guess we really did go back in time, huh Sammy?" Said brother only frowned.

"It's Sam." Dean just laughed.

"Dude, that didn't work on me when you were a 6'4" giant. It sure as hell ain't gonna work as a scrawny ass tween. You sound like one of those singing chipmunks. Bitchface is still the same as ever, though."

"Jerk."

"Bitch," Dean said as he helped his brother up only for him to stumble almost immediately. Luckily, Dean was there to steady him. "You alright?"

"Yeah," Sam nodded. "I guess I'm just too used to being twice this size."

After making sure his brother wasn't going to fall over, Dean left Sam to try and figure out his limbs on his own and headed to his room to see if he had any of Kevin's left over clothes, because there was no way Sam was going to be able to wear any of his clothes now. Dean opened the door to his room and stopped. Because this wasn't his room. Not yet. He wouldn't find any of Kevin's clothes because Kevin never stayed there. None of them had stayed there. The Bunker hadn't been used in 37 years. So many things hadn't happened yet. So many people hadn't died yet. Kevin hadn't even been born. The apocalypse never happened and it never would if they – No. Stop. Dean shook his head. He'd been through this before on numerous occasions. Meeting his parents (both times), being death for a day, unsinking the Titanic (which Castiel eventually told them about at some point). Trying to change the fate never ends well. Realizing that there were no clothes to be found (fitting or otherwise), Dean headed back to the library to see how Sam was doing. Dean donned an amused grin as he watched his, now tiny, brother struggling with a pile of books a third of his height.

"Need some help there, Sammy?"

"Shut up," Sam replied, face hidden by heavy tomes. "It's just gonna take some getting used to, that's all." Almost immediately after the words left his mouth, Sam stumbled, almost dropping his pile of books. Luckily, he managed to right himself, but Dean's grin slipped into something closer to concern and went to help his brother out. Dean lifted half the books from Sam's hands and placed them on the table.

"What are these anyway?" He asked. Sam took a second to catch his breath before replying.

"Chuck mentioned that the Men of Letters used to have contact with the Wizarding World. I figured they'd have some books about it and, since we agreed to help these guys out, we should know what we're going to be working with."

"Okay. Grab what you need and let's go. We need to get to Bobby's."

"How, Dean? The impala's not here yet, remember?"

"...SON OF A BITCH!"

Author's Note: Sooo? How did I do? Sorry if some of it seemed long winded. There was a lot of information to lay out and it was hard to keep it flowing. I know I am completely ignoring the fact that John Winchester would probably freak out if his kids suddenly disappeared (they must have because I don't want two versions of them in the same time period) but I couldn't think of a good way to deal with that. Maybe next chapter I'll address it. Maybe. I usually don't like bringing dead characters back to life but I didn't want to have the Winchesters dealing with Umbridge the whole time. At some point they will but not yet. I could have chosen John Winchester instead but I figure it would make more sense for Bobby to secretly be a wizard. Anyway, please review. It helps motivate me and sometimes sparks ideas that help get past certain problems that I was stuck on. I'm sure I have made mistakes so let me know. Also, all of this makes sense in my head but it may not translate that way. Let me know if things need clarification. Thank you for reading, please review and I hope you continue to follow this story.
