Over the coming weeks Harry fell into a routine of classes, schoolwork and Quidditch training three times a week. If he was honest with himself, though his classes continued to be interesting and in some cases even enjoyable, Harry was really living for the time he spent on the Quidditch pitch, going one on one against Wood and his Pelipper with Fletchinder at his side. It was nearly all Harry could think about, the next practice, but that all changed just a couple of weeks into October when Harry and Ron joined Hagrid on one of his trips into the forest.

Hagrid, the keeper of the keys and grounds of Hogwarts, had a very important job, Harry had quickly discovered. While he was in charge of the care of the Lapras that took the first years across the lake for the first time, as well as the Zebstricka who apparently pulled the carriages for the rest of the students, he was also tasked with the well-being of the many different Pokémon that inhabited the forest, a job that required a lot of hard work and patience, as well as skill and some powerful Pokémon at his side.

Hagrid had all that and today he had invited Harry and Ron along as he went searching for a Patrat that had fallen seriously ill. So, armed with their Pokémon and Hagrid's huge bag filled with medical supplies, the trio headed off into the forest.

"Now we'll want ter stay quiet," Hagrid told them in a slightly hushed voice. "Nothin' in here wants ter hurt yeh but if they think yeh're a threat they'll defend 'emselves." He continued forward, Fang and Aragog walking along beside him with Harry and Ron, accompanied by Charmander and Growlithe, following behind.

"First years aren't usually allowed around this area," Hagrid told them, pointing to a wooden sign post with a red circle painted on. "You won't be of the right strength ter deal with any of these Pokémon 'til third year, but as long as you stay with me, an' Fang an' Aragog o' course, there won't be nothin' ter worry about."

Truthfully Harry and Ron weren't worried. Perhaps they should have been, considering they were venturing into an area where the Pokémon would be stronger than their own, but it was hard to with Hagrid so close by, not to mention that it was a bright, sunny day and the trees were thinly spread, allowing the natural light to bathe the ground in a golden glow. In reality it was quite beautiful.

Suddenly a bush rustled ahead of them and, despite their previous thoughts, Harry and Ron stiffened. There was a pause, then the bush rustled again, and then finally the creature inside stepped into the light.

"Well, look what we 'ave 'ere," Hagrid said, a note of awe in his voice as he bent down onto his knees to look at the little Pokémon. "Have a look guys, this is a real treat. We don't normally see these type o' Pokémon 'round 'ere." Harry and Ron inched closer, still slightly wary though feeling a bit stupid about it considering how cute the Pokémon that had appeared looked. "This is a Deino."

"A Deino," Ron repeated as he and Harry peered round Hagrid. "I think I've heard of them before."

"I'm bettin' yeh're right," Hagrid told him with a nod of approval. "Deino here is a Dragon type Pokémon."

"A Dragon type," Harry breathed, inching forward to get a closer look. Hagrid, however, held up a hand.

"That's close enough, Harry," he said softly. "Deino here is a lil' nervous, we don't want ter scare 'im." Hagrid held out one of his massive hands and placed it on the ground before him. The Deino sniffed curiously, glancing up at Hagrid's face, before it slowly stepped forward, taking a sniff of Hagrid's hand, before licking it.

"I remember now," Ron said in a whisper as Deino contented itself with licking Hagrid's hand clean. "Charlie mentioned he was working with one in Romania." Ron's second oldest brother, Charlie, worked at a dragon reserve. Ron frowned. "I thought it would be bigger," he said, a touch of disappointment in his voice.

Hagrid chuckled. "Oh, they get bigger," he assured Ron. "This is the un-evolved form. One day this Deino will evolve into a Zweilous, and then it'll evolve again into a Hydreigon." Hagrid let out a sigh. "Beautiful creature, Hydreigon," he told them. "I raised one once."

Harry frowned. "I thought you said you'd never had a Dragon type before, Hagrid," he said, confused.

"Oh no, not really," Hagrid said sadly. "I was just raisin' it fer Dumbledore, see. He's got a big job now, up at the castle. I go visit 'im when I can. God, 'e must get so lonely." Hagrid grew teary eyed at the prospect while Harry and Ron shared a look over his back, each thinking the same thing.

There's a Hydreigon in Hogwarts.

They didn't say anything though as Hagrid seemed to get control of himself. "Hey there Deino," he said softly, causing the Pokémon to abandon its assault on his hand. "We're lookin' for a sick Patrat, you don't know where we can find 'im."

Deino looked up at him for a second before nodding its head fervently, jumping up and down and gesturing with its head deeper into the forest.

"Over there?" Hagrid asked hopefully. Deino nodded. "That's great. Lead the way, Deino." Deino happily jumped forward, seemingly completely at ease with them now as it had no hesitancy exposing its back to them.

"Hagrid, is Deino taking us there?" Ron asked incredulously.

"Yep," Hagrid said, a proud look on his face as he followed Deino. "One o' the first things I learned doing this job is that yeh can always count on Pokémon ter help yeh out." He smiled at their amazed looks. "It's true. I'm well known 'round here now, I've had the job so long, sometimes Pokémon come up ter me hut ter ask fer my help. And o' course, I always help with whatever I can."

And for the rest of the day, as Deino led them to the ailing Patrat and Hagrid tenderly shared his medicine, Harry and Ron looked at their giant friend with a new found respect. However, there was one thought in the back of their minds that neither boy could shake, and that was the mystery of Hagrid's Hydreigon.


They managed a week before they gave in, which all things considered Harry was quite impressed with, as the curiosity burned him even more than his desire to get back out on the Quidditch pitch. He had to know where Hagrid's Hydreigon was, and if Ron's attitude was anything to go by, he had to too.

They managed all the way until next Friday before Ron broke their unspoken agreement of silence.

"You know, I reckon it's what's on the third floor," Ron said out of the blue at lunch time. Harry blinked, he was still trying to recover from the morning's potions class.

"What are you talking about?" he asked, though as he did he realised the answer himself.

"Hagrid's Hydreigon," Ron said in an excited whisper. "Listen, I've been thinking and there's no way a Pokémon that big can be roaming around the castle without someone noticing. No, I reckon it's being kept somewhere and the only place in the castle where we can't go is the third floor corridor."

Harry glanced around carefully. He wasn't sure if anyone cared about this conversation but if what he suspected was true it would be good not to be overheard. "So what do you suppose we do?" he asked in a whisper.

Ron grinned. "We've got to see it, of course," he replied, his voice rising slightly in his excitement. "Think about it," he continued as Harry looked unsure. "How often do you think we'll get the chance to see an actual Hydreigon? You heard Hagrid when he said Deino was rare, how rare do you think Hydreigon will be?"

Harry glanced around again. "What are you suggesting?" he asked, though he had a good idea. Ron's eyes gleamed.

"We go to the forbidden corridor tonight," he said excitedly. "We see that Hydreigon. I mean, it's Hagrid's so it's not like it'll hurt us. A Hydreigon, Harry. A real, live, fully evolved Dragon type. I bet Malfoy hasn't seen one. Heck, I bet even Snape hasn't seen one. Come on, Harry."

Harry looked around for a third time. He was feeling really paranoid.

"Alright," he whispered quietly, Ron giving a victorious grin at his agreement. "But we'll need to be careful. We don't want anyone catching us out of bed, especially sneaking about around there."

Ron nodded and so the plan was set. Harry felt nervous at the idea of sneaking out late and venturing to the one place Professor Dumbledore had specifically said not to go to. However he couldn't deny he felt a little excitement too and as the day went on and he and Ron patiently waited for Neville, Dean and Seamus to fall asleep his anticipation grew.

Eventually their dorm mates were all asleep, as were their Pokémon, and Harry and Ron crept silently out the door and down the spiralling staircase to the common room below.

"What are you doing here?"

Harry inwardly cursed. He had assumed, given the late hour, that the common room would be deserted by now. But he had failed to count on Hermione Granger, who was now staring at them with a mixture of curiosity and suspicion.

"None of your business," Ron snapped back before Harry had the chance to come up with something. Now she was really suspicious.

"You're sneaking out," she said loudly and Harry couldn't help but flinch as the noise carried up to the dorms. Fortunately it seemed like no one had heard. "Why?"

"We told you, it's none of your business," Ron told her angrily, striding past and opening the door to the common room. "Come on Harry." With a feeling of dread Harry followed.

"Hold on just one moment," Hermione hissed after them, following them out and standing there in the corridor, arms crossed across her chest. "It's against the rules to sneak about at this time, don't you realise how much trouble you could be in if you're caught."

Harry could and Hermione could tell that he had from the moment he'd first considered sneaking out. She huffed.

"Unbelievable," she said, throwing her hands in the air while turning back to the door to the common room. "Good luck to the both of you." She pushed the handle. The door remained closed. Hermione paled.

"Looks like the door's locked," Harry said weakly, paling as well. "Must be one of those automatic ones." Of course that meant that he and Ron would have trouble getting back in when they were done. Their plan was starting to look worse and worse with each passing second.

"Well, we've got things to do," Ron said briskly, seemingly taking heart from Hermione's misfortune. "Hermione, good luck to you." And he started off at a brisk pace, Harry following hurriedly behind. However, a third set of footsteps followed.

"I'm coming with you," Hermione said as they both turned to look at her.

"No you're not," Ron said immediately. "You didn't even want to come. Why would we let you tag along now."

Hermione bristled. "You do realise we are locked out until someone lets us back in," she challenged Ron. "And I don't want to sit around out there all night waiting for Filch to catch me, no I do not. We're all much better off sticking together, now that we're all in the same boat. Safety in numbers."

Ron turned to Harry in exasperation.

"Makes sense," Harry admitted. "Besides, it'll be easier to avoid Filch with three sets of eyes and ears on the lookout."

Mr Filch, the Hogwarts caretaker, was not someone you wanted to bump into in the early hours of the morning. A hunched, foul and overall disgusting man, Argus Filch was the scourge of all Hogwarts troublemakers, whether it be the Weasley Twins or some poor sod running in the corridor he'd catch them and put them in detention. Aided in his trench war against the students, Argus Filch was always followed by his Glameow, a decrepit looking thing that constantly looked half starved. Glameow, or Mrs Norris as Filch called her, was perhaps hated even more than Filch himself for she seemed to always appear at the worst possible moment, with Filch two steps behind her.

Harry had already gotten on Filch's bad side twice in the month he'd been at Hogwarts so far. The first time was when he tracked mud through the Entrance Hall after Quidditch practice. The second time he'd accidentally stood on Mrs Norris' tail. It went without saying that anything that could help keep Filch and his blasted Glameow away was worth whatever price you had to pay.

"Fine," Ron admitted, though not happily. It seemed that Hermione's appearance had put a damper on his enthusiasm. "But if you get us caught I swear I'll chop you up and feed you to Growlithe." Based on her expression Hermione wasn't sure whether he was being serious or not.

"Lets go," Harry told them and together the three of them, silent as mice, started to descend the many floors of Hogwarts, all the while staying alert.

The journey seemed a lot longer in the dead of night, and the castle itself looked so very different, so much so that the trio had to reorientate themselves more than once to make sure they were on the right track. Finally they reached the third floor and the door to the old Pokémon Stats corridor was standing before them.

"This is where you wanted to come," Hermione hissed in a horrified whisper. "This is the forbidden corridor. Dumbledore expressly warned us that it was too dangerous."

"Yeah yeah," Ron said, more carelessly than Harry would have liked. It seemed that in the face of Hermione's caution Ron had decide to go the other way. "Are you ready, Harry?" The excitement was back.

Harry nodded. He reached out to grasp the handle, and pulled.

The door remained shut.

"It's locked," Hermione told them, giving the boys an exasperated look. "Did you really expect Dumbledore would just allow anyone to waltz in here? Someone could have got lost and found this by mistake. Seriously, what a waste of time."

"Would you shut up?" Ron growled angrily. "It's not like I didn't come with a plan." From within his pocket Ron retrieved a couple of small silver instruments. "Lock picking kit," he told Harry with a grin. "Fred and George taught me. There's no lock that can keep us Weasley boys out."

Hermione humphed. "So what your telling me is that you could have got us back into the common room all along," she said, hands on hips.

"Yeah," Ron said, grinning and looking very pleased with himself.

"Then why didn't you?" she demanded.

"Didn't want to," Ron shot back easily. He seemed to be having a lot of fun. "Stand back," he told the pair of them, kneeling down by the lock and going to work.

"Why are we here?" Hermione asked Harry quietly, trying not to grab Ron's attention.

"You'll see once we get through this door," Harry assured her. He could feel his anticipation growing as Ron methodically twisted and turned his lock picking tools until eventually there was a loud grating sound and Ron stood back with a triumphant grin.

"Here we go," he whispered excitedly, reaching out to grasp the door handle. As an afterthought Harry placed a hand on Charmander's Pokéball, the thought only just occurring to him that this might not be safe. And then the door was open.

The first thing Harry was aware of were the heads. Three of them, each dark blue with red flaring around it. The centre head was larger and protruded up higher than the other two, which seemed almost like hands with the way they were held on two black arms. The Pokémon was floating before them, suspended in the air by the flapping of six black, tattered looking wings.

Then it screeched.

"Lock the door!" Harry yelled, flinging himself forward to slam the heavy door shut in the abominations face. Ron fiddled with his tools, his hands shaking so badly that he could barely keep hold of them.

A massive hit rocked the door, momentarily opening it and allowing the young Gryffindor's another peek of a monstrous head before Harry pushed it closed again.

"Ron, concentrate!" Harry yelled, trying to give himself as much of a brace against the door as he could. "Hermione, help me!" His cry was accompanied by another hit that caused him to stagger, but not fall. "Come on!"

Hermione looked terrified. Her face was white, her limbs shaking. She was completely frozen.

"Got it!" Ron shouted in success, to which the monster smashed against the door again. It shook, but clearly Ron had managed to push the lock back into place.

"Good job, Ron," Harry said, panting. Just a few seconds ago his blood had been pounding through his veins, now he was just about ready to pass out.

"Do you think the door will hold?" Ron asked nervously. Another bang sounded from the other side. Hydreigon clearly had not given up on them yet.

"Don't know," Harry answered. "But I know I want to be as far away from that thing as possible if it does get through."

Ron nodded. "Agreed," he said. "Come on." He started to make his way down the corridor.

"Wait," Harry called back. Ron stopped and turned but Harry's attention was on Hermione. She had not moved, not an inch, from the moment Hydreigon had attacked. "Hermione," Harry said, trying to keep his voice gentle but urgent at the same time. "Hermione, come on."

Ron was having none of it. "Come on," he said roughly, grabbing her by the arm and physically dragging her down the corridor. "We can sort you out later but right now we need to get away from that door."

The journey back to the Gryffindor common room was, incredibly, teacher free. Harry was sure that the racket Hydreigon was making would have woken the whole castle but, now that he thought about it, the sound of Hydreigon bashing against the door had faded some time ago.

Hermione still hadn't spoken, though she was at least carrying her own weight now. It seemed that her body had gone onto autopilot and that the essence of Hermione, her personality, had been left behind.

It wasn't until they were back in the Gryffindor Common Room that anyone spoke.

"Wow," Ron said. Harry thought that pretty much summed it up. "Well, I'm not listening to anything Hagrid tells me anymore. Beautiful creature, my arse."

"Why?" came a low tremor from behind them. "Why did you go looking for that?" It seemed that Hermione had found her voice again.

Harry and Ron shared a glance. "We didn't know it would be like that," Harry said, by way of explaining. "We just heard there was a Hydreigon at Hogwarts, we didn't know it would be a monster."

Hermione just shook her head in disbelief. "Did you at least read the Pokédex entry for Hydreigon?" she asked, as though already knowing the answer. Harry and Ron shared another look.

"Eh, no, not as such," Harry admitted, pulling out his Pokédex and quickly scanning for the Pokémon he wanted.

"Hydreigon, the Brutal Pokémon," the Pokédex announced ominously. "This brutal Pokémon travels the skies on its six wings. Anything that moves seems like a foe to it, triggering its attack."

There was a pause.

"Ah," Harry said simply. That made a lot of sense.

"Yeah," Ron agreed but to Harry's disbelief a smile was growing on his face. It grew and grew until Ron was laughing, hysterically.

"What do you think is so funny?" Hermione said crossly.

Ron just shook his head. "This is brilliant," he chortled. "Did you see that Pokémon. Brutal. And it's tail and legs looked like they'd been cut off or something. That's the scariest monster ever and we saw it, up close."

Harry had to smile at that. True, they probably should have done their research rather than simply winging it, but it had been an amazing experience.

"Honestly, what's wrong with you?" Hermione said loudly. She clearly didn't agree. "You still haven't told me why you decided to go looking for that thing in the first place."

Harry looked at Ron and raised an eyebrow. Ron shrugged. It seemed right that she know, considering they'd almost got her killed, the shrug said. And so Harry told her.

He told her about Hagrid mentioning that there was a Hydreigon in Hogwarts and how they had guessed it was being kept in the forbidden third floor corridor and how they'd been hoping to see a really cool Dragon type, which Hagrid had called beautiful.

"Beauty's in the eye of the beholder," Hermione said weakly as Harry finished. "But why? Why is there a Hydreigon in Hogwarts? Surely the safest place for a Pokémon like that is deep within the forest. Except…" Hermione tailed off, staring into the distance. Harry and Ron looked at her.

"Except what?" Ron asked impatiently, hating the suspense.

Hermione didn't answer immediately, instead she allowed her mouth to open slightly and she let out a breath. "Except that there was a trap door," she said eventually, her voice soft and far away. "Beneath Hydreigon, it was like it was guarding something."

Harry and Ron shared a look.

"About that," Harry started, gaining Hermione's full attention. And so he told her about the mysterious package Hagrid had rescued from Gringotts and all of a sudden the three of them were in the conspiracy together.


A/N: Hi everybody. I hope you are all enjoying the story so far and thank you so much to anyone who has read this. I just wanted to briefly talk about something that was brought up in a review, which I will split into three parts.

1) Firstly, thank you so much for taking the time to review and for supporting this project. Of course the reason I post here rather than simply keep these stories for myself is in the hope that other people might enjoy them, so I'm grateful for all the support.

2) Second, while I really appreciate reviews I would advise that if you have a question or something you want me to clarify that you get an account. This way I'll be able to PM a response to you directly and you won't have to wait for the next chapter to have your questions answered. Creating an account is very easy and it's free (something I should definitely know as I very recently created my own account) and I would highly recommend it for even the most casual of fan-fiction viewers.

3) Lastly, and answering the question that sparked this whole comment, I would like to clear up how Quidditch works in my story. The reviewer in question asked if the trainers do anything or do they just watch the Pokémon play and the answer is they mostly just let them play. The best way to think about it is to compare it with professional sports teams with the Pokémon as the players and the trainers as the coaches. The trainers can create the tactics and call plays but at the end of the day it is up to the Pokémon to perform.

I hope this clears up any confusion and I look forward to seeing you in the next chapter.
