Noble1998 here, sorry for taking ages to update but I was busy studying for assessments, gaming and watching more of Fairy Tail. Oh and it will not be a Harry/Erza pairing, more of a platonic love due to her resembling Lily in a lot of ways, I'm also wondering if Harry should magically adopt her or not. Anyways enjoy this chapter and don't forget to review. Harry Potter belongs to J.K Rowlings and Fairy Tail belongs to Hiro Mashima.

Chapter 1:

X784:

Lucy POV:

Team Natsu had just returned from their unauthorized S-rank mission to Galuna island.

'I am so bored and the team isn't taking any missions soon, at least my rent has been paid, hopefully they aren't invading my house again' By 'they' she meant Team Natsu who had a habit of using her house for different reasons and had absolutely no regard for her privacy.

She was just walking along the streets when something caught her attention. It was a shop that had rainbow neon lights at the front of the shop, which spelled out 'Hogwarts store of magical delights'. 'That store is obviously a magic store, but what sort of name is Hogwarts?' But since she had nothing else to do she decided to go in and take a look.

Walking in through the front door, she was immediately gobsmacked by the fact that it was actually much larger inside than it had seemed outside. Looking around she could see kids happily running around and laughing while playing with toys ranging from mountable flying broomsticks to chessboards that had pieces moving by themselves.

At another section she saw some people looking at dark, glittery dust with a sign above saying 'Peruvian Instant Darkness Powder', all around the store she could see suits of armors that resembled Knights moving around and helping people. 'Bu-, but they're just suits, how can they actually move and talk!' she thought in shock.

Then to her immense surprise she saw Erza of all people looking around the sweets section, specifically at strawberry cakes. She went over to talk with her since she felt a little lost in the big and lively store.

"Hey Erza, I didn't expect to see you here."

"Hmm? Oh Lucy, yes well the cakes here are absolutely marvelous and I also come here sometimes for custom made armor and weapons" Erza replied.

"Oh, well could you help me out a bit since I'm a bit lost here"

"Oh sure, just let me get 30 of these cakes"

"THIRTY?!" she screamed out in shock with her head growing bigger anime style.

"Of course, you can never have too much cake after all, now let me put them in the basket." Erza then looked at a strange symbol engraved onto a nearby pad attached to the shelves and spoke to it while touching it with her index finger. "I would like to order 20 medium sized strawberry cheesecakes and 10 large ones as well please"

Then to Lucy's shock 30 different sized boxes came flying to them then stacked themselves up and then promptly shrank of all things, which Erza then picked up as it was a small bundle now and placed in a nearby shopping basket.

She was snapped out of her shock when Erza spoke to her.

"So Lucy, what do you want?"

"What do you mean?"

"Well, this store pretty much sells everything you can think of, you see it has one of the largest collections of books in Fiore, unique types of foods, manuals on magic and spells, even Celestial spirit keys to flying broomsticks and even weapons. You name it and Hogwarts has got it"

"Wow, but this sort of stuff has to be really expensive right?"

"Yeah but Harry sells everything for a low price, even lower to Fairy Tail members"

"Why would he give discounts to Fairy Tail members though?"

"He's actually a member himself, but he hasn't been active like Mirajane for a few years now"

"Oh, I never knew that"

"Mhhmmm, mmmmm…."

"Eh? Erza?" Lucy turned around only to see Erza already having finished a cake. (Cue sweatdrop from Lucy) "wow, she eats quick doesn't she?" she muttered under her breath.

"Anyways Lucy, do you want to meet him now?"

"Oh yeah sure"

Lucy followed Erza up a spiral staircase passing several more floors filled with merchandise and customers till she stopped in front of a door that had a sign on it saying 'Harry the Wizard Whiz'.

Erza knocked on it.

"Come in." called out a voice from the other side.

When they stepped in Lucy saw a raven colored, messy haired young man with the brightest green eyes she'd ever seen. 'Did his eyes just twinkle?' she thought to herself incredulously.

"Hi Harry-ni, how was your day?" Erza asked.

'W-WAIT! SHE HAS AN OLDER BROTHER?! Well now that I look closely they could pass off as siblings…'

"Oh it was terrible Erza-chan, so much paperwork" the young man complained with a groan. "Oh, and who's this?" he asked while gesturing to Lucy.

"Oh this is Lucy Heartfilla, she's the newest Guild member" Erza replied.

"Uumm, hello Harry-san, pleased to meet you" Lucy said a bit nervously.

"Oh, you're the new girl that Natsu picked up, the one who cos-plays right?"

Lucy facefaulted but then suddenly jumped up.

"I DO NOT COSPLAY!" she yelled out embarrassed and with her face bright red with her ears blowing out steam.

Harry's POV:

The new girl interested Harry since she was a spirit summoner but unlike most summoners he meets, she treats them as her friends instead of tools and had a lot of magic power potential and would grow to be a strong mage in the future, but her current combat skills were lacking. He could tell all this with a look at her aura.

Noble1998: Next paragraph will be about what Aura-sight is, if you don't wanna read about that and move onto story the just skip.

Codex-Aura-Sight

Aura-sight is a skill that Harry has developed during his time here in Earthland. It was attained only by the strongest wizards and witches from his world such as Dumbledore or Voldermort. Aura-sight allows one to see and perceive magic itself and allows him to examine and manipulate anything related to magic to an extent. For example, he could see rune barriers and because he can see the magic used, depending on how good the runes are as well as the power the user had used, Harry could modify the runes to what he wants or even break through them. He can see a person's magic core which gives them their aura and see what they're like, for example, he sees Natsu's aura as a small dragon with potent fire surrounding it with the Fairy Tail symbol next to it. This showed Harry that Natsu uses anti-dragon magic based around flames but is still hasn't achieved the full power of Dragon Slayer as his Dragon is small but he is still powerful evident by his potent flames, his aura also shows the Fairy Tail symbol because it shows that's his reason to fight, to protect his family and friends as well as his guild.

You can imagine how useful this sort of thing is as it shows Harry a person's true nature and the nature of an magic. This is how Dumbledore could see and find Harry under his invisibility cloak or how Voldermort could easily smash through wards.

End of Manual- Aura Sight

Noble1998: Back to Story

He also only added that he thought Lucy was a cosplayer because it was funny and he wanted to see her reaction.

"Please take a seat" and he waited for them to sit down on the chairs in front of the table.

"Allow me to fully introduce myself, Harry Potter at your service." he said with a charming grin.

Lucy POV:
Lucy's heart stopped for a moment, this was HARRY POTTER, one of the strongest known mages who was even offered a position as a wizard saint but had declined it stating that he didn't need fame. She didn't know that he was actually part of Fairy Tail and ran a shop or more like market.

But Still, this man was said to be able to conjure things out of nowhere, animate anything from statues to paintings, control a lot of elements and one of the widest repertoire of spells the world has ever known. He has such as wide range of magic it was ridiculous. Runes? Has a never before seen version of it. Weapons? He could make swords and shields out of nowhere and a large number of them. Alchemy? One of the most well known potion makers and had a reputation for making potions that actually worked. Healing? A thought to be lost art, then he comes and shows the world that with a flick of his wand he can heal even the most grievous of injuries. To be frank, this man was one of the most if not the powerful mage ever seen before and she was glad that a man like him was on the light side and not a dark mage.

"Ah, ah, pleased to meet you." She said in a meek tone.
I mean come on, you don't just go and piss of a well-known SS-Rank mage by annoying them.

He frowned before saying "Hey, come on Lucy, we're all Fairy Tail mages, we're nakama now so you don't have to be scared of me."

"Ah, Okay then" she replied back in a more confident tone.

He smiled before turning to Erza.

"So what can I do for you and Lucy today little sis?" he asked Erza.

Lucy was in shock. 'She really is his sister then…but why aren't there last names the same?'

"Well Lucy here is a Celestial Spirit summoner so I was wondering for you had something in stock for her?" Erza asked him.

Harry's brow was scrunched up in concentration as he was thinking. Meanwhile Lucy was very hopeful that he had something even if wasn't Gold keys.

"Yes I do have something for her… FLIPSY!" he suddenly called out. Then with a crack a little… creature for she knew no words to describe it appeared startling only her while both Harry and Erza were just unsurprised.

"Master Harry called for Flispy" it asked to Harry while bowing.

"Oh yes Flispy, could you go down to storeroom 14 and bring out the Power-pump, also please bring some tea for me and my guests." Harry addressed to her.

"Of course Master Harry, Flispy will do so right away." And with another crack disappeared.

"W-what was that?" Lucy asked in shocked while pointing at where the House-elf had been before disappearing.

"Oh that was just Flipsy, she's a house-elf and serves me and quite splendidly as well."

"Uh, okay…" Lucy answered back in a hesitant tone.

Crack! Flispy appeared again holding in one hand a tray with tea and sugar cubes while in the other she held a clear see-through box. Flipsy set down the tray onto Harry's desk while handing the cube like box to Harry.

"If that be all then Flispy shall retire back to her post"

"Yes thank you Flipsy and the tea does look appetizing, please continue with your duties." He said with a nod.

Flispy then bowed and said "Of course Master Harry" and with a crack disappeared again.

Harry then set a cup of tea in front of each of them and took a sip from his own. Lucy tentatively took a sip and her eyes widened in shock from how good it was, she looked up from her cup and saw Harry smiling smugly.

"Now you're probably wondering what this is right?" while gesturing at the cube in his hand. She nodded at him and he smiled before explaining. "This is the power-pump, I created this little beauty myself. What it does is that it keeps siphoning off your magic levels and because of this your magic starts to try and refill it self constantly and like a muscle the more you exercise it the more it gets stronger, well same thing with your magic. I thought this would be good for you since a Summoner should always have high magic levels in order to call spirits in quick succession or even simultaneous summonings, so go ahead take it." He explained while holding it out to her.

She reached forward and grabbed it and started to take a closer look at it. "So how do I activate it?" she asked.

"Oh just push some of your mana in." he replied. (Not sure if in Fairy Tail world it's etarano, magic or mana so if someone could tell me it'd real nice)

She did so and pushed a small portion of her magic in. The cube glowed green then dulled down and was starting to just emit green light.

"See the cube is glowing green meaning that it's at the beginner stage and is siphoning a little of your power at a time, if you keep this active at all times then because of the constant drain, your magic reserves will boost up, after that you keep turning up the levels"

"Ah, thank you, but I don't see how this is very useful to me." She said to him.

"You're a celestial summoner are you not? This means that bigger magic reserves means that your spirits not only last longer, you could even multi-summon and if you have more to spare, you can actually imbue the spirits with your magic, thereby granting them more strength." He explained patiently to her.

"Ah I see, thanks for this Harry-san" she said gratefully with a contemplative expression on her face.

"We'll be going now Harry-nii, take care." Erza then said to Harry while pulling Lucy with her to the exit.

Lucy went with Erza while thinking about all the things she could do if she had more magic power.

"See you girls next time" Harry called out to them while smiling

Lucy smiled; Harry was a really good guy in her opinion

Harry POV:
As soon as the door to my office closed, my smile dropped and my body started to shake and convulse.

"Not again…" I muttered to myself.

FLASH

He was in his memories again, watching from the sidelines the battle where many of his cherished friends died.

The scenery was in hogsmeade, what was left of it anyways… he could see many buildings burning and rotting corpses on the streets. There were death eaters everywhere, killing, torturing, looting and other horrible things with the civilians running away screaming, the aurors fighting valiantly but failing and finally the Order members. There they were, Luna and Neville, the 2 had gotten together before the war had started and he had been happy for them, but in this memory, he saw the fighting back to back and easily cutting down scores of death eaters, but there were too many of them.

"RUN HARRY! WE"LL HOLD THEM OFF!" shouted Neville.

He saw his younger self being pulled back by Hadgrid and was shouting "NO! NEVILLE, LUNA, DON'T YOU DARE DO THIS!" while having tears in his eyes from knowing the truth.

Neville smiled grimly, "Don't you worry about us Harry, we're not going down that easily and besides, we need you for Voldermort, can't have you dying here."

"Yes Harry, besides, we're not ever truly leaving you, even if we're not there physically we'll still be in your heart" came next from Luna.

"WHAT! NO! YOU'RE MY FRIENDS, I CAN'T LET YOU DIE LIKE THIS" came the outburst from his younger self.

But before his past self could do anything Hagrid picked him up and disapparated from the battlefield.

FLASH
It was dark and only a destroyed landscape and many corpses remained. He saw his past self, choke on the smell of rotting corpses but still looking for something. His younger self found what he was looking for and ran to the side of a very pale and wounded Neville.

"Ne-neville, why the hell did you do this mate? Why did you have to stay behind, we could have spent more time together as friends and everything, but you're dying here instead…" came the choked out whisper from memory Harry.

The near death Neville just smiled sadly at Harry.

"Harry mate, even if I die, and don't say anything because we both know I will, I'm not truly gone, like Dumbledore said, I'm just going on the next great adventure." Neville quietly said while looking out at the stars. "It's funny you know, I was always thought I'd end up as a herbalists or running a apothecary. Who would of thought that I become a bad-ass wizard and got lucky enough to have great friends, huh?"

Harry was having tears in his eyes. "Yeah mate, you are pretty badass and I'm lucky to have fought together with you."
Neville smiled, not an ordinary smile but a true one. "I guess I'll be joining Luna, Gran and my parents now…."

"Yeah Nev, and when you get to the other side, please tell Remus, Sirius and my parents that I love them, can you also give Sirius a punch in the gut for dying that day the ministry?"
Neville chuckled. "Sure thing Harry" Sigh. "The stars are beautiful, cough, tonight aren't, cough, they?" and with that Neville drew his last breath.

"Yeah…they sure are mate, …" past Harry sobbed while looking up at the sky.

FLASH
Harry drew in a huge breath and was covered in a lot of sweat. Hedwig was next to him trilling a beautiful melody that helped sooth his mind and heart.

"Do not worry Harry, we're here for you" she said in his mind.

His staff in wand mode also pulsed in a comforting way.

"Yeah brat, so don't go all gloomy on us now." Harry looked up and smiled. Standing in front of him was a confident man who wore many battle scars, dressed in red and gold with the Gryffindor symbol and a sword on his hip. He had messy light brown hair and warm chocolate brown eyes with a steely measure in them

"Hello Godric." Harry greeted.

"Don't worry child, I'm sure that they're proud of you and I'm also equally sure that they'd hex you for being so depressing" the spirit of the Sword of Gryffindor said.

Harry chuckled and was glad to have such good and loyal companions. "Yeah, I guess."
He picked up a white King piece from the chess set that Ron had given him back when they were kids.

He closed his eyes and relaxes against his chair while twirling the chess piece.

'But I do wonder, how much longer can I fend him off?'

Unknown POV

A figure dressed in a black cloak and wearing a skull mask grinned menacingly.

He was tossing and catching a black chess King piece between his hands.

"Oh don't worry little lion, I'll be watching and as soon as you screw up … well I'll crush your pathetic being!" it said in a dark and double tone (Think Ichigo's inner hollow voice from bleach) while suddenly crushing the chess piece in his hand into dust.

"Oh I can't wait till the day we battle again … the Lion against the snake… but which one will win I wonder? The brave and bold or the sly and cunning… I'll be seeing you real soon again … King."

END

So guys, what do you think and if you want to learn more about Godric or the unknown entity, well you'll have to read and find out. Noble1998 says goodbye and see you next time, also there is preview below.

Next time:

There were shades everywhere, they were endless and relentless and kept coming no matter what the Fairy Tail mages did… until suddenly … a white/silver spirit of a phoenix flew and decimated them. All eyes on the battlefield turned towards the caster and there was a sight to behold. A man with dark messy hair dressed in red and gold robes with a majestic looking sword in one hand and a powerful, pulsing staff in the other. His eyes were a burning blaze that were lurking with power, his mouth began to move.

"To you, Phantom Lord who hurt innocents and my nakama, prepare yourself for suffering" his voiced echoed thunderously.

He raised his staff and slashed it down towards the imposing mobile guild, a large griffin made of unreal, awesome, powerful fire burst out and headed towards it.

There was a bright flash of light from the impact.
