AN: I do not own Harry Potter or Fairy Tail, I also wish to add that I did take several ideas from different writers who have inspired me.

(Tenrou Island-X784)

Harry grinned as he watched the boat stop a distance from the island "Seems like your guild is back Mavis" Mavis giggled "Yep, I wonder who had been chosen this year, who do you think will win?" Harry tilted his head "I want to put my money on Cana". Mavis chuckled "I figured you would say that, she has been here for the last five trails, maybe she will actually tell Gildarts this year" Harry chuckled "Here's hoping, plus she is really strong".

Mavis nodded and leaned against Harry, the person who had become her closest friend, she had told him all about her curse, her immortality, her body hidden under the guildhall and Zera's body hidden under the Tenrou tree, Harry had in turn, told her about his old dimension and his old life, he had introduced her to Dobby, Winky and Kreacher who were all astounded by her presence of kindness, she giggled remembering Dobby asking her if she was a fairy or an angel.

She scowled remembering what she had heard about Dumbledore, she wanted to Fairy Glitter the old meddling fool, she had also met Hela and Solaris, Harry's closest family bar the three house elves and the newly reborn Hedwig in her Phoenix form, Hela was quite bemused when Mavis had hugged her and thanked her for looking after Harry. Harry looked at her "And what are you giggling at? Little Fairy" Mavis grinned at the nickname "my first meeting with Hela, my Phoenix Knight".

Harry smiled fondly at that moment and grinned as he watched the groups of two enter the different caves, he stopped and stared at the pink haired one who declared that he would go down path E for Erza, Harry snorted before turning to Mavis who was giggling "Shall we watch path E?" Mavis nodded and Harry brought up the screen. Both laughed as Natsu's face faulted slightly when Gildarts was stood there instead of Erza, his grin came back at full force and he threw himself at Gildarts.

(Path E)

Natsu threw himself at Gildarts with a flaming fist "Fire Dragon's Iron Fist" Gildarts raised his hand to block the attack but was pushed back form the force of the attack, Happy just stared in awe, Natsu quickly twisted around and came down with a leg drop "Fire Dragon's Crushing Jaw" Gildarts raised his arm to block the attack, the ground splintered and cracked under the pressure, Natsu jumped backwards and inhaled "Fire Dragon's Roar" a giant torrent of fire shot towards Gildarts who grinned "Crash" the torrent turned into squares all the way to Natsu who gasped before disappearing.

Gildarts gasped in horror "Oh no, Natsu, damn it" Happy was openly crying "What did you do? You killed Natsu" a voice responded "Always be on guard Gildarts" they both looked up to see Natsu coming down in a pillar of flames "Fire Dragon's Sword Horn" Gildarts raised his arm again and the ground became a crater. Natsu quickly jumped out of it "Dragon Slayer Secret Art: Crimson Lotus, Exploding Flame Blade".

Natsu was instantly shrouded in flames and was shooting off like a javelin towards Gildarts who put his cloak in the way, there was a massive explosion, when it had faded, Natsu was stood several metres away from Gildarts whose cloak had massive burn holes in it, he was bruised "You have impressed me Natsu, you may pass". Natsu shook his head "No, I refuse, I will fight you properly, stop holding back" Gildarts sighed "If that is what you wish" he released his magical aura causing the island to shake.

Happy fell to his knees from the pressure before turning to Natsu expecting the same but was shock to see Natsu still on his feet, his eyes sharp and the magic not seeming to affect him at all, Gildarts was also surprised but hid it well. Natsu sighed but released his magic until it perfectly matched Gildarts' own, he grinned at Gildarts and rushed forwards, Gildarts did the same, the two clashed for several minutes before they both laid on the ground winded.

Gildarts looked at the young man next to him, he always knew that Natsu was hiding something but he didn't know what until now "You have old eyes, eyes that have seen the world, is there something you are not telling me Natsu?" Natsu sighed and looked up at the sky through the broken ceiling "After the trails, I'll tell you everything" Gildarts nodded "I'll hold you to that", Natsu sat up "Does this mean I lost?" Gildarts sat up "I already told you that you had passed, get out there and become an S-Class".

Natsu grinned "Will do old man, see you again soon" Natsu then grabbed Happy who was very confused before running out of the cave leaving a highly impressed and chuckling Gildarts "That kid is gonna go far". Natsu rushed out of the caves to see Gajeel and Levy sat down in front of Master Makarov, he went over and sat down looking bored, Happy just grinned and began to eat a fish as they waited.

(30 Minutes Later)

Makarov coughed getting all of their attention "now that you are all here, these are the results, Gray and Loke surpassed Mest and Wendy" Gray and Loke bumped fists "Cana and Lucy surpassed Freed and Bickslow" everyone stared at the two who grinned. "Levy and Gajeel found the pass of no aggression" Gajeel scowled and Levy grinned "Natsu and Happy surpassed Gildarts" everyone turned to Natsu with wide eyes, he just looked bored with the situation.

Makarov continued "Juvia and Lisanna lost to" he shivered "Her, the knight that doesn't know how to hold back" everyone shivered in both fear and pity "And Evergreen and Elfman faced off against Mirajane as they are not here" "WAIT" everyone turned to see a limping Elfman and Evergreen walk out of the cave. Makarov blinked "And Elman and Evergreen surpassed Mirajane, now the next challenge is to find the First Master's grave within the next 6 hours, good luck".

Natsu stood as the others ran off in random directions, Natsu felt a pull on his magic and a nostalgic grin appeared on his face as he walked back into the caves, Happy following, Makarov watched in shock 'how does he?' before quickly following. Natsu wandered through the caves until he came to the opening, he looked at the grave with the sword on it and grinned, he kneeled in front of it and poured some of his flames into the open flame in the grave.

He then looked down at the sword "Thank you for looking after it for me" he placed his hand on the sheath and smiled as he felt the rush of warm, familiar magic wash over him, a hand landed on his shoulder, he looked up to see Master Makarov looking at him with a mixture of shock, confusion and awe "How did you?" they both froze as they felt an extremely dark magic flare, Natsu growled "Later gramps, I need to go" Makarov nodded and Natsu rushed off with Happy, the sword in hand.

(With Elfman and Evergreen)

Both of the mages looked on in horror as the wave of black magic flew at them, suddenly something jumped over them with a sword in its hand, they instantly thought Erza until they saw the mop of pink hair 'Natsu?'. Natsu ignored the two behind him as he looked at the oncoming wave of death energy "Sword Magic: Sword Skill Number 372, Absolute Negation" he swung the sword at the wave and watched as the two magics cancelled each other out.

Natsu turned to the two mages and Happy "Go, I'll handle this guy" "Natsu?" Natsu glared "There is no time Elfman, that magic will kill you if it touches you, go" Elfman and Evergreen nodded and rushed off, Happy stared at Natsu who smiled "Don't worry buddy, I'll be back soon, go see Lisanna" Happy looked at the wizard in black before nodding "Good luck Natsu" and he flew off. Natsu turned around and stared at the wizard who smiled ta him with tears in his eyes "What are you doing here Zeref?".
