AN: A little bit of info before the story starts, I would just like to say that this is my first ever fanfiction, so please excuse any mistakes :). As for the pairings in this, it will be mainly Nalu, with Gajevy, and Gruvia on the sides, but they will not come into play until a bit later into the story. For HP pairings, it will be all the canon pairings, but again, those will not come into play until later. All that aside, let's get started! :)

Prologue: ANOTHER world?

An old man, with an unusually long beard, sat in a study, studying a set of parchment. An unusual bird sat in a cage in the corner of the room, preening his feathers. The man furrowed his brow, grabbing a particular letter from the stack of papers.

"Where did this come from?" He muttered to himself. He carefully opened it, a glittering blue gem and a small sheet of paper falling out. The man studied the gem for a moment, then turned his attention to the letter. His eyes quickly swept over the letter, his eyes widening with each sentence he read.

"T-This is exactly what we need!" He gasped, then grabbed the gem, pointed a wand at it, and started muttering incantations, the gem slowly getting brighter. Finally, there was a flash of blue light and the man disappeared without a trace, the letter falling to the ground.

"WHAT DID YOU CALL ME ICE PRINCESS?" Natsu roared, slamming heads with Gray.

"I called you exactly what you were, Flame Brain!" Gray yelled back, glaring at Natsu. "An idiot who's only trait is blowing up and destroying towns!" Natsu snarled, and pulled out a flaming fist. "You wanna go? Fire Dragon's Iron-" "ICE MAKE: LA-" Just as they were about to clash, two fists slammed down onto their heads, successfully knocking both of them to the floor.

"CAN YOU TWO BEHAVE FOR ONCE?" Erza yelled, then went back to her seat, a plate of a half finished strawberry cake in front of her. Natsu and Gray both groaned, and stood back up, going to their respective seats with a final glare.

Lucy laughed, sitting at a bar stool with Wendy and Cana, looking at the guys. "They never learn do they? Well, at-" Wendy and Cana never did find out what Lucy was going to say, because at that moment, a very large crash came outside the guild doors, the building itself shaking from the impact.

"W-What was that?" Wendy cried out. Suddenly, the door opened, as everyone started preparing for a fight, Lucy going for her keys and whip, Erza requipping into an armor, and Natsu lighting his hand on fire. As the dust from the shaking cleared, an old man with a long beard was spotted, his hand gripping a strange wooden stick.

"Hello there, Fairy Tail members. My name is Dumbledore, and I have come from another world to hire a group of people for a mission to guard Harry Potter. My world needs you!" the man, now identified as Dumbledore said pleadingly.

"ANOTHER WHAT?" every member cried out.

And thats a wrap! Now that Dumbledore is here and ready to hire some Fairies, let's see what happens next! Don't worry, the later chapters will be longer than this, since this is just a prologue to get things kicking. If you have any questions, feel free to leave a review, as I will be answering them in the next chapter. Again, this is my first fanfiction, so please excuse any OOC or grammar mistakes. See you next chapter!
