Okay, I want to take the time to thank each of my reviewers individually for the wonderful, enthusiastic reviews you guys have written! Without you guys it wouldn't be as fun to keep writing. So thank you Evil Kasumi, the.old.amsterdams,strawberryalchemist, Natycat, Sei-sama, ChainofDreams, mihawklover and BlueFlowerAlways. :) Well, hope this doesn't come out too late, school has started and it's been rather hard to work on this. This story will always be a priority though 'cause it's so much fun. Anyway, if you haven't already, go ahead and start reading the story.

…

This feast is excellent, Usopp thought; I'll bet it has food from every country on this world. He noticed, with laughter, that Ron seemed to have developed an aversion to many of the new types of food resting on their plates. There was something called "Bouillabaisse" that tasted really neat and which was apparently from somewhere called "France" and also some rather pale dessert that he didn't know the name of, and that no one else seemed willing to eat.

Then the Headmaster stood up to address the gathering. "This year, as you all know, Hogwarts is hosting the Triwizard Tournament in which both the schools, Beauxbatons and Durmstrang, have been kind enough to join us in competing. Now, myself, along with Mr. Bagman, Mr. Crouch, Professor Karkaroff and Madame Maxine will be participating on a panel that will judge the champions' progress as they compete in a set number of challenges. The first judge, however, the judge who decides who may and may not enter is completely impartial." He cleared his throat, "Mr. Filch, would you be so kind as to bring out our judge?"

An older man with a woefully ragged coat clambered up to the front of The Great Hall. In his arms he held what looked like a beautiful treasure chest, rubies, diamonds and all. Usopp couldn't help but clutch at his bag, which he hid inside his cloak, in eagerness hard to reconcile with his usual character. Surely if I could bring back a treasure as valuable as that chest my crewmates would welcome me back with open arms, a parade even. But there his thoughts stopped being quite so animated. Of course, I'd have to steal it in front of hundreds of students first… And then bring it back to a completely different world.

The man, Filch,awful name, stooped down to hoist the large chest from the floor to a podium apparently set up for it. Then the Headmaster, smiling at the anticipatory hush of the crowd, slowly lifted the lid. Inside was what could have easily been the most ordinary, roughly hewn wooden chalice ever made, except for one fact. Over the topmost rim of the cup Usopp could see that the object was filled with an ethereal blue-white flame. This made him pause.

Something about that chalice is awfully familiar. I've seen it before, somewhere different though… Usopp struggled to recollect, but before he could grasp a hold of the wisps of memory stirring through him he was called back by the Headmaster's voice.

"This is the Goblet of Fire. Anyone wishing to participate in the tournament must write their name and the name of their school legibly on a piece of parchment and drop it into the Goblet. You have twenty-four hours in which to do this. Tomorrow night the Goblet will reveal to us three names. That means one champion from each school will be competing." He paused, "To prevent harm to any of our bold, but younger students, there will be an age limit. Nobody under the age of seventeen will be allowed to compete."

There was a general chorus of, "What? Seventeen!" from the entire student population, minus Hermione. The two red-haired twins, Fred and George, or George and Fred, tried to stand up on the table to lead a protest, but were stopped by a couple of rather irritated Gryffindor students. The twins glared at the offenders.

"We're almost-"

"Seventeen. We should be allowed-"

"In!"

Ron began grumbling about "stupid age barriers" and "bloody rules." "We could probably find a way past it you know…"

The Headmaster sighed, "There will be no arguing on the age limit, it's already been decided. Well, on that note I bid you all good night."

With that, Dumbledore tipped his hat at the students and effectively dismissed them all. Everyone began filing out the doors, and Usopp followed as Harry, Ron and Hermione made their way to the back of the hall. The Durmstrang students were about to walk through but stopped when the man, Professor Karkaroff, blocked their way. He was openly staring at Harry. Usopp looked curiously around and saw that several of the foreign students were pointing at Harry's forehead or whispering his name. It all stopped, though, when Professor Mad-Eye Moody came up behind the students and fixed the man Karkaroff with an eerie, rather unnerving stare. Dislike seemed to pour off both men in waves. The Durmstrang students quickly left, some looking rather green. Wow, when Hermione said Harry's parents were famous she wasn't lying. For students from another country to know who Harry is, is amazing. It's strange though, they kept pointing at his forehead as if it was somehow important. It's somewhat rude to be pointing at someone's scar, but I think that's what they were doing. Sad if that little scar is the kind of thing people find impressive around here.

Usopp snapped himself out of his thoughts just as Hermione, Ron and Harry were making a beeline for the Gryffindor Common Room. Usopp yawned and was just about to split off toward his own room when Hermione grabbed his arm.

She fixed her gaze on him, "Usopp, we have some things we want to ask you about. Could you come to the Common Room with us?"

Usopp, though slightly on edge by the way all three students were staring at him, consented.

Once settled on one of the many chairs lining the Common Room, Hermione started the conversation. "Usopp, we know you don't come from this world. Harry overheard the teachers talking and they seemed to think that your Grand Line is in a completely different dimension." Usopp heard Harry mutter, "Well, some of them," before Hermione continued, a frown crossing her face. "The point is, the teachers also said that they knew someone who had once gone to your world, and that they brought back some strange tales…"

Hermione seemed uncertain if she should continue, but Usopp hardly cared anymore.Someone has gotten to the Grand Line from here! That means I can go home. He silently cheered. Then Harry picked up where Hermione had left off and the smile that had been forming on Usopp's face fell off as if it had been treading a dangerous cliff. "They said that most people in your world are either pirates or Marines. Hermione figures that you aren't just a civilian. So…what are you?"

Usopp could see that both Ron and Harry's faces were showing varying degrees of excitement, while Hermione's was creased in slight worry. Usopp was more inclined to lean toward Hermione's way of thinking. The students at Hogwarts might believe the fact of Usopp being a pirate rather neat, personally he saw himself as a rather dashing figure so he wouldn't blame them, but the teachers would certainly not. Adults were almost always more practical minded and would see Usopp for what he was, a rogue. A good-looking rogue, of course, but he couldn't really see Professor McGonagall or Professor Moody caring about that. How do I get out of this? "I'm just a lowly painter, really," he gulped, "Nothing piratey or Mariney about me. If I was back home I could show you one of my many master-"

Ron cut him off. "Oh, come on Usopp. Hermione saw how you looked at Durmstrang's ship."

Hermione added, "Don't tell me your going to pass up the chance to brag of how much treasure you've gained or how many pirates you've caught."

Hermione's voice had been softly mocking, but Usopp hardly liked the glint in her eyes. He steeled himself. "If I tell you this, you've got to promise not to repeat it to a soul. Okay?"

Harry looked unhappy, but Hermione continued regardless, "I can only promise that if your secret is something that won't hurt any of us, or anyone at Hogwarts."

"Fair enough." Usopp sighed, "Where to begin… Well, first of all, you guessed right. I am a pirate."

Ron cheered and pumped a fist in the air while Harry looked at him incredulously. Apparently, when Usopp actually admitted the pirate part out loud it didn't sound quite as believable as Harry had thought it would. Hermione just stared at him. She'd probably already figured it out and was just confirming her guess. There was a moment more of silence and then she spoke. "Why?"

Usopp paused at that. Why? For hundreds of reasons. "I guess because my father was one…" he trailed off, and then caught himself, "Because Gol D. Roger's treasure is out there still waiting to be found. Because the Grand Line is the greatest challenge a sailor can ever take…" Because I found a crew, nakama, that I thought could help make my dream possible... Usopp frowned, then grinned to cover up what had become a far too serious moment, "And because back home people call me the greatest marksman to ever sail the Grand Line! They call me Captain Usopp, sailor of the most dangerous seas and tamer of the fiercest monsters. Only those too dense to realize who I am don't run away screaming at the sight of me."

He finished off his monologue by examining his nails as if the details he had just mentioned were far too trivial for him to care about. Their reactions were not exactly as he'd anticipated.

"Oh, mate, you're a riot!" Came Ron's muffled voice. He was apparently trying very hard not to collapse to the floor laughing. Harry and Hermione had more decency, but Harry was looking decidedly too blue in the face, from what Usopp could see around the hand trying to stop an eruption of laughter, for his liking.

Hermione was the first to cease giggling, though she only seemed to achieve silence through severe self-control. "Well Usopp," she laughed for a second, but then brought it back under control, "what I would like to know about is something that one of the teacher's briefly mentioned. They said that, so far as it appeared, there was no magic in your world. Your reactions when you first came here seem to confirm it, but I was wondering how you deal with the Sea Dragons and large lizards in your world if you don't have magic to keep them at bay. They sound dangerous."

Usopp was about to answer flippantly that no one he knew needed magic to ward off the creatures of the Grand Line, but he seemed to have caught onto Hermione's train of thought and found it more intriguing than he thought it would. How indeed? No one in this world seems to have anywhere near as much physical strength as Zoro or Sanji. Devil Fruits don't seem to exist here either. Why are our worlds so different? He shrugged and answered honestly, "In the sense you're talking about I really have no idea. All I know is that our worlds are a little different. Back where I come from there are a lot of people who can take on a Sea King, err... Sea Dragon, single handed." He puffed himself up proudly, "I'm certain I could do it if someone gave me the chance. I need only-"

He found himself interrupted, "Are you sure there is nothing even remotely like magic where you come from? I've read theories on separate dimensions and, well, granted, they are only theories, but most of them conclude that even if dimensions are separate they must have several important underlying things in common with each other to make it possible to cross over. Magic is very important in this world so…"

"Well… There are the things that we call Devil Fruits," Usopp noticed everyone appeared to be intrigued with the name. "In our world certain types of fruits grow in special places and they're more unusual than the normal fruit we eat. There are probably more varieties of Devil Fruits than anyone can count but it's rare to actually see one. It's not as rare to meet someone who has eaten one though, 'cause dangerous fruits grow in dangerous places and the people who eat the fruit like to show off."

"Why? What do they show off?"

"Well, the Devil Fruits give people powers. I guess it is kind of like magic if you think about it that way. Some fruits can turn people to rubber, others let them detach and reattach their body parts, others can let them turn into smoke or fire or even control another person's emotions. The only thing they all have in common is that once you've eaten one you lose the ability to swim."

Ron couldn't seem to understand the gravity in Usopp's voice, "Well, who goes swimming all the time anyway? Sounds like a fair tradeoff to me."

Hermione barely concealed the rolling of her eyes as Usopp continued, "Most of our world is made up of ocean. Usually the only lands you can find are small or large islands."

With a small grin Hermione spoke, "So, to obtain one power you give up another. Since most people choose to be either a Marine or a pirate I imagine it's somewhat of a risk to eat the Devil Fruit."

Usopp nodded. There was silence for another minute before Ron, once again, broke in. "So, Usopp. Have you ever killed anyone?"
