Summary: Usopp and the rest of the Strawhat crew land on an island full of secrets; secrets that may have something to do with a magic that doesn't even come from the Strawhat's world. Usopp's starting to learn that strength and power doesn't always come in the form of muscles or Devil's Fruit.

…

The familiarity of the sea spray hitting his face, something he normally enjoyed, did nothing to ease the humiliation he felt. Usopp covered his face with his hands and prayed to the pirate gods that he could just sink through the deck and disappear at the bottom of the Grand Line. He didn't. But as far as Nami seemed to be concerned his embarrassment was hilarious.

"You should have seen your face Usopp," she tried to cover her giggles with her hand, "the sea monster's right behind you!" She burst into laughter.

Usopp glared at her. Really, how was he supposed to know that she'd rigged a puppet to look like a monster? It had looked plenty real when it had jumped at him from over the side of the ship. He glanced at the thing and noticed how pathetic it looked. He could have made one of a far superior quality. This thought, incidentally, did not make him feel any better. He decided he'd point it out to Nami anyway.

"I can't believe you made it out of string and bed sheets. It looks sickly."

"Hey!" Sanji yelled, "I helped my precious Nami with her beautiful sea dragon. It might not compare to Nami's radiance but you…can't…insult…it!" Sanji punctuated each word with a kick aimed at Usopp's head.

Usopp dodged them, barely, and managed to escape to the upper deck when Nami distracted Sanji by speaking aloud her intention to sunbathe. Usopp heaved a sigh before he sat down by the railing of the Merry Go. He wouldn't normally have minded being the butt of one of Nami's pranks, after all, she pulled one nearly every day and Usopp wasn't her only target, it was that the joke had been based off of last night's incident. Did they mean to do it? He had no way of knowing. All he knew was that he'd been left out. Left out for perhaps the first time since he'd joined the Strawhat crew.

It had been late, and Usopp had thought that everyone was asleep. He himself had been as well until a creaking noise close to the hammocks startled him. He'd looked up and seen all the other guys entering the cabin as if they had just gone out somewhere. He'd noticed their clothes were torn and that Luffy had a bandage on his arm. They'd told him that they'd been fighting a sea dragon but that everything was okay; they'd handled it. They'd handled it without me. No one had even bothered to wake me up.

Usopp wasn't sure what to make of it. He'd have been scared of the monster yes, but he'd gone through worse before. Hadn't he proved himself? Before he could muck through the rest of the implications of it he heard Chopper'sshout of "Land Ho," and turned to see a rather small, quaint island coming up fast to the right of their ship. He jumped up, momentarily distracted from his thoughts, and joined everyone on deck to gaze at their destination.

…

Once they docked in the harbor Usopp got a clear view of the town. Houses made of brick, wood and some kind of strange stone dotted the landscape around the harbor, and the people who lived in the houses were all curiously opening their doors and windows to see who had just come into the bay. Everyone on board, except Luffy, tensed. There was no telling how the locals would react to a pirate ship calmly sitting at their dock. Then the tension seemed to dissipate from the air as the people began laughing and talking again. Some even went so far as to set out their wares and call plaintively out to the Strawhat's to buy their exotic merchandise. Usopp smiled, a town that welcomes pirates, that's a nice change.

Nami, patting down her orange hair as it threatened to become windswept, laid down the ground rules. "Okay, Luffy, no wandering off. Don't think I didn't notice last time. Zoro, no drinking. Absolutely none. Sanji, get us some more spices, were almost out. Usopp, you can sell some of the treasure we found." He made as if to protest and she glared at him, "You know we need more money…. All right, lets go. We can meet back here at noon."

"Might as well join the circus," Usopp muttered, "for all the consideration I get here…"

As they left the ship Usopp noticed Luffy standing back on the deck with a strange look on his face, though it vanished as soon as he saw a candy stand. According to Nami's orders Zoro reluctantly followed him. Usopp began walking in a different direction. He hadn't the faintest clue where to sell their treasure in the small town, so he randomly chose to move west and hoped there was a bank somewhere in the area.

Halfway down a side street someone in a hooded cloak blocked his path. Usopp stepped back, reached for his slingshot and prepared to scream as loud as he could, but he didn't get the chance. The man whipped out what looked like a long stick from a pocket in his robes and pointed it at him. Usopp heard him utter something that sounded like "Stupefy" before his vision faded and he fell.

…

Usopp awoke to the sound of birds chirping. He blinked; there hadn't been any birds when he'd blacked out. He got quietly to his feet, feeling a shade dizzy, and glanced around. The sight made him fall straight back on his butt. In front of him were hundreds of enormous trees. A forest. Why am I in a forest? The trees seemed to be stooped, leaves browning and trunks graying with age. A thick haze settled around the roots of them, giving the area an eerie feel. Usopp shuffled backward. He hoped that when he turned around he'd see civilization, some sign of people. The quiet notching of an arrow told otherwise. Usopp froze.

Then in front of him walked the strangest animal Usopp had seen in a while. It was a horse with the torso of a person situated where the horse's head and neck should be. It also had white-blond hair and startlingly blue eyes, and was aiming an arrow at his chest. Another one, this one darker in coloring, came in from the side and spoke.

"What are you, human, doing trespassing in our forest? This forest is forbidden for a reason."

Usopp shivered, the animal's voice was as kind as frost. Though he supposed he couldn't really call it an animal anymore. He figured asking "what are you" would probably be taken the wrong way so he settled for something he hoped was a little less rude. "Where am I? Am I still in the Grand Line?"

The creatures' looked at each other. The darker one murmured, "The visitor the star's predicted perhaps?"

The lighter one inclined its head in what Usopp supposed was acknowledgement and then stepped forward, gracefully trailing a hoof through the fog. "Where do you come from?"

Usopp readied his answer but before he could so much as speak a word a guttural growl emanated from the bushes behind the horse creatures. A large, shaggy head with a maw full of sharp, dripping teeth emerged. This new creature resembled a wolf, but seemed much bigger than Usopp was used to and he shuddered as he watched the enormous shadow of the beast, contrasted so harshly with the fog under its feet, move towards him. It watched him with dark eyes and Usopp knew he had to do something quickly before he died in this strange forest.

In an instant he had his slingshot out and aimed at the snout of the monster. He loaded it with a rock he had in his pouch, and fired without a second's hesitation. The monster yelped, growled softly, and, shooting a startled glance at Usopp, vanished the way it had come. The lighter horse creature, the only one that remained when the monster appeared, shot an admiring look at Usopp.

"Not many humans show so little fear in the face of a werewolf. Tell me, what is it you are doing here?"

Usopp shrugged, "Trying to find my way back to the Grand Line. Can you help me?"

The horse creature solemnly shook his head; "I cannot help you in that respect. I have never heard of the Grand Line. But I believe I know some people who could assist you. I'll lead you there."

Author's Note: This is my first story in either the Harry Potter or the One Piece fandom so please bear with me. I have an outline for this story so hopefully I'll make better progress than I did on my last one. Anyway, feel free to review if you like. Thanks for reading!
