Chapter 1: History! Ash's Lesson in Pirates!

A picturesque day on the high sea. With various marine life enjoying mostly clear skies, the surf seemed to be a fun place. For a group on a dinosaur swimming, clear skies cleared the way to new adventure. The blue dinosaur had fins for legs, a rocky spike shell and a small horn on its forehead. On its back were three humans, a yellow mouse and a white spike ball wearing the red and blue shell as clothing. A raven-haired boy wore a red baseball cap and an open blue jacket over a black t-shirt while having the yellow mouse with a tail forged like a lightning bolt on his shoulder. A redhead girl had a tuff of hair sticking out the side as she held the egg. She wore a sleeveless yellow midriff and jean shorts. The last was a raven-haired young man in a turquoise t-shirt, shorts and a red headband. "You know, I wish I spent a few more days at Luana's resort," she sighed.

"Misty, you know Ash would rather finish the Orange League before he wants to rest up," the teenager proclaimed.

"I do! If Ash didn't destroy my bike and I traveled with him freely, I wouldn't mind staying there while he goes to Pummelo Island to face the head of the Orange Crew." That's when the dinosaur wailed to a sight ahead: land. A large complex stood in front of a larger structure that looked like a castle.

"Lapras sees land!" the boy called. Misty and the teen glanced to see the buildings on the new land. The teen realized the location.

"That's Doubloon Island!" Hearing the name, Misty and the boy turned to the teen for more detail.

"Doubloon Island?"

"Tracey, could you explain?" asked Misty.

"Of course," Tracey accepted. "Doubloon Island got its name from pirates who used the island to store their treasures while plundering coastline villages around the world, mostly around the Orange Islands. In fact, their doubloons itemized the name of the island that had been discovered 100 years ago, long after the last of any pirate was seen. Same can be said of other savage sea-fairing people like vikings." The boy didn't believe Tracey about infornation.

"Vikings still exist," he claimed. Misty and Tracey turned to the boy, wondering what he meant. "They're living in Minnesota." Misty, Tracey, the mouse and the spike ball gawked and collapsed from the response. To the boy, their minds had blown. "What? Don't they?" Misty growled as she sat back up.

"Ash, we're talking about real pirates and real vikings, not sports!" she snapped. The mouse angrily squeaked to Ash's nonsense.

"So they don't count?"

"Unfortunately, those 'Vikings' don't," Tracey clarified. "Doubloon Island opened a museum a few years ago to commemorate the history of pirates. Let's stop there and you can see for yourselves." Lapras accepted the idea and swam to the island where they jumped onto land. Ash grabbed a red/white ball and pointed to Lapras.

"Thanks for the ride, Lapras. Get some rest." Lapras transformed into a red light before it zapped to the ball and vanished. The group walked to the museum where a curator greeted them.

"So, you came to learn about pirates, is that right?" he asked.

"We did," Misty confirmed.

"Terrific. Follow me." The group traveled through halls and rooms of pictures of ships and treasures like coins and pieces of gold. Ash reached glass containers full of ragged and water-damaged clothes, including trench coats of different colors. One mannequin wore an eye-patch to go with a ragged red trench. He turned to the curator for an understanding.

"So, did pirates lose an eye to have eye-patches?" he asked.

"No, that's a misconception. Actually, the eye-patches didn't mean pirates were blind in one eye. They used the eye-patches for one eye during the day and one during the night." Ash awed the clarification. "You could say pirates had night vision before medicine labeled it as such." The mouse squeaked in some fear.

"If that's what makes pirates dangerous, I hate to meet them." That's when he saw another case which contained long-barreled pistols and small rifles. Ash and the mouse jumped at the sight of the weapons. Misty and Tracey saw Ash's jump and came over.

"Ash, what is it?" she asked. Tracey saw and came over to the case in question.

"That's a flintlock pistol," he named the long-barreled gun. "And this must be a blunderbuss." The curator patted Ash on the shoulder, reassuring his safety.

"Don't worry," he checked. "Even if those weapons could work, the ammunition's removed for safety purposes." Ash sighed in relief, trusting the curator.

"After the incident with the Game Warden, I don't blame Ash or Pikachu," she recalled. Tracey and the curator wondered about the incident from Misty.

"A Game Warden? Like from the Safari Zone?" Misty bobbed to confirm the guess.

"When we had Brock with us, we entered the Safari Zone where Ash caught a herd of Tauros. The Game Warden was pretty protective of the Safari Zone that he carried a pistol of his own at all times. He even pointed the pistol at Ash for 'ignoring his warnings'." Tracey sympathized with Ash for the incident.

"I can understand wanting to protect the Safari Zone, but that's a little extreme," he murmured. Calm, Ash remembered the castle-like structure behind the museum.

"Is that castle part of the Pirate Exhibit?" he asked.

"The fortress?" the curator corrected. "I'm pretty sure it's been cleaned out but you're all free to check it out." Ash bobbed a nod to go and see the fortress themselves. They entered the dilapidated fortress with the worn wooden door and the stained clay walls.

"This fortress is in better shape than I anticipated," Tracey admired. "Either the clay they used was top material or the staff behind the museum wants to keep its pristine form." Misty clutched her living spike ball, wondering if anything could pop out and scare her.

"I have a feeling there could be a pirate hanging around somewhere in here," she gulped. Ash didn't think it was possible.

"Did you forget what Tracey said in the museum?" he pointed out. "Pirates haven't been seen for a long time."

"Says the one who claimed vikings still exist in a place only you've heard of." Ash paused for a second.

"Wait… are you saying you believe me?" As they continued down the path, they found several rooms mostly bare. Furniture made of wood like tables and chairs still appeared and candle holders, lanterns and chandeliers hung from the walls and ceiling. None of the lanterns and chandeliers were lit.

"I'm guessing these pirates were rather sophisticated."

"Yeah," gulped an uneasy Tracey. "Maybe they weren't as ruthless as we've been told." To Ash, something came to his mind.

"Say, weren't pirates cunning?" he brought up.

"Yeah..." Ash began to examine the holders and lanterns. He tugged one, but nothing.

"I'm thinking they had secret compartments stashed around the fortress. " He tugged two more. Same result. "I believe one of these might trigger one of these doors to open." He continued to tug on more, further annoying Misty.

"What movie makes you think there's some 'hidden treasure' around?" she mulled. He tugged one more candle holder which somehow gave way. A piece of a wall adjacent to the pulled holder opened upward and back.

"A secret compartment!" gasped Tracey. "I think we'll find something in there and give to the museum!" Misty also figured on the discovery about what the museum would compensate.

"They may give us enough for Ash to buy a new bike!" she thought. Her spike ball chirped to the possibility. "You also want to see that new bike we'll ride on, Togepi?" Ash could tell the excitement on Togepi's face.

"Let's go inside and see if we can take it out," he urged before going inside the door. They walked for a few minutes before explosions echoed through the fortress. Oddly, the fortress didn't vibrate. "What was that? Cannon fire?" Noting the lack of vibration, Tracey didn't see it as a big deal.

"They probably installed sound systems to give the feel of what it was back then," he hypothesized. Misty wanted to trust Tracey but felt some of Ash's concern.

"They must have paid a fortune to produce a lifelike experience," she pondered. They continued until they found more doors. Misty opened one with Togepi in her arm and found several ball gowns which looked to be gently worn. "Ah! Look what I found!" The boys looked inside to find the gowns, awing their conditions.

"I can't believe these survived all those centuries in here!" giggled Tracey. "We may have hit the motherload!" Ash looked in another, only to find a desk, a feather in a tiny ink bottle and books on the shelf.

"They used feathers from a Pidgeot, I bet," he assumed before looking pulling one of the books out. Inside had illustrations and words in ink that somehow looked fresh. One illustration was of a giant snake that extended from one page to the other with a dragon-like head and claws near its head. Ash blinked to it. "I don't think I've seen this Pokémon." Looking through, more drawings of more creatures that he blinked to, one being crows with what looked to be fedora hats on them. "Who knew there are more Pokémon than back home." There was even one which looked like a phoenix with a feathered crest on its head. To Ash, nostalgia filled his mind. "Wait, that's the Pokémon we saw on our first day, Pikachu!" The mouse looked and realized the appearance.

("Oh my goodness!") it squeaked.

"This not only explains what the pirates found, but also offers history of what Pokémon they came across." Misty came to Ash, wearing an ivory gown found inside.

"Hey, Ash!" she called. Ash looked to see Misty wearing the discovery. "What do you think?" To Ash, she ruined a piece of history.

"Misty, what are you trying to do, get me to like you?" Misty gawked to the clueless response from Ash. "Besides, it's not gonna be worth much the more you decide to play dress-up." Misty growled to his explanation.

"I bet if you had the chance, you'd be dancing alongside Melody and tout her as your girlfriend, right? Besides, you don't know what someone of beauty looks like if she's in your face." She walked away, leaving Ash and Pikachu stumped.

"Why did she have to act so defensive?" Pikachu shrugged its shoulders, unsure.

"Besides… you have me! I'll be shocked if you have a girlfriend who will agree with you!" Ash shook his head, not wanting Misty to choose for him. "Stupid Ash..." She removed the gown and began to remove another from the rack. That's when she found a piece of concrete protruding out. To her, the fortress had shown some wear. "No surprise this fortress looks to be falling apart." She pressed the brick inward. Ash closed the book, finding new and unknown Pokémon and wanting to see more as he put it in his backpack. That's when the floor under him collapsed. He let out a scream before falling into the hole, Pikachu on his shoulder. The hole looked pretty deep. Tracey came out of a room full of more gold: coins, body wear and other items. Hearing the scream, he and Misty ran in as soon as the trap door closed.

"Ash?!" they called out. No one was sure what happened. Ash and Pikachu hit water below after a long drop. They surfaced in a fast-running stream. Before they could realize what happened, they hit waterfalls and fell. They kept hitting water for a few minutes. After what seemed to be an eternity of falls, they reached a calmer, steadier stream. Gasping for air, Ash and Pikachu found some land to dry themselves.

"What just happened?" he huffed. They shook water from fur and clothes as best they could.

("That was a wild ride,") Pikachu squeaked. Once dried up as much as possible, they headed down a path inside a cavernous area.

"So where did we end up?" Not even Pikachu knew. After a small trek, they soon found an exit. "Here we go!" Just as they found the exit to the cavern, explosions sounded from outside.

("Not good!") Hopping on Ash's shoulder, Pikachu rode out of the cave where they saw rears of two large wood ships floating on the sea with no sail opened. One fired a chorus of cannons at the other and absorbing damage while people in white uniforms jumping from one ship to the other. ("Okay… Reallly not good!")

"I don't like the looks of it either, Pikachu!" Ash's will to stop the attack grew when screams from the attacked ship billowed. "We gotta save them! Charizard, I choose you!" Ash threw another ball up which opened. Emerging was a large orange lizard with wings and a flame on its tail. Ash hopped on the lizard. "Charizard, we gotta help those on that ship."

("We need your wings!") Charizard nodded before flapping its wings and taking flight. Flying, Ash and his creatures hope to save those on board before it's too late.
