Pirates of the Magical World I
Captain of the Rogue Cutlass
June 1994
Port Royal, Jamaica
A British fleet of pirate-hunters de-mast the Sea Hawk (man-o-war) and begin boarding, killing all crew. Harry and Dudley are able to save a small number of the crew and escape using magic teleportation crystals (rings); they teleport to Harry and Dudley's sloop, the Rogue Cutlass, hidden in an old smuggler's cave. There, after recuperating, the crew nominates Harry as the Captain.
Angry that the British were becoming so aggressive in 'their' waters, the new Cutlass crew journeys to Port Royal. They try to rally the other pirates into a fleet to fight and fend off the Europeans. After several failures, Harry is approached by a renowned Captain who explains to him how to win their support: by demonstration of ability (fighting, plotting, sailing, and improvising) to show his worth and credibility. Later that night, Harry and Dudley form a plan to not only earn respect among the pirates, but to restore their waters. They give the pirate captains a hint to their plans: when the British fleet leaves the Caribbean, Europe will be ripe for sacking. The Rogue Cutlass sets sail the very next day to prove itself.
September
The Cutlass sails to England and docks secretly in an inlet of Argyll. Harry and Dudley venture into London and Diagon Alley, scoping out the atmosphere and trying to figure how and where they can make the most impact. When they hear of the Triwizard Tournament being hosted by Hogwarts, they see the perfect opportunity. After refining their plans, they return to the Cutlass and set sail for Scotland and the Black Lake upon which Hogwarts sits.
October
During breakfast on the morning after the Goblet of Fire chooses the champions, the Rogue Cutlass suddenly emerges from the Black Lake and opens fire on both the Durmstrang ship and the Beauxbatons carriage. This is meant to not only distract the two schools, but to stall any immediate pursuit teams who might think to use them. Meanwhile, Harry and a raiding party go ashore and attack Hogwarts directly. Among the prizes taken were rare potions stolen from the dungeons, forbidden books from the library, and items from the Trophy Room. But the real prize they were after was the Triwizard Trophy itself, which Harry went after personally. After acquiring it from the Trophy Room and making their way back to the Cutlass, Harry is suddenly beset by teachers, students, and Dumbledore himself. Harry willingly 'sacrifices' himself to give his crew time to escape, getting captured after a short but surprisingly intense battle. With their loot aboard and the defenders starting to fight back, Dudley takes command of the Rogue Cutlass in Harry's absence and they quickly flee back underwater, through the secret tunnel that leads to the open sea.
While a tally was being taken of everything stolen, Harry gets interrogated by the Aurors and Headmasters. When it was discovered he was Harry Potter, they were horrified at what he'd apparently become after his disappearance from Surrey. When it was discovered that the Triwizard Trophy had been taken, they try to force him to reveal where the ship had gone, how to find it, and what he was planning to do with the trophy. He states (quite truthfully) that he no more knew where the Rogue Cutlass was or what the pirates were gonna do with it either anymore since he was no longer captain. Dumbledore sees an opportunity to get Harry to return to England and manages to talk the Aurors into having him 'aid' the Champions. Since without the trophy there could be no Tournament, they needed to get it back and Harry obviously knew the pirates and their habits quite well; he could help them hunt down the ship and reclaim the trophy. It was Ludo Bagman who managed to convince the others to include the Champions in the search, since this would quite obviously be a perilous journey against unknown odds and lands that would test their resolves and abilities to the fullest. Plus, as Champions already chosen, they were magically bound to complete the Tournament in some form or other. Harry and the Champions are taken aboard the English frigate Cartigan's Spirit (much to Harry's amusement) and set out after the Rogue Cutlass with Harry as the navigator.
November-March
They chase the Rogue Cutlass from the North Sea and across the Atlantic coastline, facing all manner of sea creatures and bumping into the fleeing pirates on numerous occasions but never able to fully engage them. They eventually meet up with a large British, German, and French naval force at the Straits of Gibraltar as they enter the Mediterranean Sea. But when they corner the Rogue Cutlass in the Suez Canal, the fleets are suddenly called away by an urgent message from their respective homelands. This leaves the Spirit alone with the Cutlass. Then Harry reveals one tiny fact that none of them ever realized: he'd had the trophy all along. He bargains with the Champions. In exchange for the trophy, the Rogue Cutlass is to be allowed to flee. They accept the deal, believing that Harry was still trapped aboard their ship, but are surprised when he's still able to escape and make it back to the Rogue Cutlass, which promptly disappears under the waters of the canal.
May
The Champions return to Hogwarts in humiliation from Harry's incredibly elaborate deception. What they find upon their arrival is a full-scale naval war between the British magical navy and Caribbean pirates, who'd become increasingly angry and saw the opportunity that the Rogue Cutlass had hinted at. With the general return of the various naval fleets, the pirates suddenly abandon their war and raids, and flee back to the Caribbean. The Champions, though humiliated, all find themselves quite famous after their return from the seemingly 'impossible task' they'd been given. By mutual agreement, the different schools decide to claim no true victor of the tournament since they'd all been fooled.
July
The Champions themselves eventually decide to go in search of the now-infamous Captain of the Rogue Cutlass, for various reasons. Fleur had become rather 'interested' in him over the course of the voyage. Cedric wanted to have an honorable duel to prove once and for all that he was better than some scallywag pirate, Harry Potter or not. And Viktor had become very enamored with sailing and Harry's tales of the pirating life.
(Author's Note) This story was largely inspired by my Atlantis duology, my Queen Anne's Revenge, the new trailers and gameplay hints of Assassin's Creed 4, Sinbad: Legend of the Seven Seas movie, and of course Pirates of the Caribbean.
And this was only meant to be the first of a small series.
So, any takers?
