Brother Harry, Initiate Candidate Ron Weasley, and Initiate Retainer Hermione Granger, all arrive on the ship, and are presented to Librarian Captain Argus. A few hours later, Ron is tested, and found to qualify for the transfiguration into a Space Marine. He is unsure, but decides to give it a shot, he does not really want to leave his family, but is convinced that this is his way of making his mark on the universe.
Hermione of course, has no such qualms, she is eager and ready to go. However she pulls Harry aside later that night and asks if it would be possible to contact her parents one last time. Harry says that its not normally allowed, however they are breaking a few rules to make her a retainer anyway.
A quick tweak of some com gear, mimics the local cell phone network and allows her to dial her parents phone number and speak to them. A tearful hour later, she announces she is ready to start.
The formal response to the duel request was relayed to Minister of Magic, who under orders from Voldemort, published it, and arranged for the duel to take place in one weeks time, near the grounds of Hogwarts, just outside the castle's wards. While Harry could only take one second. No one believed that Voldemort would show up with out his Death Eaters, so the Captain arranged for both tactical squads to be deployed via drop pod, just 1 minute after the start of the duel. Other arrangements were made assuming that Harry won, (which none of the Dark Angels felt fail to happen), a number of servitors were detailed to trace the rest of the horcurxes and destroy them in the meantime
The day of the duel finally arrived. Harry and the Captain had seen to the destruction of the horcruxes, in the ships engines the day before. Riddle Manor, had been found to be a base of some form, and while Riddle himself was not present, the base was taken, using Harry as a field commander. (Almost all Scouts are given overall command of a small routine mission, with an experienced officer for oversight, as a test of leadership, and potential for later promotions.). Riddle Manor falls, without any injuries on the side of the Dark Angels, although several members of the Order of the Phoenix who went with them, were wounded, when they did not follow Harry's orders and remain out of the battle.
The duel of the Ages.. as it had been hyped in the press for days. Was surprisingly short. Meeting on an open field. Harry and Riddle, simply walked up to each other, bowed (as Harry was informed it was proper dueling procedure), and Harry then lined up a sniper rifle shot, and Riddle's head, vaporized.
The death eaters, started advancing.. figuring their numbers would soon overwhelm him. When the two drop pods containing the two Tactical Squads landed, and the Marines took cover and opened fire. None of the Wizard's shields, could stand up to a single bolter round, let alone the hail of fire that 18 Marines, and two Heavy Bolters, could produce. Only a few fatally wounded Death Eaters escaped by port key. None were ever heard from again. Its assumed most port keyed to the Ministry.
Harry, as planned with his Captain and on the advice of some of the Order Members, was to reclaim the ministry, but not as the wizards wanted. A smallish bomb, teleported into ministry, was detonated. Killing most inside, Harry's Sniper rifle took out the few who managed to climb out of the wreckage.
Harry then strode down Diagon Alley, intending to give his farewell speech. (Which the Wizards thought would be a speech to announce he was back to save them all). When Dumbledore confronted him, calling him Dark, as he killed all those people, and even claimed membership of a 'Dark' group. (Of course, the only thing Dark about the Dark Angels is their name.).
Dumbledore pleaded with him to enter training with Dumbledore to 'bring him back to the Light' so they could heal the wounded Wizarding World. When Harry refused. Dumbledore challenged him to a duel, stating that it would be without the silly muggle weapon that Harry used to kill Riddle. Harry asked if swords were acceptable, even allowing Dumbledore to use his wand as well.
A long broad sword appeared in Harry's hand, while he was sub-vocalizing a request for a power sword from the ship. A quick inspection revealed the name "Godric Gryffindor" on the flat, and it glowed with the strange power, Harry had come to realize was Magic. Shrugging, Harry walked up to Dumbledore popping up a solid shield in front of him as Dumbledore fired curse after curse at Harry, all bouncing harmlessly off the shield, and in a single stroke, decapitated Dumbledore. Harry dropped the sword, and turned to walk away, never noticing the sword disappear in a flash of magic.
Silence met this action. Harry stood to give his speech. Now modified for recent events, the crowd, did not seem to object to his announced departure, nor his request to stay a week or three to copy the Hogwarts Library, and other mundane libraries the world over. Knowledge is knowledge after all, it might just help to understand these people better and help in future recruiting efforts.
Three weeks later, Harry and the Captain took off from the Quiddich Pitch, for the last time. While Harry would return many times over his lifetime. He would never again have contact with the Wizards.
There had been questions, loud ones, mostly from Molly Weasley as to where her son had went. Harry simply ignored them. Although a request from Headmistress McGonagall was honored when she questioned where Hermione had went. While a bit sad at losing such a brilliant witch, she understood the honor and opportunity she had been offered. No more was ever said about her absence.
