Disclaimer: I do not own Harry Potter or anything related to or a part of it; I merely have an imagination and an idea for a story that I must get out of my head.

Author's notes: I am taking a few creative liberties with some things that I have not found to be specified in the books (i.e. Bill's age). The character of Sean O'Sullivan and the concept of the Order of St. George are (as far as I know) my creations. This story takes place after "Harry Potter And The Half Blood Prince" and contains spoilers.

Harry Potter and The Knight of St. George Chapter 1: Old Friends

The young twenty-six year old man stood in the King's Cross Station awaiting the arrival of the number 675 train at platform number 17. This was the first time in his life that he had come to this station to meet a Muggle coming on a Muggle transport, and it felt odd to him. He was dressed in his usual Muggle style clothing but still stood out due to his scarred, but well healed, face. He glanced back down at the edition of The Daily Prophet that he held in his hands, the Prophet was still honoring the late Albus Dumbledore even though it had been several days after his demise at the hands of Severus Snape.

"The dog" the man muttered under his breath, "after all that Albus did for him he repays him by stabbing him in the back and murdering him…typical Death Eater."

He was removed from his thoughts when he heard the whistle sounding the arrival of the 675 and looked up to find the train pulling in. He put away his paper and waited for the passengers to get off the train. He wondered if he would recognize him, and how he would take the news of the reason why he had been summoned.

He looked and soon saw a figure twenty-one years of age, standing five feet ten inches high, with his dark blonde hair in a crew cut about half an inch high. He was dressed in a simple hooded monastic cloak and carried a duffel bag gripped by the strap and held over his right shoulder against his back. The only other notable feature was a metal crucifix worn around his neck. The crucifix was made of iron, and was ¾ inch thick with the vertical beam four inches long and the horizontal beam three inches long. The middles of the beams had thin blood red colored beams along the centers that rose about half an inch from the iron ones with a prominent peak in the center.

"Sean!" The man called out.

"Bill Weasley," the other remarked coolly in a confident monotone voice with a thick Irish accent.

The two men stopped and stared at each other for a few moments and then Bill spoke.

"You've gotten bigger," he said referring to the muscular structure of the young man in front of him.

"It has been about four years since we've seen each other" Sean said.

"Too long my friend" Bill answered.

"Indeed" Sean answered simply.

The two of them looked each other over for a few moments before Bill next spoke.

"You must be tired," Bill said to his friend, "and wondering why I called you here," he continued. "Come with me, I'll buy you dinner and we can discuss why I asked you here."

"I'll pay the bill," Sean said, "You look like you've been though a lot." Sean said after looking at the many scars and slashes Bill had on his face and any other part of his body that was visible through his clothes.

"I was a lot worse before the Knights at Dumbledore's funeral gave me the purification water."

They sat down at an outdoor table of a nearby restaurant, Bill ordered a steak, cooked extra rare, and Sean ordered one well done. Bill ordered a Sangria to

drink and Sean ordered milk.

"So," Sean said to Bill, who was biting down a square of his rare-cooked steak, "you called me all the way here from Romania with an urgent message requiring my immediate attention and response just to have a steak dinner with an old mic friend?"

"You're right," said Bill. "I owe you an explanation. You know about the struggle that is going on right now with He Who Must Not Be Named?" Bill continued.

"Aye," Sean responded, "the Dark Lord who is trying to regain power over the Wizard world?"

"Right," Bill answered. "I have come in possession of this message sent by the Dark Lord, it contains details about a plan to form an alliance with several different creatures in an attempt to overthrow those who oppose him and then impose his authority over the world…the entire world…including the Muggles."

"But, if you have the note than that means he knows you have it and will be canceling his plans." Sean responded, still with that air of seemingly unshakeable monotone confidence.

"You're perceptive skills never cease to amaze me O'Sullivan." Bill responded. "But, we did think of that, we caught the owl delivering the note without killing it, copied the message, and then sent the owl on its way. You Know Who will proceed as intended with his plan, but we need to act as though we don't know…the only ones who know about this are myself and the other members of the Order of the Phoenix."

"The Order of the Phoenix?" Sean asked Bill, looking for an explanation.

"It's a group of Wizards who are against the Dark Lord. We operate independently of the Ministry of Magic and move against him in any way we can." Bill responded. "Much like you and the Order of Saint George," Bill added.

"So," Sean began, "what does all this have to do with me?"

"Have you heard of a boy named Harry Potter?" Bill asked Sean.

"No, should I have?" Sean asked.

"I don't think so," Bill responded, "the boy is very well known in my world, but not to the Muggles."

Bill then proceeded to tell Sean everything he knew about Harry Potter. He told him about the beginning and Voldemort marking Harry as his equal when he killed his parents, about the adventures that Harry had with his little brother and their friend Hermione, about his godfather Sirius and his death at the hands of Bellatrix Lestrange, he told Sean about the death of Dumbledore, Harry's defeat at the hands of Severus Snape and Harry's resolve to obtain the Horcruxes and fulfill the prophecy to be the one to destroy Voldemort.

Sean listened intently and carefully and when Bill stopped to take a sip of his Sangria, Sean asked him in his usual monotone Irish accented voice, "But what does all this have to do with me?"

"Sean," Bill began, "These are very uncertain times, we don't know who we can trust, and no one knows who is with You Know Who and who is against him." Bill paused realizing the full plight of the situation, "I would have you read the message" Bill said indicating the confiscated parchment with Voldemort's message, "but to save time and get to the point, I will just tell you that It's orders to Snape."

Sean couldn't help but notice that Bill's tone reflected a large amount of bitterness each time he mentioned Snape. "It says for him to take Bellatrix and find Harry Potter, and bring him to the Dark Lord. He further says that he intends to kill Potter in front of his enemies in order to crush their morale." Bill paused and looked at Sean, Sean could tell that Bill was trying to think of how to word his next statement.

"I am to be some sort of protector then?" Sean asked.

"If you would." Bill answered. "I know that I can trust you, because you are an honorable Knight of the Order of St. George, and that You Know Who wouldn't think of looking for Potter amongst you and the others."

"Plus," Bill continued. "He Who Must Not Be Named has expressed his desire to enlist the Vampires along with the werewolves, Dementors, and Inferi in his cause. And you are the best Vampire hunter in over a century, your tracking skills are second to none, and you possess amazing fighting skills…your strength in body and mind would make even a wizard quake in horror before you. Harry needs new skills if he is to prevail, he needs to go with you to the monastery and learn from you."

Bill paused at the end of this to try and see any sort of reaction in Sean's Prussian-Blue eyes. Sean took another drink from his glass, and paused comprehending all that had been said and trying to picture in his mind what he was being asked to do. "It has taken me sixteen years to get where I am," Sean began, "how much time will I have to prepare the boy?" "Voldemort will strike when the next term at Hogwarts begins…so Harry needs to be ready in about three months."

"You are a great friend Bill Weasley," Sean began, "You are the only friend outside the Order I have ever had in my life…I realize that this needs to happen in order to preserve both our worlds." Sean paused and took a deep breath, and then he answered. "I will do it." He said, "you have my word of honor that I will not let anything happen to this boy and that he will be ready to face his destiny."

"I will hold you to that," Bill responded, "and I know that I will not be disappointed."

"So," Sean said as he paid the bill for their dinners, "when do I meet this boy and when do we leave?"

"You will meet him tomorrow when you come to stay at my parent's home in the Burrow, and you will leave in seven days."

"Why so long?" Sean asked.

"Because it gives you time to get to know Harry, my family, and some of the Order members. Plus, my wedding is in five days…" Bill paused. "And I was hoping that you would be my best man."

"Alright," Sean responded, "unless you want me to wear these robes, I will need to get some new clothes…and congratulations, I look forward to meeting the bride."
