The Grey Army

"Tonight, the Grey Assassins must die. It is a new age and we must shed not just our new ways but also our names. Tonight, everything changes. We become not just shadows creeping in the night, but actually be full-fledged warriors who do not have to hide. This is now our time to strike and we will. No longer are we just Assassins; we are now more. Our Assassin past, including how it defines us, will always be a part of us, but it is no longer adequate enough to completely be us as far as our occupation goes. We fight in the day, the night, and everything in between. We fight not just in the mist, fog, shade, tempests, hurricanes, tornadoes, snow, sleet, hail, and torrential downpours. We fight in broad daylight now and let others see us. We are no longer inhibited by our secrecy, but we are now freed with our openness. No longer are we the Grey Assassins! That incarnation of the Order will die once the first bit of blood is drawn, once the first sword falls from us, once we kill our first of many tonight! Do not fall; give it your all! Give your all not for me, not for our cause, but for yourselves! Fight until you are no longer able and still push onward! Do not even let yourself stop fighting as you die! As you fall on the ground, already growing cold, kill at least another! Take one last soldier with you! It is only right for our power, our strength! Give yourself that rare satisfaction and prove yourself to yourself! Prove your name! Our name is no longer the Grey Assassins! Weareno longer Grey Assassins! We are the Grey Army of the Grey Order! We are the Grey Warriors!"

-Chapter Twenty-Four,The Grey Assassins

Chapter One

Harry's sword carried through its path, decapitating the man and ending centuries of tradition amongst not just the Grey Order but also any believer in grey magic.

The man's body fell flat to the ground, spurting blood from the broken neck.

After disembodying the head from the body, Harry kept up the sword's momentum and spun around before slicing the three closest aurors to him. Another managed to raise his wand at him, but Harry used the killing curse on him, sending the spell from his stump of a hand.

So the battle raged on. The group of teenagers turned warriors continued with their dance of death, summoning the elements, casting magic, and using weapons upon their foe. Soon, the aurors began to retreat from the small but devastating attack while their brethren began trying to assault the castle from other sides. More were dispersed into the Dark Forest, but none would ever manage to make it through. Some could be seen trying to cross the quidditch pitch and some others were either crossing the lake or flying by broomstick towards the castle. The defenses installed in the castle, however, sniped the flying aurors off of their brooms or forced the brooms to crash, dropping them from varying high altitudes, guaranteeing their deaths as well. The sniper teams, meanwhile, had eliminated those crossing the quidditch pitch. Those who faced the most horrific deaths by taking alternative routes to Hogwarts were sailing the Black Lake. While they had been facing snipers and soldiers shooting them down in their boats, they were making quite a bit of progress. Suddenly, however, Deus and Basiliscum both propelled out of the water, crushing or eating many of the aurors before submerging once more. After reemerging and sinking twice more, though, they disappeared, heading for the main auror force.

"Oh, thank Merlin." One of the many surviving aurors sighed. Many boats still were sailing for the castle. Just as the survivors regained hope, though, huge tentacles emerged out of the water and began dragging boats filled with aurors into the depths of the lake. When the Giant Squid's assault was over, only driftwood remained atop the surface, the only evidence of the aurors' attempt at the ancient castle.

The aurors seemed convinced that an air assault would lead to triumph over the occupiers of the castle if they attacked in greater numbers. Due to this thinking, swarms of aurors began attacking on broomsticks. The snipers began joining the castle's automated defenses in attacking the attackers. Despite this gain in numbers focused on the enemy, however, Rex, Regina, Jericho, and Acquilina were required in combating them as well. The Gryffindor and Ravenclaw familiars descended from above the clouds forcing the aurors to descend, but the two dragons in turn trapped them by rising from below the swarm. Between the four was a sarcophagus of death; brooms turned into splinters, fiery crisps, or frozen sticks. The aurors fared no better as they too were transformed much like their brooms were or, for a minority of them, were knocked off their brooms to their deaths.

The two basilisks joined by Meles had begun tearing apart the aurors ranks as well, fueling the overall terror and chaos of the battle. Even centaurs had begun pouring out of the Dark Forest with soldiers amongst them, and at the same time the soldiers defending the main entrance of the castle began going on the offensive, charging and joining the fray.

Meanwhile, however, the heart of the battle was still centered with the Grey Warriors. They still were performing their intricate exchange of moves defending and saving one another with the entire goal of eliminating their enemy. They were not holding back much either, using their shadow and apparation abilities with ease amongst their other moves as if the entire fight was rehearsed until remembered by heart.

While one killed an auror, another Warrior was in place to save him or her by killing another Ministry member. Every Warrior's hands were adorned with their favorite weapons, and each weapon showed the evolution of weaponry as well as its cultural differences, as arms from every era and every part of the world could be seen in the hands of the Orderians, who each preferred a different set of weapons.

Finally, the constant pressure and failures on the Ministry's side broke the aurors' will and forced them to retreat. Fudge had already been evacuated shortly after the Grey Warriors appeared. Now, however, there was a mass panic as the aurors literally ran away. Many were still cut down as they fled by the castle's defenses, but the actual living beings defending the castle paused and watched as the enemy fled.

As the last aurors passed through the gate, one looked back at the carnage and piles of corpses with a look of horror before trying to apparate. Instead of apparation, however, death and a 7.62 x 54mmR greeted him out of Harry's Mosin Nagant.

Harry absorbed the rifle into his ring and activated his gauntlet's communication feature.

"Hogwarts is secured. I repeat: Hogwarts has been secured!"

All over the world and especially at the olden castle, cheers rose from the Order and its allies. Some couldn't contain their excitement and joy and quickly quieted themselves for fear of being caught while others forwent their stoic appearances and celebrated.

"Harry, support troops should be arriving any minute." Victor informed over the communicator.

"Thank you. We will begin reinforcing our position here as well. Everyone I would recommend doing the same. As of tonight, The Grey Army has risen and is at war with magical England." Harry couldn't help but let a cocky joy seep into his voice.

Encouragement resounded back at his words.

"Grey Alpha One, out."

Looking up from his gauntlet, Harry saw his comrades and allies starting to clean up the dead bodies scattered around the castle by pushing them into huge boxes that would later be sent out.

"Seamus! Twins!" The teenager turned man called.

"Sir?" The three asked after apparating right in front of him.

"Stock up our munitions and check our defenses. I want this base to continue to grow in might. Who knows when the Ministry will try another assault."

"No counterattack for tonight?" Seamus asked.

"I'm afraid not. I'd rather have us be set up for success rather than rush it. Now, get to work. We will celebrate over breakfast later."

The three grinned and nodded before disappearing into the darkness of the night.

"Hannah?"

"What do you need?" The former Hufflepuff asked.

"I need you to round up some healers and try to help the injured on our side."

"Of course. I'd be happy to." Hannah left without another word.

Shaking his head at the affectivity of his troops, Harry ensured that quarters were made for the Americans that would be stationed at the castle and asked for a report on the casualties from both sides of the battle while also attending to other requirements created after a battle. Among these were resetting the defenses, healing the wounded, rounding up the dead, repairing any structural then cosmetic damage, and strengthening their fortifications. According to Neville, the Orderians, centaurs, soldiers, and house elves had suffered no deaths with only minimal injuries that only required bandages.

After returning from wrapping those who were hurt, Hannah came up to Harry expectantly.

"Hannah, there's no time. I still have much to do, and…" Harry drifted off as Daphne appeared and glared him down into a wooden chair she created behind him.

The former Hufflepuff reached out her left hand and Harry gave her his right arm. Hannah then pulled out her right wand and began casting a silent spell all around the stump, green and yellow streaks streaming down out of her wand. Finally she pushed the glowing tip onto the tip, sending out a final burst of twinkling lime in a vertical circle where the wand and limb met. Quickly, Hannah withdrew the wand and watched the spell take effect.

The fake hand burst off, as the skin that had been cauterized broke free and began growing into a hand. It lay suspended in the air for a second, looking like a deflated balloon but shaped like a hand. Then the bones grew in, providing some structure until the muscle filled in, then the nerves, and finally the nails.

Harry stretched the new hand and his eyebrows furrowed. Hannah saw this look and explained, "It will never be like the old one completely. It's a bit weaker than before but will get back to as great as your left one, and your brain will never fully recognize this hand as its hand. You have full control, but mentally, you will become left-handed probably. I'd suggest getting used to using your left more than your right."

Harry nodded solemnly while Daphne frowned at the news.

"Okay. I will. Thank you, Hannah." Harry started to get up and gloved his new right hand. Daphne banished the chair, and Hannah merely nodded as well and left, going to report in at the Great Hall.

The couple exchanged a sad look before kissing and walking their separate ways. Daphne went to get an ETA on the arrival of the reinforcements while Harry helped move some of the large boxes filled with the deceased into the hangars.

"Sir, what are we doing with them?" A corporal asked.

"We will return them back to their side." Harry began walking away before pausing and answering the question.

"Why, sir? There's barely anything left. Besides, would they give us that honor?"

Harry turned around and glared at the man.

"Just because someone has lower values than you, that does not mean that you have to sink yourself to those values. Your values are what are most important, not what you feel you are obligated."

The soldier stepped back in fear and nodded quickly. "Sir, yes, sir."

"Good. Don't forget this lesson. It is one that transcends military life." Harry then turned and walked away and to a house-elf to arrange the transport of the containers before leaving the hangar.

"Attention." Everyone's communicator rang out. "Reinforcements are on approach. Please clear the runway and make preparations for arrival."

The airfield rushed into an even larger flurry of activity quickly moving to accommodate the incoming aircraft. Three hangars were cleared for each approaching plane almost immediately. Soon after, the first of six blacked out C-130s were spotted in the early morning light.

Each soon arrived down on the ground and proceeded into a predesignated hangar. As the troops already on the ground entered the hangars to help offload the cargo, more troops disembarked off the planes.

"Sir, the reinforcements brought two planes' worth of added weaponry to defend the castle." The captain informed Harry.

"Good, Osborne. Anything else I need to know?"

"Yes. They sent a lieutenant colonel along with the four companies to assist you. Command gave us orders that he is next in command." Captain Osborne replied.

"Bring me to him." Harry said before the officer began leading him to one of the hangars. "Now, does each company also have another captain as well?"

"Yes, sir. No majors are here, however."

"Ok. Now, what is this lieutenant colonel's name?" Harry asked as they entered a hangar and proceeded toward a group of soldiers standing in formation around an officer with a decorative hat on instead of a helmet.

"West." Osborne whispered.

"Lieutenant colonel West, I was unaware that your country was sending an officer of such rank with such power." Harry shook the man's hand, automatically getting a feeling of dislike from the commissioned officer.

"Yes, well, my government wished for someone to be here that accurately represented them. Besides, you need someone to command your five companies of troops."

"Trust me. I can handle any amount of men on my own, but thank you for your assistance. I assure you, though, that your government would have been well represented even if you were absent." Harry less than subtly showed his aggression. "Oh, I should have you know, though, that Captain Osborne here has been given a field promotion to major by me due to his extraordinary bravery and clear thinking in the face of extreme danger. You should notify command and have them send the appropriate markings for him at first convenience."

This obviously did not go by the lieutenant colonel well, but he kept his silence on the matter. "Will do, commander. Now, where are my troops to lodged?"

"My house-elves will guide our troops to the barracks arranged throughout the base. They are set up in different parts of the castle as well as the Dark Forest. Each should easily accompany all the men." Harry retorted. "Now, if you will excuse me."

The newly made Major followed quickly behind Harry as he turned away and opened his gauntlet. "After everyone is situated, all units report to the Great Hall for breakfast."

"By the way, sir… thank you for that promotion." Osborne said after walking with Harry towards the castle for some time after the commander turned off his communicator.

"You earned my respect in that battle, Osborne. You deserved it. No thanks are necessary. Just keep up the good work."

The man nodded. "Yes, commander."

Minutes later, the Great Hall was stuffed with American soldiers, house elves, centaurs, and Warriors. Harry stood in front of his throne, Daphne to his right, their thrones behind them. West was standing off to their left some distance away.

"Last night, the Ministry was here. They were in this same hall, within the walls of this castle, and we pushed them out. We eliminated them!" Harry began, already inspiring his soldiers. "They tried to return, they crossed our borders. They returned and expected to kill us so easily. They expected to roll us over like they have the rest of this country, but we fought back! We fought and sent them running like the cowards they are, their tails between their legs! Now, they know just a fraction of what we are capable of, and they are afraid!" Harry laughed. "They are afraid, and we have not even begun our own attack against them! Now, though, it is our time to attack and make them tremble in their boots! Let us shake them to their core as we take from them their precious and fragile empire they have built for themselves! Our spies are everywhere; every move they make we will know.

"Our spies are even lurking in the other sides' encampment as well. Voldemort believes he is above each and every one of us, but his powers are feeble at best. The only match they are for is for this country's weakness. Now, though, he has found his doom. The 'light' was too weak to destroy him, so now it is our turn to finish the task. Now, it is our time to rid the world of the 'dark' and provide something stronger than and incorruptible unlike the 'light.'

"Last night was the first night of many. The first of our mission to free magical Britain, then all of the magical world, and finally the entire world itself!

"Ladies, gentlemen, and magical creatures alike, warriors for the grey cause… the war has begun!"

From the Great Hall of Hogwarts, a resounding cheer and yell cast out into the early morning light. All around the world, the same feeling of joy and hope was inspired in all the followers of the Grey as they listened in on their communication devices.

The Grey Order and its allies knew it: the war had definitely begun.

Dumbledore and the Ministry knew it as well. With the massive loss they had just suffered, Fudge was meeting with the old man to discuss the plan for the upcoming war.

"Minister, pleasure to see you again." Dumbledore greeted from his desk inside his new office at the Ministry of Magic.

"Please Dumbledore last night was a long night. Let's dispense with the pleasantries. Let me hear your plan for this war." Cornelius Fudge sat down, a worn look on his face.

"Very well…" Dumbledore drifted off before standing up and turning around to a map of Hogwarts he had drawn.

"The first matter is that this group is not one type of force. From what some of the wounded aurors have seen and mentioned, there are the normal troops, which nobody has identified except that they look like regular soldiers but with masks blocking any view of their faces and no identifying marks. They appear to use magic and guns, which obviously shows a very uncivil nature about our enemy. Then, there are the former familiars of the founders, whom I've personally encountered. I believe the founders of Hogwarts empowered their animals to be even greater than they were in nature. The Grey has a griffin from Gryffindor, a badger from Hufflepuff, an eagle from Ravenclaw, and a basilisk from Slytherin, though there also appears to be a mate for the basilisk of Slytherin."

"You're telling me there's two basilisks?" Fudge almost fainted.

"Unfortunately, yes." Dumbledore nodded grimly.

"On top of that, I assume they have at least the centaurs in the Dark Forest and the Giant Squid in the Dark Lake. Also, they possess defenses hidden away on the exterior and possibly interior of the castle as well as the defenses already installed in the castle by the founders such as the stone statues and suits of armor."

"And for this Grey Order?" The Minister interrupted.

"They seem to be very mighty. Obviously, they are led by Harry Potter Hogwarts since he is the heir to the founders and his wife, Daphne née Greengrass, and are composed of students of the school. Their reach is quite uncertain, and, frankly, we do not know much of them besides their blend of dark and light magic with guns and other weaponry. They wear the color of their belief in magic in their armor but are skilled spies, blending in where necessary, as seen by their extensive hiding at Hogwarts. Otherwise, we do not know anything but that they quite deadly and are gaining a following. They must be crushed quickly before they gain a strong foothold in our country or else we run the risk of a very long and destructive war, or even worse, a horrific loss on our part."

"Are you saying that they could, if left unattended, uproot this nation's very government itself?" Fudge asked disbelievingly.

"Minister, I am saying that if they are not stopped soon, then they could do whatever they wished with this nation at a whim." Dumbledore spoke solemnly.

"And, Minister, we are quickly running out of time." Dumbledore paused a moment to let his next words set in with Cornelius.

"The war has already begun."

"Master, I've prepared for you a quick report of what we have gathered on this new force, the Grey Order, as they like to call themselves." Lucius Malfoy bowed before his pretend lord.

"Go ahead, Malfoy." Voldemort hissed from his chair.

The head of the Malfoy family then proceeded to inform the Dark Lord of all the things The Grey Order wanted Voldemort to know, though their powers were greatly undermined by the fact that the Ministry was its opponent in the latest battle in Magical Britain, which Malfoy used to make the force seem quite vulnerable and easy to defeat to the Dark Lord.

"Good. The Ministry will be so much easier to conquer with them already occupied with the Grey." Voldemort chuckled cruelly.

"Now, the war shall begin."

Little did the dark or the light know, however, that the grey had a totally different definition of what the war was to be and encompass. For while the light and dark thought that this was to be contained within only magical Britain, the Grey was going to stretch this war all over the world in both the magical and non-magical sides.

That morning when the first battle ended a war began that the Grey had been planning for its entire existence, and it was overjoyed at the fact that it's plan was finally commencing.

In the snow covered mountains somewhere hidden in Europe, Victor was drinking straight from his bottle of champagne inside the large chamber where the head council was to reside, and the others throughout the base as well as other Grey Bases were celebrating in their own different ways.

The war was now to begin.
