A/N:In this story, it is assumed that the DA has grown much more powerful than thought, mastering nonverbal magic as well as gaining the ability to duel two Death Eaters together with ease. It is also assumed that Harry has been taught many Advance Spells by Professor Albus , in this story, even underage wizards can use a form of transportation known as Partial Apparition, wherein they turn into smoke, gas and light and travel. This can also be used in duels as all spells except the Killing Curse can be cast even in this is also assumed that along with Harry, Hermione and the Weasley kids, Neville and Luna also know about the Order of The phoenix and also come to stay at Number 12, Grimmauld Place occasionally.
They resolved into human forms as one – Harry, Hermione, Ron and Neville. Harry had had a vision of the Death Eaters finally penetrating the protections of the Ministry of Magic and proceeding towards the Order's weaponry. The Dumbledore's Army had informed the Order of the Phoenix, of course, but too much was at stake to wait for them. Their plan was to hold the Death Eaters as long as possible, at least until the Order arrived. So they had departed from Number 12, Grimmauld Place, shouting down Ginny and Luna's requests to accompany them. They arrived in the Atrium and descended into the Department of Mysteries.
Chapter I – The Corridor
Harry blinked as his eyes got accustomed to the dim light. He knew this place, it led to the weaponry. He started walking towards the door at the end of the corridor they were standing in, ignoring all the other doors at his sides, and urged his friends to follow. But before he had reached the end, a door on his right opened, and in stepped four people – Bellatrix Lestrange, Lucius Malfoy, Antonin Dolohov and Augustus Rookwood.
"Where is the weaponry, Lucius? We have been searching for ages and –" but Bellatrix broke off as she saw the four teenagers. There was a single tense moment of silence, and then booms and bangs and jets of light filled the room. Harry's first act was to cast a Shield Charm over his friend, and then he took up a duel with Dolohov. Ron dueled Rookwood with ease, even grace. Neville struck up a fight with Malfoy, and was dueling nervously, but seriously. Hermione got the toughest – Bellatrix, who had easily struck Hermione twice in a matter of seconds.
Burning with rage as well as concern, Harry conjured huge flames – Dumbledore's invention – that fiercely without needing actual control. Dolohov was easily defeated; he fell to the floor with a shriek and a thud, while Harry directed the flames at Bellatrix, who was shouting "You can't defeat me Mudblood!" Harry replied, with equal contempt, "Together we can!" Bellatrix's eyes widened as she saw the flames, but only for a moment. She swiped her wand once, twice, thrice, and the flames vanished. Now Harry and Hermione began to duel Bellatrix together.
Neville had hexed Lucius, thrice, and Lucius's strength was draining. Ron was coping well, although Rookwood had given him a few minor burns. Harry and Hermione slashed and twirled and swiped their wands at the powerful witch, who had now started moving slowly backwards. Suddenly, with one identical motion, all four of the DA slashed their wands vertically, and golden jets of light erupted from them. Lucius and Rookwood succumbed to these, while Bellatrix managed to turn and enter the room behind her, and only just, where more of her friends were obviously present.
Chapter II – The Library
The moment Harry and the rest entered the next room, they had an impression that if Hermione had entered this room in a different situation, she would have jumped with joy. This, however, was not the case. They walked towards the six hooded figures in front of them, noticing the shelves, atleast 25 feet high, crammed with books as they went.
The hooded party, surely being led by Bellatrix, suddenly charged at them – throwing jets of light. Neville and Ron both started to duel with a Death Eater each, while Harry and Hermione dueled two at once. Bellatrix had still chosen to duel (or kill maybe) Hermione. But Hermione, even though she was in pressure herself, managed to send a curse at one of Harry's opponents – suddenly turning him into a small, cute bunny rabbit. Harry laughed as he aimed curse after curse at his other opponent, finally disarming him and transfiguring him into a water goblet. He then turned upon Hermione's opponent, sending him flying across the room.
Meanwhile, Ron and Neville relied on creativity. They enchanted the books all around them and, as one, directed them to beat their opponents in the face. This was good enough as a distraction for their ambushers, and Ron and Neville shot hex after hex at them, at an incredible speed. When they were done, nothing but the Death Eaters's hair resembled human hair – the rest was like giant, limbless caterpillars. Harry and Hermione, together, were yet again proving to be a great challenge for Bellatrix.
While Ron and Neville set about searching for a way out, they sent spells of astute compatibility at her. If Hermione sent a chunk of ice, then Harry threw a fiery rope at Bellatrix, so that she was able to dodge only one at a time. After several minutes of this, Hermione finally disarmed Bellatrix. Bellatrix screamed, and Harry glance at Hermione, who nodded. Hermione said, "I am going to show you what a Mudblood can do." As one, Harry and Hermione raised their wands. Harry blasted all the books off the shelves and onto Bellatrix. This done, Hermione blasted Bellatrix, so that she flew across, falling unconscious.
Chapter III – The Failed Way Back
Harry said, "I think it is better to get out of this place. It's too dangerous. Anyway, we have already defeated ten – no, nine – of the Death Eaters, including Bellatrix and Dolohov. Let's leave the rest to the Order." "What? And leave the Death Eaters," interjected Neville, "free to gain access to the Giant-Confunding Potion, the Dementor-Repelling Shield, and all the rest of that unbelievable stuff? No, I don't think so." There was a small argument, which ended by Harry declaring that they quit the Ministry, fighting all the Death Eaters along the way. But no sooner had they started on their way back, than twelve figures apparated on top of the bookshelves.
Harry immediately instructed the DA forward and he ran behind the three, casting spells as he ran. At some point, he thought that they were running in circles, but he shook his head as he cast more protective charms in their wake. He had been able to knock out four of the Death Eaters already; he had guessed as much from the muffled footsteps followed by the thuds. But then they turned a corner, and he was positive that they had took a wrong turn. For two huge doors, probably fifteen feet high, stood before them, magically sealed shut.
"Blast the doors, I'll see to the Death Eaters!" yelled Harry, as he turned on his heel and started throwing spell after spell at the pursuing figures. But then he saw Hermione join him, who shouted something like "need help" and "they'll manage". Together, they cursed two Death Eaters into water goblets, and Harry – using another of Dumbledore's ingenious creations – vanished one of them right out the country into a dairy farm in the Prairie. Five to go, thought Harry, and savoured the boom that told him that Ron and Neville had succeeded their work. They ran into the next room, in a very happy mood, when their joy flickered out. They were in a tower, a huge one at that, which was surely enchanted with spells, as it looked very much like a prison. The moment Harry noticed this cost him a huge bang and a black-out.
