Hogwarts was changing, though not in the way Professor Umbridge or the Ministry of Magic intended. Whispers of rebellion echoed through its ancient corridors, and fear wasn't the only thing brewing. Beneath the surface, the DA was transforming into something far greater than anyone had imagined.
In the Room of Requirement, Harry stood in front of an ever-growing group of students. He had called a meeting to introduce the next phase of their training, and the air was thick with anticipation. The room had shifted from its typical layout to resemble a dueling chamber, with practice dummies, enchanted maps of the castle, and defensive diagrams plastered on the walls.
Harry looked out at the crowd of students who had gathered, many more than when they had started. "This is more than just learning spells now," he began, his voice steady but serious. "The Ministry doesn't want us to be prepared. Umbridge doesn't want us to fight back. But we're not just learning to defend ourselves—we're preparing for war. Voldemort is back, whether they admit it or not."
Hermione stood beside Harry, clutching a roll of parchment. "We've been making great progress, but we need to take things to the next level. The Inquisitorial Squad is becoming more aggressive, and we have to be ready for anything."
Ron, standing a little further back, nodded grimly. "We can't rely on anyone but ourselves. That means upping the stakes."
Harry gestured toward the newly crafted training areas. "We'll be practicing advanced dueling from now on. Real combat spells, not just the basics. We're also adding healing magic to the curriculum. If something happens, we need to know how to patch each other up."
Neville, always eager to help, stepped forward. "I'll lead the healing group," he offered, his voice steady with newfound confidence. "Madam Pomfrey gave me some books, and I've been practicing a few spells."
Harry smiled at him. "Thanks, Neville. You're going to be brilliant at it."
The DA members split into their groups: dueling practice in one corner, healing magic in another. Luna Lovegood and Ginny Weasley paired up for shield charms, while Hermione worked with a small group on non-verbal casting. Harry moved around the room, offering tips and encouragement. The once small, secret gathering had evolved into a tightly-knit force ready to take on anything.
As Harry watched his friends, he felt a sense of pride swell in his chest. Despite everything they had been through, despite Umbridge's tightening grip, they were growing stronger. He knew this wasn't just about passing their OWLs anymore. The DA was the last line of defense for Hogwarts, and possibly for the wizarding world.
Meanwhile, in the shadowy depths of the Slytherin common room, tensions were mounting. Draco Malfoy, now the leader of the Inquisitorial Squad, was growing increasingly frustrated. Each attempt to catch Harry and his friends had been thwarted, and Draco was convinced there was a traitor in his midst.
The Slytherins sat around the common room fireplace as Draco paced in front of them, his expression dark. "Someone here is working with Potter," he snarled, glaring at his fellow housemates. "We've set up traps, we've ambushed their little club, and every single time, they manage to slip through our fingers. Someone is feeding them information!"
Blaise Zabini, lounging lazily in his chair, raised an eyebrow. "Are you suggesting one of us is part of Potter's little army? That's absurd, Malfoy."
Draco's eyes narrowed as he looked at Blaise. "Don't play dumb with me. You and Greengrass have been acting strange for weeks. I'm onto you."
Daphne Greengrass shot Blaise a cool look but remained calm. "Malfoy, we've got better things to do than worry about Potter. If you're so obsessed with him, maybe you should take a step back and think about why he's always outsmarting you."
Draco's face flushed with anger, but he didn't have concrete evidence—yet. The constant failures were starting to eat away at him, but deep down, he knew he couldn't act without proof. He stormed out of the common room, leaving behind an air of unease.
As soon as he was gone, Blaise leaned over to Daphne and whispered, "He's onto us. We've got to be more careful."
Daphne nodded, her expression tight. "We'll have to pass on whatever he's planning next to Potter. We can't afford to let him catch anyone in the DA."
For weeks, Blaise and Daphne had been secretly relaying the Inquisitorial Squad's plans to Harry through subtle notes and quiet conversations. It was a dangerous game, but they knew where their true loyalties lay. The DA wasn't just a Gryffindor rebellion—it was a movement for all students willing to fight back, regardless of house. But with Draco growing more suspicious, their position within Slytherin was becoming more precarious.
Back in the Room of Requirement, Harry's focus was sharpening. The DA had come far, but there was still so much more to learn. The Inquisitorial Squad's growing aggression was proof that they were getting closer to exposing the DA, but it was also a sign that the resistance was working. The more the Squad failed, the more they scrambled to maintain control.
"We're not just preparing to defend ourselves from Umbridge," Harry said one evening during a DA meeting. "We're preparing to fight back—against Voldemort, against the Death Eaters, and anyone else who's standing in our way."
The training sessions became even more intense. Dueling was no longer a friendly practice; they were learning spells designed for combat, spells meant to incapacitate, disarm, or even hurt their opponents. Harry taught them everything he could remember from his experiences with Death Eaters and the Triwizard Tournament.
But it wasn't just about offense. The DA also trained in defensive magic. Hermione had been reading advanced books on shield charms and protection spells, and she helped the group strengthen their defensive capabilities. They learned how to deflect curses, create magical barriers, and even disarm their enemies without speaking a word.
Harry knew that no matter how hard they trained, it wouldn't be enough if they couldn't stay ahead of the Inquisitorial Squad. Luckily, Blaise and Daphne continued to pass along crucial information about Draco's plans.
One evening, after an especially challenging session, Blaise approached Harry with a new warning. "Malfoy's planning something big," he said quietly. "He's going to try and catch you off guard during Defense class next week. If he succeeds, it could get you expelled."
Harry's heart sank, but he didn't show it. "Thanks, Blaise. We'll be ready."
Sure enough, Draco made his move during Defense Against the Dark Arts. As the class wound down, he and several members of the Inquisitorial Squad barged into the room, hoping to catch Harry using illegal magic. But Harry, with Blaise's tip, was prepared. He had cast a Concealment Charm on all of his belongings, making it impossible for the Squad to find any evidence of wrongdoing.
Draco's face turned red with frustration as he stormed around the room, barking orders at his fellow Squad members to search every inch. "I know you're hiding something, Potter!" he spat.
Harry just leaned back in his chair, feigning innocence. "I'm just here for class, Malfoy. What's your problem?"
Draco sneered, but after an exhausting search, he had nothing to show for it. He and the Squad were forced to leave, empty-handed once again.
The DA members shared quiet smiles. They had outmaneuvered Draco yet again, and thanks to Blaise and Daphne, they had stayed one step ahead of their enemies.
As the weeks passed, the tension in the school grew thicker. The Inquisitorial Squad's frustration was palpable, but they couldn't seem to catch the DA in the act. Every time they planned a raid or an ambush, the DA was already one step ahead, and Draco Malfoy was starting to unravel.
Late one evening, Blaise met with Harry and Hermione in the Room of Requirement. His expression was serious, his usual calm demeanor replaced with urgency. "Malfoy's lost it. He's convinced there's a mole in Slytherin, and he's getting desperate. We need to be careful."
"Do you think he knows about you and Daphne?" Hermione asked, her voice tight with concern.
Blaise shook his head. "Not yet. But if he keeps digging, it's only a matter of time. You need to make sure the DA doesn't get caught."
Harry nodded, his expression grim. "Thanks, Blaise. You've been risking a lot for us. We wouldn't have made it this far without you and Daphne."
Daphne, who had just arrived, smiled faintly. "We're all in this together, Harry. We can't let Malfoy and Umbridge win."
The Slytherin members of the DA were becoming more crucial than ever. They had their ears to the ground, feeding the group critical information about the Inquisitorial Squad's activities. Their intel had saved the DA on more than one occasion, and Harry was increasingly aware of how much they were risking by working as double agents.
The DA was stronger than ever, and with Blaise and Daphne's help, they were prepared for whatever came next.
