The Room of Requirement had been transformed into a spacious, well-equipped training ground. Shelves lined with magical books and various practice objects were arranged around the room. The students gathered in anticipation, excited for their first official meeting of Dumbledore's Army.

Harry stood at the front, flanked by Hermione and Ron. "Welcome, everyone. I'm really glad to see you all here. Tonight, we're going to start with some fundamental spells that are essential for defensive magic."

Hermione added, "We'll focus on three crucial spells tonight: Disarming, Shielding, and Stunning. These will provide a solid foundation for more advanced techniques."

Harry raised his wand, his voice clear and authoritative. "Let's start with the Disarming Charm, 'Expelliarmus.' This spell is designed to disarm an opponent quickly and efficiently."

He demonstrated, holding his wand steady as he cast the spell—a burst of red light shot from his wand, striking a wooden practice dummy. The dummy's wand flew out of its hand and landed a few feet away. "The key to this spell is not just the magic but the intent. Focus on the opponent's wand or object and channel your will to remove it from their grasp."

Students watched intently as Harry continued. He moved to a nearby student, Parvati Patil, who had stepped forward to try the spell. Her first attempt was a bit shaky, and the wooden wand only wobbled slightly. Harry gently adjusted her grip on the wand. "Remember to visualize the wand being pulled away. Your concentration will make the spell stronger."

Parvati nodded, took a deep breath, and tried again. This time, the wooden wand flew a good distance, and she smiled with satisfaction. "Excellent! Much better," Harry encouraged.

Next, Harry demonstrated the Shielding Charm, 'Protego.' "This spell creates a magical barrier that can deflect spells and physical attacks. It's crucial for defence." He raised his wand and cast the spell, conjuring a shimmering, translucent shield that absorbed a small, harmless jinx from Ron.

"Try to focus on the space in front of you and imagine it being protected," Harry instructed. "The shield will form where you direct your intent."

Ginny Weasley stepped up to practice. She raised her wand and concentrated, but her shield flickered weakly before dissipating. Hermione, observing from the side, approached with a supportive smile. "It takes practice to maintain the shield. Try to picture it as a solid wall that's resistant to all forms of attack."

Ginny nodded, her brow furrowing in concentration. On her second try, the shield held steady, and she looked pleased with her progress.

Finally, Harry moved on to the Stunning Spell, 'Stupefy.' "This spell is used to incapacitate opponents temporarily. It's important for neutralizing threats quickly." Harry demonstrated by casting a vivid blue bolt of light from his wand, striking a practice dummy and causing it to fall over, motionless.

"Keep your wand movements sharp and your focus precise," Harry advised. "The spell should be directed with the intent to stun rather than harm."

Neville Longbottom stepped up next, his face set with determination. His first attempt was a bit too weak, and the bolt of light fizzled out before it reached the dummy. Harry nodded in encouragement and provided a few tips on focusing energy and intent.

Neville tried again, and this time the spell hit its mark. The dummy toppled over with a satisfying thud. "That's the way! Good job," Harry cheered.

"Alright," Harry said, turning back to the group. "Now that you've seen the basics, I'd like to hear from all of you. What specific areas of defensive magic are you interested in learning more about? Any particular spells or techniques you've heard about or want to practice?"

The room filled with murmurs as students began to share their ideas. Ginny Weasley raised her hand. "I'd like to learn more about counter-curses. It's important to be able to undo hexes and curses quickly."

Padma Patil chimed in, "How about stealth and evasion techniques? Being able to avoid detection or escape dangerous situations could be useful."

Luna Lovegood added thoughtfully, "Perhaps we could also cover magical creatures and how to defend against them. Understanding what we're up against might give us an edge."

Neville Longbottom nodded in agreement. "And what about dealing with multiple attackers? Strategies for fighting off more than one opponent at a time would be helpful."

Harry looked around, his expression thoughtful. "These are all excellent suggestions. We'll incorporate these topics into our future sessions. For now, let's break into groups and start practising the Disarming, Shielding, and Stunning spells. Remember, the more you practice, the more proficient you'll become."

The room buzzed with activity as students broke into groups, practising the Disarming, Shielding, and Stunning spells. Hermione and Ron circulated among the students, offering guidance and encouragement. Harry observed, feeling a mix of pride and satisfaction as he saw the students applying what they'd learned.

As the session drew to a close, Harry gathered everyone for a final word. "Great work tonight, everyone. You've shown a lot of promise, and your dedication is what will make Dumbledore's Army strong. Keep practising these spells, and we'll build on them in our future sessions."

The room was filled with lively conversation as students discussed their progress and planned for future practices. Harry, Hermione, and Ron exchanged smiles of accomplishment, knowing that their hard work was laying the foundation for something truly significant.

The kitchen at Grimmauld Place was warm and inviting, with the fire crackling in the hearth casting a soft glow over the room. Sirius and Remus Lupin sat at the wooden table, their tea steaming beside them. Sirius had just finished a conversation with Harry through the two-way mirror and was eager to share his thoughts with Remus.

Sirius leaned forward, a mix of pride and deep emotion on his face. "Remus, Harry's first DA session was incredible. He's making a difference, but it's also clear he's facing some significant challenges."

Remus looked up, his interest piqued. "What challenges are you seeing?"

Sirius's eyes reflected his admiration. "Harry started with the basics—Disarming, Shielding, and Stunning Spells. He demonstrated each one, and then opened the floor for suggestions on what else they'd like to cover. The students came up with some great ideas, like counter-curses, stealth techniques, and even defending against magical creatures."

Remus nodded, a thoughtful expression on his face. "That's impressive. It sounds like Harry's not only teaching but also adapting to his students' needs and interests."

Sirius sighed, a note of concern in his voice. "Yes, but he's also carrying a lot of weight. He's trying to balance teaching, managing the secrecy of the DA, and dealing with his fears. It's a heavy load."

Remus's eyes softened with empathy. "He's following in his parents' footsteps in so many ways. The courage and dedication he's showing remind me of Lily and James. They would be incredibly proud of him."

Sirius nodded, his expression a mix of pride and melancholy. "Seeing him like this, I'm struck by how much he embodies their spirit. It's bittersweet—watching him rise to the occasion while also being reminded of what we've lost."

Remus's voice was gentle but firm. "We need to support him. He's not just carrying on their legacy; he's forging his path. He must know he has our support and that he's not alone."

Sirius's face was resolute. "I've been trying to remind him of that, but he must hear it from all of us. His parents' legacy is alive in him, and he needs to feel that we're backing him up every step of the way."

Remus's gaze was steady. "I'll make sure he knows. We need to reinforce his confidence and remind him of the importance of what he's doing. His strength and leadership are a testament to Lily and James."

Sirius smiled, a mixture of pride and relief in his eyes. "Thank you, Remus. Harry's efforts are making a real impact, and knowing he has strong support from both of us will mean a lot to him."

Remus's face warmed with understanding. "We're all in this together. We need to ensure Harry knows he's not alone and that we're proud of him. His parents would be honoured to see the man he's becoming."

As Sirius and Remus continued their conversation, their shared commitment to supporting Harry was evident. The room was filled with a sense of unity and determination, reflecting their deep bond and their unwavering support for Harry as he navigated the challenges ahead.
