Chapter 1 Ariana

The Dumbledore household was quiet, the kind of stillness that came after the world's chaos had worn itself out. Harry sat at the small table in the kitchen, the soft light of the fire casting long shadows on the stone walls. Across from him, Ariana was carefully stirring a cup of tea, her movements slow, deliberate, like she was afraid to break the silence.

Harry watched her, wondering how it was possible that after all this time, she still seemed like a mystery to him. It had been nearly two years since he'd found himself here, in this different time, and in that time, Ariana had become… everything.

"How's the tea?" she asked, not looking up. Her voice was soft, but there was something underneath it, something strained.

"It's perfect," Harry said, trying to keep his tone light. In truth, he hadn't even tasted it yet.

Ariana looked up then, her pale blue eyes locking with his. There was a sadness in them that he recognized too well. She had been trying to hide it from him lately—the worsening effects of the Obscurus.

"I've been feeling it again," she admitted quietly, her hands trembling as she placed the spoon down. "It's getting stronger, isn't it?"

Harry's heart clenched. He didn't know how to answer, but he knew lying wouldn't help. "Yeah," he said gently. "But we'll find something, Ariana. We've still got time."

She gave a small, sad smile. "You always say that."

Ariana sighed, glancing away from him. "Sometimes I wish I could just be normal," she said, her voice barely above a whisper. "To not have to worry about… this." She gestured vaguely toward the window, as if the world outside held the answers to her problems.

"Normal?" Harry echoed, leaning forward. "But you're not normal, Ariana. You're extraordinary. You're so strong."

She met his gaze, and he could see the flicker of doubt in her eyes. "Strong?" she asked, a hint of bitterness creeping into her voice. "I don't feel strong. I feel like I'm a burden to everyone. To you."

"Never," Harry insisted, his heart racing. "You're not a burden. I chose to be here, to help you. You're the reason I—" He stopped, realizing he was about to reveal too much.

Ariana tilted her head, curiosity dancing in her eyes. "The reason you what?"

He hesitated, torn between the truth and the weight of his secret. Instead, he took a deep breath, forcing a smile. "The reason I keep searching for a way to help you. Because you deserve it."

For a moment, the air was thick with unspoken words, their connection deepening in the quiet tension. Then, just as quickly, the moment passed, and Ariana looked away, a shadow crossing her features.

"Harry," she said softly, "I don't want to be a source of pain for you."

He took her hand "You're not," he reassured her. "I want to help you, not just because I feel like I have to, but because I want to. You matter to me."

Ariana's eyes widened slightly, a blush creeping into her cheeks. "I… you matter to me, too. But I don't know if there's a way out of this."

"Maybe not yet," he replied, a determined spark igniting in his chest. "But I won't give up on you. We'll figure this out together."

As they shared a quiet moment, the weight of her struggle loomed heavy, but so did the flicker of hope that had begun to take root between them.

—

A few days later, the atmosphere in the Dumbledore household was tense but charged with purpose. Harry had gathered every book and scroll he could find, spreading them across the kitchen table. He could sense Ariana's apprehension as she watched him sift through the pages, his fingers trembling with both excitement and fear.

"Are you sure you want to do this?" she asked, biting her lip as she glanced at the chaotic assortment of texts. "What if we don't find anything?"

Harry paused, looking up at her with resolve. "We have to try. There has to be something here that can help. If we keep searching, we can find a way to stop it."

"I want to believe that," she said softly, "but…"

"But what?" Harry pressed, not willing to let her doubt take root. "Ariana, we can't give up. You're too important for that."

She sighed, moving closer to the table. "I just don't want to put you through this. You've already done so much for me."

He shook his head. "You're worth it. Every moment spent trying to help you is worth it."

As they pored over the texts, they stumbled upon an old tome, its pages yellowed and worn. Harry flipped through it, his eyes widening at the words inscribed within.

"Look at this!" he exclaimed, pointing to a passage. "It talks about Obscurials—how they can sometimes be cured through a special ritual, but it's dangerous."

Ariana leaned in, reading the text. "But it says it requires a powerful bond between the one casting the spell and the Obscurial. Do you think—"

"Maybe we can try it," Harry interrupted, a rush of adrenaline coursing through him. "If we're connected, it could work."

"Connected?" she repeated, her brow furrowing in thought. "Harry, you know I don't want you to put yourself in danger for me."

"I'm not afraid of danger," he insisted, the determination in his voice surprising even himself. "I want to help you, Ariana. Whatever it takes."

The warmth between them shifted, becoming electric as their eyes met. For a brief moment, the chaos outside faded away, leaving only the two of them in their shared determination. But underneath it all, Harry could feel the weight of his secret pressing down on him, a shadow lurking in the back of his mind.

"Let's try," Ariana said finally, her voice steadying as she took a deep breath. "Together."

"Together," he echoed, but as he spoke, a part of him knew that his promise carried a cost he wasn't ready to face.

Just as Harry and Ariana leaned closer to the old tome, the door creaked open, and Albus stepped into the room. His gaze swept over the scattered papers, and a frown crossed his face.

"What are you two doing?" he asked, his voice laced with concern. "You know nothing can be done for her."

Harry felt the heat of Albus's gaze on him, the unspoken tension hanging in the air like a storm cloud. "We're looking for a cure," he replied, refusing to back down. "There has to be something here."

Albus's expression softened as he turned to Ariana, but a shadow flickered across his features as he looked back at Harry. "I admire your tenacity, Harry, but I've tried. I've spent years searching for a way to help her, and all I found was heartache."

Ariana's eyes darted between her brother and Harry, tension crackling in the room. "Albus, please. We can't give up. Harry believes we can find something."

"Belief isn't enough," Albus said, his voice growing firm. "What you're looking for is dangerous, Harry. I don't want to see any of you hurt."

Harry met Albus's gaze, unflinching. "I won't stop searching. Ariana deserves better than this."

Albus's expression turned colder, the jealousy seeping into his demeanor. "And what do you think you can offer her that I cannot? You're just a boy, Harry. My sister deserves someone who can truly protect her."

"Albus, that's not fair," Ariana interjected, her voice rising slightly. "Harry has been here for me when no one else has."

"Perhaps," Albus replied, his tone clipped. "But he's not family. You're not seeing the bigger picture, Harry. This isn't just about you and Ariana."

Harry's heart raced, frustration bubbling beneath the surface. "I'm not trying to take her away from you. I just want to help her!"

"And that's the problem," Albus said, his voice dropping to a whisper, his eyes filled with a mixture of worry and something darker. "You're willing to put yourself in danger for her. You don't understand what's at stake."

"Then help us!" Harry shot back, his voice rising with determination. "If you love her as much as you say, help us find a way."

The room fell silent, the tension thick enough to cut. Ariana's gaze flitted between the two, her brow furrowed in thought.

Finally, Albus sighed, a mixture of defeat and frustration crossing his features. "I want to protect her. But if you're both set on this course, I can't stop you. Just promise me you'll be careful."

"Always," Harry promised, feeling a swell of hope despite the lingering shadows in Albus's eyes.

As Albus left the room, Ariana turned to Harry, a mixture of gratitude and concern in her gaze. "Are you sure about this, Harry?"

He nodded, resolve strengthening within him. "We'll do this. I won't let you go through this alone."

The candle was almost gone and dimly lit room, the air thick with an almost tangible silence. Ariana long ago asleep, her chest rising and falling gently, a fragile beauty that took Harry's breath away. He watched her, the weight of his thoughts pressing down like an anchor.

Feeling restless, Harry began rifling through the ritual for a thousand time, his fingers gliding over the pages to fully understand what he is about to do for her. There was a thought, something Harry couldn't get rid of, a feeling that if she knew, she wouldn't let him do this, never. But there is just no other way, she couldn't go on like this anymore the attacks became more frequent and the more often they happened she felt more agitated, and it led her to another seizure and each time stronger.

Hours passed as he again immersed himself in the text. He decided to snatch the page with the spell, so she won't find out. Auferatdolor - a spell designed to take pain from one person and transfer it to another.

His heart racing as he turned to Ariana. She looked so peaceful, so serene, and yet the shadows of her suffering loomed large in his mind.

Taking a deep breath, he crossed the room and knelt beside her bed, the page crumpling in his hand. He brushed a few strands of hair from her face and gently stroked her cheek, his fingers trembling at the warmth of her skin.

"You're the best thing that ever happened in my life," he whispered, his voice barely above a breath. "And I will never let you suffer like this anymore."

The determination in his heart swelled, drowning out the doubt that had plagued him for so long. He knew the risks, the uncertainty, but seeing her like this—fragile and vulnerable—filled him with an unwavering resolve.

With one last look at her serene face, he knew what he had to do.

As he gathered his courage, the weight of the page pressed against his palm, Harry vowed that he would do whatever it took to save her, even if it meant embracing the darkness within himself.
