The Slytherin common room was silent, the dim green light from the underwater lake casting faint ripples across the walls. The fire had long since died down, leaving only the faintest embers glowing in the hearth. Gilda sat alone on a cold leather couch, elbows resting on her knees, fingers gripping her temples.

The room, usually filled with chatter, laughter, and scheming, was now eerily quiet. It was far past midnight, and most of the house was asleep. Even Caliban, her ever-loyal companion, was tucked away beneath a plush cushion, his breaths slow and rhythmic as he rested. But Gilda had no such reprieve.

The Masquerade of Moons was on the horizon, and her progress was pitiful.

Most of the first years, bright-eyed and eager to please, had been willing to do whatever she asked. They'd whispered secrets about their classmates, combed through family histories, and delivered detailed reports on blood purity. It was something, but it wasn't enough. They were children—loyal but powerless. She needed more.

Pansy and Theodore remained dutiful, though Gilda suspected more out of fear than true allegiance. Draco and Blaise, however, had become her greatest obstacles. Their resentment had festered since her arrival, and now they were openly working against her. Blaise in particular had taken to calling her a murderer, and worse, whenever he thought she wasn't listening. His words had spread like poison, turning many of her potential allies against her.

Gilda's parents were coming. She had received no further letters, no words of encouragement or instruction—only the cold, foreboding declaration: We will be there.

The thought made her stomach twist. What would they see when they arrived? Their daughter, parading around the school with her reluctant childhood friend and a band of eleven-year-olds? What kind of legacy was that? What kind of leader?

She leaned back on the couch, staring at the ancient book on her lap. The family book had been her lifeline, her guide, her obsession. But there was a passage—one maddening, impossible passage—that had eluded her since she first opened it. The script was ancient, shifting with every glance, as though it resisted her efforts to understand.

But tonight, she was desperate. More desperate than she'd ever been.

With a sharp intake of breath, she stood, sweeping the book and a stack of notes into her arms. Caliban stirred, letting out a low, guttural murmur before settling back down. She gathered him carelessly into the deep well of her hood and made her way into the halls, straight to the restricted section of the library, her wand lighting the way through the dark, echoing corridors.

By the time the sun began to rise, Gilda's desk in the restricted section was buried in books, parchment, and ink-stained quills. Her eyes burned from hours of reading, her fingers smudged with soot from the aged tomes she'd combed through.

Progress had been slow—agonizingly slow. Each fragment of translation felt like pulling teeth, the ancient curse script resisting her efforts at every turn. But she was close. She could feel it.

"Please," she whispered, her voice trembling as she stared at the shifting text. Her hands shook, and she bit her lip hard enough to taste blood. The exhaustion, the frustration, the fear of failure—it all pressed down on her chest, threatening to crush her.

Then, like a key turning in a lock, the pieces clicked into place. Her brain sparked with understanding, finally working with all the pieces of this unsightly puzzle. The final symbols shifted, sheer willpower rearranging the shadowy script into a language she could read, and understand.

She froze, her breath hitching as the translation unfolded before her eyes.

The Harrows, progenitors of blood magic, creators of curses eternal... forged three spells to bind, break, and bury.

Her eyes widened, disbelief flooding her senses. She read it again. And again.

The Harrows—the ancient family whose blood ran through her veins—had created the unforgivable curses.

Her mind raced, her exhaustion momentarily forgotten. The Killing Curse, the Cruciatus Curse, and the Imperius Curse. Spells so dark, so feared, they were named unforgivable. But as her eyes darted over the final lines of the passage, the truth was undeniable. And beneath the revelation of their creation lay clear instruction.

Detailed, deliberate, and chilling in their clarity, the ancient text outlined the mechanics of wielding each curse. The incantations were accompanied by notes on the mental focus required, the emotional alignment necessary to cast them successfully. Each section carried a warning, a sharp reminder that these spells demanded more than just a wand and a word—they required intent.

Deadly intent.

The Killing Curse demanded absolute resolve, the caster's will to end a life as immutable as the laws of magic itself. Without it, the spell would falter, dissipating into nothingness.

The Cruciatus Curse required an unyielding focus on pain, the caster's mind locked onto the suffering they wished to inflict. It was as much about power as it was control—too much hesitation, too much doubt, and the curse would backfire, leaving the caster vulnerable.

The Imperius Curse was different. It was softer, subtler. The caster needed not malice but precision, a keen understanding of the mind they sought to control. Empathy, twisted into domination, was the key to bending another's will. It was a spell of puppeteers, of manipulators, and it required a strange kind of finesse.

Gilda's fingers traced the runes beside each description, their sharp edges glowing faintly as if alive. The instructions weren't just technical—they were visceral, steeped in the understanding of power and the human condition. It was almost as though the book itself was daring her to try.

Her pulse quickened as she read on. This was more than history; it was a blueprint, a guide to the very magic that had shaped her family's legacy. And now it was in her hands.

A single line at the bottom of the page caught her eye, the words etched deeper than the rest, as if to ensure they would never be forgotten:

To wield these spells is to forsake all else. They are a burden, a mark, and a triumph. Use them wisely, or be consumed.

Her fingers trembled as she traced the words on the page. The Harrows weren't just powerful—they were the foundation of fear and control. They had shaped the magical world in ways no other family could claim.

The weight of it all pressed down on her, but beneath the shock, a spark ignited. This was what she needed. Proof of her worth. Proof that her blood, her lineage, was unparalleled.

But what would her parents think? Would they be proud? Was discovery alone enough? Or would they expect her to wield this knowledge, to prove herself worthy of the Harrow name? She knew the answer before she even asked it.

Gilda's mind buzzed with possibilities, strategies forming as quickly as her heart raced. The Masquerade of Moons wasn't just an opportunity anymore—it was her stage.

Caliban stirred again, his eyes glinting faintly as he peered up at her from the shadows of her hood. He let out a low, questioning murmur, and she smiled faintly, her resolve hardening.

"This is who I am, Caliban," she whispered to him. "The true heir to the unforgivable curses."

For the first time in weeks, Gilda felt like she was in control. She closed the book with a sharp snap, tucking it under her arm as she rose. The sun's rays filtered through the high windows, casting long shadows across the library floor.

The library was unnervingly quiet as Gilda stepped out of the Forbidden Section, the ancient tome clutched tightly against her chest. The shadows of the towering shelves seemed to stretch toward her like reaching hands, as if reluctant to let her go. Her mind raced with the revelations she had uncovered, revelations that sent a thrill of power coursing through her veins even as they made her feel as though the ground beneath her had shifted.

It was so intoxicating she barely registered anything else, until a familiar voice cut through her thoughts.

"Gilda."

Eleanor stood a few feet away, arms crossed, her expression an uncharacteristic mix of concern and irritation.

Gilda froze, caught entirely off guard. "Eleanor? What are you doing here?"

"I should be asking you that," Eleanor snapped. "Do you even know what time it is? The first years went with Draco to class because you weren't there to take them. Snape was looking for you in Potions. You've been missing for hours."

Gilda's breath caught, realization dawning. She hadn't just lost track of time—she'd completely forgotten it existed. "I... I didn't realize," she admitted, her voice hoarse.

Eleanor's gaze flicked to the book in Gilda's hands, her frown deepening. "Please don't tell me you've been in there all night." She gestured toward the shadowed entrance to the Forbidden Section. "You're lucky no one caught you."

"I know," Gilda said curtly, her exhaustion sharpening her tone. "But it was necessary."

Eleanor's brow furrowed. "Necessary? For what? What could possibly be worth risking expulsion?"

Gilda hesitated, then stepped closer, her voice dropping. "I can't explain it here."

Eleanor's concern turned to suspicion. "Gilda, what's going on?"

"Come with me," Gilda said, grabbing Eleanor's arm. She began pulling her toward the Forbidden Section, her grip unyielding.

"Gilda, stop—this is insane!" Eleanor protested, trying to resist. "If someone sees us—"

"They won't," Gilda interrupted, her tone brooking no argument. "Just… come."

Eleanor hesitated, then sighed and allowed herself to be dragged into the Forbidden Section. Gilda led her to a secluded corner, surrounded by towering shelves filled with strange knowledge. She turned to face Eleanor, her pale green eyes burning with intensity.

"Listen closely," Gilda said, her voice low but commanding. "I'm about to tell you something that will change everything. But first, I need an answer from you."

Eleanor blinked, taken aback. "An answer? To what?"

"To this," Gilda said, stepping closer. "Are you ready to admit who your people are, who your family is?"

Eleanor's confusion deepened. "What are you talking about?"

Gilda leaned in, her voice softening but losing none of its force. "You know exactly what I mean. Look around you, Nell. Who do you have besides me? Your uncle doesn't care about you. You've got no friends here, not really. And I've been patient, but I need to know—are you going to stand with me?"

Eleanor's mouth opened, then closed again. She struggled to find the words. "Gilda, I don't... Where are you going with this? What are you asking me to do?"

"I'm asking you to choose," Gilda said bluntly. "I've been thinking about the future—about our future."

Eleanor's frown deepened. "What does that even mean?"

"It means I see a world where we've built something extraordinary," Gilda said, her voice growing more fervent. "I see myself standing tall. Taller than I ever dared to. And you're there, too, Nell. Proud, focused, committed. We could have it all. We could rebuild the legacy your uncle is steadily destroying."

Eleanor's throat tightened. The image Gilda painted was flattering, but it was also suffocating. "That's... That's a lovely dream, Gilda. But what about… The Dark Lord, what he stands for? I can't align myself with something so... vile. I can't climb a mountain of corpses just to feel good about myself."

Gilda's lips curled into a faint smirk, though her eyes remained sharp. "I'm not asking any such thing of you. We'll start small."

Eleanor stared at her, her disbelief palpable. "What?"

"With the right people on our side, it will be so easy," Gilda said, her voice almost reverent. "You'll barely have to lift a finger. We'll replace everything that doesn't belong with something better. Something ours."

"You mean, everyone who doesn't belong." Eleanor shook her head. "These are some very sick thoughts you're sharing right now."

"I know," Gilda said plainly. "But I can't do it by myself. What's the point if I'm alone? I need to know if you're with me."

Eleanor hesitated, her mind racing. Gilda's intensity was magnetic, it always had been, but the implications of what she was saying were terrifying. "What exactly are you asking me to do?"

"Stand by me," Gilda said simply. "Be my ally. Be my confidant, my representative, my voice. Help me build a world where we don't have to fight for approval. Where we decide what's right."

Eleanor's voice was barely above a whisper. "And you think we can do that? Become, what? Rulers?"

Gilda stepped even closer, her voice dropping. "Yes. We will do it, no matter what it takes. But I need to know you're with me. Willingly."

Eleanor closed her eyes, her heart pounding. Finally, she nodded, her voice trembling. "I'm… I'm with you. I can't say more than that right now."

A flicker of relief crossed Gilda's face, though it was quickly replaced by something darker. She stepped back and opened the book in her hands, revealing the dense, arcane script. "This," she said, her voice filled with both awe and exhaustion, "changes everything."

"What is it?" Eleanor asked, her unease clear.

"It's a record," Gilda said slowly. "Of my family's greatest accomplishment. The Harrows created the unforgivable curses. The Killing Curse, the Cruciatus Curse, and the Imperious Curse. All of them."

"Gilda!" Eleanor's breath caught in her throat. "You're serious?"

"I translated it myself," Gilda said, her voice tinged with pride. "They didn't just create them—they mastered them. And now, I know how to wield them. Well… I think."

Eleanor's voice shook. "You're talking about spells that destroy lives, Gilda."

"I'm talking about raw power," Gilda said sharply. "The kind of power we'll need to change everything. Or did you forget what we just talked about?."

Eleanor stared at her, torn between loyalty and fear. "Aren't you enough on your own? What are you planning to do with that knowledge?"

"Nothing rash," Gilda said, though the gleam in her eyes suggested otherwise.

Eleanor said nothing, her mind reeling. Gilda's fervor was captivating, but the darkness behind her words was impossible to ignore. For the first time, Eleanor wondered if she had crossed a line she could never uncross.

Eleanor studied Gilda's face, the flickering lamplight casting sharp shadows across her features. There was something raw in her expression—an almost desperate intensity—that Eleanor couldn't ignore. Gilda had always been like this, teetering on the edge of something darker, something more dangerous. And now, with the knowledge she held in her hands, that edge was sharper than ever.

Eleanor thought of Winnick Goldstein, the bright, fiery Gryffindor who had died in a moment of brutality. Gilda had done something unforgivable long before she ever laid her hands on her family's book. She had killed a promising student to secure her place in a world that demanded perfection from her, a world that would have cast her aside without a second thought if she had failed.

But Eleanor understood. She always had. Gilda wasn't driven by malice—she was driven by fear. Fear of failure. Fear of losing the conditional love her family dangled over her head. Fear of being nothing.

Eleanor's heart ached as she watched Gilda carefully, taking in every flicker of her expression, every subtle shift in her stance. This was her oldest friend, the girl she had grown up with, the girl who had held her hand in the dark when the shadows of her own fears crept too close. And right now, that girl was drowning.

She needs me, Eleanor thought, her resolve hardening. More than ever, she needs me.

It wasn't just Gilda who needed saving, though. Eleanor could feel it in her bones. Gilda was becoming something terrifying, something that could hurt far more people than Winnick Goldstein if left unchecked.

I'll do it, Eleanor thought. I'll promise her whatever she needs, say whatever she wants to hear. I'll stand by her side, because if I'm not there, no one else will be able to stop her. And maybe... maybe I can save her. Maybe I can save everyone.

Her voice came out softer than she expected, almost trembling. "Gilda... I'm with you. I promise."

Gilda's eyes softened for just a moment, the fire in them dimming ever so slightly. She nodded, seemingly satisfied. "I knew you would be."

Eleanor forced a smile, her hands clenching tightly at her sides to keep from shaking.

As Gilda turned back to her book, her pale green eyes scanning the ancient script with feverish intensity, Eleanor stepped back, her chest tightening with every breath. She had made her choice, but the weight of it was already pressing down on her, even if it felt like she was doing it for the right reasons.

I'll keep you safe, Gilda, she promised silently. And I'll keep everyone safe from you.

The room was silent save for the turning of pages, but to Eleanor, it felt like the calm before the storm.

Eleanor placed a gentle hand on Gilda's shoulder, her touch firm but careful. "Gilda," she said softly, "we really need to get out of here. Now."

Gilda's eyes remained glued to the book for a moment longer, her mind clearly racing with possibilities. "The Masquerade of Moons," she muttered, as though Eleanor hadn't spoken. "This is it. This knowledge... I can use it. I can make myself a force to be reckoned with. My parents will see it. They'll finally see me as something more."

Eleanor's heart twisted at the words. Beneath all the sharp edges and terrifying intensity, she could see the girl she had grown up with. The girl who had once cried in her arms because she didn't feel good enough. The girl who scared everyone else but, deep down, just wanted to be accepted.

"Gilda," Eleanor said again, her tone more insistent. "We'll figure it out. You'll have all the time you need to prove yourself. But we can't do that if you get caught here. Please, let's go."

For a moment, Gilda hesitated. Then she slowly closed the book and clutched it tightly to her chest. She nodded, the fire in her dimming just enough to allow reason to break through.

Eleanor breathed a quiet sigh of relief and offered a small smile. "Come on. We'll get you back to the common room. I'll let Snape know you're feeling sick. You've been up all night—you need rest."

"I don't need—" Gilda began, but Eleanor cut her off with a knowing look.

"You do," Eleanor said firmly, her voice tinged with both warmth and exasperation. "Even you need sleep, Gilda."

Gilda let out a soft, almost reluctant laugh. "Fine," she muttered. "But only because I know you won't give up."

Together, they made their way out of the restricted section, Eleanor keeping an eye out for any sign of Filch or Madam Pince. Gilda moved silently beside her, the weight of the book in her arms matched only by the weight of her thoughts.

As they stepped into the quiet corridors of the castle, Eleanor glanced at her friend, her expression softening. "You're going to figure this out, you know," she said quietly. "You always do."

Gilda didn't respond immediately, her gaze fixed ahead. Finally, she nodded, her grip tightening on the book. "Of course I will. I have to."

Eleanor didn't press further. Whatever storm was coming, she knew she would be right in the middle of it—and she could only hope she was strong enough to weather it.
