Itachi Uchiha, Luna Lovegood's husband, stood in the grand hall of Hogwarts, his eyes reflecting the moon's silver light. His calm demeanor contrasted with the turmoil around him.

The room was eerily silent after Itachi's demonstration of his domain expansion: Moon Reader. The lingering magic in the air was palpable.

Dumbledore, the headmaster of Hogwarts, broke the silence. "What was that realm?" He asked, his eyes twinkling with curiosity.

Itachi explained, "It's a domain expansion, my ultimate trump card." His voice echoed through the silent hall.

Hermione Granger, the brightest witch of her age, asked, "How did you make it?" her eyes filled with curiosity.

"You construct it by expanding your innate domain with chakra while using a barrier to construct it in a separate space," Itachi explained.

Hermione, eager to understand more, asked, "What's your domain ability?" Her eyes shone with the thirst for knowledge.

"Moon Reader allows me to revert any action to zero," Itachi began, "For instance, within the domain, Voldemort was just standing there."

Luna Lovegood, Itachi's wife and a unique witch, nodded in understanding. "Yes," she said, acknowledging his explanation.

"He was casting spells at me, but Moon Reader kept nullifying it," Itachi continued. "It reverts everything back to a neutral state."

Itachi then revealed the final ability of Moon Reader. "When someone dies in my domain, they experience infinite outcomes of death due to it reverting back to zero," he said.

Ron Weasley, Hermione's best friend and partner, asked, "So is Voldemort alive?" His red hair contrasting the seriousness in his voice.

"Yes and No," Itachi replied, "He is trapped in an endless cycle of death and rebirth." His words carried a certain finality.

The silence that followed was heavier than before. Voldemort, the most feared dark wizard, was defeated in a way no one had ever imagined.

Dumbledore's eyes sparkled with a glint of appreciation. "Itachi Uchiha, you have shown us a power beyond our understanding."

Itachi merely nodded, acknowledging Dumbledore's words. He had done what was necessary. The battle was over.

Luna stepped forward, her hand reaching for Itachi's. Their fingers intertwined, a silent promise of support echoing between them.

Hermione, with a thoughtful expression, turned to Ron. "This changes everything," she whispered. "The wizarding world will never be the same."

Ron nodded, his gaze lingering on Itachi. "I guess, this is the beginning of a new era," he murmured, his eyes reflecting a mix of fear and admiration.

Dumbledore, his eyes filled with wisdom, looked at Itachi. "This power of yours, it's a great responsibility," he said, his voice calm and steady.

"I understand," Itachi replied. He knew the weight of his power. He had always known.

Dumbledore gave him a nod, a silent acknowledgment of Itachi's resolve. The grand hall was once again silent, as everyone pondered the magnitude of the moment.

Luna, standing by Itachi's side, squeezed his hand gently. Together, they faced the uncertain future that lay ahead.

Hermione and Ron shared a look, their eyes reflecting the shared understanding of the magnitude of the situation. They knew the world was forever changed.

Itachi looked at Luna, his wife, his partner. He knew they had a long journey ahead. But he was ready. Together, they would face whatever came their way.

Dumbledore, a wise old wizard, looked at the young couple. He knew they had the strength to face the challenges that lay ahead. And he believed in them.

Hermione, always the scholar, was already thinking of the implications of Itachi's power. She knew this was a major turning point in magical history.

Ron, ever the loyal friend, stood by Hermione's side. He too realized the magnitude of the situation. It was the dawn of a new era.

Luna and Itachi, hand in hand, looked at the stars. They were ready for whatever the future held. They had each other, and they had the Moon Reader.

Dumbledore, Hermione and Ron watched the couple. In their hearts, they knew that the world had changed. But they also knew that they could face it, together.

As the night deepened, Hogwarts stood tall, a beacon of hope in the darkness. And within its walls, the seeds of a new era were being sown.

Itachi and Luna, Dumbledore, Hermione and Ron, they were the torchbearers of this new era. Together, they would navigate the challenges that lay ahead.

The Moon Reader's Domain had sealed the fate of Voldemort. But it had also opened a new chapter in the history of the magical world. A chapter filled with hope and possibilities.

As the moonlight streamed into the grand hall, Itachi and Luna, hand in hand, looked at the future with determination in their eyes. They were ready. The new era had begun.

The grand hall of Hogwarts was silent once again. But this time, it was a silence of hope, of anticipation, of a new beginning. It was the silence of the Moon Reader's Domain.
