Voldemort, observing Harry's reaction, continued, "Yes, lovers. Dumbledore and Grindelwald shared a vision of a new world order, where wizards would rule over Muggles, For The Greater Good, as they liked to call it. To do so, they began looking for legendary artifacts. They decided it was time to leave if they needed to begin their plan. At that time, Albus had a brother and a sister. Aberforth and Ariana. Aberforth did not want Albus to leave, as they had to take care of Ariana."
Harry was listening carefully.
For the first time ever in his life, someone was telling him the real truth. So many things were hidden from him. Every time, people would say he was not ready or that he was still a child.
Harry, at that moment, felt that he had made the right decision in listening to Voldemort.
"Ariana, the sister of Dumbledore, based on many sources, said that she was a Squib. One of the proofs was that, compared to Aberforth and Albus, Ariana did not attend Hogwarts. Aberforth was the one taking care of her, but when Albus and Gellert decided to leave, Aberforth became fearful. The duo wanted to kill all Muggles, and Aberforth knew that her sister Ariana was part of this group.
He confronted Albus and Grindelwald. Albus sided with his brother and said that he was willing to kill all except her sister. At the time, Albus's selfishness in protecting only her sister was incomprehensible to Grindelwald. The discussion escalated until a three-way duel broke out between Grindelwald, Albus, and Aberforth. At that time, Ariana, aged about fourteen, tried to stop it by helping Aberforth. But that was the catalyst of the whole event, leading to now. A spell hit Ariana."
Harry's eyes widened as he absorbed the shocking revelation unfolding before him.
"The damage was irreversible, and Ariana Dumbledore, hit by the spell during the chaotic duel, lost her life. If you ask Albus now, he will say that it is unknown whose spell really killed her sister. But deep down, he knows."
Harry wanted to know whether it was Albus who killed her own sister, or Grindelwald? It could not have been Aberforth; Ariana was by her side, based on the tales. Aberforth's spell could not have hit her. It was either Albus or Grindelwald. Harry waited, but Voldemort did not say a specific name.
"Aberforth is still alive, and he has not forgiven Albus for the death of their sister. He still blames Albus as the one who did it. But at that time, Albus changed sides. He made the public aware that Grindelwald had killed Ariana. Grindelwald had to flee the country and was labeled as a dark wizard."
Harry, absorbing the information, felt a surge of empathy for Aberforth.
"Then the war with Grindelwald began. He felt betrayed by Albus. Albus was the one who made him dream and made all the plans with him to kill all the Muggles, but in the end, Albus made himself appear as the hero and painted Grindelwald as the villain.
Albus did not let anyone know that he was the one who pushed Grindelwald to make this war. Then one day, they confronted each other again, and Albus won the duel between them. Albus had successfully used Grindelwald, as he was awarded The Order of Merlin First Class for defeating Grindelwald and protecting the Wizarding world.
Later on, he became the headmaster of Hogwarts. Then slowly he gained the position of Chief Warlock of Wizengamot. But that was not enough; he even gained the authority of Supreme Mugwump for the International Confederation of Wizards.
Don't you see, Harry, what exactly happened?
Albus Dumbledore was hailed as the hero who defeated Grindelwald and climbed the ladder of power and influence. But the truth, my dear Harry, is far more twisted. Dumbledore manipulated the narrative to his advantage, casting Grindelwald as the dark force while concealing his own role in the events that transpired."
Voldemort's words echoed through the silence as Harry's perception of the respected headmaster unraveled.
"He used Grindelwald and manipulated him into pursuing a path that would ultimately lead to his downfall. And when the time came to face the consequences, Albus emerged as the virtuous hero, leaving Grindelwald to bear the weight of his crimes," Voldemort explained, his tone filled with disdain.
Harry, still grappling with the revelation, questioned, "But why? Why would Albus manipulate Grindelwald and let him take the fall?"
Voldemort responded, "Power, Harry. When he saw that he could not do it together with Grindelwald, he did not hesitate to cast away his lover. And then the event of Ariana's death happened. How could he let the world know that he killed his own sister? The power he wanted to protect his family was of no use. But Harry, such an event made him search for power more than ever. Can you guess, Harry, what is the nickname given to Albus? The protector of ...."
Harry whispered the word, almost inaudibly, "Muggles."
Voldemort nodded, confirming Harry's realization. "Yes, The Protector of Muggles. The loss of his sister and the guilt he carried fueled his ambition. What would make a man who has lost his sister to magic hate, Harry? Magic itself. This is purely from my own deduction, but I believe Albus wants to create a purely Muggle world. Only by being the supreme being in magic can one truly destroy magic. I believe he wants to create a world where magic no longer exists and a place where her sister could live as a way to repay her sister."
Harry sat in stunned silence, absorbing the revelation of Albus Dumbledore's true motives and the complex web of deception that had shaped the wizarding world. The hero he had admired, the mentor who had guided him, was painted in a different light. Harry has witnessed personally how Dumbledore has tried to implement Muggle and Muggle behavior into the wizarding world. But he still could not believe Voldemort. Maybe that was not the truth and only the supposition of Voldemort.
"I know you don't believe the idea about the Muggle-only world. But that is not the end of the story. On 31 December 1926 at Wool's Orphanage in London, I was born." Voldemort said.
