Harry's heart sank as he surveyed the ruins of number 12, Grimmauld Place. The once grand and imposing home of his late godfather, Sirius Black, lay in ruins, its walls reduced to piles of rubble and ash. The destruction caused by the nuclear fallout was evident, even through the protective enchantments. This was a world torn apart by war, both magical and mundane.

His mind raced as he absorbed the unsettling news he had gathered on his journey. The Muggle World had experienced World War III, resulting in the devastating destruction of London. The familiar hustle and bustle of the city was replaced by a desolate wasteland, where the surviving Muggles appeared gaunt, unhealthy, and desperate.

The encounters with the Muggle survivors were met with suspicion, their mistrust reflected in their eyes as they cautiously answered his questions. They spoke of limited rations, contaminated water, and their unwavering loyalty to the National Reconstruction Party, led by Prime Minister Portia Clay, the Rebuilder of their broken world.

It was then, as he read the slogans plastered across non-magical newspapers, that it dawned on Harry. Portia Clay and the Serene Empress were one and the same. The dark lady who had taken control of Wizarding Britain had extended her dominion into the Muggle world as well. The comfort he took in hoping that these were two separate realms shattered like glass before his eyes.

Despondent and feeling a crushing weight of responsibility, Harry found himself in one of the few remaining places he hated most - Privet Drive. The house that had held him captive for so many years was now nothing more than a smoking ruin, erased from existence by the destructive force of a missile. The mere thought of his obnoxious uncle and aunt brought forth a strange mixture of pity and disdain.

However, amidst the destruction and despair, a passerby recognized Harry's face, pulling him out of sight and into the shadows. To his surprise, it was none other than his estranged cousin Dudley Dursley. The years had not been kind to Dudley, who had lost the weight but gained a haunted look in his eyes.

"Dudley?" Harry whispered, his voice filled with both disbelief and a flicker of hope.

Dudley's face lit up with a mix of surprise and relief. He hugged Harry tightly, their shared history and troubled past momentarily forgotten. "Harry! It's been too long, mate. God, everything's gone to shit, hasn't it?"

Harry nodded, his eyes searching Dudley's face for more answers. "What happened here, Dudley? How did it all come to this?"

Dudley's voice cracked with emotion as he recounted the horrors he had witnessed. The devastation of war, the scarcity of food and clean water, and the constant fear that lingered in the air. He spoke of the rise of Portia Clay and the National Reconstruction Party, whose promises of rebuilding had turned into a dictatorship, just like the Serene Empress in the wizarding world.

"Even in this wasteland, the propaganda and slogans are everywhere," Dudley murmured, his voice tinged with bitterness. "They preach unity, but all they want is control. They've taken everything from us, Harry. Our freedom, our hope. We're mere pawns in their twisted game."

Harry's eyes narrowed as he connected the dots. The similarities between the two worlds, magical and Muggle, were chillingly apparent. Portia Clay and the Serene Empress were one and the same, their sheer hunger for power transcending the barriers between the two realms.

Determined to make a difference, Harry felt a renewed sense of purpose ignite within him. Together with Dudley, he would search for the resistance that was surely forming, united in their fight against the tyranny that had taken hold. They would find his former friends, Ron, Hermione, and all those who stood against this darkness. Hope would not be extinguished, not while he still drew breath.

In this broken world, Harry Potter knew that the road ahead would be treacherous and fraught with danger. But he also knew that he couldn't hide or turn his back on the truth. With Dudley by his side, Harry vowed to be a beacon of light in the darkest of times, even if it meant standing alone against the formidable might of the Serene Empress and her muggle persona, Prime Minister Portia Clay.

The battle for freedom had just begun, and Harry Potter was determined to lead the charge, no matter the cost.
