The frigid air of the cave immediately brought tears to Sirius's eyes. He cast a vigilant and wary gaze around him, acutely aware of his surroundings. Kreacher had materialised abruptly, vanishing him without uttering a word.
Before him materialised a haunting scene, familiar and yet otherworldly. A dark, contorted figure lay convulsing, shattered. It was in that precise moment that he grasped the grim truth. He rushed towards the figure, heedless of the peril that might await him.
"Please, let me help," he implored.
The two brothers exchanged frantic glances, enveloped by the cavern's obscurity, as time itself seemed to slow. Despair filled the void, suffocating.
"I am sorry, Regulus," Sirius murmured, his voice faltering.
He needed to bid farewell to the brother he thought he would never see again, the one he had lost forever. It was a loss beyond measure, leaving a void that only the presence of one brother could fill.
As Kreacher watched in silence, his eyes filled with tears, the surviving brother looked at him, heart heavy with loss. "I shall miss him, Kreacher."
Now, all that remained was to discover a means of ridding himself of the dark mark, to honour his brother's sacrifice.
