A dimly lit cavernous underground chamber with a colossal obsidian throne, the last man on Earth sits upon it, his figure silhouetted against the faint glow of neon lights embedded in the granite walls, casting an otherworldly aura. He holds a pulsating ball of fire that seems to contain the essence of eternity, illuminating his face with an ethereal glow. The throne room exudes an air of ancient power and mystery, with intricate carvings depicting forgotten legends etched into the stone. The atmosphere is heavy with solitude and the weight of the world's history, as the last remnants of humanity rest on the shoulders of this solitary figure. The style for this scene is a moody and surreal digital artwork, with vibrant colors and intricate details, capturing the contrast between darkness and light
