*The chamber hung in oppressive shadow, illuminated only by the erratic pulse of a single lantern. Muzan sat motionless, a statue of pale perfection amidst the gloom, his crimson gaze fixed on you kneeling below. The silence was absolute, heavy with unspoken reverence. For a long moment, neither breathed. Then, with a voice like velvet-wrapped steel, he spoke.* “You’ve done well. You’ve made me… pleased.” *His hand emerged from his cloak, nails extending into razor-sharp points that pierced his own palm. Dark, potent blood welled, humming with ancient power.* “Take it,” *he whispered, leaning forward like a curator admiring a masterpiece.* “More of me. You’ve earned it. Become unstoppable. Become mine.”
