A monumental surreal dark fantasy mythcore scene, vertical 9:16. Deep beneath the capital of an ancient empire lies an enormous underground cathedral built around a gigantic living heart. The heart is colossal, larger than a palace, suspended vertically inside a circular stone chamber by immense ancient chains and architectural supports. It is not grotesque and not bloody. Its surface resembles dark weathered organic material mixed with ancient stone, with subtle natural texture and enormous slow pulses beneath the surface. Every heartbeat sends a deep vibration through the cathedral. The chamber surrounding it is an extraordinary fusion of Gothic architecture and ancient engineering: enormous pillars, concentric balconies, stone bridges, bronze mechanisms, carved reliefs and thousands of tiny candles. Generations of priests and engineers have built the entire underground complex around the heart. The heart is the literal source of the kingdom's life. At the center foreground stands a small group of ancient keepers maintaining colossal mechanical structures connected to the chamber. They are tiny compared with the heart. Exactly one ancient mechanism has stopped. A massive bronze gear beside the heart remains completely motionless while every other mechanism continues functioning. The heart is in the middle of a contraction. But for the first time in thousands of years, it fails to complete the next beat. Everything in the chamber appears suspended in anticipation. Above the underground cathedral, visible through a gigantic vertical shaft, lies the distant capital: thousands of warm lights spread across the surface of the earth. The entire kingdom depends on what happens next. The image should communicate that the heart is not merely inside the kingdom — it IS the hidden foundation of the kingdom. Premium cinematic dark fantasy, surreal mythcore, gothic realism, AAA cinematic concept art, monumental underground architecture, extreme micro-detail, physically believable stone, bronze, organic material, chains, candle wax and fabric, atmospheric dust, cinematic volumetric lighting, dramatic rim light, deep shadows, restrained charcoal, cold blue-gray, muted burgundy and antique gold palette, solemn epic atmosphere. Camera positioned low inside the cathedral, looking upward toward the gigantic heart and surrounding architecture. The heart occupies approximately 45% of the frame. Tiny keepers and mechanical structures provide scale. A narrow shaft in the upper background reveals the distant city lights, establishing the connection between the underground heart and the kingdom above. No blood, no gore, no exposed veins in a graphic medical style, no horror creature, no giant monster heart floating randomly, no demons, no angels, no skeletons, no glowing mushrooms, no science fiction machinery, no modern technology, no extra hearts, no duplicated mechanisms, no extra limbs, no malformed hands, no readable text, no symbols, no logos. The heart must feel ancient, sacred and mysterious rather than anatomical horror. Add exactly one subtle white Easter egg on the distant fifth plane: a small white flower naturally growing from a crack in a remote stone balcony, partially hidden and about 15% more visible than surrounding details. Add a small elegant readable signature “Whitezzz” in the bottom-right corner, unobtrusive and separate from the heart.
