A vast cinematic dark sci-fi landscape showing the interior of [an immense alien megastructure cavern], resembling a hollow asteroid cathedral filled with twisting organic-metal arches and colossal ribbed columns. The camera looks across multiple layers of monumental black rock and glossy, wet biomechanical surfaces receding into foggy distance. Concave tunnels, jagged curved supports, and suspended masses fill the void, densely speckled with thousands of tiny warm lights like distant windows embedded in the architecture. Composition is wide, featuring exactly three major light sources: one bright hazy opening on the left, one vertical glowing fissure on the right, and one small distant light near the center. Near the lower left, a lone tiny human explorer silhouette holds a single narrow torch, emphasizing the monumental scale. Palette of monochrome black, charcoal, deep gray, and muted bronze sparks, bathed in [cold white-gray backlight with tiny amber highlights]. Atmosphere is [ominous, mysterious, and awe-inspiring] with heavy volumetric mist, deep atmospheric perspective, and high contrast. Realistic cinematic rendering, ultra-detailed texture, no text, no watermarks.
