A colossal, angular alien structure rises from the edge of a silent black ocean — not obelisk-like, but vast and fragmented, with complex protrusions and stair-like ridges climbing its jagged sides. Ancient stone stairs lead down into the shallow water, partially submerged, slick and glistening. Soft mist rolls over the surface, reflecting faint bioluminescent lights embedded in the stone. A solitary figure stands at the waterline, dwarfed by the monolith, gazing at its towering mass. The sky is overcast and low, soaked in deep teal and muted navy tones, casting a somber palette across the scene. Subtle bokeh glimmers in the foreground from drifting particles and moisture. The image is off-center, with the structure looming from the left, creating a dynamic tension in the composition.
