A wide-angle sci-fi concept scene: a gray-blue metal and concrete mountain industrial base entrance embedded in gray-brown rock cliffs. In the center is a large rectangular arched passage with a "SECTOR 07" sign above it and warm interior lighting creating depth. On the left side of the entrance are pipes, cylindrical equipment, metal storage crates, and railings; on the right are a large mechanical arm structure, fences, tanks, and equipment crates marked with yellow-black warning stripes. The ground is wet concrete reflecting the sky and local lights, with yellow directional markings. The background features steep rock walls and heavy overcast clouds, a cold gray-blue palette with local warm light, realistic materials, cinematic wide-frame composition, no characters.
