Vast, dimly lit futuristic industrial bay with large cube structures, mechanical arms, and walkways in cool blue light.

A vast, dimly lit underground testing bay stretching into infinity. Thousands of colossal and metal cube chambers 4km by 4km are stacked in precise grid formations, suspended by mechanical arms and magnetic rails, a huge mega structure. The structure feels endless, vanishing into a fog of cold artificial light. Industrial walkways and robotic cranes glide silently along rails between the cubes. The air is filled with low mechanical hums and faint pulses of energy. The camera slowly drifts through the endless maze of cubes, giving a sense of scale and eerie stillness. The atmosphere is sterile, haunting, and awe-inspiring—like a cathedral of forgotten experiments deep beneath the world of S.C.A.R.L.E.T. See more
