Ancient observatory room made of stone, circular layout, domed ceiling, filled with strange mechanical devices combining brass armillary spheres, gears, levers and organic shapes like bones and tendrils, star maps carved into the stone floor and walls, constellations drawn in unfamiliar patterns, a child in simple clothes stands at the center, staring up at a large glowing celestial diagram suspended in midair, expression of awe and slight fear, the machinery around them looks like a mixture of scientific instrument and ritual altar, wires and tubes connecting to unknown objects, Morohoshi Daijirou inspired cosmic mysticism, extremely detailed linework, dense hatching on metal surfaces, monochrome black and white, subtle crack lines on stone, dust particles visible in the air, mood of forbidden knowledge and huge cosmic scale, hints of non‑human design logic in the device structure
