An original deep-sea research base on an alien ocean world, with modular pressure habitats anchored along a trench wall, a transparent observation dome, two small submersibles and delicate instrument towers. Above lies a luminous ice-like surface; distant volcanic vents and slow drifting bioluminescent organisms establish scale without monsters. Wide cinematic establishing shot with the base in the lower third and an immense cobalt water column. Turquoise biological light contrasts with warm habitat windows. Pressure-rated ceramic shells, titanium ribs, thick glass and mineral sediment, believable engineering and coherent scale, no logos, no text, no watermark.
