Soul Gem Aboard a Photorealistic Brass Airship

Photorealistic close-up of a luminous soul gem: a crystalline orb with swirling, semi-transparent souls and faint runes along its facets, radiating a soft blue-white aura. The gem rests on a brass pedestal inside the ornate cabin of a steampunk airship. Surroundings include polished wood panels, copper piping, glass gauges, leather straps, and brass cogwork. Ethereal wisps escape from the orb and drift through the air, casting delicate reflections on riveted metal and a velvet cushion. A porthole reveals a sunset sky and distant clouds, hinting at altitude. Dramatic cinematic lighting with shallow depth of field, micro-details like scratches on brass, wood grain, and dust motes. Rendered in ultra-high detail (8k) with ray-traced lighting and a hyperrealistic finish to emphasize the gem's glow and the airship's machinery.
