Photoreal Soul Gem in a Forsaken Fortress

Hyper-realistic render of a glowing soul gem embedded in an ancient fortress wall. The gem is a multifaceted crystal the size of a fist, with an inner azure core that swirls with wisps of light. It sits in an ornate metal frame carved into rough, weathered limestone. Surrounding architecture features towering stone walls, moss, and iron torches in wrought-iron sconces, casting warm gold light and deep shadows. Dust motes float in beams of sunlight that streak through a high window. The gem's aura spills out as pale blue streaks that radiate into the air, lighting the surrounding stone with a faint prism of color. Textures are ultra-detailed: chipped stone, glassy facets, polished metal, and subtle wear. Composition from a slightly low angle, shallow depth of field with the gem in sharp focus and the fortress fading into soft bokeh. Cinematic, with a cool blue aura contrasting against warm torchlight.
