Soul Gem Aglow in a Medieval Castle

Ultra-detailed digital painting set in a grand medieval castle hall. At the center, a carved stone pedestal floats on a soft magnetic aura, supporting a soul gem: a faceted orb containing swirling ethereal spirits. The gem glows with inner blues, purples, and emerald greens, casting luminous halos and rays that illuminate the stone floor. The hall features towering arches, ribbed vaulted ceilings, torches along rough-hewn walls, and stained-glass windows that cast fractured prisms of light. Dust motes drift in the amber glow, and suits of armor stand in the shadows. The scene blends photo-realistic realism with digital-art stylization: crisp gem facets, glossy pedestal reflections, painterly brush textures on distant walls, and a radiant glow bloom around the gem. Composition options include a slightly low-angle close-up on the gem with the castle receding in the background, or a wide shot showing the majestic hall. Subtle glyphs etched around the pedestal, tiny sparks as souls drift upward, and a strong contrast between warm torchlight and cool gem radiance. Mood: awe-inspiring, mysterious, ancient; color palette: deep blues, purples, golds, bronzes, and ember orange.
