Photoreal Enchanted Sword in a Grand Library

A photorealistic scene of an ancient enchanted sword floating mid-air inside a grand, wood-paneled library. The blade gleams with a subtle ethereal glow and faint blue-green runes along its length. An ornate hilt encrusted with gems, a guard etched with mythic motifs. The surrounding shelves are filled with towering leather-bound books on mahogany, a rolling ladder, and warm amber light from brass lamps and candlelight. Dust motes swirl in sunbeams; the polished wooden floor reflects the glow. Focus on the blade with shallow depth of field; background shelves softly blurred into bokeh, rich textures of wood, metal, and velvet, cinematic lighting, ultra-detailed, realistic textures, high-detail rendering.
