Dimensional Key in a Wizard Tower - 3D Render

Ultra-detailed 3D render of a dimensional key hovering above an ornate pedestal inside a dim wizard tower. The crystalline key has shifting facets that glow with an inner aurora, cycling colors between violet, teal, and gold. Intricate runes are etched along the key and handle. Surrounding shelves hold leather-bound grimoires, carved stone walls, and arcane sigils glowing softly. Warm amber candlelight and moonlight filter through a cracked skylight, creating volumetric light beams and floating dust. Realistic materials: metal, glass, stone, and wood with subsurface scattering, reflections, micro-scratches, and subtle bloom. A faint portal shimmer appears behind the key, hinting at dimensional travel. Cinematic, photorealistic, high-resolution render in a fantasy setting.
