Glowing Obsidian Tablet in a Subway Station

A hyper-detailed photorealistic 3D render of a mysterious ancient artifact embedded in a modern subway platform. The artifact is a carved obsidian tablet with softly glowing emerald glyphs, levitating a few centimeters above a brushed metal pedestal. The surrounding station features tiled walls, steel columns, yellow safety lines, turnstiles, and glowing digital ads. Commuters blur past in the background to establish scale. Wet, reflective concrete catches cool blue and magenta neon lighting, with warm track lights creating contrast. Light shafts filter through the station’s ceiling, casting dramatic shadows. The camera is placed at a low angle with a 28mm perspective, shallow depth of field, cinematic lighting, and ultra-realistic textures to emphasize physically-based materials, micro-surface detail, and subtle film grain. The glyphs pulse faintly, projecting blue light onto nearby surfaces.
