Photorealistic Stone Age Portal in Dawn Light

Photorealistic cinematic image of a Stone Age scene featuring a mysterious portal. In a mossy clearing near a dark cave, a towering arch made of rough granite blocks forms a doorway that glows with cobalt-blue energy. The inner edge ripples with light, swirling mist and carved runes; distant stars and a crescent moon are visible through the portal. A small group of hunter-gatherers in fur robes and leather belts, armed with wooden spears and bone tools, approach with cautious awe while torchlight casts warm amber on their faces. Wet stones, moss, pine needles, and breath mist create tactile, hyper-real textures. The scene balances dramatic, cinematic lighting with natural Stone Age details, and the portal seems to connect to another world beyond sight.
