A desolate frozen tundra with the ruins of an ancient fortress buried in snow, rendered in Unreal Engine. Jagged ice spikes jut out from the ground, and shattered stone towers rise through the snowdrifts. Blizzards whip across the scene, with snow particle effects creating a chilling realism. The textures highlight frost, ice crystals, and cracked stone. The atmosphere conveys isolation and survival, as though the ruins hide secrets beneath the ice.
