Dramatic fantasy hiperrealistic image. An ancient an misterious object abandoned by a subway rail inside a dark and dirty tunnel. The object is a strange orb, not bigger than a human, with fallen pieces, with ancient and misteryous runes craved on it. The craved letters shine asi if they were made of silver. The orb almost entirely covered by pieces of fallen wall. There are pieces of wall all over the tunnel. Its very dirty with water drops. A naked woman is getting close to the objetc with a torch. The only source of light in the entire image is the human´s torch.
