Hao Ren looked back to where they came from and the path in the fog had disappeared. In its place was a layer of black mirror with a ripple effect across it, like a painting in the air stretching out of a building. It was ten metres wide or so and a black band, which looked like it was drawn with oil paint floated around the edges. He was curious. He touched it but his hand felt nothing. But when he poked his head through the mirror, he saw that the path was still there. Hessiana spoke snappily from behind, "If you want to go home, use this mirror and just follow the path. You guys have a marking; as long you you don't wander into the fog, you'll be safe. There's an ancient one guarding the entrance and the exit between the Shadowy Divide and the real world, just give him a heads-up then you'll be free to come and go. However, you're not allowed to bring anyone in. Your marking is meant only for you. Outsiders who trespass the second level of the shadow space will surely die."
