Express Train Speed

Ben looked into the pipe. It was about three feet in diameter and dark as a mineshaft. The inner ceramic surface of the pipe was crusted with stuff he didn't want to know about. That thrumming sound floated up hypnotically . . . and suddenly he saw something. He did not see it with his physical eyes, not at first, but with one buried deep in his mind. It was rushing toward them, moving at express-train speed, filling the throat of this dark pipe from side to side; It was in Its own form now, whatever that might be; It would take some shape from their minds when It got here. It was coming, coming up from Its own foul runs and black catacombs under the earth, Its eyes glowing a feral yellowish green, coming, coming; It was coming.
