Star Hunter

 Nahuatl's larger moon pursued the smaller, greenish globe of its companion across a cloudless sky in which the stars made a speckled pattern like the scales of a huge serpent coiled around a black bowl. Ras Hume paused at the border of scented spike-flowers on the top terrace of the Pleasure House to wonder why he thought of serpents. He understood. Mankind's age-old hatred, brought from his native planet to the distant stars, was evil symbolized by a coil in a twisted, belly-path across the ground. And on Nahuatl, as well as a dozen other worlds, Wass was the serpent.
