“The land surface is divided into seventeen large island continents. All but the two at the poles are habitable, but only the largest equatorial continent is presently inhabited. The others show signs of habitation in the past, together with a fairly high level of technology that included powered surface and air transport, with radiation traces suggesting that they had fission-assisted electricity generation. Their towns and cities now appear to be abandoned and derelict. The buildings are undamaged, but there are no indications of industrial or domestic wastes either in atmosphere or on the ground, no evidence of food cultivation, and the road surfaces, street paving, and a few of the smaller buildings have been broken up and damaged due to the unchecked growth of plant life. Even in the inhabited areas of the equatorial continent there is similar evidence of structural and agrarian neglect with the associated indications of—”
“Obviously a plague,” Lioren said suddenly, “an epidemic for which they have little natural immunity. It has reduced the planetary population to the extent that they can no longer fully maintain all their cities and services, and the survivors have collected in the warmer and less power-hungry cities of the equator to—”
“To fight a bloody war!” the scout ship’s medic, Dracht-Yur, broke in, its snarling Nidian speech making an angry accom- paniment to the emotionless translated words. “But it is a strange, archaic form of warfare. Either they love war, or hate each other, very much. Yet they seem to have an inordinate respect for property. They don’t use mass-destruction weapons on each other; there is no evidence of aerial bombing or artillery, even though they still have large numbers of ground and atmosphere vehicles. They just use them to transport the combatants to the battleground, where they fight at close quarters, hand to hand and apparently without weapons. It is savage. Look!”
Vespasian’s, tactical screen was displaying a series of aerial photographs of tropical forest clearings and city streets, sharp and clear despite massive enlargement and the fact that they had been taken from a vertical distance of fifty miles. Normally it was difficult to obtain much information on the body mass and physiological details of a native life-form from orbit—although a study of the shadow it cast could be helpful—but, Lioren thought grimly, far too many of these creatures had been obliging enough to lie flat on the ground dead.
The pictures shocked but did not sicken the Surgeon-Captain as they did Dracht-Yur, because the Nidian medic belonged to one of those strange cultures who reverenced the decomposing remains of their dead. Even so, the number of recently and not so recently dead lying about in the streets and forest clearings was bound to pose a health risk.
Lioren wondered suddenly whether the surviving combatants were unwilling or simply unable to bury them. A less sharp moving picture showed two of the creatures fighting together on the ground, and so gentle were the blows and bites they inflicted on each other that they might have been indulging publicly in a sexual coupling.
The Nidian seemed to be reading Lioren’s mind, because it went on. “Those two look as if they are incapable of seriously damaging each other, and at first I assumed this to be a species lacking in physical endurance. Then other entities were seen who fought strongly and continuously for an entire day. But you will also observe that the bodies of these two show widespread patches of discoloration, while a few of the others have skins without blemish. There is a definite correlation between the degree of physical weakness and the area of discoloration on the body. I think it is safe to assume that these two are seriously ill rather than tired.
“But that,” Dracht-Yur ended in an angry growl, “doesn’t stop them from trying to kill each other.”
Lioren raised one hand slightly from the tabletop, middle digits extended in the Tarlan sign of respect and approval. But the two officers gave no indication of understanding the significance of the gesture, which meant that they had to be complimented verbally.
“Major Nelson, Surgeon-Lieutenant Dracht-Yur,” Lioren said, “you have both done very well. But there is more that you must do. Can I assume that the other members of your crew have also had the opportunity of observing the situation below and have discussed it among themselves?”
