At first, the two towers seemed as sound as when they had been built; gradually it became apparent that one was broken at the top. For the most part, the smaller buildings scattered widely around them were standing, though here and there mounds of brush-grown rubble showed where some had fallen in. The spaceport looked good--a central octagon mass of buildings, the landing-berths, and, beyond, the triangular areas of airship docks and warehouses. The central building was outwardly intact, and the ship-berths seemed clear of wreckage and rubble. By the time the _Nemesis_ was following the _Space Scourge_ and the _Lamia_ down, towed by her own pinnaces, the illusion that they were approaching a living city had vanished. The interspaces between the buildings were choked with forest-growth, broken by a few small fields and garden-plots. At one time, there had been three of the high buildings, literally vertical cities in themselves. Where the third had stood was a glazed crater, with a ridge of fallen rubble lying away from it. Somebody must have landed a medium missile, about twenty kilotons, against its base. Something of the same sort had scored on the far edge of the spaceport, and one of the eight arrowheads of docks and warehouses was an indistinguishable slag-pile. The rest of the city seemed to have died of neglect rather than violence. It certainly hadn't been bombed out. Harkaman thought most of the fighting had been done with subneutron bombs or Omega-ray bombs, that killed the people without damaging the real estate. Or bio-weapons; a man-made plague that had gotten out of control and all but depopulated the planet. "It takes an awful lot of people, working together at an awful lot of jobs, to keep a civilization running. Smash the installations and kill the top technicians and scientists, and the masses don't know how to rebuild and go back to stone hatchets. Kill off enough of the masses and even if the planet and the know-how is left, there's nobody to do the work. I've seen planets that decivilized both ways. Tanith, I think, is one of the latter." That had been during one of the long after-dinner bull sessions on the way out from Gram. Somebody, one of the noble gentlemen-adventurers who had joined the company after the piracy of the _Enterprise_ and the murder, had asked: "But some of them survived. Don't they know what happened?" "_'In the old times, there were sorcerers. They built the old buildings by wizard arts. Then the sorcerers fought among themselves and went away,'_" Harkaman said. "That's all they know about it." You could make any kind of an explanation out of that. As the pinnaces pulled and nudged the _Nemesis_ down to her berth, he could see people, far down on the spaceport floor, at work. Either Valkanhayn and Spasso had more men than the size of their ships indicated, or they had gotten a lot of locals to work for them. More than the population of the moribund city, at least as Harkaman remembered it.
