There was a second city, a thick crescent, to the south and east. The old maps placed the Zeggensburg spaceport there, but not a trace of that remained. In its place was what was evidently an industrial district, located where the prevailing winds would carry away the dust and smoke. There was quite a bit of both, but the surprising thing was the streets, long curved ones, and shorter ones crossing at regular intervals to form blocks. He had never seen a city with streets before, and he doubted if anybody else on the Empire ships had. Long boulevards to give unobstructed passage to low-level air-traffic, of course, and short winding walkways, but not things like these. Pictures, of course, of native cities on planets colonized at the time of the Federation, and even very ancient ones of cities on pre-Atomic Terra. But these people had contragravity; the towering, wide-spaced city beside this cross-gridded anachronism proved that. They knew so little about this planet which they had come to bring under Imperial rule. It had been colonized thirteen centuries ago, during the last burst of expansion before the System States War and the disintegration of the Terran Federation, and it had been named Aditya, in the fashion of the times, for some forgotten deity of some obscure and ancient polytheism. A century or so later, it had seceded from or been abandoned by the Federation, then breaking up. That much they had gleaned from old Federation records still existing on Baldur. After that, darkness, lighted only by a brief flicker when more records had turned up on Morglay. Morglay was one of the Sword-Worlds, settled by refugee rebels from the System States planets. Mostly they had been soldiers and spacemen; there had been many women with them, and many were skilled technicians, engineers, scientists. They had managed to carry off considerable equipment with them, and for three centuries they had lived in isolation, spreading over a dozen hitherto undiscovered planets. Excalibur, Tizona, Gram, Morglay, Durendal, Flamberge, Curtana, Quernbiter; the names were a roll-call of fabulous blades of Old Terran legend. Then they had erupted, suddenly and calamitously, into what was left of the Terran Federation as the Space Vikings, carrying pillage and destruction, until the newborn Empire rose to vanquish them. In the sixth Century Pre-Empire, one of their fleets had come from Morglay to Aditya.
