It seemed to Lake that the years came and went ever faster as the Old Ones dwindled in numbers at an accelerating rate. Anders had died in the sixth year, his heart failing him one night as he worked patiently in his crude little laboratory at carrying on the work started by Chiara to find a cure for the Hell Fever. Barber, trying to develop a strain of herbs that would grow in the lower elevation of the caves, was killed by a unicorn as he worked in his test plot below the caves. Craig went limping out one spring day on the eighth year to look at a new mineral a hunter had found a mile from the caves. A sudden cold rain blew up, chilling him before he could return, and he died of Hell Fever the same day. Schroeder was killed by prowlers the same year, dying with his back to a tree and a bloody knife in his hand. It was the way he would have wanted to go--once he had said to Lake: "When my times comes I would rather it be against the prowlers. They fight hard and kill quick and then they're through with you. They don't tear you up after you're dead and slobber and gloat over the pieces, the way the unicorns do." The springs came a little earlier each year, the falls a little later, and the observations showed the suns progressing steadily northward. But the winters, though shorter, were seemingly as cold as ever. The long summers reached such a degree of heat on the ninth year that Lake knew they could endure no more than two or three years more of the increasing heat. Then, in the summer of the tenth year, the tilting of Ragnarok--the apparent northward progress of the suns--stopped. They were in the middle of what Craig had called Big Summer and they could endure it--just barely. They would not have to leave the caves. The suns started their drift southward. The observations were continued and carefully recorded. Big Fall was coming and behind it would be Big Winter. Big Winter ... the threat of it worried Lake. How far to the south would the suns go--how long would they stay? Would the time come when the plateau would be buried under hundreds of feet of snow and the caves enclosed in glacial ice? There was no way he could ever know or even guess. Only those of the future would ever know. On the twelfth year only Lake and West were left of the Old Ones. By then there were eighty-three left of the Young Ones, eight Ragnarok-born children of the Old Ones and four Ragnarok-born children of the Young Ones. Not counting himself and West, there were ninety-five of them. It was not many to be the beginnings of a race that would face an ice age of unknown proportions and have over them, always, the threat of a chance return of the Gerns.
