Tiers of ledges had been cut and blasted in the native rock, extending from the sea back into the land in a series of giant steps. Each of them was covered with buildings, and here the ancient war had left its mark. The rock itself had been brought to a bubbling boil and sent in now-frozen rivers down that stairway in a half-dozen places, overwhelming all structures in its path, and leaving crystallized streams to reflect the sun blindingly. "So this is your secret city!" But Sssuri shook his round head. "This is but the sea entrance to the country," he corrected. "Here struck the day of fire, and we need not fear the machines which doubtless lie in wait elsewhere." They beached the outrigger and hid it in the shell of one of the ruined buildings on the lowest level. Dalgard sent out a questing thought, hoping to contact a hopper or even a duck-dog. But seemingly the ruins were bare of animal life, as was true in most of the other towns and cities he had explored in the past. The fauna of Astra was shy of any holding built by Those Others, no matter how long it may have been left to the wind, and cleansing rain. With difficulty and detours to avoid the rivers of once-molten rock, they made their way slowly from ledge to ledge up that giant's staircase, not stopping to explore any of the buildings as they passed. There was a taint of alien age about the city which repelled Dalgard, and he was eager to get out of it into the clean countryside once more. Sssuri sped on silent feet, his shoulders hunched, his distaste for the structures to be read in every line of his supple body. When they reached the top, Dalgard turned to gaze down to the restless sea. What a prospect! Perhaps Those Others had built thus for reasons of defense, but surely they, too, must have paused now and then to be proud of such a feat. It was the most impressive site he had yet seen, and his report of it would be a worthy addition to the Homeport records. A road ran straight from the top of the stair, stabbing inland without taking any notice of the difficulties of the terrain, after the usual arrogant manner of the alien engineers. But Sssuri did not follow it. Instead he struck off to the left, avoiding that easy path, choosing to cross through tangles which had once been gardens or through open fields. They were well out of the sight of the city before they flushed their first hopper, a full-grown adult with oddly pale fur. Instead of displaying the usual fearless interest in strangers, the animal took one swift look at them and fled as if a snake-devil had snorted at its thumping heels. And Dalgard received a sharp impression of terror, as if the hopper saw in him some frightening menace. "What--?" Honestly astounded, he looked to Sssuri for enlightenment. The hoppers could be pests. They stole any small bright object which aroused their interest. But they could also be persuaded to trade, and they usually had no fear of either colonist or merman.
