Wearily, man and girl struck off across the seas of shifting sand. Great dunes blocked their way. Some they circled, others must be climbed laboriously.
From the top of a huge, wind-ribbed billow, Newlin stared at a pale flickering in the dust ahead. In all other directions stretched endless humps and hollows. But before him lay a great wind-scoured hollow of bare rock. Beyond that, crowning a series of low hills, which must have thrust above water line in this shallow part of the ancient, vanished sea, were ruins.
Even as ruins, the city was spectacular. Massive columns had eroded slowly into stone toothpicks. Walls crumbled into formless heaps resembling the dunes. A few outlines of smoothed blocks and shattered lintels huddled the ground, half hidden by the encroaching sand. Details had vanished eons ago, but something still remained to tantalize imagination. The few buildings that still stood, and the soaring, fragile towers evidenced an engineering civilization of staggering proportions. Surface dimensions were still tremendous, and the city itself must have been of first importance, covering hundreds of square miles.
"Our city," said Songeen.
Newlin glanced quickly behind. Still distant, but moving very rapidly was the string of dark objects that could only be sandsleds of the pursuit. One tiny figure, scarcely visible, was far in advance of the others. The robot tracker.
He gestured. "They're covering three miles to our one," he told her grimly. "We'll try to reach the city before they catch up with us. Perhaps we can hide out among the ruins, and—with luck, booby-trap the tracker. If there's water, we can hold out for quite a while."
Songeen nodded crisply. Her voice was strained with emotion and fatigue. "As fugitives my people abandoned this city. Now, as a fugitive, I return."
Then she was off, running awkwardly, the cumbersome suiting of her protection armor giving her bounding strides the laughable appearance of a lumbering teddy-bear.
Descent into the hollow was riding a series of miniature sand avalanches. Each step buried the foot deep, but the sand gave way and slipped in loose spills. His boots struck hard on rough, bare rock. He grunted, fought for balance, then sprawled heavily. She helped him up, then took off again. Newlin followed.
