"Walk straight ahead," said a voice, speaking the language of his own race, and he felt a spearpoint touch the back of his neck.
And straight ahead he walked, feeling his sandals scrape on the stone floor of the cave, until they came to a place where the floor tilted upward. The pitch was steep and the stone was so slippery that Cororuc could not have climbed it alone. But his captors pushed him, and pulled him, and he saw that long, strong vines were strung from somewhere at the top.
Those the strange men seized, and bracing their feet against the slippery ascent, went up swiftly. When their feet found level surface again, the cave made a turn, and Cororuc blundered out into a firelit scene that made him gasp.
The cave debouched into a cavern so vast as to be almost incredible. The mighty walls swept up into a great arched roof that vanished in the darkness. A level floor lay between, and through it flowed a river; an underground river. From under one wall it flowed to vanish silently under the other. An arched stone bridge, seemingly of natural make, spanned the current.
All around the walls of the great cavern, which was roughly circular, were smaller caves, and before each glowed a fire. Higher up were other caves, regularly arranged, tier on tier. Surely human men could not have built such a city.
In and out among the caves, on the level floor of the main cavern, people were going about what seemed daily tasks. Men were talking together and mending weapons, some were fishing from the river; women were replenishing fires, preparing garments; and altogether it might have been any other village in Britain, to judge from their occupations. But it all struck Cororuc as extremely unreal; the strange place, the small, silent people, going about their tasks, the river flowing silently through it all.
Then they became aware of the prisoner and flocked about him. There was none of the shouting, abuse and indignities, such as savages usually heap on their captives, as the small men drew about Cororuc, silently eyeing him with malevolent, wolfish stares. The warrior shuddered, in spite of himself.
But his captors pushed through the throng, driving the Briton before them. Close to the bank of the river, they stopped and drew away from around him.
Two great fires leaped and flickered in front of him and there was something between them. He focused his gaze and presently made out the object. A high stone seat, like a throne; and in it seated an aged man, with a long white beard, silent, motionless, but with black eyes that gleamed like a wolf's.
