"You do not know?" asked Denham, in surprize. "I thought you would, by now. These men, these thousands of warriors in the city here around you, have been gathered here by the Raider to act as his armies, his mercenaries, to pour down in hordes upon the cities of the enemies of the Kanlars, and destroy those enemies utterly, which the Kanlars are too few in number to do."
I gasped with astonishment. Denham went on. "You tell him, Fabrius," he said, addressing the Roman. "You have been here longer than any of us."
The centurion spoke, in a slurred, accented English. "Some things I have heard," he said, "but whether true or not, I can not say. There was a man here I knew when first I was brought here, a Persian. Before he was killed (for he was killed in a drunken brawl) he told me that once, in the city above, one of the Kanlars had become drunk and had babbled to him the story of his race.
"As you know, endless fields of ice lie around this land where is the Kanlar's city. Well, the Persian said that these fields of ice were not endless, that far to the south there were other green lands and in them a mighty people and a mighty city, named Kom. He said that long ago the Kanlars lived in this city, and were of its people, but that trouble had risen between them and the other people of Kom, because of the Raider. More than this he did not know, but said that because of this trouble, the Kanlars had fled from the city, with the Raider leading them, and coming north in their air-boats over the ice-fields, had found this green, uninhabited land, set in the ice. Its existence had never been suspected by those in Kom, who thought that the ice extended clear north to the very edge of earth.
"So the Kanlars had settled here and had built the city of cylinders, which lies above us. But still they planned to sweep back on Kom, and annihilate all there. But this they could not do, being too few in number. So the Raider, who is their god and their king, spoke to them and said that he would bring them men from every age of earth's past to be their servants, to fight for them at will. The Raider could travel at will through time—ask me not how!—and he swept back through the centuries and brought men by the thousands to the Kanlars, young warriors to fight their battles for them.
"There was a great cavern far beneath the city of the Kanlars, a great hollow space formed by inside shiftings of the young earth, and in this the Kanlars prisoned the men brought by the Raider, piercing a shaft down to it from their temple above, and placing in that shaft the stairway down which you came, under the direction of the Raider. They chose from among their prisoners some to be guards of the others, and those killed in battle here they brought back to seeming life by their arts of hell, and used as slaves.
"So, steadily, the hordes here in the pit have grown in number, until scarcely more could be contained here. Soon there will be enough to suit the purpose of the Raider and then they will be loosed and hurled south to carry fire and death to the cities beyond the ice, to Kom and the people of Kom, who can have no knowledge whatever of the peril that hangs over them. Up on the great roof of the temple, which is the home of the Raider, there are scores of great flying-platforms which the Kanlars have been constructing. They have made strange weapons, too, and so when their hour strikes, they will open the gates here and allow the hordes to pour up the stair, up to the roof of the temple, where they will crowd into the flying-platforms, under the leadership of the Kanlars, and race south over the ice to rain down death and destruction on Kom. And thus will the Raider and the Kanlars be revenged upon the people who cast them out."
Fabrius stopped, and I looked at Lantin, then back toward the Roman. Was this the true secret of the Raider's activity?
"But will the hordes here do this?" I asked. "Will they follow the Kanlars, and obey them?"
