Into one of the tall white-and-gold palaces of the Lords of Gral-Thala they were taken, and down into stone-walled dungeons far underground. They were placed in a single cell. They stood with their backs against the walls, arms out-stretched and wrists lashed to rings set in the stone, able to move little more but their heads. Then, for a while, they were left alone. "Well," said Larry with grim humor, "here we are." "So it seems!" Pyatt's voice was rasping and bitter. "I am indeed a fool for ever having allowed Xylon to live in the Cavern of Chotan, in spite of the kind-hearted ruling of the Elders." "What will they do with us?" Larry asked. Pyatt hesitated, licking his lips and glancing at Diana, but the girl answered for herself. "We shall probably be skinned alive in the public square, dying slowly under the torture," she said. "It is the favorite punishment of the tyrants for those they particularly hate." It was a day of triumph for the Lords of Gral-Thala. Xylon's triumphant return with the information that would lead to the wiping out of the always troublesome outlaws of the Lost Caverns, and the capture of the three prisoners, made it a holiday for the ruling class of the valley. They came in hundreds to see the three captives. The famous military leader of the outlaws ... the girl who was considered a goddess by the primitive Insect-men of the waste-land ... the the stranger from that distant Earth whence their own ancestors had fled. They came to throng the dungeon corridor and stare in at the trio of captives spread-eagled against the wall of the cell. Larry watched them through the barred door. For hours on end there were always a few of them in the corridor, staring and jeering. Foppish men in white and gold with their curled hair laden with scent. Haughty and jewel-clad women whose sharp featured faces held even more cruelty than their male companions. Many were attended by Lunarian slave girls whose fettered hands held their trains up from the floor, and the bare backs of the slave girls were usually marked with the crossing red marks of whips. Larry knew, now, that the tales told in the Caverns about the cruelty of the Lords of Gral-Thala had not been exaggerated. * * * * * Xylon came to see them after a while, opening the cell door and walking in to stand sneering at them with his thumbs hooked in his jeweled girdle. "Colton sold you out for the promise of wealth and a place in the ranks of our nobles," he said. "It will be a pleasure to watch you die." For a moment he walked over to stand in front of Diana who looked back at him with an expressionless face. "You are not a bad-looking wench. I can take you for one of my slaves if you wish to be agreeable." "I would rather go with an Insect-man!" the girl said with calm scorn. Xylon shrugged and turned away. "So be it. At that, it would be a pity to rob the crowd of the pleasure of watching you die."
