And it revealed more. For Dworn saw by that unholy light that one of the nearer beetles--capsized and burned out, its carapace burst raggedly open--it bore the golden scarab emblem which was the chief's alone. The sight smote Dworn like a physical blow, so that he almost cried out aloud. Somehow it had not even crossed his mind that his father Yold could have been among the slain in whatever disaster had fallen upon the beetles here.... Others might die; but his father was a pillar of strength that could not fall--the grave iron-willed chief, demanding and rewarding, for his son impartially as for all the people.... Dworn's breath choked in his throat and his eyes stung. Fiercely he told himself that a beetle, a chief's son, did not weep. Not to mourn--to revenge, that was his duty. By the law of his people, the bereaved son must seek out and slay not less than three members of whatever race had done his father to death. Until then, his father's insatiate spirit would roam the deserts without rest.... But Dworn did not even know as yet who had done this night's work. Suddenly, by the new blaze that still continued, he saw movement, a dull sheen of metal moving, and he froze the gesture that had been about to send him forward into the arena of death. The infrared was useless; by it the flickering firelight was blinding. Dworn bit his lip in anger at his own lack of precaution, and hastily twisted his sound-receptor control to maximum. The crackling of the flames swelled to a hissing roar, but through it he heard the unmistakable creaking sound of treads. Beyond the smoke moved an indistinct and monstrous shape. Dworn's jaw muscles set rock-hard and his hand flashed to another control. His turret gun revolved soundlessly, and the crosshairs of the sight danced across the mirrored image of the approaching thing. His finger poised over the firing button, he braced himself to fling his machine into swift evasive action before the enemy's perhaps overwhelming firepower could reply-- The monster lumbered slowly into the light, canted far over and traveling with an odd sidling motion along the steep rubbly slope. Great treads set far out on each side of the squat, ungainly body preserved it against overturning. Its flattened forward turret swiveled nervously from side to side, peering blackly from vision ports steel-shuttered down to squinting slits. And Dworn relaxed. The red hatred that had blazed up in him subsided into mere disgust; he watched the great machine's wary progress with a familiar, instinctive contempt. It was a scavenger, huge but not very formidable, drawn from afar by the fires which promised loot, salvageable scrap, perhaps even usable parts, fuel or ammunition.... It could not possibly have been responsible for the carnage; such cowardly creatures gave a wide berth to the beetle horde.
