And, advancing under the crest of that lick of destruction, came its controller. This was no ghost drawn from the materials of the swamp; this was a man, walking quietly, his hands as empty as Tau's, yet grasping weapons none of them could see. In the firelight, as the wave receded sullenly, men moaned, lay face down upon the ground, beat their hands feebly against the earth. But, as Lumbrilo came on from the shadows, one of them got to his hands and knees, moving with small tortured jerks. He crawled toward Tau, his head lolling on his shoulders as the head of the dead rock ape had done. Dane patted the drum with one hand while, with the other, he groped for his fire ray. He tried to shout in warning and found that he could not utter a sound. Tau's arm moved, raised from his side, made a circling motion. The creeping man, his eyes rolled up in his head until only the whites gleamed blindly in the limited light, followed that gesture. He drew level with the medic, passed beyond toward Lumbrilo, whining as a hound prevented from obeying his master might lament. "So be it, Lumbrilo," Tau said. "This is between you and me. Or do you not dare to risk your power against mine? Is Lumbrilo so weak a one that he must send another to do his will?" Raising both hands again the medic brought them down, curling inward, until he stooped and touched them to the ground. When he straightened once again the knife was in his grasp and he tossed it behind him. The smoke from the fire swirled out in a long tongue, coiled about Lumbrilo and was gone. A black and white beast stood where the man had been, its tufted tail lashing, its muzzle a mask of snarling hate and blood lust. But Tau met that transformation with laughter which was like the lash of a whip. "We both be men, you and I, Lumbrilo. Meet me as a man and keep those trickeries for those who have not the clear sight. A child plays as a child, so--" Tau's voice came in a rumble, but Tau was gone. The huge, hairy thing which swayed in his place turned a gorilla's beast visage to his enemy. For a breathless moment Terran ape confronted Khatkan lion. Then the spaceman was himself again. "The time for games is over, man of Khatka. You have tried to hunt us to our deaths, have you not? Therefore death shall be the portion of the loser now." Lion vanished, man stood watching, alertly, as swordsman might face swordsman with a blood feud lying on their blades. To Dane's eyes the Khatkan made no move. Yet the fire leaped high, as if freshly fed, and flames burst from the wood, flew into the air, red and perilous birds, darting at Tau until they outlined him from the ground under his boots to an arch over his head. They united and spun faster until Dane, watching with dazzled eyes, saw the wheel become a blur of light, hiding Tau within its fiery core. His own wrists ached with the strain of his drumming as he lifted one hand and tried to shield his sight from the glare of that pillar of fire.
