"When they move," Tau's lips were beside his ear, "jump for that drum. I don't care how you get it, but get it and keep it!"
"Yes, sir!"
There was a wailing cry from the north, a howl of witless fear. The singers stopped in mid-note, the drummer paused, his hand uplifted. Dane darted forward in a plunge which carried him to that man. The Khatkan did not have time to rise from his knees as the barrel of the fire rod struck his head, sending him spinning. Then the drum was cradled in the spaceman's arm, close to his chest, his weapon aimed across it at the startled natives.
The crackle of blaster fire, the shrill whine of needlers in action, raised a bedlam from the other end of the camp. Backing up a little, Dane went down on one knee, his weapon ready to sweep over the bewildered natives, the drum resting on the earth against his body. Keeping the fire rod steady, his left hand went to work, not in the muted cadence the Khatkan drummer had chosen, but in hard and vigorous thumps which rolled across the clamor of the fight. There was no forgetting the beat of "Terra Bound" and he delivered it with force, so that the familiar da-dah-da-da droned loud enough to awaken the whole camp.
Dane's move appeared to completely baffle the Khatkan outlaws. They stared at him, the whites of their eyes doubly noticeable in their dark faces, their mouths a little agape. As usual the unexpected had driven them off guard. He dared not look away from that gathering to see how the fight at the other end of the camp was progressing. But he did see Tau's advance.
The medic came into the light of the fire, not with his ordinary loose-limbed spaceman's stride, but mincingly, with a dancing step, and he was singing to the drum beat of "Terra Bound." Dane could not understand the words, but he knew that they patterned in and out of the drum beats, weaving a net between singer and listeners as Lumbrilo had woven his net on the mountain terrace.
Tau had them! Had every one of the native outlaws ensnared, so that Dane rested his weapon across his knee and took up the lower beat with the fingers of his right hand as well.
Da-dah-da-da.... The innocuous repetitive refrain of the original song which had been repeating itself in his mind faded, and somehow he caught the menace in the new words Tau was mouthing.
Twice the medic shuffled about a circle of his own making. Then he stooped, took a hunting knife from the belt of the nearest Khatkan and held it point out toward the dark east. Dane would not have believed the medic knew the drill he now displayed, for with no opponent save the dancing firelight he fought a knife duel, feinting, striking, twisting, retreating, attacking, all in time to the beat of the drum Dane was no longer conscious of playing. And as he strove it was very easy to picture another fighting against him. So that when the knife came up in a vicious thrust which was the finish of his last attack, Dane stared stupidly at the ground, half expecting to see a body lying there.
Once more Tau ceremoniously saluted with his blade to the east. Then he laid it on the ground and stood astride its gleaming length.
"Lumbrilo!" His confident voice arose above the call of the drum. "Lumbrilo—I am waiting."

Vaguely aware that the clamor at the other end of the camp had died away, Dane muted the sound of his drum. Over its round top he could watch the Khatkan outlaws; their heads bobbed and swayed in time to the beat of his fingers. He, too, could feel the pull of Tau's voice. But what would come in answer? That shadowy thing which had been loosed to drive them here? Or the man himself?
To Dane, the ruddy light of the fire dimmed, yet there was no actual dying of those flames which coiled and thrust around the wood. And the acrid scent of burning was thick. How much of what followed was real, how much the product of his tense nerves, Dane was never afterwards able to tell. In fact, whether all the witnesses there saw the same sights could be questioned. Did each man, Khatkan and off-worlder, see only what his particular set of emotions and memories dictated?
Something swept in from the east, something which was not as tangible as the creature born of swamp mist. Rather it came as an unseen menace to the fire, and all that fire signifies to human kind—security, comradeship, a weapon against the age-old forces of the dangerous night. Was that threat, too, only in their minds? Or had Lumbrilo some power to so shape his hatred?
The unseen was cold; it sapped a man's strength, bit at his brain, weighted his hands and feet, weakened him. It strove to soften him into clay another could remold. Nothingness, darkness, all that was opposed to life and warmth and reality, arose in the night, gathered together against them.
Yet still Tau fronted that invisible wave, his head high. And between his sturdily planted feet the knife gleamed bright with a radiance of its own.
"Ahhh—" Tau's voice curled out, to pierce that creeping menace. Then he was singing again, the cadence of his unknown words rising a little above the pattern wrought by the drum.
Dane forced his heavy hands to continue the beat, his wrists to rise and fall in defiance of that which crept to eat their strength and make them less then men.
"Lumbrilo! I, Tau, of another star, another sky, another world, bid you come forth and range your power against mine!" Now there was a sharper note in that demand, the snap of an order.
He was answered by another wave of the black negation—stronger, rolling up to smash them down, as a wave in the heavy surf of a wild ocean pounds its force against the beach. This time Dane thought he could see that dark mass. He tore his eyes away before it took on substance, concentrating on the movements of his hands against the drum head, refusing to believe that hammer of power was rising to flatten them all. He had heard Tau describe such things in the past. But told in familiar quarters on board the Queen, such experiences were only stories. Here was danger unleashed. Yet the medic stood unbowed as the wave broke upon him in full.
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.
