So light, so fleeting, and so unorthodox had been Nadreck's touch that the personnel of the now doomed base could not have known with any certainty that any visitor had actually been there. If there had been, the logical supposition would have been that he and his vessel had been resolved into their component atoms. Nevertheless Nadreck waited—as has been shown, he was good at waiting—until the burst of extra vigilance set up by the occurrence would have subsided into ordinary watchfulness. Then he began to act.
At first this action was in ultra-slow motion. One millimeter per hour his drill advanced. Drill was synchronized precisely with screen, and so guarded as to give an alarm at a level of interference far below that necessary to energize any probable detector at the generators of the screen being attacked.
Through defense after defense Nadreck made his cautious, indetectable way into the dome. It was a small base, as such things go; manned, as expected, by escapees from Onlo. Scum, too, for the most part; creatures of even baser and more violent passions than those upon whom he had worked in Kandron's Onlonian stronghold. To keep those intractable entities in line during their brutally long tours of duty, a psychological therapist had been given authority second only to that of the Base Commander. That knowledge, and the fact that there was only one populated dome, made the Palainian come as close to grinning as one of his unsmiling race can.
The psychologist wore a multiplex thought-screen, of course, as did everyone else; but that did not bother Nadreck. Kinnison had opened such screens many times; not only by means of his own hands, but also at various times by the use of a dog's jaws, a spider's legs and mandibles, and even a worm's sinuous body. Wherefore, through the agency of a quasi-fourth-dimensional life-form literally indescribable to three-dimensional man, Nadreck's ego was soon comfortably ensconced in the mind of the Onlonian.
That entity knew in detail every weakness of each of his personnel. It was his duty to watch those weaknesses, to keep them down, to condition each of his wards in such fashion that friction and strife would be minimized. Now, however, he proceeded to do exactly the opposite. One hated another. That hate became a searing obsession, requiring the concentration of every effort upon ways and means of destroying its object. One feared another. That fear ate in, searing as it went, destroying every normality of outlook and of reason. Many were jealous of their superiors. This emotion, requiring as it does nothing except its own substance upon which to feed, became a fantastically-spreading, caustically corrosive blight.
To name each ugly, noisome passion or trait resident in that dome is to call the complete roster of the vile; and calmly, mercilessly, unmovedly, ultra-efficiently, Nadreck worked upon them all. As though he were playing a Satanic organ he touched a nerve here, a synapse there, a channel somewhere else, bringing the whole group, with the lone exception of the commander, simultaneously to the point of explosion. Nor was any sign of this perfect work evident externally; for everyone there, having lived so long under the iron code of Boskonia, knew exactly the consequences of any infraction of that code.
The moment came when passion overmastered sense. One of the monsters stumbled, jostling another. That nudge became, in its recipient's seething mind, a lethal attack by his bitterest enemy. A forbidden projector flamed viciously—the offended one was sating his lust so insensately that he scarcely noticed the bolt that in turn rived away his own life. Detonated by this incident, the personnel of the Base exploded as one. Blasters raved briefly; knives and swords bit and slashed; improvised bludgeons crashed against pre-selected targets; hard-taloned appendages gouged and tore. And Nadreck, who had long since withdrawn from the mind of the psychologist, timed with a stop watch the duration of the whole grizzly affair, from the instant of the first stumble to the death of the last Onlonian outside the Commander's locked and armored sanctum. Ninety-eight and three tenths seconds. Good—a nice job.
The Base Commander, as soon as it was safe to do so, rushed out of his guarded room to investigate. Amazed, disgruntled, dismayed by the to him completely inexplicable phenomenon he had just witnessed, he fell an easy prey to the Palainian Lensman. Nadreck invaded his mind and explored it, channel by channel; finding—not entirely unexpectedly—that this Number One knew nothing whatever of interest.
