people they encountered could do no one any good, he had always done what he could to keep the damage
to a minimum. He had tried his best to keep the ship away from inhabited worlds entirely, since the
computer had picked up and understood enough to assume that no place outside the solar system remained
loyal to Old Earth after the D-series hit; humans, unlike computers, saw no point in remaining loyal to a
burnt-out ruin.
At least, rational humans who knew what had hap-pened, such as those who inhabited most colony
planets, had seen no point in such loyalty. On Dest, no one had had any idea what was going on, so the
ques-tion had never come up. Elsewhere, anyone who might still have possessed starships or any sort of
long-range telecommunications surely knew that nothing was left on Old Earth to fight for.
Someone, though, was out there now, calling, ". . . Anyone loyal to Old Earth, please respond . . ."
He thrust that thought aside for the moment as he continued reviewing what he knew.
The computer had, despite Slant's best efforts, forced him to land on a few inhabited planets, and one of
them, the last, had been Dest. The computer, hav-ing detected anomalies in the planet's gravitational field,
as if the natives here had invented antigravity, quite logically had interpreted this as enemy weapons
research.
Turner shook his head. Even now he could not un-derstand why the anomalies had shown up on the ship's
sensors as antigravity. The actual cause had been the psionic abilities known to the natives as "wizardry" or
"magic." These abilities had apparently originated as a chance mutation after an Old Earth fleet, for
rea-sons Turner could only guess at, had been sent out here and had bombed Dest back to barbarism; the
re-sulting radiation was still, centuries later, causing mu-tations, most of which were far less favorable. His
computer had had records of the fleet being sent, but no records of why it had been sent, and so far as
Turner knew, no one on Dest had even realized the fleet was human in origin. The ships had suddenly
ap-peared above them, and their cities had vanished, and knowing nothing of the rebellion against Old Earth,
most of them had naturally assumed the attackers to be hostile extraterrestrials. Some might have realized
what was happening, but when Slant had arrived in Praunce three hundred years after the attack, his
state-ment that Old Earth had sent the fleet had come as a shock to the wizards there.
The Bad Times had destroyed Dest's old civilization pretty thoroughly, and only the fabulous good luck
that wizardry had turned up in the aftermath had per-mitted the survivors to rebuild as well, and as quickly,
as they had. However the talent had originated, it could be passed on, and not merely to the mutants' direct
descendants—the psionic ability itself allowed one to telekinetically alter the neurons of the human brain so
as to induce psionic abilities in others. Of course, these psionically created wizards did not breed true, since
only the brain had been changed, and not the genes, but that was enough. In fact, the original mutant strain
had died out, yet wizardry had survived and spread quickly and had become a cornerstone of most postwar
societies on Dest.
Wizards could levitate, either themselves or others or anything else in sight that was not too heavy, but
Turner did not think it was actually antigravity that they used. For one thing, almost all wizardry, not just
levitation but anything that required much energy, had registered as gravitational anomalies, and he simply
didn't see how mind reading or the eerie psionic senses could involve antigravity. He had no idea what they
were, but they seemed more likely to be electromagnetic in nature than anything else. At close range, even
before he became a wizard himself, he had been able to sense when magic was in use because he felt a
sort of electric tingle, like static in the air, which seemed to indicate an electromagnetic nature. Ordinary
people felt no such sensation; it was his cyborg circuitry that registered it somehow. The computer had
been unable to detect or explain the tingling. It had only been able to discern the "gravitational anomalies."
Even now, when he knew exactly what changes were necessary to make a human brain capable of
wiz-ardry, he had no idea how the phenomenon worked, any more than a caveman could have explained a
radio after being taught to wire together the appropriate parts. He only knew that it worked.
His own theory of why wizardry registered as anti-gravity was that all psionic activity somehow created
some sort of interference that had affected the ship's most delicate and sensitive equipment, its gravity
sen-sors, without actually having any connection with grav-ity at all.
Even if they were not antigravity, however, the computer had found these mysterious talents quite
dangerous enough, and it had insisted that Slant learn how this "magic" operated so that the information
could be taken back to Old Earth. Once the secrets were known, as much as possible of the planet's
popu-lation was to be destroyed, to eliminate any future threat to Old Earth's well-being.
It had taken everything he could do, as well as the efforts of a good many wizards and the manipulation
of the computer's own desire for self-destruction, to shut down CCC-IRU 205 for good. He had
uninten-tionally brought down his ship in the process, wrecking it beyond hope of repair.
Once that was done, leaving him permanently stranded on this curious planet, he had accepted an
