The intelligent planets were three: our own Diskra, of course, fourth from the sun. And nearest the sun, Mirla, that fiery globe, where life apes the quality of our own salamander, existing by necessity near the flames. And second from the sun Venia, the cloud-capped world, where life exalts the virtues of the fish. Of the third planet, Terra, we then knew little.

Our cities faced the sun in those days, towering in polychromatic splendor. Height was no obstacle then, for we had wings—wings! Think of it, O Beneficence! No need had we of clumsy, metal vessels. But all that has changed. Now no whirr of wings disturbs the air, and our formi-tectural splendors rise within. The history of this change is what Your Supreme Exaltation would know. This, then, is the record.

With the rule of Palladin was born the age of science, not so much due to the intellects of that day, as through the driving urge of ultimate necessity. For Palladin had a brother, Thid. He was unfortunately a mutant. Whereas our features were delicate and quite regular, Thid's were gross and stamped with power. His royal head was too large and cumbersome, and instead of our slender waists, he was almost asymmetrical in shape. In short—no member of our fairer, royal sex could look upon him with aught but horror. And it was because of this that he was dietetically conditioned for the realm of science.

It was a mistake. As the years passed, the loneliness of his virtual exile tended to derange Thid's prodigious mind! Aye, prodigious—and dangerous in his manic-depressive state. Then one day Palladin called an emergency meeting of the Inner Council. I, Braanol, was a member of that Council.

"It has come to my attention," Palladin said, "that Thid has been carrying on certain dangerous experiments! Experiments of a sort that could well be inimical to us—to our very existence!"

We well knew to what Palladin referred. But Thid was his brother, one of the Imperial ones. No one dared speak.

"Why was I not made aware of it sooner?" Palladin demanded sternly. "You, Braanol! You knew of it?"

"Yes, your majesty." I was frightened. "I beg to explain—I have tried to dissuade him—"

Palladin's visage became less stern, as though he understood our reluctance in this matter. "True," he said. "Thid is my brother. He must be mad! And I tell you now: if he has gone as far in this experiment as I suspect, I shall not hesitate to apply the only remedy dictated by efficiency—death! Have him brought to me at once."

But Thid was nowhere to be found. He had learned of Palladin's anger, and had fled into the Diskran desert where the abhorred Termans dwelt in myriads despite all our effort to eradicate them. These Termans were soft-bodied, subterranean creatures with an obstinate life-force, and we had long realized that they might one day be a menace to us.
