Your Supreme Beneficence! When the imperial messengers came to me, bringing the communication with which you deigned to address my decrepit solitude, it was like a glorious ray of light come to illumine the deepening darkness of my declining years! It is with trepidation that I set about to fulfill your Exalted Command. Five millenniums, aye, even more, have passed, since those who were part of that segment of history into which you inquire, have become but drifting dust. Only within the feeble memory of your humblest servant is there any record of it. Five millenniums! Aye! That was truly the golden period of our beloved Diskra--not that our period under _Your_ Serene Effulgence is not golden indeed! But in that day all Diskra was under the glorious rule of Palladin. His city on the scarlet shores of our central sea was the wonder of us _all_. Aye! We had a sea then, where there is now but desert. 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.
