 Why did Yuri go back to Cupia?
6 Twelve months ago he would have been available, for he was then quietly visiting at my farm, after five earth-years spent on the planet Venus, where, by the aid of radio, he had led the Cupians to victory over their oppressors, a human-brained race of gigantic black ants. He had driven the last ant from the face of continental Poros, and had won and wed the Princess Lilla, who had borne him a son to occupy the throne of Cupia. II TOO MUCH STATIC Myles Cabot had returned to the earth to study the latest developments of modern terrestrial science for the benefit of the Cupian nation. He was the regent of Cupia during the minority of his baby son, King Kew the Thirteenth. The last of the ant-men and their ally, the renegade Cupian Prince Yuri, had presumably perished in an attempt to escape by flying through the steam-clouds which completely hem in continental Poros. But when he had finally and fully recovered, he found himself lying on a sandy beach beside a calm and placid lake beneath a silver sky. Could it be that all his adventures in Cupia had been naught but a dream; a recurring dream, in fact? The other three ants kept away from him as Doggo led him to the beached airplane, and soon they were scudding along beneath silver skies, northward as it later turned out. This was Cupia, his Cupia. He was home once more, back again upon the planet which held all that was dear to him in two worlds. What mattered it that he was now a prisoner, in the hands (or, rather, claws) of his old enemies, the Formians? He wondered what could have happened in Cupia since his departure, only a few sangths ago. In either event, how had they been able to reconquer Cupia? And where was their former leader, Yuri, the renegade Cupian prince? These and a hundred other similar questions flooded in upon the earth-man, as the Formian airship carried him, a captive, through the skies. What uninhabited portion of Cupia could this be, over which they were now passing? Apparently a few survivors of the accursed race of Formians were consolidating their position and attempting to build up a new empire in some out-of-the-way portion of the continent. It was in just such a garden, through just such a window, that he had first looked upon the lovely blue-eyed, golden-haired Lilla, Crown Princess of Cupia.
