 Why did Yuri go back to Cupia?
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. 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. Could it be that all his adventures in Cupia had been naught but a dream; a recurring dream, in fact? He wondered what could have happened in Cupia since his departure, only a few sangths ago. And where was their former leader, Yuri, the renegade Cupian prince? What uninhabited portion of Cupia could this be, over which they were now passing?
