Sure that they would win in this race now, since he was just beginning to realize the vastness of his power--the all-encompassing, all-mastering power of the human mind and will, which the white flames of the Moon had made almost god-like--Sarka turned his eyes toward a coldly gleaming sphere in the star-spangled heavens ahead. * * * * * It was the Earth, and it seemed ringed in flames! From its edges there seemed to shoot long streamers of yellow or golden flames, which broke into sunlike pinwheels of radiance at their tips. Something, there on the precious Earth, was decidedly wrong! Instantly, telepathically, he sought to gain mental contact with his father. "Father, we are coming!" he said, across those countless miles. "What is happening?" For a full minute there was no answer. Then it came, feeble, broken, weighted with fear; but it was a thought-message, unmistakably, of Sarka the Second. "Hurry, son! Hurry! For Dalis has indeed betrayed us! I could not maintain control of the Earth with the Beryls, for some strange catastrophe has destroyed all the Beryls in the area Dalis ruled! The shifting of positions of the Earth and the Moon has so altered the relative effects of the pull of gravity exerted by the planets that Mars has been brought into dangerous proximity to us and is already so close that her ether-lights are playing over us!

Cold fear clutched at the throat of Sarka as he caught the message. He decided not to tell Jaska for the moment. He looked to right and left, at the aircars on either side of him, then issued his commands. "Faster! Faster! Be prepared to land in the area of the Gens of Cleric, as close as possible to my laboratory!" A strange, awesome sight, that flight of the rebels of Dalis' Gens from the Moon to the Earth--like gleaming stars across the void.
