As Hekki's jailer led him away, Shelby, assisted by Janice Darell, busied himself with the ship's controls.

And so the battered Selba escorted by five thousand Space Men set out for a certain minor planet where were amassed the forces of Telaba, insubordinate vassal of the Black Emperor. And on another planet was Alkebar, the Black Emperor himself, ready to hurl his shock troops, a horde five million strong, at the planets.


CHAPTER IX

The Revolt of Alkebar

The light of a shrunken sun shone down coldly and ineffectually upon a jagged and distorted landscape. Along the horizon, which was strangely abrupt, twisted gray hills loomed up with harsh clearness against a black starlit sky. There was no atmosphere to soften their lines, nor to dull the needle-like points of deepest sable that were their shadows.

In the foreground, which was a fairly level plain, were hundreds of hemispherical shelters hastily built from loose fragments of rock. A vast horde of Space Men hemmed them in. The sunlight glistened on the ebony hides of the warriors and on their polished accouterments and weapons. Some of these rebels of the void were greedily drinking the purple radio-active liquid which meant life and strength to them, and attendants were hurrying about carrying large canisters of the food to each unit of Telaba's army. Most of the men crouched expectantly beside their discs, waiting.

In a small metal building, which the Man from the Fourth World had recently had constructed for his own use, four people were gathered. Two were Space Men, and two belonged to the green planet called Earth. One of the Space Men was talking, not with his mouth for he had no vocal cords, but by means of fine mental vibrations which caused a feeble high-pitched voice to speak within the minds of the Earthians.

"I owe you great debt of gratitude, Mr. Shelbee—you help to save my son from Alkebar and Fourth World Man. Telaba do not forget this. I do what I can. But that is little. Black Emperor start to smash Earth and Mars soon. Perhaps right now. Perhaps in hour. Who know? Spy send signal any time now. We outnumbered ten to one. Alkebar crush us, wipe us out like that!" He slapped his palms sharply together. "But we do what we can, Earthman."

Shelby took Telaba's cold hand for a brief hearty handshake. "Thanks, Telaba," he said simply. "Jan and I certainly appreciate what you are going to do for us and our people, and I know that if we are successful, the worlds shall be mighty grateful too. They have ways of showing their gratitude. But don't be so sure that we are going to fail. We have the Selba, you know, and a new weapon that has never before been used.
