"Operator! Send recall torpedoes instantly to every outlying vessel!" He scuttled over to one of the private-band speakers. "X-794-PW! Radio general call for all vessels above E blank E to concentrate on battle stations! Throw out full-power defensive screens, and send the full series of detector screens out to the limit! Guards and patrols on invasion plan XB-218!"

"The immediate steps are taken, gentlemen!" He turned to the Council, his rage unabated. "Never before have we supermen of the Fenachrone been so insulted and so belittled! That upstart Overlord will regret that warning to the instant of his death, which shall be exquisitely postponed. All you of the Council know your duties in such a time as this—you are excused to perform them. General Fenimol, you will stay with me—we shall consider together such other details as require attention."

After the others had left the room Fenor turned to the general.

"Have you any immediate suggestions?"

"I would suggest sending at once for Ravindau, the Chief of the Laboratories of Science. He certainly heard the warning, and may be able to cast some light upon how it could have been sent, and from what point it came."

The Emperor spoke into another sender, and soon the scientist entered, carrying in his hand a small instrument upon which a blue light blazed.

"Do not talk here, there is grave danger of being overheard by that self-styled Overlord," he directed tersely, and led the way into a ray-proof compartment of his private laboratory, several floors below.

"It may interest you to know that you have sealed the doom of our planet and of all the Fenachrone upon it," Ravindau spoke savagely.

"Dare you speak thus to me, your sovereign?" roared Fenor.

"I dare so," replied the other, coldly. "When all the civilization of a planet has been given to destruction by the unreasoning stupidity and insatiable rapacity of its royalty, allegiance to such royalty is at an end. SIT DOWN!" he thundered as Fenor sprang to his feet. "You are no longer in your throne-room, surrounded by servile guards and by automatic rays. You are in MY laboratory, and by a movement of my finger I can hurl you into eternity!"
