Arcot indicated to Torlos that he was to go with him. Wade and Fuller followed.

When they had all seated themselves, Arcot began the telepathic questioning. "Torlos, why did you force Morey to leave the ray and then destroy the city? You certainly had no reason to kill all the non-combatant women and children in that city, did you? And why, after I told you absolutely not to use the heat beam while we were invisible, did you use the rays on that battleship? You made our invisibility break down and destroyed a tube. Why did you do this?"

"I am sorry, man of Earth," replied Torlos. "I can only say that I did not fully understand the effect the rays would have. I did not know how long we would remain invisible; the thing has been accomplished in our laboratories, but only for fractions of a second, and I feared we might become visible soon. That was one of their latest battleships, equipped with a new, secret, and very deadly weapon. I do not know exactly what the weapon is, but I knew that ship could be deadly against us, and I wanted to make sure we were not attacked by it. That is why I used the beam while your ship was invisible.

"And I did not intend to destroy the city. I was only trying to tear up the factory that builds these battleships; I only wanted to destroy their machines. I had no conception of the power of that ray. I was as horrified to see the city disappear as you were; I only wanted to protect my people." Torlos smiled bitterly. "I have lived among these treacherous people for many years, and I cannot say that I had no provocation to destroy their city and everyone in it. But I had no intention of doing it, Earthman."

Arcot knew he was sincere. There could be no deception when communicating telepathically. He wished he had used it when communicating with the Commanding One of Sator; the trouble would have been stopped quickly!

"You still do not have any conception of the magnitude of the power of that beam, Torlos," Arcot told him. "With the rays of this ship, we tore a sun from its orbit and threw it into another. What you did to that city, we could do to the whole planet. Do not tamper with forces you do not understand, Torlos.

"There are forces on this ship that would make the energies of your greatest battleship seem weak and futile. We can race through space a billion times faster than the speed of light; we can tear apart and destroy the atoms of matter; we can rip apart the greatest of planets; we can turn the hurtling stars and send them where we want them; we can curve space as we please; we can put out the fires of a sun, if we wish.

"Torlos, respect the powers of this ship, and do not release its energies unknowingly; they are too great."

Torlos looked around him in awe. He had seen the engines—small, apparently futile things, compared with the solid might of the giant engines in his ship—but he had seen explosive charges that he knew would split any ship open from end to end bounce harmlessly from the smooth walls of this ship. He had seen it destroy the fleet of magnetic ships that had formed a supposedly impregnable guard around the mightiest city of Sator.

Then he himself had touched a button, and the giant city had shot off into space, leaving behind it only a screaming tornado and a vast chasm in the crust of the blasted planet.
