"None, as you understand the term. We travel by instantaneous translation, by means of something we call 'Gunther'.... I am not at all sure that I can explain it to you satisfactorily, but I will try to do so, if you wish."
"Please do so, sir, by all means."
Garlock opened the highest Gunther cells of his mind. There was nothing as elementary as telepathy, teleportation, telekinesis, or the like; it was the pure, raw Gunther of the Gunther Drive, which even he himself made no pretense of understanding fully. He opened those cells and pushed that knowledge at the two Hodellian minds.
The result was just as instantaneous and just as catastrophic as Garlock had expected. Both blocks went up almost instantly.
"Oh, no!" Atterlin exclaimed, his face turning white.
The girl shrieked once, covered her face with her hands, and collapsed on the floor.
"Oh, I'm so sorry ... excuse my ignorance, please!" Garlock implored, as he picked the girl up, carried her across the room to a sofa, and assured himself that she had not been really hurt. She recovered quickly. "I'm very sorry, Grand Lady Neldine and Governor Atterlin, but I didn't know ... that is, I didn't realize...."
"You are trying to break it gently." Atterlin was both shocked and despondent. "This being the first planet you have visited, you simply did not realize how feeble our minds really are."
"Oh, not at all, really, sir and lady." Garlock began deftly to repair the morale he had shattered. "Merely younger. With your system of genetics, so much more logical and efficient than our strict monogamy, your race will undoubtedly make more progress in a few centuries than we made in many millennia. And in a few centuries more you will pass us—will master this only partially-known Gunther Drive.
