"The choice, for Karhide, is yours, sir."

"And if I send you packing, too?"

"Why, I'll go. I might try again, with another generation…"

That hit him. He snapped, "Are you immortal?"

"No, not at all, sir. But the time-jumps have their uses. If I left Gethen now for the nearest world, Ollul, I'd spend seventeen years of planetary time getting there. Timejumping is a function of traveling nearly as fast as light. If I simply turned around and came back, my few hours spent on the ship would, here, amount to thirty-four years; and I could start all over." But the idea of timejumping, which with its false hint of immortality had fascinated everyone who listened to me, from the Horden Island fisherman on up to the Prime Minister, left him cold. He said in his shrill harsh voice, "What's that?"—pointing to the ansible.

"The ansible communicator, sir."

"A radio?"

"It doesn't involve radio waves, or any form of energy. The principle it works on, the constant of simultaneity, is analogous in some ways to gravity—" I had forgotten again that I wasn't talking to Estraven, who had read every report on me and who listened intently and intelligently to all my explanations, but instead to a bored king. "What it does, sir, is produce a message at any two points simultaneously. Anywhere. One point has to be fixed, on a planet of a certain mass, but the other end is portable. That's this end. I've set the coordinates for the Prime World, Hain. A NAFAL ship takes 67 years to go between Gethen and Hain, but if I write a message on that keyboard it will be received on Hain at the same moment as I write it. Is there any communication you'd care to make with the Stabiles on Hain, sir?"
