Without words, he realized: If I attach to this twenty-first path, then I will truly be cut off from the rest of the universe. But it’s what I came for. This is my purpose. This is my gamble in order to save Garden from the Destroyers.

What he felt was not fear—fear was an emotion tied to the body. He felt nothing, not in the usual sense. But he knew that attaching to that nub of backward-streaming path could mean utter failure or complete success.

He remembered that there were two of him, and he wondered what the other version of himself might do if he were here instead of Noxon. Rigg was the one who had seen the need to kill Ram Odin, and he had done it. Then Rigg was the one who saw the need not to have killed him, and so he undid it. But from this choice there would be no undoing.

Noxon could hesitate as long as he wanted. His body would not decay here. He could not die.

But neither could he live. Neither could he act and make changes in the world.

Of course, heading backward he couldn’t make changes outside the limits of this starship. It would be a very small world indeed. And who knew if, once caught in that timeflow, the regular stream of causality would not become as invisible as backward-flowing time had been to him till now.

Filled with uncertainty, filled with determination, Noxon mentally attached himself to that nub of a path, that path of a kind and color he had never seen before. He attached to it, and left that moment of nothingness.

The moment he could sense motion again—and it felt completely normal, he felt like himself, nothing had changed, and that infinite moment between everything was now infinitesimal in his memory—in that moment he began to slice time so that he would be invisible and undetectable to the computers.

He did not know if he had acted quickly enough. He did not know how long it would take the computers to be aware of the presence of the jewels he carried with him. Or how long it would take the computers to upload all the contents of the jewels, containing as they did the entire history of the human race in every wallfold of Garden. And the history of Ram Odin on all nineteen starships.

But even if it had absorbed every speck of those memories, it didn’t matter the way it would have if he had joined with any of the nineteen forward-moving copies of the ship. Because this ship was going back to Earth, but undetectably. As it now was, this ship could not have any effect on the rest of the universe.
