no direct effect on humanity - or is so primitive that I'm unaware of it. Either way, I can't retrace my own steps."
Stymied again, Nafai didn't take his hand away. It might be too disturbing to the others, to keep touching the Index and then removing his hand.
Disturbing? No. He simply didn't want the embarrassment of having them know that again his would-be contribution was futile.
He was still sleepy. Luet's dream had woken him too early, and sitting here now, with nothing to do, he began to doze. He laid his head down on the table, resting on his other arm; still his fingers touched the Index.
He went back to that image of himself seen from above, a map being traced behind him as he hunted in circles through the woods. Maybe I really do that, he thought, drifting on the edge of sleep. Maybe I really move in circles.
"No you don't," said the Index. "Except when the animal you're tracking moved that way."
I might, said Nafai silently. I might drift around and around in large circles, casting for the tracks of some beast, never realizing that I'm seeing my own tracks. Maybe sometimes I hunt myself. Maybe I find my own tracks and think, what an exceptionally large beast, this will feed us for a week, and then I track myself and track myself and never catch up until one day I come upon my own body, lying there exhausted and starving, dying so that in my madness I now imagine myself detached from my body and...
I was dozing, he said silently.
"Here's the map of all your journeys," said the Index. "You'll see that you never make circles, except when tracking a beast."
Nafai saw in his mind a clear map of the land all around Dostatok, clear up to the mountains and beyond, showing all his journeys.
I've really covered this territory, haven't I, said Nafai silently.
But even as he said it, he saw it wasn't true. There was an area where none of his hunts had ever taken him. A sort of wedge right up among the mountains, tending toward the desert side of them, where none of his paths went.
Do you have a map of the others' hunting trips? asked Nafai.
Almost at once, a map that he "knew" was Elemak's hunts was superimposed on his own, and then a map of Vas's and Obring's hunts, and the group hunts. They interlocked until they formed a tight net all around Dostatok.
Except for that wedge in the mountains.
What's in that place in the mountains, where none of our paths meet?
"What are you talking about?" asked the Index.
The gap in the maps. The place where no one has been.
"There is no gap," said the Index.
Nafai focused on the spot, giving it all its attention. There! he shouted inside his mind.
"You speak to me as if you were pointing, and I can see you giving great attention to something, yet there is no point on the map that you're singling out above any other."
Could there be something here that is hidden even from yourself?
"Nothing on Harmony is hidden from me."
Why did you bring us to Dostatok?
"Because I've prepared this place for you to wait until I'm ready."
Ready for what?
"For you to carry me on the voyage to Earth."
And why should we have come here to wait?
"Because this is the nearest place where you could sustain your lives until I'm ready."
The nearest place to what?
"To yourselves. To where you are."
This was getting circular again, Nafai could see. He tried a different tack. When will you be ready for us to carry you to Earth? Nafai asked.
"When I call you forth," said the Index.
Call us forth from where, to where?
"From Dostatok," said the Index.
To where?
"To Earth," said the Index.
To Nafai it was clear - the empty place on the map, which the Index could not see, was also the place where they would gather to leave for Earth - again, a place that the Index could not name.
"I can name any place on Harmony," said the Index. "I can report to you any name that any human has ever given to any spot on this planet."
Then tell me the name of this place? asked Nafai, again focusing on the gap in the hunting maps.
"Point to a place and I'll tell you."
On a whim, Nafai mentally drew a circle all around the gap in the paths.
"Vusadka," said the Index.
Vusadka, thought Nafai. An ancient-sounding name. But not dissimilar to the word for a single step just
