Pastwatch- The Redemption Of Christopher Columbus - By Orson Scott Card Page 0,5

last of the obstacles was past now, surely. Ten days' sailing and he would step ashore in Cathay or India, the Spice Islands or in Cipangu. Nothing could stop him now, for God was with him, as he had been with him since that day on the beach when God appeared to him and told him to forget his dreams of a crusade. "I have a greater work for you," God said then, and now Columbus was near the culmination of that work. It filled him like wine, it filled him like light, it filled him like the wind in the sails over his head.
Chapter 2 Slaves
Though Tagiri did not put her own body back in time, it is still true to say that she was the one who stranded Christopher Columbus on the island of Hispaniola and changed the face of history forever. Though she was born seven centuries after Columbus's voyage and never left her birth continent of Africa, she found a way to reach back and sabotage the European conquest of America. It was not an act of malice. Some said that it was like correcting a painful hernia in a brain-damaged child: In the end, the child would still be severely limited, but it would not suffer as much along the way. But Tagiri saw it differently.

"History is not prelude," she said once. "We don't justify the suffering of people in the past because everything turned out well enough by the time we came along. Their suffering counts just as much as our peace and happiness. We look out of our golden windows and feel pity for the scenes of blood and blades, of plagues and famines that are played out in the surrounding country. When we believed that we could not go back in time and make changes, then we could be excused for shedding a tear for them and then going on about our happy lives. But once we know that it is in our power to help them, then, if we turn away and let their suffering go on, it is no golden age we live in, and we poison our own happiness. Good people do not let others suffer needlessly." What she asked was a hard thing, but some agreed with her. Not all, but in the end, enough.

Nothing in her parentage, her upbringing, or her education gave any hint that one day, by unmaking one world, she would create another. Like most young people who joined Pastwatch, Tagiri's first use of the Tempoview machine was to trace her own family back, generation before generation. She was vaguely aware that, as a novice, she would be observed during her first year. But hadn't they told her that as she learned to control and fine-tune the machine ("it's an art, not a science") she could explore anything she wanted? It wouldn't have bothered her, anyway, to know that her superiors nodded knowingly when it became clear that she was following her matrilineal line back to a Dongotona village on the banks of the Koss River. Though she was as racially mixed as anyone else in the world these days, she had picked the one lineage that mattered most to her, the one from which she derived her identity. Dongotona was the name of her tribe and of the mountainous country where they lived, and the village of Ikoto was her foremothers' ancient home.

It was hard to learn to use the Tempoview. Even though it had extraordinarily good computer-assisted guidance, so that getting to the exact place and time you wanted was precise within minutes, there was no computer yet that could overcome what the pastwatchers called the "significance problem." Tagiri would pick a vantage point in the village -- near the main path winding among the housesand then set up a time frame, such as a week. The computer would then scan for human passage and record all that took place within range of the vantage point.

All this took only minutes -- and enormous amounts of electricity, but this was the dawn of the twenty-third century, and solar energy was cheap. What ate up Tagiri's first weeks was sorting through the empty conversations, the meaningless events. Not that they seemed empty or meaningless at first. When she started, Tagiri could listen to any conversation and be enthralled. These were real people, from her own past! Some of them were bound to be ancestors of hers, and sooner or later she'd sort out which
