After her shakedown cruise, Streaker stopped at the small human-dolphin colony of Calafia to pick up a few of the best graduates of its tiny academy. It was to be Toshio's first, and possibly last, visit to old Earth.

"Old Earth" was still home to ninety percent of humanity, not to mention the other terrestrial sapient races. Galactic tourists still thronged in to gawk at the home of the enfants terribles who had caused such a stir in a few brief centuries. They were open in their wagering over how long Mankind would survive without the protection of a patron.

All species had patrons, of course. Nobody reached spacefaring intelligence without the intervention of another spacefaring race. Had not men done this for chimps and dolphins? All the way back to the time of the Progenitors, the mythical first race, every species that spoke and flew spaceships had been raised up by a predecessor. No species still survived from that distant era, but the civilization the Progenitors established, with its all-encompassing Library, went on.

Of the fate of the Progenitors themselves there were many legends and even violently contradicting religions.

Toshio wondered, as just about everyone had for three hundred years, what the patrons of Man might have been like. If they ever existed. Might they even be one of the species of fanatics that had ambushed the unsuspecting Streaker, and even now sought her out like hounds after a fox?

It wasn't a pleasant line of thought, considering what the Streaker had discovered.

The Terragens Council sent her out to join a scattered fleet of exploration vessels, checking the veracity of the Library. So far only a few minor gaps had been found in its thoroughness. Here a star misplaced. There a species miscatalogued. It was like finding that someone had written a list describing every grain of sand on a beach. You could never check the complete list in a thousand lifetimes of a race, but you could take a random sampling.
