Redemption Ark

It was not simply about the war against intelligence, she told Clavain. That was only part of it; only one detail in their vast, faltering program of cosmic stewardship. Despite all evidence to the contrary the wolves were not trying to rid the galaxy of intelligence altogether. What they were striving to do was akin to pruning a forest back to a few saplings rather than incinerating or defoliating completely; or reducing a fire to a few carefully managed flickering flames rather than extinguishing it utterly.

Think about it, Felka told him. The existence of the wolves solved one cosmic riddle: the killing machines explained why it was that humanity found itself largely alone in the universe; why the Galaxy appeared barren of other intelligent cultures. It might have been that humanity was just a statistical quirk in an otherwise lifeless cosmos; that the emergence of intelligent, tool-using life was astonishingly rare and that the universe had to be a certain number of billion years old before there was a chance of such a culture arising. This possibility had lingered on until the dawn of the starfaring era, when human explorers began to pick through the ruins of other cultures around nearby stars. Far from being rare, it looked as if tool-using technological life was actually rather common. But for some reason, these cultures had all become extinct.

The evidence suggested that the extinction events happened on a short timescale compared with the evolutionary development cycles of species: perhaps no more than a few centuries. The extinctions also seemed to happen at around the time each culture attempted to make a serious expansion into interstellar space.

In other words, at around the development point that humanity — fractured, squabbling, but still essentially one species — now found itself.

Given that premise, she said, it was not too surprising to find that something like the wolves — or the Inhibitors, as some of their victims called them — existed; they were almost inevitable given the pattern of extinctions: remorseless droves of killer machines lurking between the stars, waiting patiently across the aeons for the signs of emergent intelligence …
