There is nothing remarkable about this star. It is simply the nearest one to this binary system, a handful of light-years away. But this star has now become a marker, the leading wave of something that cannot be stopped. She was there when they evacuated that system, thirty years ago.
The butterflies perform another trick of computation. The view zooms in, concentrating on that one star. The star becomes brighter, until it begins to show colour. Not white now, not even blue-white, but the unmistakable tint of green.
It isn’t right.

Ararat, p Eridani A System, 2675Scorpio kept an eye on Vasko as the young man swam to shore. All the way in he had thought about drowning, what it would feel like to slide down through unlit fathoms. They said that if you had to die, if you had no choice in the matter, then drowning was not the worst way to go. He wondered how anyone could be sure of this, and whether it applied to pigs.
He was still thinking about it when the boat came to a sliding halt, the electric outboard racing until he killed it.
Scorpio poked a stick overboard, judging the water to be no more than half a metre deep. He had hoped to locate one of the channels that allowed a closer approach to the island, but this would have to do. Even if he had not agreed to a place of rendezvous with Vasko, there was no time to push back out to sea and curl around hunting for something he had enough trouble finding when the sea was clear and the sky completely empty of clouds.
