I knew I wanted to tackle a story that was hard SF, and set off Earth, so why not on one of Jupiter’s moons? I have a bad habit of starting story development with setting instead of plot, and that’s what happened here. So I just kept throwing ideas at the page until I had enough to create a story for my chosen setting.

If you’re looking at society at large, I think there would be a lot of civil unrest inspired by the destruction of our society’s existing certainties about the way the world works. I imagine millennial cults would develop and that traditional religious belief would see a sharp rise. Secular and scientific voices would likely be drowned out.

I really wanted to write about this world I’d discovered, its rich, slow secrecy—its winter melancholy that turned gradually, then all at once, into an astoundingly fecund summer. To do that, I needed a plausible way for Molly to stay behind, to live reasonably well in an otherwise-abandoned version of the place. I hit upon a creeping apocalypse.

A couple years ago when I was actively blogging, some editorial minion had complained about their slushpile being full of stories with titles that spoiled the ending mixed with time-travel stories about people trying to kill Hitler. I commented that maybe it wasn’t a good time to submit my story titled “The Cross-Time Accountants Fail to Kill Hitler Because Chuck Berry Does the Twist.”

I obediently spent my childhood writing little stories, until I reached that age when you dig in your heels and tell your parents you hate them and you’ll never, ever be what they want you to be. And I more or less ran away with the circus for the next twenty years.

The notion of basilisk images was something I’d had in mind ever since reading Douglas Hofstadter’s Gödel, Escher, Bach. Hofstadter’s favourite analogy for the impact of Gödel’s Theorem on mathematics is a music recording that can’t be played because its resonances destroy the playing mechanism.

The difficulty was in trying to make the time and place more real—all this happened more than a thousand years ago, and in a part of the world that we don’t usually learn much about. Set a story in Ancient Rome or 12th Century England, and the reader will most likely have a mental file of background information; medieval Kiev is pretty much a mystery.
