The idea was not so much virtual reality, but augmented reality. I’ve been really intrigued by adding a pair of goggles that overlay digital data over existing objects in the real world (virtual reality inside out, so to speak). You can see the effect using the app AcrossAir for the iPhone. What is more interesting to me is what we’ll do when we gamify augmented reality.

Just about my favorite turning point in history regards Henry VII and his sons, and the fact that the one who would become Henry VIII was the second son, and not originally meant to become king. How different would it all have turned out, with King Arthur instead of King Henry VIII?

I’ve long been interested in the topic of human biochemistry and personal responsibility, not least because of the many dumb things that I’ve done under the influence of adrenaline. We like to believe we’re rational decision makers, but rationality depends on a delicate biochemical balance that fails when we need it most. The fight-or-flight response enables some amazing physical feats, but it also largely shuts down the brain, so you act on instinct.

For a few years, I had been thinking that I wasn’t living up to the full potential of fantasy in my fantasy stories, as far as how far I was willing to push the speculative elements. In science fiction, you have an obligation to reality and believability, but in fantasy, what “reality” means is much more flexible.

Why did I pick Venus? The story is about love, and Venus is the planet of love. I’m not sure why I made it the old, wet Venus of pulp science fiction. But I grew up with that Venus, and I liked it.

I’m an innate pessimist, and tend to think that most noble goals can only remain so in principle: carnage and misery form a very large part of how things come to fruition—not only in the maintaining of empires, but also for things that might seem noble, like self-defence or even the attainment of freedom and equality.

I was writing a guest post about female costuming for the blog Heroines of Fantasy when I hit a long-buried nerve in my psyche about Leia and that gold bikini. I remember seeing the overhead poster in the movie theater and being so disappointed that Carrie Fisher had been put on seductive display for Return of the Jedi while all the men were depicted as action heroes.

When I was imagining this world, I really liked the idea of an invading alien force that was technologically superior to us, but had made numerous vital mistakes about the terrain and their enemy along the way. That—like, really, all wars—the war they waged had grown long and complicated, with infinite loose ends that never seem to quite wrap up.

Beauty, terror, and the sublime are also a huge part of the appeal of fallen angels, from Milton to Doré. Pandemonium had to combine the richness and luxury of the Aesthetic movement with the brimstone and gore and decay of Hell.

Who knows what aliens would do? They are alien. However, if they happened to conquer Paris anyway, I can see invaders studying artwork to learn more, just as archeologists now certainly study the art of any culture they are hoping to decipher.
