When I started my online magazine, Intergalactic Medicine Show, I hoped to promote it by including a new story set in the Ender's Game universe in every issue. That worked for a while -- as long as I could come up with stories I could be proud of. But after a while, I learned that I can't come up with stories on demand.
Then the launch of a comic book series led to the idea of doing an original story in the Ender's Game universe as an original comic book. For me, the comic book form requires that there be a much stronger visual component than in narrative fiction. So I began to think of ways to put humans in contact with Formic technology.
Only instead of having machine-based tech, I thought: What if the Formics did their mining by using specially bred animals? Abandoned machines rust and decay, but what do abandoned animals do? I had my visual, and then searched for (and found) my character.
But I didn't write it as a comic book. I know how to write comic book scripts, but it doesn't give me the sprawling room that I'm used to in fiction. Instead, I wrote this story, exactly as it appears here, and another writer -- Jake Black -- adapted the comic-book script. So in a way, I "novelized" the comic book before it existed.
Then, in writing Ender in Exile, I used characters and situations from this story as part of what happens while Ender Wiggin is on his way to the colony he is going to govern. So this story is an integral part of the Ender saga. But I also hope that even if you know nothing about Ender Wiggin, this story will work on its own merits. Because, ultimately, it's just a cool sci-fi idea.
