It's a reference to the Enter Chronicles, but the parent wrote that themselves.

Edit; Ender Chronicles...spallig is hard. :)

Ha, actually I've never heard of the Enter Chronicles; I just made it up in response to the previous comment advocating for sending bio-trash (or bio-treasure?) all over the place.

Lol. I figured that's the only series that deals with ansible communication. Guess not.

The term ansible was invented by Ursula K. LeGuin. Card included it in the Ender books as a tribute.
