DR: Who came up with the idea of a biologically based technology and a culture with a fanatical aversion to machine technology and a value system and sadomasochistic theology based on conquest, violence, sacrifice, and pain?
SS: Bob Salvatore invented the biotech concept, which we liked. We built on that to come up with the fanatical aversion to machine technology. We kind of liked the flip-flopping of the way it had been in the original movies: there, the high tech was mostly in the hands of the bad guys, while the good guys wore homespun and seemed much more low tech. So here it's the reverse: the good guys are high tech, and the bad guys seem more low tech, although they're really just "different tech." The sadomasochistic theology was not planned, and while we tried to pull back on it, not stress it so much (we really wanted it only to be the extra-fanatical Domain Shai-of which Shedao Shai was a part), it took on a life of its own.
JL: the time of the first story conference, I had just returned from an extended trip in Mexico and Guatemala, and during the brainstorming sessions, Del Rey editor Steve Saffel wondered aloud if the Aztecs or Maya might serve as models for the Vong. We began to work with this by imagining a kind of organic-tech Aztec society with a pantheon of gods, rituals of automutilation, a rigid caste system, and a hatred of machines. We weren't out to reinvent the wheel. We were simply trying to come up with villains who had the potential to become as interesting as Palpatine and Darth Vader. Our original conception of the Yuuzhan Vong expanded in all directions after Bob Salvatore, working from scant notes, gave them an actual look and created examples of their wondrous biotech. Mike Stackpole was largely responsible for the system of ranks, and we borrowed heavily from Central American mythology in creating the pantheon of gods. Kathy Tyers and Greg Keyes contributed immensely to this process, further defining the warrior and shaper castes and in enlarging the Yuuzhan Vong menagerie of creatures. Yuuzhan Vong words and phrases accrued as the series progressed.
