A world remains primitive because the dominant species refuses to progress with technology. They kill any scientists and despise any inventions. One prophet emerges who summons a series of kaiju, (the Progressors) each one representing an invention. When these monsters breathe their special gas, the invention comes into existence and is suddenly commonplace. Eventually the population draws a line at air machines. They consider flying to be a heresy. They kill the prophet, who, with his last dying breath, summons Yanapla, who represents airplanes. The populations goes to war with the monster.
