Why The San-ti Civilization Is Unstable
The San-Ti home system experiences catastrophic environmental instability because its three suns create unpredictable orbital conditions. Stable eras allow civilization to develop, but chaotic eras repeatedly destroy entire generations through extreme climate collapse and planetary devastation.
How The San-ti Communicate Differently From Humans
The San-Ti struggle to understand deception because their communication does not separate thought from expression in the same way human language does. This difference becomes one of humanity's few strategic advantages during the coming conflict.
Why The San-ti Want Earth
Earth represents stability. Compared to the San-Ti world, humanity's planet appears environmentally predictable and capable of sustaining long-term civilization. Their invasion is driven not only by conquest, but by desperation, fear, and survival.
