This passage reveals more about the way racial hierarchies work in the Stillness. The ruling race of the Sanzed judges everyone else according to their own characteristic traits—and during their time as conquerors, they forcefully spread their genes around the continent by committing rape and genocide. Despite this cruel history, it is considered normal for everyone to elevate Sanzed traits above others in terms of desirability and attractiveness—an echo of how racism and colorism work in the real world. The fact that Hoa seems to have zero Sanzed ancestry, however, marks him as someone wholly alien or perhaps older than Sanze itself.
