The Peloran are a far more diverse race than we guessed upon initially meeting them. Most of those we met were fair-skinned, fine-boned, and paragons of beauty that would have made them the stars of fantasy or science fiction movies. They are amazing in our eyes. But in the eyes of the of the Peloran, they are genetic defects. Outcasts from proper Peloran society. Proof that even the genetic wizardry that created their race can break down in time. Or be diluted. The true Peloran that inhabit their homeworlds are stronger, hardier, and far less likely to be ensnared in unwanted violence. Which is any violence at all. They are hard hard-wired to seek peaceful resolutions of nearly any situation, after all.
