Chrysalids

A small difference or discretion with people or creatures outside of Waknuk is an offence. People with a difference from "God's norm" are a blasphemy.

Usually there was only some small thing wrong, but however much or little was wrong it was an Offence, and if it happened among people it was a Blasphemy — at least, that was the technical term, though commonly both kinds were called Deviations.
