"We are still studying the biological changes in the strange new races of man that kawaru has unleashed upon the world. Their reproduction, and the continued occurrences of the mutation event, remain a puzzle to our best minds. How is it that some of the Changed breed true, perpetuating whatever form they have taken, while others produce children who are perfectly normal humans? Still others have offspring who appear to be normal humans, only to experience kawaru later in life, when they metamorphose into some thing else. Even the best genotyping cannot predict who will be affected or what he will become."
