Have you met the clans? Words like "Naïve" and "misguided" are not enough to describe the notion that a conquest of the IS by the clans would result in a Utopian pacifistic society.
They would be assigned to the lower castes so depending upon when during their training they were cut, their "module" would be a hybrid between the Trueborn sibko and whatever lower caste clan apprenticeship they were assigned to to reflect that they started but didn't complete their military training. Peri would be an example of such a character. When attacked by Etienne Balzac's hoodlums she tries to use barely remembered combat training after years in the scientist caste.
