Many of those children in the compound don't know who their parents are, or where their parents live. In this cult the humans are components and can be reassigned to different units, even the children can be reassigned as some were to this compound. The female children are being bred and raised to be used in marriages, the males are sometimes kept to serve as husbands and leaders but are also thinned out mercilessly when they come of age to compete with the older men for the carefully cultivated girls. There is no security, these people are not a family unit. The cult is evil, not different, this is a rescue.
You seem to have the inside skinny on this group. How and why do you know so much about them?
