Not one trace of imperfection was allowed to show in the children, especially disobedience. The moment one of them broke the rules, torture-like punishment awaited them!
They trained these orphans like dogs, instilling absolute obedience into their growing minds. The rowdy kids would be punished, and after enough punishment, the kids would have lost their usage and thus be disqualified and disposed of. The kind of disposal method was never revealed to the children, they only knew some of their friends would suddenly disappear overnight.
All the children were incredibly young and none of them had the ability to survive and look after themselves. To prevent the fate of abandonment, they would transform into loyal dogs and would answer to every order the adults gave them.
