I don't think I'd go so far as to call Amblin's caretaker abusive. There were chores...lots of them. They were, of course, life lessons. The lessons they taught, however, were often unclear at best and more often unfathomable. His master, Chelis, also never bothered to explain anything.
In their house, cleanliness was more than a virtue, it was a lifestyle. Amblin took to rebelling in his own little way by sprinkling a pinch of dust in some obscure corner of any freshly cleaned space...mostly for spite.
Amblin's childhood was like working for Mr. Miyagi in the Karate Kid...only there was no going home at the end of the day, it lasted for 13 years, and there was never an explanation of how or what he was being taught. However, now that he's been out on his own and finding all manner of trouble, Amblin realizes just how many skills he has at his disposal.
