Sorry for not responding and letting this drop off. I just haven't really felt as enthusiastic or passionate about talking about the story this time around. As I've said some of these things are only possible if you assume that regulators are preloaded with a soul. And I am starting to think that with these and a few other things the writers didn't really think about them too hard or past the initial idea.

Which sucks as I liked the story while going through it and enjoyed Wuk Lamat. I even understood why she continued to come along with us. I just hope they explore more about how the Alexandrians and the few Turali who wear these think about the regulators and what it really means to wear one. Especially when they barely scratch the surface of this life style via the side quests and how some are just now feeling a bit uncomfortable about it all. Not being able to remember a parent/person who fed you such wonderful meals that they might as well be a living person eating food in living memory. Or that there's a little regret in not being able to clearly remember a friend who talked you into using them after having a talk about it over a few drinks at a bar. And even if it wasn't explored what would it mean if a child had lost their parent during the attack due to running out of banked souls.

All I know is this system isn't really sustainable and probably started up at a high price. That and had a lot of trial and error if the lines in Alexandria are anything to go by.
