@Olo Happy to get into it! While I do plan to make this at least a trilogy (eventually), I don’t think these are spoilers since I’ve already alluded to it a lil bit. I haven’t thought of a specific shrinking method, but whatever it is, it also affects other physical traits and not just their heights. I almost imagine some kind of super fancy personality assessment that either scientifically or magically determines what their size/appearance is meant to be in their new life.
It is indeed “voluntary,” (though there’s quite the selection process involved, both for the customers and for the merchandise). It’s voluntary in the sense that these ladies fully consent to it and understand what they’re agreeing to… but they might also be in a place in their lives where they don’t really have any better options.
It is completely underground/secret, and I’ll say they’ve probably only been in operation for a few years because I just don’t see how word wouldn’t eventually make its way out… despite the fact that there’s probably all sorts of NDAs that the owners have to sign, and that (most of) these ladies are happy with their situations and thus not trying to escape. Not sure if I’ll end up doing anything with that part of the concept or not, I just enjoy the whole secrecy aspect and wasn’t particularly wanting to make a world in which this is normal lol
