Interesting chapter. Is the way that Awakening works a consciously different take on the Eddings Will/Word system? It seemed similar at first (in application -- focus your will and then say the words -- if not underlying theory), but the sound factor -- which seems like it should maybe get more attention throughout the book -- changes things up. My intuition was that something like "Hold Things" would take more Breath than "Hold That Branch" because the first requires more work. But that seems to have nothing to do with it; in fact, with Awakening they have a system for perpetual motion (and thus energy). A wheel Commanded to Turn would turn forever, a Lifeless horse Commanded to go back and forth between two points at certain times would do it to the dot every single day, etc.
It's purely my own preference and shouldn't get in the way of the core story, but I think it's a marvelous chance for imagination to flesh out in a purposeful way what a city like this would look like and how it would operate -- Hallendren right now feels like a typical fantasy/late-medieval city, relatively untouched by the influence of Breath. Yet look at all the ways our world has changed in the few hundred years we've had electricity. So do you want to emphasize the plight of the poor in the slum? Have Vivenna see that most of the menial jobs in the city are done by Lifeless, since business owners wouldn't have to pay them. Want to present the city as an orderly system? Show that Lifeless are used to deliver the mail or provide public transportation at precise schedules. Want to present the city as decaying and decadent? Describe that those same Lifeless are starting to fall apart and the schedules falter, or have Awakened ceiling fans spinning endlessly in the houses of the rich, while poor Drabs suffer in the heat....
One thing Vasher's explanation didn't address is Drabs. Is a Drab thus someone without BioChroma? This may fall under the "we don't know everything" category, but why then cannot a Drab be Commanded?
Realizing that I read the version 1 edition of all the early chapters, has Vivenna's character pre-betrayal been changed at all in the later drafts? She seems to see her earlier self a little differently than I remember her. In this chapter she's going on about how sure of her beliefs she used to be, but my memory was that Denth started challenging her beliefs almost as soon as she arrived in the City, which is pretty much when we were introduced to her as a character. Reading her take on herself in this chapter, I might suggest -- if you haven't already -- making her even more arrogant and sure of herself, less questioning, in the earlier chapters, delaying some of her inner doubts until a bit later. Denth might challenge her beliefs a little less, encourage her contempt of Hallendren a little more (wouldn't that be more in his interest?). That would allow us to see her transformation as more substantive now in these later chapters, and also better contrast her with Siri in those earlier chapters.
Edit (addition):
It bugs me how Vasher won't answer her questions though. I wish he would/could be more open... if even just a little about nightblood. We don't even have an idea of why he/(it?) would make her sick when she touched it. It seemed like it was a test or something from their first meeting... anybody have any guesses about him, because I don't really?
My take is that Nightblood is one of those "only ye who is of pure intent may draw me" type devices -- the evil you have in you, you have done to you. But it may be something more specific. Vasher's silence is one of those things where he really needs to have a good reason for it -- nevermind Nightblood, he still hasn't told Vivenna what his ultimate goals and plans are and who he is working for/with.
