Just after Vardis throws the book, you have a couple of paragraphs of... well, infodump.
Not that it's not valuable information - or at least, I imagine it will be as the story progresses - but first off, there's enough of it that I think you could stand to break it into pieces, so we're not getting hit with all of this at once. My larger issue is with the placement, though; I don't think the very beginning of the story isd a good place to put all this. We need to see some forward momentum. Personally, I'd take most of this, break it up, and place the pieces at more apropos moments through the manuscript. For the very beginning of the story, I think "The Prophecy was the one holy book still held as the true Word among men" is enough.
As I read, it seems to me that you're using this information mostly as a segue to tell us about Vardis's motivations, which I don't think you need to do. Let's see him act on his motivations, and give us the piecs we need as we go. Readers are smart, patient people and they'll be happy to follw you along.
The above were my thoughts as I was reading the prologue; now that I've finished it, I think that you've started your prologue in the wrong place. In this prologue you have Vardis
reflecting on his moment of discovery, when he found the translation issue in the prophecy. Instead of having him
remember this moment, why not show us the moment itself? It would be much more immediate, for one, and since that's the moment your prologue basically revolves around I think it would make much more sense. Also, I think that redoing the prologue that way would help erase some of the infodumpy stuff that I mentioned previously. Just my opinion, of course.
You've got off to an interesting start with Garrick and Dren; I'm curious enough about the ruse they're pulling - and why they're pulling it - to keep reading. A couple of things, however...
Dren's line about the Hand's door, "What fool would dare enter", doesn't sound like real dialogue to me.
I think in order for the chase into the Hand's house to be effective, we're going to have to know a little more about the Hand, and why this is SO terrifying, why it's SUCH a hard choice. As it is, I'm not really convinced. It seems to me that their fear is told rather than shown, and that coupled with the fact that we know nothing about the Hand means that the urgency of their situation falls a little flat. The man that shows up in the house doesn't seem to live up to the hype, either. Sure threatening them with a knife isn't very nice, but it's no worse than what was facing them outside. Again, I think this is a problem that we just don't
know enough. We don't know enough about the Hand to know why they're really frightening, and we don't know enough about the characters to know why we should care about them.
At this early stage, I think you only need to "fix" one or the others for this scene to be effective... but I think there is a bit of patching to be done.
I also thought "aquiline" was a bit of a weird word to describe a dagger... but it has nothing to do with horses, which are equines.
Strong start, though.
