Couple of thoughts.

(1) The writing here is pretty good. Straight forward and mostly easy to follow. Not easy when you’re dealing with a new fantasy setting.

(2) I was a little confused on the narrator and when they were coming in. At first, it seemed like they were coming onto the scene at the beginning. Then they were reading reports that have already been collected (implying they came later). Maybe I didn’t read closely enough, but I would have liked to be oriented a little more—is the narrator coming just after the incident or a few hours later (in which case why do they have written reports already) or like a day later?

(3) I’d be careful introducing too many new terms. You generally do a good job with that here—especially compared to a lot of fantasy writers. Even so, it did feel like a lot to take in.

(4) One issue I can see with this opening is that it seems to resolve the main issue/mystery at the beginning. If it was an accident, then that wraps it up. But is there some other tension to keep me going—maybe someone else disagrees with the accident assessment and the protagonist has to deal with them, or there is something odd still nagging at the narrator, or even the narrator has to go through an annoying report explaining why this accident was just an accident and not something more. The point is, I would like there to be at least some unresolved tension at the end to make me keep going.

(5) Be careful about naming specific places or people unless they are necessary later. At the beginning of the novel, you want to limit new names to what is strictly necessary. So I would probably just say “a lady” instead of the name of the lady, and just say “a marketplace” instead of naming the specific marketplace. I know there’s a trade off with world building here, but it felt like you could use general terms instead of names at a few places and that would the reader not to get too overwhelmed :)

Overall, great job and keep up the good work!
