First of all, I know that I tend to find the things I don't like, and not comment as much on what I do. There are many parts in this where my comments are sparse, so if I don't mention something, assume I liked that part. There are a couple pages in the middle where I didn't note anything to myself to come back to later; I assume I was just too absorbed in the story for those.
I'll start with Ezlio and the quills. I wonder how common knowledge of his quills are, since he's taking the time to explain them to Jhuz. However, he says that conventional wisdom about the quills is whatever, and I thought they wouldn't be well known enough to have conventional wisdom. Also, if this is the end of act two, it seems a little late (but not horribly so) for the reader to be learning more about the abilities.
Do the quills only go straight out from Ezlio's body? They're only described as straight out in this chapter. If so, they may not be as useful for blocking things as he thinks.
Later in the chapter, Jhuz gets mad at Ezlio for mentioning his father. It would be neat if Ezlio is doing this on purpose to get Jhuz used to hearing it, and less reactive when it comes to his father. Or to learn how he reacts to it. Either one would be useful for a good bodyguard, because somehow who can be incited to act instinctively (through rage) can be harder to guard, and easier to expose for attacks.
If I were Lexio, I wouldn’t let a man under me who’s drink a drop of wine tonight.
This sentence didn't make much sense to me when I first read it.
Regarding Lexio, and the conversation with him. Did Jhuz never think, after Lexio revealed his metsi, that Lexio was sensing his own weakness and using it to construct a reasonable story? If not, I did, and it might make the story we're reading far more interesting.
Regarding the story of the man killed for meeting with two guilds... even with those facts being true, just them could be enough to make an Emperor cautious. It could be just acting for the good of the people, but it could be someone setting themselves up as the hero of the people, an entirely different prospect. And once I thought this, I would say that you have a pretty good story and worldbuilding going if I'm thinking things like that about what may have really happened in a story related from one character to another.
Ezlio seems to be at odds with Jhuz a fair amount, and seems like he should have known how Jhuz reacts to the mention of his father. That makes me speculate about whether Ezlio is doing little things like this on purpose, and I could think of a couple cool ideas. The best one is trying to figure out how Jhuz reacts to different situations, in order to know how to protect him better. However, it would be even better for protection if Jhuz could be desensitized to the mentions, since if he flies upward in rage at when his father is mentioned, all someone has to do to attack him is mention his father, and suddenly Jhuz isn't (directly) protected by Ezlio anymore.
The missing egg: Is this a detail Jhuz would have noticed? I have to assume so. If he's leader of these men, is it a detail he should have followed up on or made a bigger deal out of?
With the moss on his armor... shouldn't Jhuz have made sure his armor is good before telling the troops to shape up? Wouldn't he at least look at it before doing so?
For the end... in the last chapter, there was a passing reference to Jhuz seeing something that to me was an invisible person... I don't remember the exact details just now, but I read it as Jhuz knows people can be invisible. Then at the end of this chapter, he sees stuff moved around and footprints, and he doesn't immediately think "invisible person"?
Also, I could be wrong, but an attack with a chair seems like it would be a lot less likely to succeed than many other options. I don't know how light the chair is, or how big the tent, but to do a lot of damage it would have to have weight behind it. The way the chapter ended, I'm expecting Jhuz to have been knocked out, or dazed at a minimum, which means it needs the weight. That means someone is either really strong and quick, or Jhuz should have had more reaction time when the chair started moving. A safer way for an invisible person to attack would probably have been to run around any obstacles, get behind the person, and try to choke them. About as good would be to use the desk as a launch to send their own (invisible) body at Jhuz.
Finally, Jhuz is a commander. I don't know how long; the text makes it sound recent, but also like he's had some training in command, so I assumed a recent elevation to that level of command. People with experience of command in a modern army, or most historical arms I've known of, would immediately step out and call for people to capture the intruder. Instead, Jhuz grabs for his belt knife. That would be good if it was his only option, but there should be sentries, bodyguards, or something nearby he could use to help him.
There you go. A bit long, but it seems you've had a wait for it anyway, so hopefully this is worth it.
