The prose is compotent. The exposition is passable, a bit stretched over maid-and-butler in a few places, but decent considering you're working with a world of elementals that is completely original.
The real problem is with structure.
The scene opens with everyone "assent"-ing (which kind of reminded me of Power Rangers, tbh). Then, there's some petty bickering. I'm assuming that by chapter 5, everyone knows what assenting is and knows preliminarily the personal conflicts of who is stronger than who (if they don't, there's a problem). But given that everyone knows this, the intro doesn't pose any dramatic questions. I'm not asking myself what the eff is assenting, or what the H they're arguing about. Furthermore, these dramatic questions are only really suitable to passages where you want to exposit detail, not chapter 5. Chapter 5 questions are those such as "will X reach her destination?", "what is the nature of this obstacle?", "how will fact X that main character DOES NOT know impact her?", etc. In sum, this is a bad intro to Chapter 5.
A good example of other structural problems is the scene break where it's announced that some people are attacking the castle/fort, and then the next scene jumps to dialogue about how it's more fun to have relations with the water elemental. Then, the attack is thrown aside easily because there were only 5 people attacking. I don't know what dramatic question I can ask myself that hasn't been answered already.
Another one is the death/ascension of Ristem scene at the end. You've got the prose style of short dramatic sentences down pat. But I can't put myself into the scene because Ristem's life/current existence/whatever was never at stake at any point. There's just a few mentionss that the ascention will happen regardles of what the characters want or try to do to prevent/further it. The mentions of the ascention actually interrupt the characters' dialogue about their day to day. I actually scrolled up to see if I'd missed some hint that the characters were trying to prevent/further his ascension, but all I found was two people discussing why someone's getting a new servant assigned. Accordingly, there can be no satisfaction for me. No question is being resolved according to or against my expectations.
I think it would be helpfult to take a few minutes and outline the major dramatic question of the novel. What do you want the reader to root for? Decide, and then place as fearsome of an obstacle as you can to impede the outcome I'm rooting for as a reader. Show me the rooted for outcome and make me want it too. Show me the obstacle and made me feel it. Then surprise me.
That's what structure is all about.
