I will say, having never read any of your previous DR stuff, I was still able to follow the chapter fairly easily. So, here are my comments:
Firstly, I have to agree with whoever mentioned Wheel of Time. Every single time I see Mordin, I think of Moridin from WoT. I even started to type Moridin instead of Mordin right there. I don't know, maybe this is a good association. Moridin runs around wearing black all the time, and generally being insane. If this is the feel that you're going for, it's a good association.
Also, is Mordin supposed to be the antagonist? Because he comes across as very anti-hero/misunderstood-protagonist-ish, and if he's supposed to be the antagonist, he also comes across as remarkably incompetent.
I, too, thought that Cillia was a previous love interest. I think it might be the line where Mordin says, "Cillia has nothing to do with it," cutting off Ednar. It makes it seem like it's a very touchy issue for him, and they've just been discussing love interests. Then, after we've established that it's a touchy subject, he says:
Despite this, they had been close growing up. Mordin had looked up to him and still did after a fashion, though most of his relationships had been strained in the last few years, even before Cilla. Ever since….
The way this is worded implied (at least to me it did) that Cillia was one of those strained relationships, or that she was someone who both brothers had been interested in, leading to some strain between them. The current princess didn't even occur to me as a possibility. So later, when we found out that Cillia was the current princess, it was like, "What? She's Cillia?"
I also agree with whoever said that he needs to think of the new princess as Cillia. If he knows her well enough to know her name, he would think about her using her name. Especially since he's a prince himself.
The whole thing with the bag seemed kind of sudden and random. It was like, "Oh, I'm upset that this crazy chick is marrying my brother. Hmmm. Hey look, her bag is conveniently right here after I was just thinking about how suspicious it is. And that happens to be exactly what I need to find out what's going on. I know, let's steal the bottle out of here. Ok!" The whole thing just seemed like it was too easy for Mordin.
So Mordin's an antagonist, eh? In that case, have him plotting to steal the bag, having previously noticed the connection. It makes him seem more competent, and it is a little less convenient.
I found it interesting that Mordin steals the bottle, and the first thing that occurs to him is that the princess is a drunk. He was just being really suspicious of her, so why wouldn't he think the bottle was something more sinister. I actually at first thought it was like a love potion, or something along those lines. Shortly after that, I was thinking poison.
If Mordin thinks the bottle is common alcohol, why does he steal it? Is he just so cheap that he can't afford his own drink? He has to steal the princess's....
"Is that Raven? When did she get so big?" This line causes all sorts of problems. As Chaos mentioned, I thought at first that Raven was Jade's daughter. It also immediately establishes Raven as being considerably younger than Mordin, even more than the four or five year difference that (we think) we have there. After all, a 10 year old doesn't usually look at a 6 year old and go "She's so little!" Then a few years later wonder when they got so big. Children and teens don't typically comment on things like that, since they're growing also. It's a distinctly adult line, that makes Mordin seem older than 17 or 18. I'm 17. I would never say that about someone who was 13. I have said it about people who were 2 when they moved away, and 6 when I saw them again. But that's a major difference in age, and I didn't see them in between. From what I gather, Mordin is making regular visits down to Jade's, which means he would be very familiar with her and Raven, not this sort of 'first time I've seen you in forever' reaction.
Does Mordin actually believe the people at the temples when they say that theirs is the only safe magic? Because if so, he should mention that theirs is the only safe magic, not that they say theirs is the only safe magic. If he doubts it, as this phrasing makes it seem, then he shouldn't be so quick to agree with Jade that the traveler's tales don't matter. For that matter, why is he so quick to agree? It seems a little naive to just assume that your magic-users are right about everything, and the travelers tales count for nothing. Unless this is a culture where the magic-users are right about everything, or everyone thinks they are. In that case, you should bring this up before hand.
Why does Mordin suddenly just decide to pull out the bottle? Does he not like whatever Jade gave him? Is he curious about Cillia's taste in liquor? Did he just barely remember it? No matter what the motivations, they aren't stated, or even hinted at. The bottle just kind of randomly appears again. Never mind, I just read the line where it says, "Jade hadn't left anything, so...." Yeah, disregard that entire last paragraph there.
The prince seems to feel at ease with the Djinni awfully quickly. Like two seconds ago he was cowering in terror, then he's calmly conversing with it, then he's setting it free. He never thinks even once to question the Djinn. Also, you have a line, "The djinn didn't say anything, but it's smile was all the confirmation Mordin needed." How, exactly, does one with a gaping hole for a mouth smile? Furthermore, why is the djinn smiling about that? Did he do something unpleasant to his previous master that he's remembering? Did he love cillia very much, and smiles to remember her? I realize that this isn't really important, but I sat there for like 10 minutes going, "Why exactly is the djinn smiling?"
Mordin initially wishes for Cillia's enchantment to be lifted and the Djinn to leave forever. Why doesn't this count as a wish? I was surprised when the Djinn didn't just say, "As you wish" and poof, everything is back to normal.
When you say corporal form, do you mean corporeal? That's what I thought you were trying to say, but I wasn't really sure. If you really do mean corporal, you might consider capitalizing it and telling us what the heck that means. Otherwise, I sit here going, "what does a rank in the army have to do with a genie?"
You describe the djinn's attempt to look innocent. Then you go back to Mordin just instantly trusting it. Half the time he seems to doubt, half he seems to trust. He needs to be more consistent, or we need to see the internal struggle if he actually is feeling conflicted. Either one would work.
Why does Raven agree to spy on the Bearers? Is it because she actually has feelings for Mordin? She seems to change her mind about whether or not to go to the temple awfully fast.
The whole thing with the kiss. I don't have as much of an issue with the fact that she's thirteen as I do with the fact that the entire thing was just like, "Wait, what?" It wasn't really foreshadowed at all. In all the previous dialog, they seem to be fairly distant, and then all of a sudden, Raven says something mildly suggestive (which is apparently fairly common for her) and they're like, "Hey, let's make out!"
I would also expect Mordin to have some issues with kissing Jade's sister, since the relationship between Mordin and Jade is developed more strongly in the first chapter. Even if they don't like each other that way, they at least are good friends, and Mordin's got to be thinking about how she's going to react to him kissing her sister.
Overall, I really enjoyed the piece. It seemed like something I'd like to keep reading. But it did have its own issues.
