^ They don't have to be at odds at all. The stories will just continue 5 years later.
I can't imagine a Trek editor inheriting an ongoing story that ended with such an obvious setup as Iliana appearing before the Ascendants, and then saying "well, since we're skipping 5 years, we're just going to ignore this completely."
As *I* have exhaustively enumerated in other threads, every dangling thread can be carried on perfectly reasonably after the time jump. And as Christopher says, it's not like these are real events that we're just chronicling. If the authors decide that those stories will continue after a jump of five years, then they will.
At the very least, I think we should stop complaining about the dangling threads being dropped until we read TRBOE, hear what's next for DS9, and actually see if the threads are dropped or not. Because there's no reason at all that the 5 year jump necessitates dropping them; none whatsoever.
But I like complaining! Actually, I don't really, but I do feel genuinely disappointed that they couldn't have written a novel before TRBOE dealing with the end of Soul Key and all these Ascendant/Dominion/Emissary/Evoq stories that are so rich for mining, before we get to Destiny and Typhon Pact. That's what I mean about their being at odds. Of course, that's life, can't always get what you want, etc. But that is how I feel.
And at the risk of fanning old fires, Christopher's invocation of "its not like these are real events" is totally besides the point -- If Captain Kirk suddenly wore women's dresses and spoke with an Irish accent I think the fact that "its not like these are real events" would hold any water with anybody. The point being - at a certain point, you can't just "write anything" and maintain the cohesive reality that all of the post-Nemesis and DS9 relaunch books have remarkably achieved.
I agree many of the plot elements have the possibility, without violating that sense of "audience objection", of being put on pause within the logic of the story-world for a while, Illiana, the Ascendants, even the Dominion's new state, etc. But not all, at least not without being a rough fit, and without stretching at least this reader's sense of credibility.
My concerns, which I like to come on these boards and commiserate with fellow readers over, is twofold: In the worst case scenario for me TRBOE will pick up after these story lines have already concluded or had some major action occur in some way and then possibly refer to them as having happened, reflecting (I should hope) some kind of major change or aftershocks and asking us to catch up on the run, and to come back to a flash-back book or books to learn what happened. This doesn't appeal to me in the abstract (of course, allowing for myself to be again wowed by the amazing stable of Trek writers!) since I would have liked to have 'been there' for these events.
Second and less-undesirable possible scenario would be that we'll be asked to believe - again, within the established logic of the story and its needs (which I believe is, at heart, what those who disagree about the value of the jump are debating - ie just what those needs are) - that nothing of import has happened affecting the world of DS9 much in five years. On the face of it, this is pretty unbelievable since, well, its DS9 we're talking about! Again, straining the limits of what we might be asked to imagine (yes, imagine!) is a real world that behaves according to its own laws.
Anyway, since the DS9 relaunch has happened we haven't been asked to do anything like either of these two scenarios and so this is why I'm just slightly annoyed by the DS9 relaunch -- not because of the MU stories, I was willing to go there! Just because of what I perceive to be the vicissitudes of commercial publishing and editorial staff changes impacting, hopefully not too greatly, the otherwise rich, magnificent, and finely-wrought world of 24th century Trek that has been established.
But I hear you, Thrawn, I'm pulling for the best! But misery loves company, too!

And its a long way until TRBOE! Gotta stay fresh on the details until then and chatting with you guys is a fun way to do that.
