Okay, I finished everything posted so far. *phew*
It's clear that you did a lot of research for this retelling and the results are great and make for an enjoyable read. The names of people and places fit in well, along with the descriptions of the geography (I especially liked the sci-fi passageways between worlds being replaced by dangerous mountain passes).
I'll admit that I didn't see the statue was going to turn into Wren until it happened, but I think he might be my favorite changed character in the whole story so far. Finding the solution to bringing him to life seemed a little rushed, but there was plenty of other action (and action scenes!) in this story, so I didn't mind. A tiny Laya/Layla also took me by surprise, but I'll admit to her riding around on Na'il's shoulder was kind of cute.
As this is clearly a fantasy story, I was open to the various dreams where Laya/Layla visited Nial/Na'il, but I'm not sure about how I feel about the whole table of pastries and repeated mentions of "moon cake". I know that dreams don't always have to make sense, of course, but the references to the cake that was supposed to represent Alair throughout seemed a little odd. I guess I can sort of accept that Na'il refused to choose a wife based on the dream (though it's a little bit of a stretch), but using dessert as the vehicle to get the point across was an interesting symbolic choice.
