I'm quite agreeable to the 'no particular order' strategy. Let the chaos ensue.
I'm rather taken with the idea of Muriel being mistaken for Linduial. What about other mistaken identities? Anything else possible along those lines? Is there any way that the four different groups of Eodwine's patrol could mis-perceive something such that it seems like there are more men allied with Sorn than there really are? For example, maybe Deren's men hear Thornden's men on the other side of a wall and assume that they're Sorn's men, and start up some "friendly fire"?
