Well I'm at the H&S nebula area now ,looking back towards the core i see this
http://i.imgur.com/0TXBLY8.jpg looks like the jewels in a tiara to me ?. It looks like its the IC1805 open cluster . what if the rift is the gap between the heart and soul nebulas, and the "core of the problem" and " watch your six" mean to look back at the galaxy core after going between the H&S nebulas ?
Im on my way back to IC1805 now for a closer look
I like the idea too, but I think it would contradict the message about having to plot a way through the rift and there being no stars for dozens of light years...
I had been avoiding this thread for a while until I'd read Reclamation, but seeing as I finished it last night I'll be paying attention again.
Some thoughts on the comments...
1. I suspect that if we find whatever is out there, it will be protected, and we're likely to be attacked. This, I think, is the main reason behind the "watch your six" comment.
2. There seems to be a lot of speculation at times about the continuing theme of Kahina not wanting to be late. I suspect this is just a character trait (based on one of Drew's comments about mainly being a character writer). This would make sense as something to set her apart from most Imperials who like to be "fashionably late" to meetings and such, as mentioned near the beginning of the book.
Nothing particularly helpful, but just some of the assumptions I'm currently working under.
