I'm planning on starting to run Rise of the Runelords, and am planning on making some adjustments to the plot. Based on a previous conversation with James Jacobs, I'm concerned that some of the things I'm thinking of may conflict with things in Return, which I'm interested in running at some future point.
I can't really afford to buy Return at this point; at least, not just for the sake of checking whether my changes will be cause issues if I ever end up running the AP. Of course, I'll buy the path if and when I start running it, but in the meantime, would someone mind explaining the plot of the path to me in detail? With particular emphasis on what Alaznist gets up to (and has been doing before the path began) and on the time travel elements? Many thanks.
