Well, I must confess I simply haven't had the time to do more to the saga, and the longer time drifts by, the more I forget on what progress was made.  I did however take a peek over the Christmas period.  There's a fair few conversations that need expanding, and that can be terribly time consuming.  It did leave me wondering if I should consider re-installing NWN2 and making part two within that, but I suspect the learning curve would destroy my will to go  on.

On reflection, it makes far more sense to stick with NWN1 simply because of the amount of work already within chapter 2.

I'd still be very interested if someone out there might be willing to help.
