I saw your post about creating a NWN persistent world in the 5E area. A friend and I had been considering doing so ourselves. The goal was instead of focusing on any one area, to slowly build all of feruen. The PCs not being the heroes of legend, but simply adventurers which may alter the world through their actions.
Currently I have Shayran's subrace engine (any race desired, with the LA added in) with the NWN persistence world module added in. I was curious if you would like to work together if our goals are compatible.
