I know this is not helping either but also there is an Rappan Athuk expansion book out there that has some low level sites in it. That book is about $35.00.
Also, there is a lot of wilderness material in RA. The whole area around the main dungeon has stuff going on.
It also has a bunch of rumors that you can seed around.
I think Tsar has a bunch of rumors too. '
I know a lot of folks like to add things and do a bunch of prep but I am running things mostly as they are written. The only additions for me are places that the group has cleaned out and then left for weeks or months at a time. I have been restocking them.
