This is not the most original request but the other threads I've found on this topic often point to persistent world servers. I would like reomendations for offline open world modules that work with the non-EE version of NWNs and don't rely on things like the CEP. I've searched through the Neverwinter Nights vault and found a couple that meet my criteria like Abeyance but they were unpolished. The vault in general is so big that it's difficult to find exactly what I'm looking for.

Any recomendations for offline, non-EE, non-CEP, open world modules?

There's Wulverheim, but's it's for NWN2.
