So far LWD hasn't expressed an interest in selling settings files for Savage Worlds, so the majority of them have just been fan-built. For official Pinnacle settings, however, they do have an agreement in place to allow those fan-built settings to go into the official updater, but the creator has to host the file and LWD does a sanity check of the file before allowing it to be added in that way.
All I can say for sure right now is that I have a partial Evernight file done, but nothing else that I, personally, have been working on and I've just been too busy with other stuff to bother trying to build one for anything else (especially not for Lankhmar since I don't foresee my own group wanting to use that setting anytime soon.)
You could always try and take a shot at making a file for it, though. I tried writing a brief tutorial in a thread here called "
So you want to make a data file?" which could help you get started. Even if you don't add any of the coding to automate things, just doing the grunt work of copying and pasting in all of the text for gear, edges, hindrances, etc. may be enough to get one of us on the forum helping to finish out the file for you.
