This page is called Richard Staats at Work and Play and also has some information about another campaign setting (called Khymir), as well as music, YouTube videos and lots of other things that Richard Staats is involved in.
So there is quite a lot there, but as I don't know what Zhalindor is like in Tortured Souls! or GameMaster Publications, I'm not totally sure it is the same thing. And I'm not totally sure what links are about Zhalindor (and what links might be about Khymir or something else) but if anyone has access to the magazines, they might want to dig about, as I think there is some gold here.

There also seems to be a website out there, by Mark Thomas (one of Richard Staats's players), called: The Zhalindor Campaign.Richard Staats wrote:Zhalindor is my fantasy gaming world. If you are interested, feel free to run your own adventures there! I would be glad to help you set-up plot lines, etc. Hundreds of gamers have had the pleasure of playing in Zhalindor over some 25+ years. My site includes a large amount of information on Zhalindor. To get started check on the Kernan links (below on this same page) or Zhalindor page. The world is absolutely huge (about ten times the surface area of Earth)! DISCLAIMER: Zhalindor is a collaborative effort. I did not design the entire world from whole cloth myself. You'll see elements liberally "borrowed" from many sources. Check out my article on World Design to see some of the references.
It looks like Richard has run at least 20 different Zhalindor Campaigns (dating all the way back to 1976). One of his campaigns ended in 2014, but it looks like there are two that are still going,
One of the campaigns that are still going, is called Sins of the Forefathers. I also found an archived Geocities page called Zhalindor Campaign: Sins of the Forefathers (SoFat). I don't know if that same information is somewhere else on Richard Staats's website, but the campaign actually started way back in 2006, so the page might have out of date information about Zhalindor.
