I've read reference to this document from the D20 days, but haven't been able to find it anywhere. Was it ever published?

I don't think I've ever come across it.

Hello,

No, the author finished the manuscript but decided to completely ignore canon and mythology and came up with his own version of what I asked for.

I had to nix it completely and just incorporate many of the items I wanted into the original living campaign adventures I wrote.
