If anyone's interested in this game but doesn't have a copy, chapters 1-3 of Hero Wars are on issaries' web site, as well as everything important in chapter 4 as a .pdf

I think the Issaries web site is damn strong, and it has an interesting guiding philosophy if I'm not mistaken. Its role is to help out the person who's ALREADY got the game. It's usable, with lots of pictures and maps and interesting myths and other materials. It's not solely for purposes of advertising or "establishing a presence" (that corporate euphemism for "don't know why").
I print stuff from there for my game all the time.
Best,
