From the publisher's website:
Now Glorantha has come to a new generation of players with the release of HeroQuest. To accompany the launch, Issaries, Inc., is bringing out a range of game aids. The most substantial of these is HeroQuest Voices, a free PDF book containing introductory narratives for all ten homelands described in the rules, as well as for seven other peoples and races. This 64-page book uses the same format and double-page spreads as HeroQuest and other recent releases from Issaries, Inc., and contains more than two dozen illustrations.
Although some of these narratives have appeared before, they have been updated to reflect development of the world over the last fifteen years. Additionally, project coordinator Nick Brooke has assembled many new pieces written by some of today's key Gloranthan authors, including Greg Stafford, David Dunham (co-creator of the King of Dragon Pass computer game), and Mark Galeotti. The narratives are illustrated by a variety of artists, both old and new.
