This is a Beautiful work. Written for the HeroQuest / HeroWars rules, it describes the Dundealos tribe of Sartar in Glorantha. They're exotic because they're "Horse Orlanthi" and worship Elmal, the Sun God, otherwise it's politics as usual. They continuously fight the eastern threat of praxian and their ancestor killed Jaldon Broken Tooth, the hero of praxian heroes, hence their other name : the Jaldonkillers.
The players start very small, when they're 8 or 9 years old. Even children can stumble on Magic in this world, and they do meet a... Frog spirit. A few years later, now 11 or 12, they have a hard decision to make : should they go after a praxian kidnapper now or call on the adults ? Fast forward a few more years and it's Initiation time, the moment they have been waiting for their whole young lives. It is described as an Elmali Heroquest and has potentially surprising consequences.
This book is pleasant to read, elegantly written, with the love for its subject glowing (it's an elamli thing) through the pages. It's an easy campaign to play, with a lot of wise and useful advice about how to run different scenes. The whole story happens during lunar occupation but it would take little work to fast forward it to 1626.
So if you're into Glorantha, Horses or parenting, go ahead and read this. Even better, play it ! Enjoy.
