From the introduction:
This product is for Realms of Pugmire – i.e. both Pugmire and
Monarchies of Mau - for Guides that want to deepen aspects of travelling in their stories – add things such as chases, random encounters on routes or getting hungry or poisoned by someone. It raises stakes from original setting, so it’s only for Brave Dogs and Excellent Cats. Will you dare?
The book includes chase rules, hunger and thirst rules, random encounter rules, and several sample encounters. The covers are included in the pagecount.
