From the introduction: Ahead of you are moral tales, a slew of new beasts and the briefest possible overview of Fenestra – just enough to start to move about in the world and describe it. The order of the sections are unimportant, so if you want more detail, skip imediately to the appendices at the back for a look at the mythology and cosmology in play. If you're really just looking for a few monsters to drop into your own stories, jump to the bestiary.
