Well, let's start with what's on the outside first. Hengeyokai has one of greatest cover designs I've seen in a while. There's good cover art out there, but this is great cover design. Basically the design mimics the Werewolf Tribebooks and Changing Breed books with monotone glyphs on a white background. I'd love to know.
Gold foil is used for the title and central column of characters to very good effect.
Plenty of explosions, snappy side comments, and even a little romantic mooning about. The next two chapters describe the history of the hengeyokai, their philosophy, the physical world they inhabit, and the unique characteristics of the Umbra that they know. These chapters are where the hengeyokai really begin to develop the flavour that set them apart from both the other Changing Breeds. There doesn't seem to be a convenient word that distinguishes one type of hengeyokai from another. Unlike the Changing Breeds of the West, the hengeyokai work together in the great Beast Courts of the Emerald Mother.
