Gorr Holl ("Growl", get it?) is described in ch. 9 on p. 85 and is so obviously the model for Chewbacca that I'm astonished that no one has ever made the connection. And Varn Allan comes across as a Leia character, albeit as an administrator, not a princess. There's even a galactic senate.
A must read for anyone who wants to piece together some of the origins of Star Wars.
