This is the sourcebook for the game, Werewolf: The Apocolypse.  It's about the GlassWalker tribe and guides the player through character creation, offers some sample characters, and talks about the culture of the Glasswalkers.

This copy is in pristine shape, and the only marking inside, on page 9 (just after the full color comic that's included) is my first initial and last name.  No other markings exist inside. The pages are crisp, and the binding is unbroken.
