Will the fate of the Werewolf Signature characters (King Albrecht, Golgol Fangs First, Karin Jarlsdottir, Laughing Many Faces,...) be explained in the coming Apocalypse?
The fiction novel (The Last Battle, by Bill Bridges) is where you'll see the canonical final days of the signature characters. There are some fun twists in there. Apart from that, you see some of the characters taking a role in the Apocalypse book, but the book is primarily written so that it can be used as a game; in other words, if we discuss Albrecht's final fate, it's often in terms that imply what that means for the pack (who might be right there).
If it's Albrecht vs. Zhyzhak you want to see, I can promise that there are several potential outcomes, some in Apocalypse, at least one in The Last Battle.

Will all the on-going plot-lines be resolved?
Can't promise that � there are just too many. Not nearly enough of a word count (over 160,000+ words !) to discuss plot lines from the Skin Dancers to the Valkenburg Foundation, with the fate of all major characters in between. But we address a bunch.

As a final mention, the 'Apocalypse' supplement has been sent to the editor last weekend. Once he's done with it, it's off to the printer !
