There are a total of 11 pages of bonus comics integrated into the story. The bonus comics, like in the books before "Don't Split the Party," are scattered here-and-there to fill in a few things and add some humor. There are no new "mini-story-arcs."
The special feature "Quoth the Familiar" is 5 pages.
There's a very old but never-before-seen OotS comic where Durkon "Turns Undead" which is 1 page.
There a story recap (much like in the other books) done by OotS characters which is 3 pages.
A single-line page featuring Celia at the very end of the book. (Similar to what we've seen in older books)
A 1-page preface by "Durkon Thundershield"
A 1-page forward by John Rogers.
A 1-page intro by Rich Burlew, plus 11 other pages of author commentary (Chapter 9 got 2 pages.)
Anything else folks want to know? Someone else can do the characters-by-page-count thing.
