The Adventure Burner is the third supplement for the Burning Wheel Fantasy Roleplaying System. It provides a system for setting up and running sessions, adventures and campaigns. Examples are provided in the form of three ready-to-run scenarios - The Sword, Trouble in Hochen, and Thelon's Rift - and 42 sample characters.
In addition, this volume provides extensive insight into the Burning Wheel system. 150 pages of commentary guide the reader through the game and its application in play. A handful of new and clarified rules complete the book.
This book is a must read if you are new to Burning Wheel and intend to run the game. I've read the two core books multiple times, and played Mouse Guard (which is a variation of the system), but several key elements of the game didn't click until reading this book.
It probably also has some use as a general RPG design theory text.
