I can not recommend this book enough.
I'm relatively new to Torchbearer, but knew it was the perfect fit for the hexcrawler I wanted to run. Unfortunately, the game didn't have an overland travel and exploration system baked into it that was going to handle any of the exploratative itches I needed to scratch.
While doing research into making my own, I stumbled on to Mordite Press and their recently Kickstarted book and realized that it was everything I wanted out of a system and more.
It builds perfectly off of the framework that Torchbearer has already laid out, introducing a new Exploration phase and a handful of new terms that work alongside a modified exploration conflict. The symmetry between the systems is something that I hadn't even considered, and I applaud them for it.
Beyond the Exploration system, the contents of the book are equally impressive. A double handful of new town types and destinations, an assortment of new stocks and classes, an exciting alternate set of rules that breathe life into your mounts and make them more than just another boring piece of equipment. Every page of this book is a treasure trove.
