From publisher blurb:
Welcome to Sandwalkers, a useful resource for the post-apocalyptic role-playing game, Darwin's World 2nd Edition. Sandwalkers is intended to serve as a practical GM aid providing concise information on a number of pre-generated NPC heroes and villains, potential campaign allies and enemies that you can slip into your games with little or no preparation.
How To Use Sandwalkers
Sandwalkers is filled virtually from start to finish with characters that you can use to fill out possible voids in your adventures, providing well-developed non-player characters with complete stat blocks, backgrounds, physical outline, and even a description of favored, pre-planned tactics for each NPC - as well as possible "hooks" for encounters with or against these unique and unusual characters.
Each character described in this book is designed to be a challenge for a particular level of game play, ranging from low level (5th and above) to the most epic (topping out at 20th level). In addition, each character not only represents a varying level of danger (or help), but also hopefully a unique "take" on each advanced class that will give more depth and variety to the more obvious faces of Darwin's World's numerous iconic character types.
