Keith Ammann is the award-winning creator of the blog The Monsters Know What They're Doing and author of a series of books by the same name, including the recent Making Enemies: Monster Design Inspiration for Tabletop Roleplaying Games and How to Defend Your Lair. He's been a roleplaying gamer and game master for more than thirty-five years. He likes to play outwardly abrasive helpers, out-of-their-element helpers, and genuinely nice, helpful helpers. Mostly, though, he plays non-player characters. And monsters.
