They say writers shouldn’t hesitate to kill their darlings. It’s not an invitation to actual homicide, but a plea for the willingness to jettison any element of a story, even if you love it like a friend. That’s just one of the many work-hazards writers share with those in charge of Dungeons and Dragons games—a dungeon master has to kill off his or her friends all the time.

Consider pouring out a flagon of mead, in that case, for poor Matthew Robinson. As a pro screenwriter and a recent convert to the world of Dungeons and Dragons, he is constantly deluged with decisions about character arcs and turns of phrase by day, and also responsible for the fate of those fellow D&D-ers whose weekly quests he architects. Naturally, he has found that there is some serious overlap between the skill sets of screenwriting and overseeing fantasy roleplaying games.
