BOLD is the book of legends and deeds. With just a handful of dice rolls, BOLD can generate interesting character histories, downtime events, and even adventures. Any character instantly obtains deeds and legends that are overcome in unexpected ways. These deeds can even arc out in to entire stories.
Best of all BOLD is system and setting agnostic. It will work in mouseland fantasy just as well as pocket-dimension town or sci-fi detective stories.
