BIND is a ‘PIY’ book, meaning ‘Print It Yourself’.
The modules come with various handouts, including maps, and local price lists.
Price lists contain rare items and temporary prices, so each market is different. Players don’t need to fumble through the rulebook for purchases - a new sheet comes up, only when in the market.
Every time a module refers to an NPC, the NPC’s full statblock is printed on that page or the next. Each statblock has boxes to track Health Points and Mana Points.
The Book of Stories comes with Character Sheets ready to tear out. It also comes with a minified rulebook, so everyone gets a copy of the rules without taking up space at the table.
There is no definitive map of Fenestra - just pages with ten points, waiting to be filled in with the lists of random map features. You make your own map.
