Small bundles of pages to keep track of their various Promises and obligations. In later years, accounting books became all the rage, each noble upping the ante.
Accounting books also became kind of journals for nobles. After passing into Solace, many accounting books were published by friends and family members—with proper editing for decorum’s sake, of course.
