Libellum

The libellum (or little book) is a libromancer's main reference book. While unique to every libromancer, it typically contains notes on physics, chemistry, biology, and personal observations.

Libelli are as varied as the libromancers who use them. Most often, an experienced libromancer will have any number of libelli tailored with information for various purposes. Harund, S. (17,234), An Abbreviated History of Libelli, Silval Tower, Grevari Isle: Order of the Gray Watchers
