From publisher blurb:
This book contains ten tome of lore for the Tyrants of Saggakar setting. These books make great rewards or treasure for players. Some are spellbooks, some are religious, some are travelogues.
It is so much better to receive a copy of a book that has a history than "a nice book worth 5,000gp"
A great resource for the Tyrants of Saggakar, or your own Pathfinder Campaign.
