Daughters of the Dark Oracle: Oracle Card Hornbook #1

The Hornbook that you can get with this campaign is an illustrated guide to this first set of cards, and provides a numbering system if you're inclined to keep things in order like I am. There's also a bit of history behind the creation of the concept, easy-to-read instructions on the use of the Oracle Cards, and a few pin-ups here and there. But the main focus is the big enlargements of each card seen on each page of the Hornbook.
