The Book of Ioun
A Powerful Relic of Ioun
The Book of Ioun is a huge (3’ by 2’) book made of slightly-shimmering vellum, with a heavy board cover. When opened, one must only think of the passage one wishes to read, and the book always opens to that page.
When written in using a ceremonial pen using ink of residuum, in a ritual conducted as the first star lights the night sky, one may ask a question to the god of knowledge, who will then write the answer on the next page.
