Ioun

Ioun, called the Knowing Mistress and the Lady of Knowledge, is the goddess of knowledge, skill, prophecy, and dreams. Her symbol is a stylized gold eye on a field of purple. She manifests as a dark-skinned woman wearing purple and with a third eye on her forehead.
She is most commonly worshiped in Shan Liang and the eastern reaches of Polnarus. Ioun's followers are devoted to the acquisition and sharing of knowledge. Oftentimes, their temples act as libraries that are open to the public.
