Ioun the Knowing Mistress is a Goddess of knowledge, skill, magic and prophecy. Sages, seers, and tacticians revere her, as do all who live by their knowledge and mental power. Ioun is the patron of its study. Libraries and wizard academies are built in her name. Her commands are also teachings:
- Seek the perfection of your mind by bringing reason, perception, and emotion into balance with one another.
- Accumulate, preserve, and distribute knowledge in all forms. Pursue education, build libraries, and seek out lost and ancient lore.
- Be watchful at all times for the followers of Vecna, who seek to control knowledge and keep secrets. Oppose their schemes, unmask their secrets, and blind them with the light of truth and reason.
Followers of Ioun are members of the Scribes of Everlasting Knowledge.
