Ioun is the goddess of knowledge, prophecy and skill, and is a patron of the study of magic and mental power. Sages, seers, and tacticians revere her, as do all who live by their knowledge and mental prowess. Corellon is the patron of arcane magic, but Ioun is the patron of its study. Libraries and wizard acadamies are built in her name.
Ioun’s holy symbols are an eye open to observation and watchfulness, and a book of knowledge. They are commonly depicted together, with the eye emblazoned on the book.
Ioun teaches her followers thus:
- 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. Information is to be shared, not hoarded.
- 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.
In addition to books of her teachings, followers believe that Ioun speaks through omens, portents, and signs, but these are often subtle, brief, and easily overlooked. A candle or light source appearing in what would otherwise be a dark place is considered one of her most common signs to believers. Portents may also come in the form of a specific book or scroll dropping into a person’s hand at an opportune moment, or a book opening to precisely the desired passage.
The priests of Ioun also believe that the goddess sometimes reveals the future through prophets or other worthy individuals. These prophets receive messages through dreams or waking visions. Sometimes images in water or mirrors are messages from the goddess, revealing insights or warnings.
The worship of Ioun is common throughout civilized places in the Free Kingdoms. Ioun is worshiped by all those who thrive on the power of their mind: wizards and seers, of course, but also scholars, lawyers, architects, and even military strategists. Ioun is the second most popular deity among metallic dragons, second only to Bahamut.
Ioun’s tend to be clean, simple, and well-designed, with a focus on learning and knowledge over liturgy and ceremony. Every temple to Ioun, large or small, contains a library. Many of Ioun’s temples serve primarily as large public libraries or universities, open to all who respect knowledge. Any place where learning is revered is considered sacred to a devotee of Ioun.
In the time before the Dawn War, Ioun’s dominion in the Astral Sea was a vast lagoon, surrounded by beaches of white sand, used by the goddess as a scrying pool. When the conflict between the gods and the primordials erupted, Ioun fused her dominion with those of Erathis and Pelor, forming the Bright City of Hestavar. After the war, Ioun relinquished her rule of Hestavar and retreated into the Hall of Enlightenment at the Swan Tower of Kerith-Ald.
Ioun is an ally of Corelllon, Erathis, and Pelor. She is the antithesis of Vecna, the God of Secrets, and she urges her followers to reveal his cultists whenever possible in order to share all knowledge that he would keep hidden.
