Ioun

Ioun is the unaligned goddess of knowledge, prophecy and skill, and is a patron of the study of magic and mental power. She is revered by wizards, scholars and tacticians.

History
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 Ioun as a scrying pool. As 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. The primordial Heur-Ket lay siege to the city shortly after. After the war, Ioun relinquished her rule of Hestavar and retreated into the Hall of Enlightenment at the Swan Tower of Kerith-Ald.

Relations
Ioun is an ally of Corellon, Erathis and Pelor. She is the antithesis of Vecna, as she urges her followers to share all knowledge that he would keep hidden.

Temples
A major temple resides within a wing of the Grand Academy in Ryth that dedicated to Ioun and Corellon.
