Origin[edit | edit source]
In the time before the Dawn War, Ioun's dominon 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.
Publication history[edit | edit source]
D&D 4th edition[edit | edit source]
Ioun first appeared as one of the deities described in the Player's Handbook (4e) (2008).
Creative origins[edit | edit source]
Ioun's name originates from the ioun stone, a popular Dungeons & Dragons magic item first introduced in The Strategic Review #4 (Winter 1975). In turn, the ioun stone originally appeared in Jack Vance's short story Morreion, published in the fantasy anthology Flashing Swords! #1 (1973) and later collected in Vance's anthology Rhialto the Marvellous (1984).
According to the editorial to Dragon #405 (Nov 2011), writer Christopher Perkins made the decision to take the name Ioun for D&D 4th edition's new god of knowledge. D&D 4th edition would retcon this deity to be the namesake and creator of the ioun stone. The AD&D 2nd edition Forgotten Realms lore previously had established a human mage named Congenio Ioun as creator of the ioun stones. No canonical link between Congenio Ioun and the goddess Ioun is known.
