Aasterinian is the draconic deity who serves as Io's messenger. Her symbol is a grinning dragon's head. Aasternian appears as a huge brass dragon who is always grinning. She is quick-witted, with a sharp tongue. Aasternian is the messenger of Io, the draconic god of creation. She and her followers enjoy good relations with Garl Glittergold, Fharlanghn, Olidammara and similar deities. Aasterinian loves all those who enjoy innovation and whimsy, and she is accepting of all dragonblooded races. She is especially amused by spellscales.

Aasterinian was first detailed in the Advanced Dungeons & Dragons 2nd edition book Monster Mythology (1992), including details about her priesthood.[1] She appears in Dungeons & Dragons 3rd edition in Defenders of the Faith (2000).[2] Her priesthood and her role as a draconic deity are further detailed in Draconomicon: The Book of Dragons (2003),[3] and in Races of the Dragon (2006).[4]

In Dungeons & Dragons 4th edition, Aasterinian is a mortal blue dragon who has risen to become an exarch of Avandra. Aasterinian's realm of Brassberg can be found on the plane of Ysgard, but Races of the Dragon places her realm in the Outlands instead.[4]
