The messenger god of dragons, who serves Io as a herald and vision-bringer. When she is not delivering visions and messages, she lives in a small set of caverns deep within the Realm of Nidavellir. The caverns are just large enough to contain Aasterinian's hoard. Any trespassers are usually devoured immediately, unless they happen to be amusing, and they are allowed to leave with their lives. She also particularly enjoys the many inventions of Norse Dwarves, and her avatar will sometimes walk among them in the guise of a dwarf. Aasternian is on good relations with Garl Glittergold, Fharlanghn, Olidammara and similar deities.
