The Dravione aeries was a location on Dravione.
Bleys Harand visited them in the hopes of finding an accurate representation of the face of Xim the Despot and was told of a statue of Xim there. However, he found the courtyards empty but for a ruined statue that was missing everything above the calves. He recorded his journey in Travels Amid Strange Stars.[1]
