Aenion

Aenion was one of the sky cities of Titanis. It was identified as a key asset during the Colossus War and destroyed by an Outerfolk flotilla. The battle of Astraea lasted for seven days, and left fragments of titanic and otherfolk technology scattered across Talahaea.
The bulk of Aenion finally fell in what would later become the Dustlands, where the ruins were claimed by the Kingdom of Jackals and their wealth later plundered by the sorcerer Don.
