Lore
Baroness of the Skies. The Pirate Queen. These are just few of many names associated with one of the most formidable evils to soar the sky. Built on reeking havoc upon the kingdoms of Terraria, Avary's ship The Nemesis is a prime example of her sheer wrath and power. Constructed from the salvaged parts of an ancient automation predating most records of life, it was armed to the teeth with deadly weaponry.

It was once said that the those who strive for the highest have the higher to fall. Soon Avery's hubris caught up to her, and one day she chose to make a decision what would lead to her downfall. On the darkest night of the new moon, Avery challenged the Maiden herself.

The battle shook the earth. Avery had the advantage in her small size and agility as well as her deadly arsenal of weaponry. Selene was built in a similar fashion, but slightly more built on raw power. Despite her endurance and tactical mind, she was no match for the Moon Maiden and was subsequently destroyed.
