The Sword Maidens are a pirate group that used to hold considerable power and influence in Frontier under Lydia. They call themselves the Daughters of the Frontier. All Sword-maidens have a sword made from the most exotic materials and are known to be so sharp they can even cut steel.
They are typically known to have gene improvements courtesy of the Blackmarkets in the Frontier, that made them stronger than a baseline human in the Frontier.
Under Lydia, they grew to be a formidable group and known for their reputation for being ruthless.
