Pure Blooded Thief

A pure blooded thief infiltrates a criminal airship in a government mission. While the goal is to get incriminating files, a pure blooded thief will go for something priceless instead, and the government will realize they've gone rogue and they are not pardoned. This will either lead to joining the criminal organization, being pardoned much later, stealing a base and converting it into a resort, or stealing another priceless object.
