Slaves and other hard laborers form the bottom rung of many societies in the galaxy. You have somehow managed to escape an unfair existence that put the happiness of your owners over your own life and freedom. You may seek revenge, or just a life of your own out among the stars. Few would begrudge you either, but some see you as a threat to the status quo. To them you are a violation of the order of things. An illegal person, fled from the authorities that once protected you. Though you are on the run, you do have allies. In them you see the redemption of a galaxy that once held you in chains. They see you as more than mere muscle and manners. You are a free being.
Unseen Servant
Through decades of service you’ve learned to make yourself scarce when in the room with the masters. It has to do with how you carry yourself, where your eyes move, and above all keeping silent. When necessary, you can call back to your old life and become one with the scenery. As a bonus action during combat you may choose to become less conspicuous until your next turn. Foes will always target you last while you are “hidden” in this way, generally choosing other targets if there are any other options. This ability also grants you advantage on Stealth checks made to blend into crowds, as you are seen but not noticed.
