You spent your youth under the sway of a dread pirate, a ruthless cutthroat who taught you how to survive in a world of sharks and savages. You've indulged in larceny on the high seas and sent more than one deserving soul to a briny grave. Fear and bloodshed are no strangers to you, and you've garnered a somewhat unsavory reputation in many a port town.
No matter where you go, people are afraid of you due to your reputation. When you are in a civilized settlement, you can get away with minor criminal offenses, such as refusing to pay for food at a tavern or breaking down doors at a local shop, since most people will not report your activity to the authorities.
