Pirate Apprentice

A Pirate Apprentice is an individual who resides on a pirate ship in order to learn the ways of piracy from more experienced pirates.

Role and Duties
Pirate apprentices are members of a pirate crew that possess the least authority on a ship, since their main purpose is to learn how to become a proper pirate. Their training involves partaking in habitual pirate activities such as raiding other ships.

Once an apprentice is fully educated, either they become full-fledged members of their crew or leave it to become captains of their own crews.
