In order to take this trait you must have the Teaching skill at Trained or higher.
You have an Apprentice, someone who is attempting to become the same or similar Occupation. This Apprentice is created and controlled by the GM, but you have the ultimate say on their personality, backstory, and overall character. This Apprentice receives all of the skills from their Occupation they're attempting to become (excluding the Apprentice Rank skills), but all of them are at Apprentice Rank.
