Background
R2-D8 was first commissioned as a support unit for Jedi diplomats. Following the loss of his original master, D8 (or "Date" for short) began communicating using recordings of the deceased Jedi almost exclusively. This has earned him a largely ignored position as the Shipwright under Fenkin Dunway.
Date yearns to explore the Galaxy with another legendary Jedi Master. But he has high standards, nonetheless.
Motivation
Dutybound: The PC has a deep sense of duty that he feels compelled to fulfill, such as military service, making good on a contract, or following some sort of thieves’ code. A Dutybound character has some legal or ritualistic bind to an organization or cause making it extremely difficult or detrimental if he fails to live up to that commitment.
