Jedi

Jedi represent the good side of the Force in the Star Wars continuum.

They are dedicated to helping others and are the opposing number to the Sith.

Making a Jedi engage in a relationship before the creation of the New Jedi Order by Luke Skywalker is a charge.

Origins
According to Wookiepedia, the Jedi began as a Gathering of the Galaxy's best Philosophers, Priests, Scientists, and Warriors on the planet Tython.
