Jedi is a profession based on the character of Luke Skywalker. Jedi are individuals that feel a connection to the energy that surrounds all living things and binds the galaxy together, known as the Force. They are, in other words, highly attuned to the flow of the Force. Jedi can, with training, learn to sense and manipulate the Force.
The ultimate rank of a Jedi character is Jedi Master. Jedi Masters are force sensitive beings that can use their powers to overcome and control their enemies and master the art of Lightsaber combat. A Jedi Master may embrace the Light or Dark side of the Force. Jedi may choose to join either the Rebel Alliance or the Galactic Empire.
