Luke gives a small, sad smile. "It's not entirely like that for Force users. The Dark Side is always there, singing, calling, promising. It's making the choice to keep walking in the Light. I know you don't just 'become' evil, but it was a powerful Jedi who fell and wiped out all the others."

He thinks about it for a moment. "Jedi... is just a code, really. A code to accept and live by, generally taken up by Force users. The Force," he continues, anticipating that question. "The Force is an energy generated and within all the living world. Some beings can sense it and interact with it. I can. My father could."
