"I'm trained to use what's called a 'lightsaber,' which is basically a blade of pure energy that emits from a hilt," Obi-Wan told him. "It's a traditional Jedi weapon," his eyebrows furrowed a little, "though I saw a droid creature named Grievous who uses one while wandering the halls the other night. If you come across him, I suggest making a retreat if you can."

Then Hughes asked how to identify Force-sensitives, and Obi-Wan quietly smiled at the man's genuine curiosity.

"Trained Jedi can sense when a being is strong in the Force," he explained. "But for more accuracy, we can also perform midi-chlorian tests. Midi-chlorians are microscopic lifeforms that exist in the cells of all living things, and they act as a sort of sensory organ to the Force, like eyes allow us to see and ears allow us to hear. A high midi-chlorian count is usually a sure sign of Force-sensitivity. We generally identify Force-sensitives at a very young age so they can begin their Jedi training as soon as possible, with the family's permission of course."
