Agricultural Corps: a branch of the Jedi Order that focused on helping people through cultivating crops. It first appears in "Jedi Apprentice: The Rising Force" by Dave Wolverton (1999).

Archaic Lightsaber: The first lightsabers were created by the Jedi around 15,500 BBY. The blades were dangerously unstable, however, using large amounts of power and tending to overheat. As a result, these early lightsabers served as ceremonial objects rather than weapons. Functional lightsabers were developed after 5000 BBY.
