The lightsaber is the weapon of a Jedi, an elegant weapon of a more civilized age. It can be used to cut through blast doors or enemies alike. Using the Force, a Jedi can predict and deflect incoming blaster bolts, and reflect them.
An ancient, honored heritage within the hallowed halls of the Jedi Temple was the role of the Jedi Temple Guard. Reporting to Cin Drallig, head of security, the Temple Guards were anonymous sentinels plucked from the ranks of the Jedi as part of a Knight's ongoing commitment to the Order. A Jedi Temple Guard would disappear inside the formal robes and identity-concealing masks, the ultimate expression of emotional detachment required in service to a higher calling. Temple Guards carried imposing lightsaber pikes -- thick, double-bladed weapons that produced a rare and distinctive yellow blade.
At the heart of every Jedi lightsaber is a kyber crystal found on several planets, most notably the icebound caves of Ilum. This crystal is attuned to the Force, and connected to a Jedi Knight on a deeply personal level. In this way, a lightsaber is an extension of a Jedi's Force awareness. Because Jedi let the Force guide their selection of the crystal, the vibration that the crystal creates in the lightsaber blade helps Jedi center themselves and find balance in the Force. In this way, a Jedi can center his or her attention beyond the distractions of combat. A lightsaber crystal is colorless until first attuned and connected to a Jedi -- at which times it glows either blue or green, or in some rare instances, another shade. From that point on, it retains that hue.
A noble order of protectors unified by their ability to tap into the power of the Force, the Jedi Order were the guardians of peace and justice in the Galactic Republic. The age of the Jedi would end, however, due to a nefarious plot by the Sith Lord Darth Sidious.
Instantly recognizable by its distinctive crown of five spires, the Jedi Temple was the home of the Jedi Order on Coruscant. Part school and part monastery, the Jedi Temple is the central hub for all Jedi activities around the galaxy.
