Perhaps one of the most distinctive weapons in the entire universe, the lightsaber is the weapon of choice of the Jedi and the Sith. First created around 25,000 BBY (Before Battle of Yavin), the lightsaber has seen a variety of different designs and modifications, and no two lightsabers are the same.
The lightsaber consists of a metal hilt which projects a beam of plasma energy. This plasma is contained within a force field which protects the user from the intense heat given off by the plasma. The majority of lightsabers are powered by a diatium power cell, an incredibly powerful source of energy which is able to indefinitely recharge itself. The color of a lightsaber can be attributed to the lightsaber crystal housed within the hilt. Most crystals are blue or green, but different crystals can be combined to create a variety of different colors.
