L is for lightsaber!
So, I said I would update this ASAP, but I didn't. Anywho, here goes:
The lightsaber is an extension of the force wielder that uses it, but it goes beyond even that. A samurai uses his sword as an extension, but a lightsaber becomes a conduit; a conduit of the wielder's combat prowess, and even more so a conduit of the Force. Both Jedi and Sith use lightsabers, as well as some other Force sensitives that are not aligned with either.
