but my very favorite is this one
This is the oldest working single unit lightsaber known to exist. It was wielded by a sadistic Dark Jedi of the Sith in it's golden age. Not only was it used as a lightseptor but as a tool of torture. Nemesis took pleasure in making his enemies writhe in pain before finishing them off. This formidable weapon could be hurled across a room and impale it's unfortunate victim. The second rear activation crystal would activate on impact assuring the kill. Darth Nemeisis' reign of terror came to an end when the Jedi Rodann swiftly ended his life. This artifact now resides in the Jedi Temple as a reminder: the Sith may still be among us.
Rodann is a unique Jedi to say the least. To date, he is the only known of his kind to be of the Jedi Order without the use of the Force. Centuries of training has honed his skills naturally so fine, he has been mistaken for a force user. His skill at building lightsabers is somewhat of an obsession. Never satisfied, his collection of lightsabers are endless. It is rumored he has built and collected hundreds, if not, thousands of lightsabers. A trait some in the Jedi Council frown upon but tolorate. To date, is has not been dertermned if Rodann was lost in the Jedi Purge or went into hidding.
