"This lightsaber was stolen from your Jedi Temple by my ancestors during the fall of the Old Republic."

- Pre Vizsla

Pre Clone Wars
Thousands of years before the Clone Wars, the lightsaber belonged to one of the Jedi of the Jedi Temple on Coruscant. The weapon was then stolen by Pre Vizsla's ancestors and was passed down from generation to generation, eventually falling into his possession.

Clone Wars
During the Clone Wars, Obi-Wan Kenobi would arrive to Mandalore to investigate rumors of conspiracy surrounding Duchess Satine. Vizsla would then fight Kenobi during his stay on Mandalore. Before the battle, Vizsla activated the lightsaber, revealing a black blade, and remarked to Kenobi that the weapon had been stolen by his ancestors during the fall of the Old Republic, and that it had been passed down generation to generation, eventually falling into his possession. The two would then engage in a lightsaber duel while Duchess Satine and Vizsla's men watched from afar.
