- "I found this at the crash site."
"Hm. The lightsaber of Sifo-Dyas it is. Never found when he died it was."
- ―Plo Koon and Yoda
This lightsaber was a blue-bladed weapon that belonged to Jedi Master Sifo-Dyas. Approximately ten years before the Clone Wars, Sifo-Dyas was dispatched by Supreme Chancellor Finis Valorum to negotiate with the Pyke Syndicate on Oba Diah. The Syndicate, on behalf of Count Dooku, shot Sifo-Dyas down, and his ship crashed on a moon of Oba Diah. The ship and the lightsaber were discovered during the Clone Wars by Jedi Master Plo Koon and the 104th Battalion.
