Samuro

Samuro was a Jedi Knight who lived centuries before the onset of the Clone Wars. He recognized the threat posed by the energy vampire Countess Rajine and imprisoned her and the victims of her life-draining powers on a remote world. Samuro used the Force to raise a barrier over the world, sacrificing himself to ensure that Rajine and her victims could not leave the planet. Sometime before his death, Samuro recorded a message for Rajine in his Jedi holocron and instructed his droid, Z-18, to give it to the Jedi who would eventually arrive on the world.

Centuries later, during the Clone Wars, the Jedi Master Mace Windu arrived on Rajine's world. After Windu was captured and imprisoned by Rajine, Z-18 freed the newly arrived Jedi and gave him Samuro's holocron. Once Windu confronted Rajine and activated the holocron, Samuro's image and Windu recited an incantation that freed the life-forces of Rajine's zombies. The victims then turned against the countess and killed her.
