Yasaburō family heirloom lightsaber

The Yasaburō family heirloom lightsaber, also known as the Ancestral Sword, was a green-bladed lightsaber used by the Yasaburō clan on the planet Tao. The lightsaber was brought to Tao by a Jedi who entrusted it to a member of the clan. Before dying, the Jedi trained the clan member to use the lightsaber. The lightsaber became an heirloom and was passed down through the generations of the Yasaburō clan for hundreds of years, eventually coming into the possession of Yasaburō, the clan's leader during the Imperial Era.

Between 12 BBY and 1 BBY, Yasaburō's older daughter, Ochō, joined the Galactic Empire and sided with it against her father. After learning of Ochō's betrayal from his younger adopted daughter, Lop, Yasaburō brought Lop to a shrine in their home, where he explained the lightsaber's history before passing it down to her in a ritual. He then left for Tao's Imperial base to meet with Ochō. After hearing an explosion from the base, Lop rushed there with the lightsaber, where she found Yasaburō and Ochō fighting in a hangar. After Yasaburō was wounded, Lop attempted to persuade Ochō to turn back but was unable to do so. Ochō attacked, and when Lop defended herself with the lightsaber, Ochō became angered, as she believed herself to be the family's successor. They continued to fight, and Lop eventually shattered Ochō's weapon, then slashed her chest. Ochō fell out of the hangar but landed on an ascending starship, which then flew away.
