During the period when Cere Junda was apart from the Stinger Mantis crew -- a period of five years -- she built a new lightsaber with a blue blade. This weapon served as a replacement for her previous lightsaber; she had sold the kyber crystal from that older lightsaber to assist Greez Dritus in settling his debts with the Haxion Brood, and she had gifted the hilt to Cal Kestis, so he could utilize its components to craft a new lightsaber.
Junda engaged in combat with the Fifth Brother on Murkhana, wielding this very lightsaber.
She possessed this lightsaber as she aided the clandestine organization known as the Hidden Path. This network was dedicated to smuggling Jedi, other Force-sensitives, and their allies away from the reach of the Galactic Empire, ensuring their safety.
While attempting to protect her Archive on the desert moon Jedha, Junda engaged in a duel with the Sith Lord Darth Vader, using this saber. This confrontation ultimately led to Junda's death. Cal later retrieved the lightsaber, along with Junda's remains, and interred them together on the secluded planet Tanalorr.
