This article is about weapon locked away in an Imperial base near Fortress Vader on Mustafar. You may be looking for the archaic lightsaber or the Black Bishop's lightsword.
"Rumors have suggested it to be an incredibly powerful device, something capable of threatening the light of freedom throughout the galaxy."
―Cassian Andor[src]

The proto-saber, known to the Mustafarians as the laser sword, was a type of ancient prototype lightsaber locked away in an Imperial base near Fortress Vader on Mustafar. Sometime between 2 BBY and 0 BBY, members of the Rebel Alliance undertook a mission to Mustafar, and discovered the proto-saber.


The proto-saber functioned differently from the lightsabers used by the Jedi Order during the Clone Wars. Instead of emitting a plasma blade, the proto-saber featured two physical prongs, which rose up from a crossguard. When activated, energy would surge up the prongs and form into a blade between them.[3]


The Rebel Alliance undertook a mission to the planet Mustafar sometime between 2 BBY and 0 BBY.[2] Having gathered intel regarding a dangerous artifact on the planet, Captain Cassian Andor sent a group of agents to a secret Imperial base. There, they recovered their target and discovered that it was the proto-saber. Their pilot, Athex, began to scan the object in order to send it's data to the Alliance. The sword, however, flew out of the agent's hands and into the grasp of Darth Vader, who appeared from the shadows and attacked the rebels. The other agents attempted to give Athex cover fire, but Vader pulled the pilot toward him and stabbed him with his lightsaber. Just before Vader could strike the rest of the rebel operatives down, the reprogrammed security droid K-2SO crashed a shuttle into the building, buying time for the agents to escape. Once in space, the agents transmitted the proto-saber's data to the Rebel Alliance.[3]

Behind the scenesEdit

"That object, we're calling it for now the proto-saber. The idea is it's kind of a prototype of a lightsaber and it may find its way into other mediums, you know, in the Star Wars universe."
Secrets of the Empire writer David S. Goyer in an interview with The Star Wars Show[src]

The proto-saber first appeared in Star Wars: Secrets of the Empire, a hyper-reality experience created by The Void and ILMxLab[4] that opened in Walt Disney World in Orlando, Florida on December 16th, 2017, Disneyland in Anaheim, California on January 5th, 2018, and a limited release in London which ran from December 16th, 2017 to March 10th, 2018.[5]

It was first identified on January 31st, 2018 on The Star Wars Show by Star Wars: Secrets of the Empire writer David S. Goyer. During an interview, Goyer stated, "That object, that we're calling for now the proto-saber, the idea is sort of a prototype of lightsaber and it may find its way into other mediums in the Star Wars universe."[1]
