The Kyber Saber, an ancient Jedi artifact, was crafted by Baird Kantoo and later unearthed by Rowan Freemaker.
Forged from numerous pure kyber crystals, the Kyber Saber possessed immense power. Capable of obliterating a rock and subsequently a moon, its creator, recognizing its danger, shattered it and scattered the crystals across the galaxy. This particular lightsaber exists exclusively in Lego form; no other replicas are available.
Prior to the rise of the Old Republic, a Jedi Master named Baird Kantoo constructed a sword from pure blue kyber crystals, which became known as the Kyber Saber. Considered the first lightsaber, legend stated that the Kyber Saber amplified the wielder's Force abilities a thousand times. Wielding it, Kantoo discovered its potential for creative reshaping of landscapes and destructive annihilation of entire planets with a single strike. Realizing its excessive danger, the Jedi Master destroyed the weapon and concealed the crystals throughout the galaxy.
During the Galactic Civil War, the Sith Lords Darth Sidious and Darth Vader discovered the existence of the Kyber Saber within the Jedi archives and resolved to acquire it. Darth Sidious immediately wanted to collect all the Kyber Crystals and use them to destroy the galaxy in one big blast. The Sith Lords dispatched the Sith agent Naare to recover the fragments of the Kyber Saber. Naare journeyed to the jungle planet of Nal Kapok, where she located the first Kyber Saber crystal still embedded in its original hilt within an underground cave. During her expedition, she encountered a Force-sensitive boy named Rowan Freemaker and his B1-series battle droid Roger, rescuing them from a dianoga. Naare successfully convinced Rowan that she was a survivor of the Great Jedi Purge. After sharing the history of the Kyber Saber, she earned Rowan's trust and offered to train him in the Jedi arts. Subsequently, Naare settled with the Freemakers at the Wheel space station, deceiving the owner into renting her a room for a single credit.
Later, Rowan sensed through the Force that the second Kyber Saber crystal resided within the Belgaroth asteroid field. While Naare and his older sister Kordi Freemaker debated Rowan's safety, Rowan and Roger secretly departed on a ship for the Belgaroth asteroid field. There, they discovered the second kyber crystal embedded in a rock above a lava vat. Despite retrieving the crystal, they were promptly captured by the Hutt crime lord/expert miner Graballa, who coveted the crystal. Rowan's older brother Zander and sister Kordi launched a rescue mission with Naare's assistance. During their escape from Graballa's base, the kyber crystal was ejected into space. After evading Graballa and his henchmen, including the bounty hunter Dengar, Naare, enraged by the Freemakers, attempted to destroy their starship, the StarScavenger. However, Rowan sensed the second crystal and successfully retrieved it, earning Naare's praise.
Following a false lead on Cloud City, (for nothing but Lando's cape) Rowan managed to acquire the third Kyber Saber crystal from a Trandoshan statue on the Wookiee homeworld of Kashyyyk. Rowan's discovery pleased his "master" Naare. Despite these initial successes, Naare soon faced delays in her mission to recover the remaining kyber crystals due to the Freemakers' preoccupation with other matters. Growing impatient, the Emperor suggested, via hologram message, that Naare harm Rowan's family to motivate the boy. Rowan inadvertently discovered the message and realized Naare's Sith affiliation.
Rowan informed Kordi, Zander, and Roger, and the Freemakers fled their garage (Freemaker Salvage and Repair) on the Wheel. After escaping Naare, the Freemakers decided to locate the remaining Kyber Saber crystals to prevent the Empire from using them for destructive purposes. On Takodana, Rowan successfully obtained the fourth Kyber Saber crystal from Maz Kanata. However, Naare allied with Graballa, who desired the crystals to fund a beachside resort and buffet. To capture Rowan, they agreed to share the crystals. With the assistance of Graballa's starship Rancor's Fist, Naare managed to steal the fourth, fifth, and sixth Kyber Saber crystals from the Freemakers on Takodana, Ningoth, and Naboo. Despite losing Rowan, Naare tracked the Freemakers' movements using a tracking device planted on Roger's bagpack.
After learning that the seventh Kyber Saber crystal was on the frozen planet of Hoth, the Freemakers delayed Naare by seeking refuge with the former Sith clone Jek-14 on the planet Zoh. When Naare and Graballa discovered their location, the Freemakers raced their opponents to Hoth. There, Rowan and his siblings discovered the last Kyber Saber crystal hidden in an underground ice cavern. After recovering the final crystal, they engaged Naare and Graballa in a brief battle. Ultimately, Rowan tricked Naare by offering her a fake ice shard. Before Naare and Graballa realized the deception, the Freemakers escaped offworld on the StarScavenger. Following their Hoth adventure, Rowan, fearing for his siblings' safety, secretly departed with Roger on a Z-wing (one of Zanders uglies, as Kordi reffered to them as) the Mini Scavenger and fled into hyperspace.
Rowan and Roger concealed themselves and the last Kyber Saber crystal on an uncharted planet. There, Rowan completed his Jedi training with Roger's memories and training droids. Meanwhile, Naare devised a plan to lure Rowan out of hiding by torturing Zander and Kordi. Naare destroyed Zander's starship collection and Kordi's credits, inflicting emotional distress. Sensing their pain through the Force, Rowan returned with Roger to confront Naare. Despite defeating Naare and Graballa's henchmen in a fierce skirmish, Naare learned that Roger knew the location of the last crystal. After stealing the droid's head, she terminated her deal with Graballa and used her Force powers to drive him out. Naare then departed on her Eclipse Fighter to retrieve the seventh crystal.
Using the information stored in Roger's databank, Naare traveled to the uncharted world and reclaimed the seventh Kyber Saber crystal. After reassembling the Kyber Saber, Naare was contacted by the Emperor, who expressed anger that his servant was handling his "prized weapon." Tired of serving the troublesome Sith Lord, Naare rebelled and used the Kyber Saber to destroy an Imperial fleet above Coruscant. Having decimated Palpatine's defenses, Naare attempted to declare herself Empress. During the fighting on Coruscant, Rowan and the other Freemakers managed to steal back the Kyber Saber. Despite being pursued by Imperial forces, the Freemakers escaped into hyperspace. Aware of the Kyber Saber's danger, Rowan decided to destroy the weapon by throwing it into the lava fields of Sullust.
Palpatine, enraged by the theft of the Kyber Saber, placed Rowan on the Empire's 27th Most Wanted List. Meanwhile, Graballa and his henchmen caught up with Naare and had her frozen in carbonite as punishment for breaking their deal. In space, the Freemakers joined the Rebel Alliance at the invitation of Admiral Ackbar, who had learnt of Rowan's exploits.
Without knowledge of the Kyber Saber's destruction, the Emperor created the hunter droid M-OC and tasked him with capturing Rowan Freemaker and recovering the lightsaber. M-OC succeeded in capturing Rowan, but Darth Vader, his rival, incapacitated M-OC and brought the boy to the Emperor.
In captivity, Rowan revealed that he had destroyed the Kyber Saber. While the Emperor was furious, Lord Vader convinced the Emperor that they could use Rowan's Force powers to find more kyber crystals for the second Death Star.
Despite believing he had destroyed the Kyber Saber, Rowan discovered he could still sense the crystals and retrieved them from Sullust. During the Battle of Endor, Rowan used the Kyber Saber (somehow getting them out of the lava) to defeat M-OC, who was guarding the main reactor on the second Death Star. It was destroyed once and for all when Rowan plunged the Kyber Saber into the giant kyber crystal that M-OC had salvaged from the wrecked Arrowhead. The two crystal devices exploded, destroying M-OC. Rowan survived the explosion and was later evacuated by the StarScavenger.
The Kyber Saber made its debut in the first season of the Disney XD animated series LEGO Star Wars: The Freemaker Adventures, which aired between June 20 and August 29, 2016. The Saber briefly reappeared in the Season Two finale episode "Return of the Return of the Jedi," which premiered on August 16, 2017.
