Star Saber

History
The Star Saber was one of three artifacts made by the Thirteen Primes. It was created by the Star Matrix which was given to Prima by Primus. Prima later decided to make shells for all the artifacts. Solus Prime forged a blade which contained the Star Matrix inside it. Prima then gave the sword the name, The Star Saber. Prima wielded the Star Saber along with the Matrix of Leadership. But through time, the sword was lost.

Years later, the sword was found on one of Cybertron's moons by Zeta Prime. Zeta took the sword and directly knew it was the Star Saber. He tried to wield it, but the power of the Star Matrix didn't work. He got to Alpha Trion who explained the Star Saber could only be used by a real Prime. Not a Prime like Zeta was. This angered Zeta. He told Alpha Trion to lock the sword up and never tell anyone about what happened with it.

Alpha Trion's library was later attacked during the Great Civil War. Someone stole the Star Saber, but it was never learned who. It later showed up on the destroyed planet, Planet Q. It was now the Cybertronian, Scorponok found the sword. He kept the sword as he planned to attack Cybertron. It is unknown what happened with this plan after the Ark left Cybertron.

It is believed Optimus Prime would later obtain the sword as it was seen in a vision by Vector Prime.
