All Spark

History
The All Spark began as a glowing crystal, like the other two Martixes given to Prima by Primus. When Prima was given the All Spark, it was called the Creation Matrix. This was a strong Matrix that could create sparks. This power was too strong for any Cybertronian to hold. Because of this, Prima tasked Solus Prime to create a shell which it could be put in. This shell became a cube that the Thirteen later called, the All Spark. This was because the cube could create life. Solus also made a device that connected the All Spark to the Vector Sigma. This made sure new Cybertronians were made.

When The Fallen tried to conquer Cybertron, he stole the All Spark and planned to obtain both the Matrix of Leadership and Star Saber too. He was stopped by his brothers cast away. After this, the All Spark stayed at its place for years to come.

When the Great Civil War began, Zeta Prime didn't even think of moving the All Spark. This changed though when Sentinel Prime took command. Sentinel sent the All Spark out in space with the hope it wouldn't be found by the Decepticons.

It is unknown where the All Spark went, but Vector Prime had confirmed new Cybertronians were made in the far future. This means at some point, the Cybertronians found the All Spark and returned it home.
