Dynasty of Primes

In Transformers: Revenge of the Fallen, the Thirteen original Transformers were replaced by seven characters referred to as the Dynasty of Primes, scattered throughout the galaxy looking for planets where they could build Sun Harvesters. These Sun Harvesters, powered by the Matrix of Leadership, were capable of harvesting a sun's energy to produce Energon. The Dynasty of Primes had only one rule: Sun Harvesters were not to be built, let alone use, on worlds containing life.

Transformers Revenge of the Fallen
The Fallen, ignored his brother's rule and arrived on Earth 17,000 BC and started building a new Sun Harvester with other Cybertronians. This resulted in the war between the Autobots and Decepticons. The Autobots fought for the humans survival, along with there planet while the Decepticons fought for the Energon. This war ended with the Autobots defeating the Decepticons and The Fallen being imprisoned by the Dynasty of Primes as they sacrificed themselves to seal the Matrix by making a cage of their own bodies to seal it. Only a Prime can defeat The Fallen, and there's only one left, Optimus Prime.

Also, when Sam temporarily dies, he sees a vision of the Dynasty and they tell him he has earned the Matrix for his courage and his determination to save Optimus and reveal that this was always his destiny. The Dynasty then resurrects Sam and re-create the Matrix back into it's solid form, which Sam uses to resurrect Optimus.
