During the long war on Cybertron, Sentinel Prime became afraid his planet would die. He wanted to fix things fast. He found a way using space bridge pillars, which could move things across the stars.

So he made a secret deal with Megatron, the leader of the Decepticons. They agreed to cooperate in order to save their house.
The problem was, Megatron wanted power more than peace. Sentinel Prime thought they could work as partners, but Megatron had his own ideas. Sentinel kept his plan hidden and told no one, not even Optimus. When his ship crashed on the moon, everyone thought he was gone. Years later, when he was found and brought back, his true plan was revealed. Sentinel’s decision to turn against the Autobots stunned everyone. In his tale, this was a pivotal time.
