Transformers: The Last Knight (2017) Timeline Explained – Every Event in Order

Optimus Prime is manipulated by Quintessa, a sorceress who claims to be his creator. She convinces him that Cybertron is dying and that Earth (revealed as Unicron) must be destroyed to save his home world. Under her control, Optimus is renamed Nemesis Prime and sent to retrieve the Staff of Merlin.

Foreshadowing: Quintessa's manipulation is foreshadowed by her claim to be Optimus's creator, which gives her psychological leverage over him.

In 484 AD, Merlin forged an alliance with the Knights of Iacon, twelve Transformers hidden on Earth. They bestowed upon him an alien staff and transformed into a dragon to help King Arthur battle the Saxons. The staff was buried with Merlin, fused with his DNA, making it only wieldable by his descendants.

Quintessa reveals that Earth is actually Unicron, Cybertron's ancient nemesis. She plans to siphon Earth's life force to restore Cybertron, which is disintegrating. This twist connects the planet to the Transformers mythology as an ancient enemy.

William Lennox, a TRF member, brokers a deal with Megatron to release Decepticons to capture Cade and retrieve the talisman. He discloses Cade's whereabouts, hoping the U.S. military would intervene during the chaos.

The Staff of Merlin is a powerful alien weapon given to Merlin by the Knights of Iacon in 484 AD. It was stolen from Quintessa, who created Cybertron.
