So someone had mentioned in another thread that the Staff (Quintessas Staff) isrhe same exact thing as The AllSpark. Seeing the movie now a second time it was clear to me now what the Staff is supposed to be. Quintessa is meant to be more or less, Solus Prime "The Prime of Life". It's clear now that OP IS NOT one of the original 13 or at least that if he is, she lied to him and HE STILL JAS YET TO GET HIS FULL MEMORY back of who or what he used to be. Anyhow back to the Staff. That Staff can re-FORGE Cybertron and started to do so. Vivian now has it. If OP can get Cybertron far enough away from Earth, they can reactivate the Staff and re-forge Cybertron. Seeing that Staff has the power to forge, I don't see why it can re-forge and bring back lost Bots, and or Cons for that matter.
