The trailer shows what happened during the last 33 million cycles: the heirs fail to get the coreflames because Cyrene gets spawncamped and Phainon resets the world.
The only reason everything was able to proceed according to the plan was because (You) were there to help.
That's also why Phainon doesn't break down (he just Trianne he's powering through) towards the end when everyone starts dying.
Without the TB:
>Nikador was never defeated, Mydei never became Strife
>Castorice never found Polluxia, she never became Dead
>Subsequently Anaxa never unveiled the truth about Amphoreus and never became Reason
>The raid to the sky fortress never happened, the journey was never even close to completion so battling Aquila was simply never an option
>The time heir never found a fitting substitute.
In the next cycle (spoilers for 3.5)
You enter the cycle as the replacement for Phainon, now your mission is to avoid the death of all the heirs and get the happy ending, (you)re at the helm of the operation, is that not MC enough?
