Story challenge: Time travel
In many other fandoms, stories exist where the protagonist of a story travels back in time to a certain point in the story. My challenge is thus: What would Yuri do if he went back in time to the beginning or some other point in time? Perhaps he'd scare Nia off before she could function as his launcher or something. Are the Overlords and their Phages affected by the reversal? And if not, are they immediately attacking or will they hold off for some reason?
As for the mechanics of time travel: Remember that it is stated in game that flux sectors can erase someone completely from existence, and therefore can effect time along with space as otherwise evidence of a persons effect on the universe can't be completely erased.
