Keep in mind that the MacGuffins the heroes involved with this plan involved a time-traveling Primal that locked itself away in a pocket dimension, ancient technology and previously unknown clones from a hyper-advanced society, and a superpowered alien death robot from another world that was likely the strongest thing on Eorzea (until 6.0 comes around).

Furthermore, also keep in mind that Emet-Selch kidnaps G'raha Tia during the lategame BECAUSE he wants to get his hands on the ability to time travel.
