After the six l'Cie manage to destroy Orphan and save their two worlds, Fang and Vanille fuse into a crystal pillar, while the remaining four reunite with family and friends. Some time after, Lightning is pulled into Valhalla, a realm once held by the goddess Etro, to become Her knight. She is locked in battle with a vengeful Caius Ballad, who seeks answers as to why his charge is dying again and again across all time. Caius' attempts to save Paddra Nsu-Yeul have, unfortunately, created a massive series of temporal rips, altering the history of Gran Pulse over the hundreds of years since Ragnarok and potentially leading to the end of the world. In an effort to mend the now-tattered fabric of time, Lightning reaches out to Noel Kreiss, the last survivor of a collapsing humanity, and tasks him with finding her sister Serah, in order that the pair may succeed where she has yet to.
