When Serah died, her spirit tells Lightning not to give up hope, promising they will meet again. To ensure Serah's memory will live on and preserve the world's existence, she sat on Etro's throne and enters crystal stasis. Waking up 500-years later, she became the savior and fought gods to save the soul of her sister. In the end, the birth of a new world without gods came to be, and all the souls Lightning saved were reborn. - #FinalFantasyXIII #LightningReturns #Lightning #Serah
