FINAL FANTASY XIII-2 PROLOGUE
She defied her destiny. She set out to vanquish the false gods enslaving mankind.
After the war, the world was no longer the same. Humans reigned victorious and their gods were no more. Their utopia fell from the sky and became one with Pulse, the underworld crawling with beasts and fiends. It marked the beginning of a new era.
However, she was nowhere to be seen. Everyone believed she was gone—with the exception of one, her sister, Serah.
Three years later—
A meteorite disrupts the serenity of a peaceful village. Time is distorted; bloodthirsty monsters are released within the confines of the secluded town.
Amidst the chaos, Serah is saved by a stranger who goes by the name of Noel. A hunter from the future, he bears an important message.
“She is waiting for you,” he says. “Come with me if you want to see her again.”
She is Lightning—protector of the goddess who rules the realm of death and chaos, the one-and-only sister of Serah.
“I need to see her. I need to see my sister.”
Her heart brimming with hope, a determined Serah sets off on an adventure to reunite with her sister, her family, her world.
