This is a continuation from the ending of Final Fantasy XIII-2. All you need to know about the story to enjoy this piece is that Lightning is the heroine, her mission is to stop Caius, who is the villain, but she is defeated by him and transforms herself into crystal. A bit more information is provided in the first comment.
A crystallized woman sat cross-legged on the throne, adorned with silvery armor, her sword resting on her lap. Caius stared at his nemesis, they had engaged in an endless battle in which he had emerged victorious. “You cannot escape from me, Lightning”, Caius said, dispelling the magical crystal.
The crystal returned to flesh. Lightning opened her eyes, awaking from her stasis, and was immediately confronted by Caius, the man who had defeated her and destroyed the world. The Goddess had granted her great powers to stop Caius but she failed. “I wasn't hiding from you,” she scowled while trying to disguise her shame, “What do you want?”
“I have already won. Now I have come at last to take you,” he gloated confidently.
“I will never give in to you, monster,” she replied, clearly taken aback by Caius' directness.
