so i have heard that this fanart here is based on a fanfic that Fate is turned into a cyborg and lost her senses, fought Nanoha and in the end she came back to her senses and blocked a blind attack for Nanoha. Another one is that Fate protected Nanoha and lost (blind) her left eye that's why it's painted yellow. Could anyone pls tell me the name of the fanfic, i'm desperated to know.
