Twilight becomes alicorn of the stars. This is sort of a problem, because Luna kind of already was alicorn of the stars. Oops!

TV Tropes

During her duel With FN-2187 onboard the supremacy in which she was supposed to fall to her death, she falls into the land of Equestria, full of happy friendship loving ponies, ones that are not violent. All things which are almost polar opposites of Phasma.

Takes place during S4 but before the episode Pinkie Pride.
