My OC, Harmony, is supposed to be a crossover of Star Wars and MLP, my two favorite things (besides sugar, of course.). She, however, also has unicorn magic, so those two powers collided, and soon, Sithmony was born. She was assumed by Harmony as an imaginary friend from foalhood, but Sithmony eventually started to take over Harmony. They were locked in a mental battle for half a year until Harmony had enough. She cast a spell that split them apart, and Sithmony ran off to join the Siths, having a lot of knowledge about the Ghost crew, and Harmony realized what she had done. Since then, Harmony and Ezra have been hunting her down, trying to find a way to defeat her.
Yes, I know I had messed up on the symbols on the heart, but I did my best. Don't judge! Also, the 'clouds' are supposed to be mist. Harmony is just dreaming this. I mean, when this is happening, Sithmony is still just part of Harmony. Credits to seabreezedalek9
