The Black Rose Has Thorns

Ruby Rose is the daughter of Qrow Branwen and Summer Rose. I know Qrow is actually mentioned as her uncle in RWBY but I believe he was only mentioned to be her uncle because of his semblance for bad luck. Anyway, this story is fairly different. Here, Ruby actually joined Salem in order to protect her friends but it doesn't work out the way she wanted and it's already too late to save her friends along with the rest of Remnant when Salem made her evil the way she made herself evil from the pool of grimm. Can her friends save her in time to end Salem once and for all?
