RWBYverse ( A sequel to this is what you came for)

This is a sequel to my other book "This is what you came for (Undertale reader x RWBY)": It's been a few years since Error's attack and everyone is saddened by the disappearance of Ruby and her new friends she made and only WBY know what happened but as the Battle of Beacon had begun some old faces pop up and tell them a threat greater than Error or Salem.
