It's been three years since Toolsmith was caught. Physical and mental wounds were healed, and Equestria seems to come back to normal. Twilight works as a librarian, Rainbow Dash becomes a Wonderbolt, and Vinyl Scratch gets mugged in Detrot by a suspiciously familiar-looking mare... who looks for the new victims.
