After a long and arduous mission, Tempest Shadow has finally captured Twilight Sparkle and brought her back to the fallen Canterlot. However, despite having taken the Princess at her lowest point, it seemed that the Alicorn was a bit too tenacious for Tempest's tastes. Not wanting her to try and escape before The Storm King arrives, the mare needed a surefire way to keep her in check. Fortunately, Tempest seemed to find a means to not only ensure Twilight wouldn't leave, but also to show her own power before Canterlot without the Princess even knowing.
