Steeling herself, Twilight's horn began to shimmer and glow, encased in a magical aura. A single point of purple-white light began to form on its tip, growing in size and intensity. With a small gasp, Twilight let the magic loose and a streak of energy snapped forward like a lightning bolt, arcing between her and the sun, striking it with a blinding flash of light. Twilight was knocked backwards as an explosion of air rippled forward from the gem as a wave of concussive force. She hit the marble floor hard, the breath driven out of her lungs in a violent rush.
