Luna pulled herself back to her hooves. There might still have been ponies trapped in the city, and she didn't have the time to sit around and daydream. She spread her wings and took off, searching for signs of fighting, of which there seemed to be less and less. The city had almost become unbearably quiet as the Equestrians retreated, and Luna hoped that meant there were no others to save and she could leave herself. Faust was likely looking for her, so, given the lack of much else to do, she turned to leave, and only just spotted the flash of magic out of the corner of her eye towards the outskirts of the city.
