You recognized the layout of the throne room from the Changeling hive, but without walls or a ceiling. Furthermore, at the end of the room, where the doors would be and you two were currently standing, was a flight of stairs that led down to the front of the royal palace in Canterlot. While usually you'd see a beautiful sight, with a wonderful garden and detailed sculpture, you instead saw fire and rubble, the home of the princesses falling apart, while numerous ponies lay in defeat or death.
