Luna listened to her hoofsteps die away until the sound spell cancelled them out altogether as her sister crossed the threshold. Luna sat there for some time afterwards, nothing making a sound in her sanctuary other than the sound of grains of sand ticking away the time in an hourglass somewhere high above her. She looked at the notes she had been making, useless scribbles going over and over the first-hoof account her guard had given her. Old magic – exactly what was that supposed to refer to? Dark magic? That was old, but she had never heard it being referred to in that manner. And the pony had targeted the human's unicorn servant, if she recalled, the one reported to have been harassing him in the streets while he was in Canterlot, whatever that had been over.
