Luna bent her head to examine the magical residue. It was...haunting. Something about it seemed familiar. It teased and danced at the edges of her senses but at the same time a part of her mind rose up to block it out. She shook her head as if in pain, trying to think through the sudden pounding that had erupted in her head.<br/><br/>Dusk could see that the black traces of magic formed a semi-circle around the valley. It started where the grass withered, entered the valley, then darted to the right and made a shallow crescent before charging right at the silo. Then it became a cloyingly thick knot around the silo and the guard ponies. But if she strained, she could just make out a tiny trail of magic, black hoofprints in the withered grass, leading behind the silo and away into the distance.
