He sprang out of the nest as if it were on fire. One of the echoes sounded eerily familiar; Thunderclap knew the dragon that was growling and hissing in pain. "Do you know who it is?" he asked, running shoulder-to-shoulder with his sister. "No, but it sounds like..." Lightningtail said as they drew near the crowd. She flapped her wings in the cramped space and peered over the heads. "It is! It's Brisktail! Someone is trying to kill him!" . . .
