Paragraph 214, Book 1. The Drauthoring Project.
“A fire dragon,” commented Mog. Damien nodded, sidestepping another swipe from the dragon. “Yes, and so is the other orange one,” he replied. “And the turquoise dragon over there is an electrically powerful one.” Mog frowned. “And the purple one?” he asked. “Do you know what the purple dragon is?” Damien leapt up to avoid another blow from the fire dragon and flapped around, jabbing the dragon in the back of the neck. It swung around and swiped, missing again. Damien paused and shook his head apologetically. “The purple dragon’s still a mystery to me,” he said. “I have no idea.” He was blown from his thoughts by a blast of hot air from the fire dragon, and a stream of fire shortly followed. Damien almost got one of his wings burnt as he dived out of the way.
