Koraeleth yawned loudly and stretched himself, getting to his feet from the nook he'd been curled up in, deep in thought.
His siblings had been allowed to get away with far too much lately, he decided, especially as they had not allowed him in on any of their plans. He resolved he should teach them a lesson, put them back in their place. He hadn't had much to do with them over the first ten years of his life, and for good reason, he thought. But it was time to remind them who was the greatest of them, who was the first-born. He padded off through the caves, already running over his plan in his mind. He was truly as curious as the next dragon, and desperately wanted to know just what they had discovered. He knew Mother didn't much like them fighting, but ah well...
What she didn't know, wouldn't hurt her. Besides, someone had to discipline her less-brilliant children. Perhaps she'd even thank him later!
Koraeleth will follow the movements of the three involved in the expedition to the ruined city, when he gets a chance he will confront one of them, preferably the weaker-looking Alterix, somewhere away from Mother, and demand to know where they went and what they found. Any reluctance to speak will be met with a fierce growl of warning, followed naturally by a swipe of his claws...
"What did you find? I know you've been wandering about, without so much as asking me whether you could! Tell me what you saw, and perhaps I shall let you off lightly. Hurry up, before I have to hurt you!"
