Meanwhile, Karth busied himself by counting his treasure, of course, he wouldn't be able to count it all in a reasonable amount of time, so he satisfied himself by looking to make sure that everything looked unnoticeably disturbed at the very least, and he decided to actually count the stuff later, when he had more time on his hands. 

The human he had absconded with was sobbing, and the noise was very distracting. He lumbered out of his treasure-horde to peer over at his sobbing dinner.

"You. Human. Answer me this riddle. A poor man has me, and a rich man needs me, but if you eat me, you will die. What am I?" The great dragon asked. It was a simple riddle, but perhaps it would keep the human busy enough to stop that insufferable noise she was making.
