All dragons have hoarder tendencies. Azrah has put hers towards, of all things, pillows and cushions. Because if you're going to sleep on a hoard, you might as well be comfy.
Soul Blast is a devastating spell that releases all of the magical energy in her body in one massive burst. Extremely powerful, but with a high cost; Azrah can't concentrate the energy like this, and doing so completely drains her.
