A Nightmare Dragon is believed to not be a true, living creature at all, but an entity composed of pure magic, created from wild currents of Amethyst Magic that have taken on the semblance of life. Their breath weapon is akin to that of a Black Dragon's, in the form of a noxious gas that can wither the lungs of its victims and rot their flesh, only more potent.[1a]
