Laeva was a prismatic dragon who abused her increased magical heritage and genetic leg up to study and master forbidden magicks, most notably the power to dominate another's soul so completely that they in essence become a copy of her. As punishment, her soul was sealed in a spherical prison, in turn sealed deep underground. Freed by a dark deity, now known simply as 'The Watcher', Laeva seeks a new host body that will be able to contain all of her power while offering room for growth, content to possess others by chaining herself up to them for the time being.
