Metis was the child
Seitou and
Kaliforna, the two leaders of Raven Hallow, that they kept. As the clan's unique form of worship by showing devotion to their deity and dragonkind by breeding new dragons, it was unique that they kept any of their hatchlings.
Over the course of years, Metis slowly lost faith in her parents and believed that a new regime was in order. A feeling that was shared and made stronger by her friendship with
Vornz. It was also a feeling that she hid from the majority of the clan.
But her icy heart eventually bled into some of her hatchlings. Those of her hatchlings that were affected became unhappy with any form of hierarchy and tended to live solitary lives.
