Tebitnezalrae

The shadow dragon was sealed away inside of Kaz Riley toward the end of the Era of Beginning. The two did not see eye to eye for many years, until Teb came to understand Kaz's motivations and deep compassion. The two eventually formed a deep bond, sacrificing themselves to save the last dragon, a timid bronze.

They were soul trapped in an amethyst gemstone and placed into a ring, known as Shadow Star.
