Seath

Seath was taken in as a scholar. Her original form is different, her original name is different, but in her studies she discovered a powerful magic based on crystals.
Her studies revealed a mythical figure, a pale drake of incredible power, and as she dived deep into study she began to emulate this mad Duke of a forgotten land. She changed her breed to match his supposed shape, she changed her primary coloration to match his, she changed aspects of her own essence in order to surround herself in crystal blue motes, and her research allowed her to transmute her wings into sheets of blue crystal.
She was relieved of duty, and the clan watches over her, allows her to heal, aids in her recovery. But the scars of her research are evident, and the location of the archive she studied is lost.
Perhaps for the better.
