Amithy is an older woman with sharp, severe features: a tight bun, a harsh face, and long, bony fingers.
Her personality is well-represented by her looks: she is strict, cold-hearted, and rigid.
Throne of Glass
Heir of Fire
She frequently antagonizes Sorscha for a variety of things, from her work to her looks. Amithy scolds Sorscha after discovering the mess - which, unbeknownst to Amithy, Prince Dorian caused - in Sorscha's workroom, then reminds her that healers are not to consort with their patients outside of their duties. Near the end of the novel, Amithy betrays Sorscha to the king. She fetches Dorian and Sorscha both, telling them that the king wants to see them both in his chambers. She goes with them and looks on as the scene unfolds.
