Councillor Clarette is the most powerful Polyglot in the Lost Cities. She has the ability to talk to animals, which most Polyglots do not. She is also a Councillor, but not much else is known about her. She is encountered in Book 4: Neverseen when threatening the Black Swan with Arthropleura. She seems to genuinely care about animals because she soothes an Arthropleura after its antennae breaks off, impaling Fitz. She is also one of the first councillors to agree with setting the alicorns free. Her throne is said to be covered with animal faces.
Councillor Clarette has bronze skin and silky black hair. Sophie describes her as reminding her of a volcano goddess.
