A mid-ranking Servant whose fanatical devotion to the organisation's mission and whose particular cruelty toward those she considers threats make her one of the Fitz and the Fool trilogy's most immediately threatening antagonists. Dwalia's pursuit of Bee is the driving engine of much of the trilogy's plot, and her absolute certainty in her own righteousness gives her a particular quality of menace - she is dangerous precisely because she believes completely in what she is doing.

A Servant with an unusual ability to compel others' compliance, whose relationship with Dwalia is one of dependency and fear rather than genuine loyalty. Vindeliar's arc across the Fitz and the Fool trilogy is one of its more surprising - a character introduced as a straightforward threat who develops unexpected complexity as his circumstances change. His interactions with Bee are among the trilogy's most carefully observed examinations of power and vulnerability.
