The wolf with whom Fitz forms a Wit bond in the Farseer Trilogy, a relationship that deepens across the sequence into something that defies easy categorisation. Nighteyes is not merely an animal companion but a fully realised presence whose perspective on the human world - pragmatic, unsentimental, and deeply loyal - provides a counterpoint to Fitz's more conflicted consciousness. His relationship with Fitz is one of the most affecting in the sequence and his fate in the Tawny Man Trilogy is among the most discussed moments in the Elderlings universe.
