Severian

Severian is the narrator and main character of Gene Wolfe's four-volume science fiction series The Book of the New Sun, as well as its sequel, The Urth of the New Sun. He is a Journeyman of the Seekers for Truth and Penitence (a Guild of torturers) who is exiled after showing mercy to one of his clients.

Severian claims to have perfect memory (his eidetic memory is stated as a fact by Gene Wolfe in Shadows of the New Sun). In spite of this, some critics and analysis claim him to be an unreliable narrator.
