He is described as being a sinewy warrior with a dark face, an aquiline nose and very white teeth.
Unlike the books, in The Hexer TV series, Eist died soon after his marriage to Calanthe, before the Nilfgaard invasion.
He was played by actor Jerzy Piwowarczyk in the movie and TV series.
- Originally Eist was supposed to have his card in the Skellige deck. This however did not happen.
