Simon Templeman and Michael Bell voice protagonists Kain and Raziel respectively. Supporting cast members include Paul Lukather as Vorador, Anna Gunn as Ariel, Richard Doyle as Moebius, and René Auberjonois as Janos Audron. Tony Jay played Mortanius in "Blood Omen", and returned as The Elder God in subsequent games; in "Defiance", Mortanius was recast as Alastair Duncan. Gordon Hunt and Kris Zimmerman provided voice direction from "Soul Reaver" and onward. The developers coordinated the actors by ensuring they were involved as collaborators, recording their dialogue together rather than in isolation, and thus established techniques which would later carry over to Naughty Dog's "Uncharted" series.
