The franchise was unique at the time for its choice of an anti-hero as a protagonist. Much of the story revolves around the vampire Kain and his destiny as Nosgoth's savior. The series is set in the mythical realm of Nosgoth where the land's two dominant races, the Ancient Vampires and the Hylden, are locked in an ageless war for its control. Crystal Dynamics took over development after the release of the first game and went on to add four sequels.
The series broke new ground with its high quality of voice-acting and engaging storyline featuring complex and often dark characters. Originally created by Silicon Knights in association with Crystal Dynamics, Legacy of Kain is an action-adventure series known for its outstanding narrative and involving puzzle-based gameplay.
