Legacy of Kain: The Dark Prophecy was intended to be the sixth installment in the acclaimed Legacy of Kain series, developed by Ritual Entertainment. Although production commenced in 2004, the project was ultimately halted after only a few months. This sequel to Legacy of Kain: Defiance was set to continue the narrative involving Kain, the Hylden, and the Demon Realm, promising to expand upon the story's rich lore. The game was initially aimed at multiple platforms, including PlayStation 2, Xbox, and Windows.

Despite its cancellation, the game's development has been partially documented by community members, showcasing concept art and screenshots that illustrate what could have been. Insights from former developers and fans highlight the potential of Legacy of Kain: The Dark Prophecy to deepen the series' narrative and introduce new gameplay elements, making its cancellation a notable loss for fans of the franchise.
