Legacy of Kain is a series of dark fantasy action-adventure video games primarily developed by Crystal Dynamics and formerly published by Eidos Interactive, then Square Enix Europe after 2009. The first title, Blood Omen: Legacy of Kain, was created by Silicon Knights in association with Crystal Dynamics, but, after a legal battle, Crystal Dynamics retained the rights to the game's intellectual property, and continued its story with four sequels. To date, five games comprise the series, all initially developed for video game consoles and later ported to Microsoft Windows. Focusing on the eponymous character of Kain, a vampire antihero, each title features action, exploration and puzzle-solving, with some role-playing game elements. The series takes place in the fictional land of Nosgoth—a gothic fantasy setting—and revolves around Kain's quest to defy his fate and restore balance to the world. Legacy of Kain: Soul Reaver introduced another antihero protagonist, Raziel; the adventures of both characters culminate in Legacy of Kain: Defiance. Themes of destiny, free will, morality, redemption and the hero's journey recur in the storyline, which was inspired by ancient literature, horror fiction, Shakespeare's plays and gnosticism. The Legacy of Kain games have enjoyed critical success, particularly receiving praise for high-quality voice acting, narrative, and visuals, and, as a whole, had sold over 3.5 million copies by 2007. The Legacy of Kain series had been available for external developers to license through the Square Enix Collective service until 2022. That year, Square Enix sold the rights of the series to the Embracer Group, who have expressed interest in developing sequels, remakes and remasters of Legacy of Kain. Games Blood Omen: Legacy of Kain was created by Silicon Knights under the direction of Denis Dyack, with assistance from publisher Crystal Dynamics, and was released in 1996 on the PlayStation. In 1997, it was ported to Microsoft Windows. Dyack conceived the "vampire project" under the title The Pillars of Nosgoth in 1993, and Crystal Dynamics producer Lyle Hall chose this fantasy concept over two other proposals (one of which was Too Human). Pursued in hopes of bringing a strong narrative and artistic cinema to consoles, it was built as "a game which adults would want to play", featuring an unconventional hero and gameplay that demanded thought as well as reflexes. Developed as a 2D action-adventure game with role-playing game elements, it debuted to positive critical and commercial reception. Selling points included its 50+
