a suit against Crystal Dynamics for rights to the Legacy of Kain IP, requesting an injunction to prevent Crystal Dynamics from marketing the sequel. The two studios settled their legal dispute privately, and Crystal Dynamics and Eidos retained rights to the Legacy of Kain franchise, provided that Soul Reaver acknowledge Silicon Knights as the series' original creator. Paradise Lost was the original inspiration behind the concept, and sources such as Rabbinic lore, vampire mythology, Eastern myth and mysticism were also key influences. Visual cues were borrowed from films such as The City of Lost Children and The Cabinet of Dr. Caligari, and H. P. Lovecraft's Cthulhu Mythos.

Its crew was wary of relying too strongly on the original Blood Omen as an influence, and expanded on the franchise's backstory in hopes of starting a new series.

Defiance represented "a whole new approach" to the franchise, with more focus on drama, an overhauled combat system, and scripted, cinematic camera angles. After fan speculation that it would become the last Legacy of Kain title, Crystal Dynamics unofficially confirmed on their forums that another game was being worked on, though no announcement followed, and, in 2005, their next project was
