The game begins by retelling the final battle with Kain in the original Soul Reaver: Raziel confronts Kain in the Chronoplast time machine, and the two enter a portal through time to emerge thirty years before the events of Blood Omen. Moebius the Timestreamer tells Raziel that Kain is at the Pillars of Nosgoth, and Raziel goes and confronts him. Kain reveals he has plans to transform history to avert the consequences of his decision, when his past self refused to sacrifice himself to restore Nosgoth and doomed the land to eternal decay. Kain vanishes, and Raziel continues northward and finds the vampire Vorador, who hints at a profound secret that the deceased vampire Janos Audron once knew. Deciding to speak with Janos, Raziel returns to the Sarafan stronghold where he again meets Kain, who tells Raziel the Soul Reaver is the only way history can be changed, as he did so when battling William the Just with a future incarnation of the Reaver in Blood Omen. Kain hands Raziel the material Soul Reaver, and the spectral Soul Reaver Raziel has coils around it. Raziel is faced with a dilemma: kill Kain and submit to fate, or establish his free will by refusing. Raziel avoids dealing the death blow, changing time again before Kain vanishes. Raziel finds Moebius in his timestreaming chamber and forces him to send him to the past before the vampire purge of the Sarafan Order, but Moebius tricks him.
