Time's Ever-Shifting Sands

In the present day of Nosgoth, Kain discovered that his murder of the once-beloved King William had been the catalyst for an uprising, a purge of the so-called vampire menace. Carving a path through many vampire hunters, Kain stumbled upon a horrific scene. A mob cheered as, front and center a guillotine blade shot downward and severed head from neck. The victim of this public execution turned out to be Kain's one-time benefactor Vorador. And his severed head was held aloft for the bloodthirsty crowd by none other than the Oracle of Nosgoth, the man who had sent Kain on this course in the first place, who had warned William of his coming, who had given William the Soul Reaver. And now, this man singled out Kain himself as the very last vampire in existence.

Fleeing the mob and killing any who got in his way, Kain pursued the Oracle. Cornering him, Kain learned the truth. The Oracle was in fact the corrupted and insane Time Guardian Moebius and Kain's trip through time was deliberately orchestrated, Moebius knowing full well that the two Reavers existing simultaneously in the past would create a time-shuffling paradox. This temporal shuffle would last for only a moment but a moment was all it took for Kain to change history by pre-emptively killing William.

This in turn allowed Moebius to make a martyr of the boy-king, casting blame on the vampires and sparking a genocidal purge of their kind. And all in service to his old Elder God who now, rather than simply shun the immortals for their exemption from his feeding cycle of death and rebirth, sought to reclaim those souls from their immortal vampiric vessels.

Intent on finishing what he started, Kain was made to do battle with champions pulled from various eras of the timestream before reaching the Time Guardian himself, cleaving Moebius' head from his neck in one decisive swing of his sword. Confiscating the hourglass that serves to channel Moebius' Guardian powers, Kain then answered Mortanius' call to return to the Pillars and restore the Pillar of Time.
