"My armies are slain. My castle lies in ruins. My enemies have taken everything from me, all my wealth and power. But they could not kill me. I still walk the Earth, weak but alive. They have taken everything but the beating of my undead heart. Now they will learn of fear, these mewing babies who thought they could destroy me. I shall regain my powers, and come to them in the night. And my visits shall not be kind."
Blood Omen 2 takes place four hundred years after the original Legacy of Kain: Blood Omenm, in which the vampire Kain chose to rule the world of Nosgoth in its damnation rather than to die for its salvation.
Since the events of that period in time, Kain had become the powerful commander of an army fixated on ruling the Land of Nosgoth. In response to his ascension of power, another faction known as the Sarafan appeared in the land. The Sarafan are a group of militant and zealot humans led by a mysterious and potent figure, known only as the Sarafan Lord. Determined to wipe out the vampire scourge, the Sarafan clashed with Kain's army over decades of blood stained and infernal conflict. This war ended when the Sarafan triumphantly defeated Kain's army. In the final battle, the Sarafan Lord defeated Kain in Mortal Combat, stripped him of his macabre blade the Soul Reaver, and tossed him off a cliff into an abyss of apparent demise.
Yet, this was not to be so. Pure and true wickedness of Kain's ilk cannot be expunged so easily.
After more than 200 years drifting in a void of unconsciousness, Kain awakes groggily in a strange place with almost no memory of his formal self. Another vampire named Umah, had taken him in and revived him to health after Kain's little recollected and deadly battle with the Sarafan Lord. He is weak, and has lost most of his former formidable powers. Worse still, his trusted weapon the Soul Reaver is still missing. As Kain regains presence in the walking world, Umah begins to fill him on the events of recent past, while fragments of Kain's shattered memory return.
Umah recounts to Kain that when his torn body was found, it was revived and brought to the capital of Nosgoth, the city of Meridian. In the two centuries that Kain has been dormant in hibernation, the Sarafan have risen and taken fascist control over most of Nosgoth. Far from the great empire that they once embodied, the Vampires now existed only as a small resistance to the Sarafan, called the Cabal, in Meridian. It is into this resistance that Kain emerges and is now, by brotherhood and lust for vengeance, a part of. The ambition of the resistance is simple: Slay the Sarafan Lord, and the Sarafan Order will crumble.
Because the Sarafan have now knowledge of Kain's existence, he is the perfect agent to locate and kill the Sarafan Lord. Kain agrees to help the Cabal for the time being, until which time he sees fit to follow his own agenda, and seek revenge at all cost…
