The game's first cinematic sequence shows why Kain casts you(Raziel) into the Vortex of the Dead. The reason he does so is because you grew your wings before him. As he circles you, you are suddenly drenched in pain as Kain rips your wings. As you lay there wounded he orders your vampire brethern to toss you into the abyss. After an eternity of pain and suffering you finally hit the bottom of the abyss. A voice suddenly summons you. He tells you he can help you get vengance on Kain. You tell him you don't deserve this fate and he replies by telling you that you have no choice. You find the cape that marked you as clan leader and cover up your face to hide the fact that your jaw has disintergrated off your face. You reluctantly agree to his offer to help. You soon discover that instead of blood you hunger fo souls.
