"To hit the August '99 release date, we had to cut the last few levels of the game, and end on a cliffhanger that set up Soul Reaver 2. Originally, Raziel was going to hunt down and destroy all of his former brothers as well as Kain – and then, using his newly-acquired abilities, he would've activated the long-dormant pipes of the Silenced Cathedral to wipe out the remaining vampires of Nosgoth with a sonic blast. Only then would he realize that he'd been the Elder God's pawn all along, that the purging of the vampires had devastating consequences, and that the only way to set things right would be to use Moebius’ time-streaming device to go back in time and alter history (in the sequel)."
