Raziel proceeds to explore Nosgoth after his encounter with Kain at the Pillars –

Raziel V.O.
I didn’t know what impulse stayed my hand – why I had so willingly allowed Kain to escape me, when I had pursued him for so long.
I had no reason to trust Kain, after he had valued me so little.
And yet I found myself intrigued by his words.
I had been too cruelly used to so gullibly play his pawn – but if this world truly had secrets to divulge, I was determined to expose them.
 

Raziel V.O.
From the moment of my arrival, I had the constant and palpable sensation of being watched. Someone, it seemed, was keenly interested in my presence here.

Raziel discovers a large stone door, painted with a familiar effigy–
 

Raziel V.O.
From the look of it, this door had been sealed for centuries.
I began to realize it was no mere coincidence that I found myself standing here – beneath this winged figure, with blue skin and cloven hands so like my own... and bearing this unique key.

Raziel inserts the Reaver into the door's lock–

Raziel V.O.
And so it was with a sense of gravity and trepidation that I unsealed that ancient door, and crossed the threshold.

The Elder God

As Raziel cautiously descends an ancient, subterranean passageway, a voice calls his name, barely audible at first, then gradually growing louder as Raziel descends deeper.  As he reaches the final bend of the passageway, he finds himself at the threshold of a magnificent underground chamber.  The Pillars descend into this chamber, intersecting a platform engraved with arcane symbols.  Water surrounds the dais, and dappled reflections are cast on the surrounding walls.
Raziel steps onto the central platform, and marvels at the scenes depicted in murals along the walls.  He recognizes his own ragged form in these heroic figures – the blue skin, the wings, the cloven hands.  He holds up his hand, mentally comparing his anatomy to theirs; he looks at the Reaver imagery... he’s trying to put the pieces together.

Raziel V.O.
As I entered the chamber, I sensed that it had been sealed for hundreds – perhaps thousands – of years.
And while this room was clearly built when the Pillars were erected, I knew that no human hand could have shaped this place – and that perhaps it had never been seen by human eyes.
The surrounding murals depicted a winged race, their features so like my own but beautiful, where mine were grotesque... and angelic, while mine were demonic.
I tried to decipher these images...
...a great war, but with combatants like none I had ever seen...
...the Pillars, raised by this winged race, who thus defeated their adversaries...
...the winged beings again, writhing in agony, apparently afflicted with the same blood-thirst I had so recently suffered...
And throughout the chamber, inscribed everywhere, images of the Reaver itself.
Was this what Kain had urged me to discover?
I wondered...

The voice of the Elder God, now sharply clear and distinct, bubbles up from the depths of the chamber, as if in answer to Raziel’s unspoken question –

Elder God
Lies, Raziel...

Raziel recognizes the voice, and realizes that it's rising from the watery depths beneath the platform.  As he steps to the edge and looks down, he sees that the Pillars descend into the murky depths of the chamber – and coiled around them are the tentacles and amorphous mass of the Elder God.

Elder God
(warning)
Do not be deceived.

Raziel
(sarcastic)
Ah, my ancient ‘benefactor’...
And I dared to hope we had parted ways forever.  Your silence was refreshing, while it lasted.
No doubt you have a conveniently inexpressible reason for your presence here?

Elder God
Do not be insolent, Raziel.
I am eternally present – here and everywhere; now and always.
I am the still center of the turning wheel, the hub of this world’s destiny.

Raziel
(distrustful; taunting)
But perhaps not so omnipotent as you’d have me believe.
Your hold on me appears to be tenuous.  I no longer seem to need you, yet I’m guessing you still need me.

Elder God
This impudence is unworthy of you, Raziel.
Do not forget that you have a task to fulfill here.
You are indebted to me.

Raziel
(incredulous; disgusted)
Indebted?  You would have me show gratitude for a ‘gift’ I didn’t ask to be bestowed?
Do you forget that you forced me to inhabit this vile carcass –

Elder God
(interrupting)
– I restored you to yourself, Raziel.
It was Kain who destroyed you.
The very enemy you have just let slip through your grasp.
(threatening)
Do not fail me, my servant...

Raziel
I serve no one – not you, not Kain... and not your lackey, Moebius.

Elder God
(ominously)
Moebius is my good servant.
I have many.

Raziel
(sarcastic)
And if I tell Moebius that he’s worshipping a giant squid, do you think his faith will falter?

Elder God
(a little peeved; he’s sensitive about the squid thing)
You have grown willful, Raziel.
But beware – to embrace a serpent is to invite poison into your heart.
Kain is a sinuous beast; he will seduce and deceive you.
You pride yourself on your free will, yet you let that degenerate deter your resolve.

Raziel
I harbor no illusions about his integrity, nor anyone else’s.
In fact, I am beset by manipulation on all sides.  I merely seek the truth.

Elder God
These are the fathomless truths, Raziel:
The agony of birth and death and rebirth – this is the Wheel of Fate, the purifying cycle which sustains all life.
Vampires are an abomination, a plague which leeches this land of its spiritual strength.
They obstruct the flow of life and death – their souls stagnate in their wretched corpses.
But the Wheel must turn; Death is inexorable and cannot be denied.
Your destiny is irresistible, Raziel – you are my soul reaver, the scourge of the vampires, reaper of their apostate souls.
Remain steadfast.  End the vampires’ parasitic curse, and restore Nosgoth.
Kain’s blood belongs on your hands.

Raziel
Kain indeed deserves to die, for condemning me to this repugnant form.
But if and when I kill him, it will be for me, alone, to decide.

Elder God
Kain destroyed you without a flicker of remorse.
He tore the soul from your noble corpse, and after you had served him faithfully for a thousand years, he discarded you in the Abyss on a jealous whim.
(pause)
Remember your rage, Raziel – let it guide your hand.
