Diablo:

The dragon flies faster than the wind
Through the darkest sky.
The punishment will be given by the King
For a disgusting lie...
He was eager for the battle every night
When the evil's going down...
The somber castle and the puddles of the blood
Where that King was found.
Nobody heard his dying scream
Which was disturbing by the quiet...
She realized it wasn't a dream
Crying at his grave in moonlight.

Princess:

Oh, generous knight, you have chosen the way
With the threat of the fight
In the shadow of the bay.
Hear that voice and her mystery song will survive.
Oh, Knight, she's a ray in your life...

Diablo:

And now he's a ghost
Who wanders among the century-old walls.
The destiny did not belong to him...
There's no time to fall in despair.
But his soul loudly cries,
He knows the wind will never change.
Sinister spirit of sacrifice
Reminds about Knight's revenge
For the death and for the pain,
For the dusking fright.
When she sings the prays of his name
In gloomy day he'll see the magic light...
