At the dawn of a black existence

The dark one has opened the gates
My soul is swept away
I behold the dawn of a new life
I see heavenly light
But it shall turn into black
For the light in me is fading away
Towards the dawn of a black existence
I spread my darkened wings
As a sign of the arrival of me
It is like a dream
I have passed through the gates to eternity
To a land in obscurity
Passed through darkness and light
And the darkness remained
In this immortalised shape
I will be in this delightful darkness forever
And to eternally serve my master satan
