Sun of the Endless Night is about Lucifer writing a letter to God. In this letter he states he’s tired of being the devil, the bad guy, living in the pit of hell, and wanting to finally go home.

Lyrics

Awoke from along dark sleep
Invoked by incantation.
Now I'm wide awake
Enjoying life's sensations.

You shouldn't have called my name.
You shouldn't have said it twice.
You shouldn't have called my name. 
I am the son of the endless night. Yeah!
The son of the endless night. Woah woah.
The son of the endless night. 
It's my name.

I've been down in this pit too long.
It's time for me to leave.
I hope you've heard these words.
I hope you hear my pleas.

You shouldn't have called my name.
You shouldn't have said it twice.
You shouldn't have called my name. 
I am the son of the endless night. Yeah!
Son of the endless night. Woah woah.
Son of the endless night
That's my name.

Help pick me up 
Before it gets too late.
Help fix me up
Before the beast inside awakes.
Help pick me up 
Before it gets too late.
Help fix me up
Before the beast inside awakes.
Before the beast inside awakes.
Before the beast inside awakes.
Before the beast inside awakes.

See the blind man on the corner
Holding out his hands.
His God has let him down
And he doesn't understand.

You shouldn't have called my name.
You shouldn't have said it twice.
You shouldn't have called my name. 
I am the son of the endless night. Yeah!
The son of the endless night. Woah woah.
The son of the endless night 
And that's my name.

Help fix me up, 
Before it gets too late.
Help pick me up 
Before the beast inside awakes.
Help fix me up
Before it gets too late.
Help pick me up
Before the beast inside awakes.
Before the beast inside awakes.
Before the beast inside awakes.
Before the beast inside awakes.
Before the beast inside awakes.
