Beyond the mountains of madness 
Crossing the river Acheron 
Lies the crimson battlefield 
Where Father and son will cross their blades 

On a flaming bat-shaped chariot 
The Infernal Emperor appears 
Matching his daring offspring 
Waiting for Cerberus to howl 

The guardian hound now screams 
And swords are raised with hatred 
Both forged in pain and blackness 
Destined to spread the veil of Death 

The battle doesn't seem to end 
Such is their ferocious rage 
Like hungry beasts upon their prey 
No more blood ties can hide their hate 

Suddenly the black-steel blade 
Held by the pretender's hand 
Pierces the Undead's wicked head 
As dragon wings shading the sun 

A wave of living darkness 
Effuses from the Emperor's heart 
Embraces the usurper 
Absorbing his soul and blood 

A triumphant voice 
Now echoes in the skies 

Now my son we're bound 
Reborn into the Black 
Masters of the Cosmos 
Now my son we're one
