Necropolis: Realm of the Dead

Cold and silent is the land of the dead
Eternally blazing storms make no sound
As lightning strikes the bone-white ground
In the bravest Necropolis inspires dread
Gleaming mountains black as obsidian
Touch the dark sky in the distance
Temples of forgotten existence
Guarded by cursed iron Praetorians
Sovereign is the Necrobane
Titan Prince and master here
Where he goes, the end is near
Mortals feel no more pain
He dwells in the greatest mausoleum
Where he wrote the book of death, Liber Necropolis
A book to make eldritch ones scream and hiss
To make the unholy things wail and flee him
Z, the last and third of the Trinity
First Order, then Extropy and the End
Appointed, the universe they tend
Titans of power few dare to see
Watchers stand guard over the graves
Guardian statues of living stone
Set to protect old bone
Gazing out over dark Byzantium waves
Under musty crypts dwell the nameless
Creatures forgotten long ago
Insanity and fear they sow
To gaze upon them shall bring madness
Still and peaceful are the Resting
Citizens in the ream of undeath
Animated bones with a chilling breath
Sleep in crypts with ornate cresting
Beastly remains litter the Valley of Tears
Fallen demons from a war so great
When Crawling Chaos tried to breach the gates
The war that lasted so many years
Afterwards came Vagash the Lich Queen 
While the Overlord was visiting the dead
Sol, Prince of Fire and Order ruled in his stead
She fell to the fire and lost her powers obscene
Cold and silent is the land of the dead
Necropolis still stands through plight and war
Eldritch incursion happens no more
And evil curses remain unsaid
