I do not own Cannibal Corpse's A Skeletal Domain, and this awesome song belongs to the amazingly badass artists mentioned above. I also do not own the Legend of Korra. Credits go to the owners and creators of this great show. Please review and comment if you want.

Prologue

On a planet called Mmor-Teter, World of Benders' weeks before the Second Invasion.

Narrator's p.o.v.

Coronythillas silently watched many of his subjects from the main forces of the Legion of Death as they finished assembling before him, him standing on a balcony that belonged to one of the Leg-Defensetowers of his Arachnatadel of Decay. For the past three days, after the short and straight-to-the-point broadcast of the second Lord-Patriarch's war-summoning, his warriors and the Conquered ( Multitude or allied forces who had been brutally overwhelmed and either was forced to surrender or did it of their own free will [ corrupted individuals/traitors ] ) zealously and eagerly poured down onto one of the Legion of Death's most essential and heavily guarded planetary bases' barren and diseased surface like a sick, nightmarish, deathless and endless swarm of skeleton monsters, pestilent-fleshed abominations, ghastly apparitions and disgustingly carrion-like mutants, to heed his perversely godly wishes and fatally mortal commands.

The blasphemous and chilling and maddeningly skin-crawling noises from those monstrosities; from the sounds of devious murmuring and gurgling, to hurling and retching, to the cracking of bones, sloshing of liquefied organs and body parts and squelching of movements through swamp-like and decaying terrains, to the ultimate screaming and shouting of pain, bliss and death as countless of formerly human or soon-to-be-no-longer-human or lesser xeno souls' body began to mutate, either melting away to form great masses of repellently amorphous and hostilely sentient tissues, or exploding from the inside out to reveal new, unnatural and utterly alien portions of the now oblivious carcasses, controlled and ruled over by a brand-new, horrifying and monstrous consciousness, obviously having undergone constrained and terrifyingly slow mutation and transformation; were like music to their leader of necrometamorphic existence.

Once there was only silence and fervently morbid dedication in the air, the Decayed Commander spoke, his voice hoarse and raspy, as if it was the vocal archetype of a pitiless, talking corpse, but also had a malevolently insidious quality to it, just as though this horridly tall and eternally rotting husk was under some eeriely mysterious influence from a far greater power of unknown origin:

"In ancient times, War was known to possess the ultimate power of carnage, destruction and annihilation; in short, War was a force, an unstoppable force, to be reckoned with. However, there is a more significant truth behind it: War is destructive, but only to the weak-willed, for the strong can use War to achieve their goals, such as the Protoss and the Eldar ( from Warhammer 40k universe ), and humans. Yea, They Who Hast Mortality To Die Beautifully. Weak in the flesh yet strong in the will".

Upon hearing their Lord-Patriarch mention the word "humans", the ghoulishly undead, rotted and putrescent horrors grunted and snarled and jeered and snapped with contempt. Even the ones in the early stages of mutation couldn't help but bellow profanely wicked languages and tongues beyond mortal comprehension, which originated from none other than within Zulathulhu's Realm of The Unknown itself.

"Why? Because they have courted War before. They are just the same as any other species and subspecies in all of the realities. They have the will to fight. My old friend, Agrigula, he just didn't understand this; and as a result, perishment was the cause of his own demise. No, the ultimate power of carnage, destruction and annihilation has no longer belonged to War, but Death! Mortality! Fatality... For Death arrives just as fast as War, like a hurricane beside the former's cataclysm. For Death, too, arrives as unexpectedly as War, like the Grim Reaper alongside Conquest. And for Death can be as slow as decay, and as malicious as the Firstborn's ( from Clive Barker's Jericho universe ) hate withal! The moment Death seizes your sight and grips your heart, you know there is NO escape".

Now the fiends down below growled and hissed and screeched in agreement, becoming more and more feverish and excited as seconds passed. And suddenly, their environs seemed to beat and pulsate, throb and respire, and shudder and rumble like a huge, world-class, wakened beast-matriarch, longing for new offsprings and hellbent on ruling a vaster territory. Clearly inspired by the second part of Coronythillas' speech in this moment, without warning, there was a terrible and outworldly roar from the planet's core, followed by a series of awesomely dreadful, seismic shaking and quaking, which lasted for about seven minutes. After that, the bone-like, decaying-tissued and obviously living Arachnatadel opened its mouth, that was the upper part of this very abomination of a building, and belched forth a massive Astral-Empyrean Maggot, as big as a Zerg Leviathan, it launching itself straight up to the sickly brownish, yellow-green sky, joining its eight other siblings/friends, floating around in their maniacally sublime birth-joy.

After witnessing the genesis of another one of the Legion of Death's space-faring Battlebeasts with total satisfaction, the Pestilent Lord-Patriarch continued:"And so, my deathly agents, with the All-Lord's trust placed upon us, we will overrun, and overwhelm, the World of Benders in His name! We shall spread disease and decay far and wide until all is bleak! We shall march and destroy every city and every bastion, then infect and devour every single human and crush their every attempt of resistance, and then sacrifice that realm as our gift of pestilence to our true Father! We shall make Chzo cower and tremble with our festering might and decomposing splendor! We shall make even Nurgle shrink and recoil with our fetidly and cariously glorious putrefaction!

And, my rancidly loyal subjects, we shall surpass everything Phoborth and the Legion of The Damned have ever accomplished! We. Shall. Extend - our influence from that is known to us dearly as... the Skeletal Domain...!".

As soon as Coronythillas finished his speech, all of a sudden, Cannibal Corpse's A Skeletal Domain was blasted straight from somewhere within the Arachnatadel - so grim, so demented, and so gruesome, it marking the beginning of Zulathulhu's forces' Second Invasion.

Trapped beneath rotting remains!

A slow decay of life takes its form!

Withered death and bone emerge

from cemeteries of the earth,

replacing all that is known from this world!

Towering structures take shape

as more cities are laid to waste!

Survivors of this morbid fate,

the reborn, meek not, live not, dead,

are left to start anew!

Misshapen and half-mutated!

Not a zombie, not a human!

Evil creatures grew!

Not one thing left alive but them!

The strongest will begin to reign!

A new society takes place

where the way of the cannibals

rules in this skeletal domain...!

A kingdom of the - DAMNED...!

Carnal war consuming them by

eating flesh for nourishment!

Solution for a short-term survival!

Slaughtered are the weakest first,

feeding those with evil thirst

as blood of the dead saturates the ground!

Again, the end has begun!

Another kingdom will be DAMNED...!

Survivors of this morbid fate,

the reborn, meek not, live not, dead,

are left to start anew!

Misshapen and half-mutated!

Not a zombie, not a human!

Evil creatures grew!

Not one thing left alive but them!

The strongest will begin to reign!

A new society takes place

where the way of the cannibals

rules in this skeletal domain! ( domain! )

Survivors of this morbid fate,

the reborn, meek not, live not, dead,

are left to start anew!

Misshapen and half-mutated!

Not a zombie, not a human!

Evil creatures grew!

Not one thing left alive but them!

The strongest will begin to reign!

A new society takes place

where the way of the cannibals

rules in this skeletal DOMAIN!
