Extract from the Liber Diabolus Domus, written by the Pravaii Hierophant. As such some of his comments may have a distinct bias towards Pravaii supposed superiority.;

"The Nine Hells, also known as the Pit, the Terror and Killar's Realm, are a set of inter-dimensional realms of existence outside of our own. What is unknown is whether they existed before the Gods came to Tal'Vorn or if Killar and the Dark God created them for their own uses. This single point of contention has caused hundreds of years of debate within the Life Sect, the Dark Sect and those who worship Killar. The Elves, being one of the few truly immortal Races and thus with more right to make their beliefs known, believe that the Nine Hells are indeed the creation of Killar and the Dark God, known also as the Corruptor.

When Killar came to Tal'Vorn, he found that the true world was not a suitable place for his offspring to live, the land being far to clean and bright, missing the essential darkness and blood that Killar longed for. Instead the Bloody Handed Slayer sought out a way to create a world where his own creatures could live. He failed. Killar is not a good known for his knowledge of magic, his skill at creation or his attention to detail, preferring instead to simply slaughter anything and everything that stood against him. Indeed it could well have ended there, Killar leaving Tal'Vorn as a world hopeless for his Demons, but something else happened.

The Corruptor approached Killar, as was his wont, and used guile to persuade the Lord of Slaughter to allow them to aid each other. When Killar agreed, the Dark God tore open a hole in space-time, revealing the Nine Hells to the Blood Gods raging eyes. Seeing in that torment ridden place a world that He could control and make His own, Killar is said to have laughed aloud with the sheer vicious joy of it and stepped forth into that hellish dimension. What the Dark God failed to tell Killar was that once within, the Lord of Slaughter would not be able to escape again.

Killar did not realize this for many centuries, so focused was He upon populating the Nine Hells with his demonic legions. He, however, could not access the Sixth Tier of Hell, called the 'Tier of Despair' in some of the older texts available. This was because the Dark God has taken that place to be His own realm, preventing Killar's access. Perhaps inevitably, Killar grew tired with his realm, desiring to walk the mortal lands once more, to drench his hand in the blood of the living once again.

It is said that more Demons were born in the moments after Killar discovered that He was trapped then at any other time in Tal'Vorn existence. He raged uncontrollably and constantly and indeed still rages against His imprisonment, more and more Demons born from his anger with each passing moment. This, it seemed, was the Dark Gods plan, to trap Killar and his legions in a place where they could no longer effect the Dark Gods scheming.

However the plan was not as successful as the Dark God hoped. Humans arrived on Tal'Vorn and VCealic began to gather the allegiance of the Races. The DragonKing sought out the Demons for many months, knowing that their power would be unfathomably useful in the coming war. Yet he was unable to fined any trace of the Bloody Handed Slayer or His creations. So, in desperation, Vralic turned to his God for aid. Shaltar, knowing that Vralics desires and aims where just, tore open the bounds of the Nine Hells far enough for the DragonKing to speak with the God of Slaughter.

It is said that negotiations between God and Dragon took weeks, Killar only able to speak when his rage subsided, a rare occurrence. Finally they reached and accord. Though Killar himself was physically still trapped, He was granted the ability to project a part of himself into reality, allowing him to directly speak with morals once more. Vralic, and thus the DragonGod Shaltar, then permitted a certain number of Demons through into reality on the condition that they would assist during the Great War.

Though this sort of agreement may seem an anthesis to Kiallr, be understood that the Bloody Handed Slayer is not actually an 'evil' God but more of a God without the normal set of morals to guide Him. Thus he could see the reason and the benefits behind such a plan clearly enough when he was not angered. With the bonds of his prison thus weakened, Killar's Demons could slay in his name once more, the life blood of the dying feeding Killar and increasing his power.

The Great War was, in Killar's eyes at least, absolutely glorious. Blood shed on a scale never before seen, murder, slaughter and destruction, all of it feeding the Lord of Slaughter, allowing him to force more Demons through into reality. This is an exponential course. As more Demons enter Tal'Vorn the more Demons there are to kill in Kiallr's name and thus the more Demons that can be unleashed. It is said that Kiallr will only ever be free when the Nine Hells are empty.

Yet this would take millennia and Killar is not a patient God. Shortly after regaining His partial freedom, Killar came across something that caught His eye, almost confusing the God. He had discovered the Pravaii, the sorry remnants of the Elven separatists.

Being a God, Killar could see what lay within their hearts, their burning desire for vengeance and immortality, the only things that had kept the Race breeding and eking out a meager existence in the harsh Grey Land. The idea was a simple one. Corrupt the Pravaii further and then grant them immortality once more, but with a heavy price. If the Pravaii were desperate enough then they would accept. And once they had accepted and had a taste of immortality once more, then Killar could demand more and more for less and less.

Killar appeared before the Pravaii Hierophant as a blood covered skull, dripping with gore and strips of ragged flesh. Though the Hierophant was in no way impressed by Killar's appearance, the Pravaii did agree to Kiallr's proposal. One year of immortality for a single Pravaii for every soul sacrificed in His name. From that moment Killar's power has increased exponentially, more and more Demons pouring though into reality from the Nine Hells. Killar himself drives his creations on into ever more twisted expressions of blood lust and killing, howling out the Slaughter God's name as the drink the blood of the living.

The Demons themselves are as varied a group of individuals as any of the other Races of Tal'Vorn. Each is unique in the same way that each human is unique, but they can also be loosely grouped into the emotions that they represent. Broadly speaking, the majority of the Demons that walk Tal'Vorn will be Slaughter, Rage or Anger Demons. However there are many more types of Demon that exist within the Nine Hells, each showing within itself he very living embodiment of some sort of negative emotion.

Slaughter, Rage, Hate, Anger and Fury Demons focus upon killing for killings sake and are the most common image summoned up when people think of Demons. They are hulking, powerful beings that lust for combat and the feel of blood upon their skin. Typically bestial or monstrous in their appearance, these types of Demons are abhorrent to behold but only in the way that a wild animal is.

Lust Demons are perhaps the most normal of all the Demons, at least in external appetence. They seduce their victims before killing them and are thus pleasing to the eye and to the mind. Yet they have another form, equally beautiful as their illusion and yet also deeply disturbing. Each of these 'true' forms is unique to the individual Demons, but each is both terrifying and strangely fascinating.

The most horrific to the eye however are probably the Fear and Terror Demons, monsters whose sole purpose is to instill absolute soul-chilling, heart-stopping terror into their victim. They do so in a number of ways, some of the Demons simply causing an aura of such horror that it drives men mad who approach the Demons, some seek to terrify unsuspecting civilians in the dark of where they are not expected, some take great care and pleasure from working with Dementia Demons to drive a person insane with fear, uncertainty, doubt and paranoia. However the Demons choose to do their work however, the outcome is always the same. Death.

Cruelty Demons are just that, unthinkably cruel. Whilst all of the other Demons will kill you relatively quickly, Cruelty Demons take to thoroughly tormenting their victims to death, either through pain, fear, sorrow, anger or blood loss it matters not to the Cruelty Demon. They are bizarre creatures, festooned with torture devices and barbed knives, designed to cut and harm with horrific ease and terrifying precision.

Greed and Hunger Demons work opposed, dividing their victims between each other in an effort to outdo the other, one with starvation and the other with gluttony and avarice. They embody the spirit of what drives creatures to these extremes of physical existence and thus physically are perfect representations of what they are. Greed Demons are covered in jewelry and expensive clothing hides their immense bulk, whilst the Hunger Demons are emaciated and skeletal, dressed in rags and strips of dirty cloth.

Insanity and Dementia Demons are some of the rarest of all of Killar's children, a confusing fact when you bear in mind that Killar himself is indeed irredeemably insane. The Demons themselves are mad, gibbering creatures that take a twisted delight in inflicting their own madness upon the minds of other living things upon Tal'Vorn. As for their appearance, none can say, for anyone who has been close to an Insanity Demon is no fit condition to talk about it afterwards and those who are approached by a Dementia Demon have to invariably be killed to stop their blood-fuelled, insane rampages. These sorts of Demons are perhaps the highest threat to any ordered society for hunting them down is almost impossible without highly specialized and exceedingly rare weaponry and equipment.

Night Daemons are the rulers of the Demons. Indeed it is said that they are a different breed to the other Demons, a different sort of creature all together that simply works with and controls Killar's minions without actually being one of them in the strictest sense of the word. It is true that they represent no specific emotion or expression of existence and that they do appear to have total free will over their own bodies, their actions and their choices. They are perfect in appearance ,though several things mark them out as what they are. Their skin is always a pitch black and their eyes milky white. Some of them have cloven hooves instead of feet, or bat like wings or horns emerging from their temples. They are both strong and powerful with magic, expressing the true aspects of Blood Magic in their spells and incantations. Truly they are the rulers of the Demon Race and fully deserve their extended name of Daemon.

The Nine Hells are a twisted set of dimensions, each interlinked and yet very separate, each of them unique and possessing of it's own landscape and craft. The First of the Hells, named the Hell of Truth, is identical to reality with one notable exception. If it could possibly have gone wrong in reality then in the First Hell it did. If a toss of a coin is the difference between life and death then in the First Hell you will die.

The Second through Fifth Hells are the Elemental Hells, worlds that each fully represent the true aspects of a single element in it's full power. Indeed three of these Hells are home to three of the Gods. The Second Hell, the Hell of Fire, is a burning world, the very ground aflame and the sky ablaze. It is beyond hot, the very mind unable to comprehend the horror of an entire world aflame, where flesh runs like water with the heat and even metal simply evaporates with the heat.

The Third Hell is the Hell of Water. A frozen sphere filled within endless water it is actually home to many millions of types of fish and deep sea creature, each feeding upon each other, the water lit by the power of it's greatest resident. There, in the centre of this watery paradise, is the palace of the God of Water, Hydros himself. Here the Laughing God is free, without the plotting and machinations of the other Gods. In the Third Hell He can create the creatures He so adores, the living fish and other beings of the sea.

The Fourth Hell is simply a hunk of solid stone, the Hell of Earth, run through with endless seams of riches and precious metals, filled with jewels and weight of gold unimaginable. Though it is named a Hell it is also the Heaven of the Dwarves, where their creator, Terra the Earth God, takes their souls when the Dwarves die.

The final and fifth Elemental Hell is starkly different to the other three. It is simply there, an endless expanse of existence with no land, water or living being within it. It is the Hell of Air and the realm of Aeros the Sky Lord. He revels in it's emptiness, in the bottomless and roofless freedom of existence than such a place allows him to live in, the fearless joy that is his and his alone to explore.

The Sixth Hell is the Hell of Despair and is totally under the control of the Dark God, also known as the Corrupter. The Corrupter maintains an iron grip over his benighted realm, permitting no light to exist within the Hell, and demanding nothing more or less then absolute obedience from those He has trapped within the darkness.

The Seventh Hell is controlled by Killar, a flat wasteland called the Hell of DemonKind and is the one true home of all the Demons, the place where they are spawned and where they grow into the monsters that they will become. It is highly segregated, each type of Demons residing with others of it's own type and war between the types is very common, especially as most of the Demons will simply kill anything nearby by just because it is there. In the centre of the Hell is the location of the entrance into Tal'Vorn, a weeping sore in reality that opens periodically for a brief time. When the rift opens it sparks of a flurry of movement across the Hell and indeed from the Eighth Hell as the Demons and the Night Daemons fight each other for a chance to break through into reality and gift blood to their God.

The Eight Hell is the smallest and is called the Hell of Night. As the name suggests it is the home of the Night Daemons and was shaped to their will long ago into an immense castle upon a floating spire of stone. However it contains no link to Tal'Vorn and thus the Night Daemons must travel to the Seventh Hell, fight through the endless ranks of the Demons just for a chance to spill blood and cause chaos in the name of Killar. Of course the creatures have many advantages compared to the Demons, especially within the Eighth Hell. It is said that only one human has ever managed to step foot within the Hell of Night and that he is still there, cowering and gibbering in the depths of the castle, surviving off the scraps of flesh that the Night Daemons do not eat, unable to escape and to afraid for his soul to kill himself.

The final Hell, the Ninth Hell, is Killar's Prison. Nothing can exist within the Ninth Hell other then Killar Himself, the raging God filling the confines of His own Hell from end to end, constantly screaming to be free, to rend and tear the flesh of the living, His screams echoing always out into the other Hells, driving His creations into a frenzied euphoria of blood letting and slaying, all in a vain attempt to appease Killar, to somehow allow Him to regain some sort of sanity, some sort of grip upon reality.

Killar is the God of the Demons and he represents what they truly are. Blood thirsty, raging creatures that are, above everything else, one thing in importance. The Demons are totally, utterly, and without any chance of redemption or cure, insane.

Extract from Killar's ramblings. This goes on constantly and has been so for the last thousand years.
