Khorne, also called the Blood God and the Lord of Skulls, is the Chaos God of Blood, War and Murder. His domain covers the most basic and brutal of sentient emotions and actions, such as hate, anger, rage, war and killing. Every act of killing or murder in the material universe gives Khorne power; the more senseless and destructive, the better. However, though Khorne is the God of bloody slaughter, he is also the God of martial pride and honour, of those who set themselves against the most dangerous foes and earn victory against the odds. A devotee of Khorne is as likely to be an honourable champion in combat as a blood-crazed slaughterer. Khornates take no artful approach to killing, seeking only to slay rather than to inflict pain, because while the blood of their victims strengthens Khorne, their suffering actually empowers his nemesis Slaanesh. The name "Khorne" derives from his name in Chaos' daemonic Dark Tongue, Kharneth, meaning "Lord of Rage" or "Lord of Blood". He is the mightiest and the second oldest of the four major Chaos Gods, fully coming into existence in the Immaterium sometime during Terra's European Middle Ages in the 2nd Millennium.
Khorne is the Blood God, Lord of Rage, Taker of Skulls. He is wrath incarnate, the embodiment of a never-ending lust to dominate and destroy. It is his sole desire to drown the galaxy in a tide of slaughter, to conquer and kill every living thing until there is nothing left but spilt blood and shattered bone. The Blood God is commonly depicted as a broad and muscular humanoid who stands hundreds of feet tall. He has the face of a savage, snarling dog, though his twisted features are all but hidden by a baroque helm decorated with the skulls of conqueror kings. Khorne's exaggerated physique is further distorted by heavy, overlapping plates of armour fashioned from brass and blackened iron. His every word is a growl of endless fury, and his roars of bloodlust echo across his realm.
Khorne broods from a throne of carved brass, atop a mountain of skulls, The macabre trophies are the fleshless heads of his champions, stacked alongside those of their defeated opponents. A hundred thousand species are represented, from human heads beyond counting to Tyranid skulls the size of hive city hab-blocks. The ever-growing pile of bloodstained bone reflects the material victories of his followers, feeding Khorne's glory but never quenching his thirst for blood and death.
At Khorne's side rests a great two-handed sword, a legendary blade capable of laying waste to the substance of worlds with a single blow. This fell weapon is known by various names to the different intelligent races of the galaxy, including Woebringer, Warmaker, and the End of All Things. It is said that when Khorne takes up his sword, a single sweep can cut through reality itself, allowing Khorne's daemonic legions to spill forth into the Materium.
The code of Khorne is simple: blood and more blood. His only temple is the battlefield, his sole sacrament the spilled blood of nations. Consciously or not, all warrior cultures pay him homage with their acts of murder and destruction, from the headhunting tribes of backwater Feral Worlds to the planet-conquering warbands of the Chaos Space Marines of the World Eaters Traitor Legion.
Every single life taken in anger increases the Blood God's power. He looks well upon those warriors who slay their friends and allies, for they prove their understanding of a greater truth -- Khorne cares not from whence the blood flows, only that it flows. Friends or enemies, all the dead are equal in the eyes of the Lord of Battle. Those Khornate devotees who let a day pass without committing an act of bloody-handed slaughter inevitably incur the Blood God's displeasure.
Khorne is said to have inherited a martial nobility and honour, and considers the weak and helpless to be unworthy of his wrath. The battle-cry of the followers of Khorne reflects his desire for wanton violence: "Blood for the Blood God! Skulls for the Throne of Khorne!" Alternatively, they may cry, "Skulls for the Skull Throne!" In the throes of violence, Khorne's followers are also known to bellow, "KILL! MAIM! BURN!" repeatedly while hacking apart their enemies. Also, the Khornate Berserkers known as Khorne's Chosen often shout "Break their backs!" while in the thick of the brutal, bloody battle they so passionately seek out. Followers of the Chaos God Slaanesh, who Khornates see as degenerate scum who kill only for pleasure rather than to test one's self against mighty enemies, are favoured foes to face in battle, as are the servants of Tzeentch, who are seen as Sorcerers unwilling to engage in fair and honourable combat. Khorne's sacred number is eight, reflected in the organization of his armies, and in smaller matters such as the number of syllables in a Khornate daemon's name. Where possible, his warriors will form up into squads of this number. His primary colours are blood red, black and brass. Also note that the Mark of Khorne looks vaguely like a figure of eight or a stylized human skull.
