The Ossiarch Bonereapers are a military force like no other – organised and efficient, led by generals created by the Nagash, Supreme Lord of the Undead, and lent a measure of his necromantic power. These terrifying bone constructs march forth in macabre splendour to claim the bones of the Mortal Realms so their numbers may continue to swell.
The Chaos Space Marines have been fighting a war of vengeance for ten thousand years, sallying forth from the Eye of Terror to wreak havoc on the Imperium that spurned them. This nightmare realm of warp-tainted space corrupts them in body and mind, but also grants them power. Combined with thousands of years of combat experience, they are some of the most deadly veterans of any fighting force.
Many Chaos Space Marines contingents favour aggressive, highly mobile tactics, rushing headlong to get to grips with the foe as quickly as possible. Their skill, armour, deadly weapons, genetic enhancements, and mobs of disposable cultists make these reckless charges highly effective.
Warbands of the Chaos Space Marines are more often than not motley assortments of Heretic Astartes, grisly mutants, their cultist thralls. The pitiless masters callously spend the lives of the mortal warriors to buy time for the more valuable Heretic Astartes while simultaneously offering those very same Chaos Space Marines to host the Daemons of the warp.
For ten thousand years, the Chaos Space Marines have waged near-constant war on the galaxy that cast them out. Once the defenders of humanity, the Heretic Astartes have pledged themselves to the Dark Gods. Led by maniacal leaders such as the fanatical Dark Apostle, bitter warbands of Chaos Space Marines roam the battlefield, armed with an array of vicious weapons. Barricades and defenders alike are torn asunder by the devastating heavy armaments wielded by Havocs – and the frenzied swipes of a lumbering Helbrute.
The Ossiarch Bonereapers are one of the Great Necromancer Nagash’s greatest achievements – an elite army of soldiers, crafted from the bones and souls of the dead. These terrible constructs are efficient, loyal, and inexorable, and they grow stronger with every enemy army they defeat, harvesting their very bone-matter in death.
Nagash, Supreme Lord of the Undead is the father of necromancy. Resurrected by dark ritual, the immortal Lord of Death is an awe-inspiring centerpiece miniature.
Orpheon Katakros is the emperor of an undying elite, and he goes to war with all of the pomp and circumstance that befits his station. Distrusting steeds since the disastrous chariot charge that cost him his life, he simply strides to battle with the surety of a god.
Vashtorr is the Soul Forge King, a daemonic demigod of unrestrained invention and abominable artifice. When the Arkifane takes physical form, it is as a horror of pallid flesh stretched over infernal mechanisms, soaring to battle amidst a cloud of lightning and smog. Vashtorr deals destruction with every whirring step, unleashing techno gheist curses upon his foes even as he fashions enhancements for his indentured daemon engines from the raw stuff of realspace.
Heldrakes are winged Daemon Engines that plummet out of the skies like living comets, hurtling towards enemy aircraft and crashing claws-first into them from above.
The Forgefiend is a Chaos Space Marine Daemon Engine that was originally devised to sow death amongst enemy forces from afar.
A Lord Discordant is a machine-obsessed heretic who scuttles across the battlefield atop a Helstalker mount, all the while exuding a palpable aura of anarchy. His mere presence short-circuits machinery not already riddled with daemonic entities – actuators and servos whir erratically, and targeting augurs simply cease to function. The Lord Discordant siphons off the pained spirit of dying vehicles, using the harvested energy to reinvigorate other Daemon Engines or releasing it as a screaming beam to infect the systems of other enemy vehicles. The most famous among the Lords Discordant, Vex Machinator, brought anarchy to the hivesprawls of Vigilus during the War of Nightmares.
