The Horus Heresy

Horus Heresy: Arvus Lighter

Horus Heresy: Deredeo Dreadnought Boreas Configuration

Assault Squads are the rapid attack infantry of the Space Marine Legions. Armed with wargear optimised for close-quarter fighting and hit-and-run tactics, equipped with jump packs that allow them to soar quickly across the battlefield, these squads strike at vulnerable targets or impact the enemy line with shocking force. These abilities make them a devastating tactical asset, as they leap past intervening terrain and fortified positions to engage their adversaries in savage melee combat.

Aethon Heavy Sentinels are a common sight among the ranks of the Solar Auxilia and are most often piloted by grizzled veterans adept at identifying key enemy targets. These robust machines are able to traverse void station interiors and ruined cityscapes with ease, often forming the lynchpin around which many a successful close-quarters assault has swung.

The Solar Auxilia are the most elite division of the Imperial Army, trained and equipped to fight in the most hazardous environments. Their cohorts are recruited from all over the Imperium, drawing on void-born asteroid clans, ambitious noble scions, and underhive scum alike. Whatever their origins, those who display the right combination of aggression, discipline, and skill-at-arms can win glory and greatness by leading the advance of the Imperium's tercios.

The Leman Russ Strike Tanks fielded by the Solar Auxilia are robust armoured vehicles, augmented with Solar-pattern survival systems that allow both tank and crew to operate in the harshest conditions. Squadrons of Strike Tanks are often used to perform wide flanking advances, guided by a Leman Russ Command Tank in order to engage an enemy at the precise moment the cohort's infantry sections launch their own assault.

Solar Auxilia Tactical Command Sections are specialists in battlefield command and control. Led by a Captain or similar sub-commander, these expert sections facilitate the flow of orders, direct the tercios, and co-ordinate artillery and orbital operations. This vital role is mirrored by the junior Line Command Sections who lead frontline troops, while the most powerful and celebrated officers of the Solar Auxilia, known broadly as Legate Marshals, instead go to war with personal guards equipped from their private armouries.

An Age of Darkness has descended upon the galaxy. Horus Lupercal, Warmaster of the Emperor's armies, has turned against his gene-father and sent the Imperium spiralling into bloody civil war. Of the eighteen great Space Marine Legions, finest of all humanity's soldiers, fully half have sided with the traitorous Warmaster, while the remainder stand staunchly loyal to the Emperor. It is a war of brother against brother, Space Marine against Space Marine, which has seen the might of the Imperium's vast armies turned upon itself in a cataclysm of fire and blood.

The Horus Heresy is a conflict of unparalleled destruction, spread across myriad vital campaigns. Embroiled for years in a grinding war of nearly unfathomable scope, the Garmon Cluster now acts as the final break against which the tides of the Warmaster’s forces must crash. Its capital, the Beta-Garmon system, is a burning pyre of armies, where Loyalist forces – led by the Great Angel Sanguinius, the Warhawk Jaghatai Khan, and the remnants of the Shattered Legions – fight to buy precious time before the assault on Terra can begin in earnest.

Ahzek Ahriman has the unique distinction of being both the first and last Chief Librarian of the Thousand Sons, and is the most gifted mystic among their already-formidable psyker corps. A respected commander even before his Legion's reunion with its missing Primarch, Ahriman's keen intelligence and talent in warpcraft soon made him Magnus' foremost apprentice, but his greatest strength is his indefatigable will. Ultimately, this determination would see him play a pivotal role in the Burning of Prospero – and walk strange and terrible paths long after the close of the Horus Heresy.
