"For the warrior, the only crime is cowardice."
The Justaerin were one of two distinct sub-formations within the elite 1st Company of the Luna Wolves and later the Sons of Horus Legion. Led by the Legion's First Captain Ezekyle Abaddon, the Justaerin were the pride of the XVI Legion, sporting their signature black armour, which denoted their specialisation in harrowing actions, shock assaults and strategic decapitation strikes. Tasked with forming the "point of the spear" for the XVI Legion, they went where the fighting was thickest, their attack directed usually at destroying the heart of an opposing target or conducting the decapitation strike of an enemy force. Early proponents of the use of Tactical Dreadnought Armour, many Justaerin entered combat as Terminators, relying on the resilience this gave them to smash aside any resistance and close in for the kill.
Notable Justaerin Members
- Ezekyle Abaddon - First Captain Ezekyle Abaddon was fanatically loyal to Horus and one of the foremost warriors of his Legion and commander of the elite Justaerin Terminators. A hulking brute of a Space Marine, given his size and appearance there had long been whispered rumours within the Sons of Horus Legion that he was the direct clone-progeny of the Warmaster himself. In truth, Abaddon echoed his Primarch in many ways, not least in his savage power as a fighter and skill as a tactician which gave him the greatest tally of victories of any within the Sons of Horus bar his Primarch. Once regarded as a hero of the Imperium, Abaddon was first and foremost devoted to Horus always, and walked willingly into damnation with his master. Soon his name became among the most feared and despised of those who had turned Traitor. On Istvaan III, Abaddon took the field of battle and was personally responsible for slaying many of his former comrades who remained loyal to the Emperor. After the Heresy, it was Abaddon, now named Abaddon the Despoiler, who would rise to replace Horus as the Chaos Lord and commander of the reborn Black Legion and the Warmaster of Chaos Undivided. Viewing Horus now with contempt for his failure to defeat the Emperor of Mankind during the Battle of Terra, Abaddon dedicated himself to winning the Long War against the Imperium and winning the prize for himself that had been denied to his gene-father. To this end, Abaddon became the primary force behind the Black Crusades which periodically spill out of the Eye of Terror to threaten Imperial space.
- Falkus Kibre, "Widowmaker" - Falkus Kibre, known as the "Widomaker," was a Captain of the elite 1st Company who led the black-armoured Terminator Squad known as the "Widowmakers" of the elite Justaerin, Horus' personal honour guard. Following the Warmaster's fall to Chaos and turn from the light of the Emperor, Kibre willingly followed his Primarch into damnation during the Horus Heresy. He led the Justaerin during some of the most infamous campaigns during this period of upheaval and rebellion, including the Drop Site Massacre on Istvaan V and the Battle of Terra. Following the dissolution of the Mournival with the losses of Captains Loken and Torgaddon on Istvaan III during the conflict between the Traitors and Loyalists within the Sons of Horus, Horus Aximand suggested the reformation of the Mournival, proposing to First Captain Abaddon that Kibre be one of its members. Kibre was eventually recommended to become a member of the Mournival by First Captain Ezekyle Abaddon following the Battle of the Mausolytic Precinct on the planet Dwell to replace the Mournival members who had been lost. Ten millennia later, Kibre still serves Abaddon, the new Warmaster of Chaos, as part of the Black Legion's Terminator elite.
