The Foresworn are a large warband of Chaos Space Marines drawn from the World Eaters Traitor Legion. The corrupted Astartes of this warband are all Khornate Berserkers. The Foresworn are led by the infamous Chaos Lord Kossolax the Foresworn.
- First War for Armageddon (444.M41) - The Daemon Primarch Angron, the favoured Champion of Khorne, reunified his World Eaters after the Battle of Skalathrax, and led the XII Legion once again deep into the heart of the Imperium when he launched the invasion of the Hive World of Armageddon in 444.M41, in a lesser known conflict that would come to be known as the First War for Armageddon. Kossolax led his warband of Khornate Berserkers, the Foresworn, in a bloody campaign of slaughter across the doomed planet. But in the end, victory was denied to the Forces of Chaos due to Angron's own foolish belief in his victory before completing a total conquest of the world and the successful intervention of the Grey Knights Chapter of Space Marines. The Grey Knights assault banished Angron back to the Warp for a one hundred standard years and led to the failure of the overall campaign. During the World Eaters' withdrawal a portion of the Foresworn warband was left behind on Armageddon.
- 13th Black Crusade (999.M41) - The Foresworn was a part of the Forces of Chaos gathered under the leadership of the Warmaster of Chaos, Abaddon the Despoiler, during the infamous 13th Black Crusade. This resulted in the largest mobilisation of both Imperial and Chaotic forces seen in the Milky Way Galaxy since the bygone era of the Horus Heresy.
- Assault on Agripinaa (999.M41) - Due to its proximity to the Cadian Gate, the Forge World of Agripinaa suffered greatly during Abaddon the Despoiler's 13th Black Crusade. This world was invaded by Kossolax the Foresworn and his large warband of Khornate Berserkers, who sacrificed millions of its citizens over 40 hours to summon a horde of Khornate daemons, which included a mighty Bloodthirster. Four companies of the Blood Angels Chapter answered the call to defend Cadia, arriving towards the middle of the conflict. A significant force of Blood Angels immediately fell upon the Chaos hordes assaulting Agripinaa, seeking out the leader of the attacking forces, the notorious Champion of Khorne -- Kossolax the Foresworn. In an epic confrontation likened to the mythic conflict between the Blood Angels' Primarch Sanguinius and the mighty Bloodthirster Ka'Bandha at the closing of the Ultimate Gate during the height of the Horus Heresy at the Battle of Terra, the Blood Angels took the fight directly to the enemy. Kossolax, fully aware that his bodyguard was no match for the frenzied Sons of Sanguinius, called upon the slavering daemons of Khorne for aid. The summoning rite was an act of wanton, traitorous carnage, as the Chaos Champion ordered his World Eaters to sacrifice the lives of their Chaos Cultist allies in order to gain the favour of the Blood God. Uncounted thousands were slaughtered in mere hours, their blood flowing in rivers through the corridors of Agripinaa's primary hive city. The sacrifice had the desired result, and as the first of the Blood Angels' Veteran Assault Squads soared into battle, a blasphemous avatar of the Blood God ripped its way through the skein of reality to confront the Sons of Sanguinius. At the height of the battle, the Blood Angels' Sanguinary High Priest, Brother Numitor, confronted the Bloodthirster, and dealt it a blow that stunned it for a brief moment. Seizing the advantage, the brothers of the Death Company leapt upon its back, but the daemon recovered, and severed Numitor's arm with a crack of its long whip. The priest was holding one of the Blood Chalices bearing the sacred vitae of the Chapter's Primarch, and the blessed liquid was spilled across the tarnished paving. At that moment, a deathly still overcame the scene, the Blood Angels momentarily shocked beyond action at the sight of their Primarch's blood seeping into the ground. Then, the silence was broken, as Numitor staggered to his feet and bellowed the words of the Rite of Exsanguination. The assembled brethren of the Death Company were overcome with visions of the last time their Primarch's blood had been spilt by a servant of Chaos, when Sanguinius had fallen at the hands of the Arch-Traitor Horus. The Death Company went berserk. They hacked down the Bloodthirster in a savage, rage-fuelled frenzy, oblivious to the fact that it dragged half their number down with it, before turning their hatred upon the warband of Kossolax the Foresworn. The World Eaters were expelled from Agripinaa at great cost to the Blood Angels, though the annals of the Chapter's history will long celebrate the casting out of the Greater Daemon. The warlord Kossolax was not found at the hive city, and the Sanguinary High Priest Numitor has vowed to hunt him down, no matter the cost.
Notable Foresworn Members
- Kossolax the Foresworn - Ordo Malleus records states that the individual known as Sergeant Solax of the World Eaters' 3rd Assault Company before the Horus Heresy, is thought to be the beast now known as Kossolax the Foresworn. If this is indeed the case, Sergeant Solax has risen to the command of an entire company of Khornate Berserkers known as the Foresworn. It is believed that he fought at the climax of the of the Heresy in the siege of the Imperial Palace during the Battle of Terra.
- Hrothqar Furor – Hrothqar Furor, known as the Ravager of Worlds, is the Champion of Khorne who served as Kossolax's lieutenant. During the First War of Armageddon, when the World Eaters were driven off the planet by Imperial forces, a portion of the Foresworn were left behind. Furor killed the acting warband leader in a death-duel and assumed command of this band of Bersekers. Furor had served in the warband of Kossolax the Foresworn in eight campaigns against the Imperium of Man.
- Isakar Savagehand – Isakar Savagehand was the celebrated Slaughterer of Kairn, who slices through his enemies with the obsidian blades of his Lightning Claws.
- Volkarr, the Herald of the Skull Lord – Volkarr was able to blow a resounding funereal note on the brass carynx horn that was forever welded to the faceplate of his armoured helmet. The mournful sound cuts through the din of battle, grasping the lap-dogs of the "False Emperor" in the stifling grip of fear but, at the same time, filling the devoted of Khorne with renewed vigour, sending their overwrought minds into a frenzy of blood-letting and limb-lopping.
- Baruch – A full head taller than any of the other Chaos Space Marines of the Foresworn, Baruch's Warp-charged body is barely contained by his ancient Power Armour, his bulging, muscled arms bare of armour as he tears his enemies limb-from-limb with his bare hands.
- The Reaper – An insane mutant creature that was once a World Eaters Chaos Space Marine, The Reaper's allegiance to Khorne is marked by a skull-rune brand that is repeated all over its filthy, bristle-haired flesh. It often drags its gore-clogged talons through the bodies of its foes and rips the throats from them with slavering, shark-like teeth.
- Zalel Eazar – This Possessed Chaos Space Marine's sutured skin ripples with the daemonic essence of the entity he had invited to share his physical form.
- Brother Orrax – Orrax was the bearer of the damned Khornate icon known as the Eye of Kharnath.
- Khorgha the Chosen – Khorgha the Chosen was an Aspiring Champion of Khorne who preferred to slaughter his enemies with a Dread-Axe.
The Foresworn are known to possess a fleet of significant size which deployed to support the Forces of Chaos' naval operations during the 13th Black Crusade. The Foresworn's fleet includes the following types of starships:
The Foresworn's badge is the same as that of their parent Traitor Legion, the World Eaters, which is a fanged maw engulfing a world. Some versions omit the world, instead only using the large, fanged maw.
