Changes

Kossolax was originally [[Space Marine Sergeant|Sergeant]] of the World Eater's 3rd Assault Company known as '''Solax'''. He had been trained on [[Bodt]], took part in the [[Ghenna Massacre]], and then betrayed his brothers at [[Isstvan III]]. An unremarkable officer who never rose particularly high, Kossolax Solax survived the Heresy all the way to the [[Siege of Terra]]. However following Angron's defeat to [[Sanguinius]] and the death of [[Horus]], the traitor invasion of Terra broke. It was then that Solax's Captain{{fn|6d}}{{fn|6b}} There, his [[ShâhkaRhino]], abandoned his brothers and retreated from orbit with the transporter ''[[Conqueror Barbarus (ShipRhino)|ConquerorBarbarus]]''. was documented by the Imperium; this sighting later allowed the Imperials to identify Solax as "Kossolax led his brothers in a desperate retreat and never forgave Shâhka for the betrayal".{{fnFn|6d1}}

Kossolax's origin as Sergeant Solax in Imperial histories largely based on sightings of the ''However, following [[Barbarus (Rhino)|BarbarusAngron]]'', a s defeat to [[RhinoSanguinius]] transporter which belonged to Solax's squad and was reportedly present during the death of [[Battle of Terra|Siege of the Imperial PalaceHorus]] at , the height traitor invasion of Terra broke. Solax and his comrades escaped from Terra, but they were relentlessly pursued by the Heresyloyalists. Since It was thenthat Solax's Captain, [[Shâhka]], took the ''Barbarus[[Conqueror (Ship)|Conqueror]]'' has been spotted and fled, leaving most of the 3rd Assault Company behind to die on numerous occasions throughout another ship. Solax led his brothers in a desperate retreat and never forgave Shâhka for the millennia in service of Kossolaxbetrayal.{{Fnfn|16e}}

Following the SiegeAfter Shâhka's desertion, Solax emerged as Acting-Captain of the 3rd Company and commander of the ''[[Furious Aggression]]''. After discovering the world [[Skalathrax]], Solax opposed the [[Devourers|Devourer]] [[Goghur]]'s desire to attack the [[Emperor's Children]], warning that he would lead the 3rd Company from the system at the first sign of aggression by Goghur.{{Fn|7a}} Solax was later part of [[Khârn]]'s deputation that met with the Emperor's Children.{{Fn|7b}} His misgivings over an attack on Skalathrax were ultimately proven correct, as the [[Battle of Skalathrax]] broke the World Eaters Legion.{{fn|6e}}{{Fn|7a}}{{fn|8}} Solax held a low opinion of both Khârn as well as Angron for destroying the World Eaters' unity during the Heresy and at Skalathrax.{{fn|6d}}{{fn|6e}}

Eventually, he became a powerful [[Chaos Lord]] in his own right thought like [[Abaddon]] believed himself able to resist madness and full corruption by Chaos. He took the name "Kossolax the Foresworn", killing anyone who kept using the name "Solax".{{Fn|6d}} Distrusting the sanity and ambition of most of his gene-brothers, Kossolax began to recruit and breed human mutants as followers; these became his guards, bondsmen, and technicians. Though he continued to employ some World Eaters as advisors, he largely relied on the mortal mutants to manage his resources and logistics.{{fn|6e}}{{Fn|6f}}

Though the forces of [[Khorne]] overwhelmed the [[Armageddon|planet]] and caused a bloodbath, their hold was ultimately broken. Angron and his [[Daemon]]ic minions were banished and the warriors of Khorne repelled. During their withdrawal a part of the Foresworn warband was left back on Armageddon.{{Fn|4}} However, Kossolax was able to capture the ''[[Conqueror (Ship)|Conqueror]]'' after the First War for Armageddon, allowing him to further expand his warband and power.{{Fn|6d}}

After the destruction of [[Cadia]], Kossolax led the ''[[Conqueror (Ship)|Conqueror]]'' at the head of a large Chaos fleet that included World Eaters, [[Night Lords]], [[Death Guard]], [[Thousand Sons]], and [[Black Legion]] [[Battle of the Agripinaa System|to attack]] [[Agripinaa]].{{Fn|5}} This operation was part of the [[13th Black Crusade]] of [[Ezekyle Abaddon|Abaddon the Despoiler]]. Kossolax's forces landed on Agripinaa, where they were confronted by the [[Blood Angels]] led by the [[Sanguinary High Priest]] [[Numitor (Blood Angels)|Numitor]]. In order to turn the tide of the battle, he ordered his berzerkers to fall upon their allied [[cultist]] hordes. The massacre that ensued was enough to summon a mighty [[Bloodthirster]] who dealt heavy losses to the Blood Angels and their [[Death Company]]. Although they managed to overcome the daemon and drive the World Eaters from the planet, Kossolax was not slain. Seeking vengeance, Numitor vowed that he would hunt him down, no matter the cost.{{Fn|3}}

Following the destruction of Cadia, Kossolax's power grew even greater as massive numbers of World Eaters and other assorted traitors joined his forces. Declaring himself the '''Lord Regent''' of his former Legion, he led his growing force to plunder the [[Imperium Nihilus]] instead of supporting Abaddon's continued attacks on Terra. Eventually, he launched an invasion of the heavily defended Imperial world [[Kalkin's Tribune]].{{Fn|6d}} As this battle still raged, Kossolax's grand ambitions were seemingly thwarted when [[Angron]] himself manifested aboard the ''[[Conqueror (Ship)|Conqueror]]'' and the vessel's combative [[Machine Spirit]] that had once been [[Lotara Sarrin]] pledged itself to the Daemon PrincePrimarch.{{Fn|6a}} Similarily, most World Eaters of Kossolax's fleet instinctively devoted themselves to Angron or went insane. Initially driven to rage and despair, Kossolax instead began to see the bestial Primarch as an opportunity to fully place the World Eaters under his command. Showing little interest in leadership, Angron instead would dwell in the bowels of the ''Conqueror'' until unleashed to murder a world. Kossolax used the Primarch's return to greatly swell his numbers, attracting more followers by posing as Angron's herald and spokesman.{{Fn|6b}}
