The '''{{PAGENAME}}''' was a battle of the [[Horus Heresy]]in which three independent loyalist forces attacked the [[Xana System]] as it concluded negotiations for alliance with the traitors.

==Overview==Fought in 009.[[M31]], it began when [[Terra]] received word that the renegade [[Forge World]] of [[Xana]] on the western fringes of the [[Imperium]] reached an accord with [[Horus]] to supply his armies. The bargain was said to have been sealed with the delivery of three new [[OrdinatusUlator]] weapons. In what became {{fn|1}} The [[Amphion (Warship)|Amphion]], a suicide mission[[Gloriana Class Battleship]], led an armada of five capital ships against Xana's formidable orbiting fleet as a handpicked force distraction, while a [[Callidus Assassin]] under the guise of the [[Davin]]ite priest [[Unvacar Noon]] sought to assassintate [[Space MarinesRaxhal Karaddon]], including many the [[BlackshieldsSons of Horus]]commander sent to collect the weapons, were dispatched to destroy disrupt the war machines deal and drive a wedge between convince Xana and to return to the Traitors under [[Raxhal Koraddon]]Imperial fold.{{Fnfn|12}}

The attack began when Karaddon's warship, the ''Cicatrice Tyrannis'', was intercepted on the edge of the system by [[AmphionEndryd Haar]], a and his warband of [[Gloriana Class BattleshipBlackshields]], led an armada of five capital ships against Xana's formidable orbiting fleet who masqueraded as Koraddon's ship ''Cicatrice Tyrannis'' landed the warlord Karaddon and his honour guard in an attempt to steal the Ordinatus engines.{{fn|2}} They arrived in the midst of the battle, landing to meet traitor [[Archmagos]] [[Gilim Raijan]]. Xana {{fn|1a}} 'Noon' had previously spoken to the real Karaddon and noticed that his voice was different, refraining from assassinating him until his purpose was known.{{fn|2}} Raijan, confident that the Imperial attack would be fended off, readied an army of explosive-collared captives to use against as a demonstration of the loyalists. Many effectiveness of these slaves were killed by [[the Ordinatus Ulator]]'s as a demonstration by Xana to Koraddon.{{Fn|1a}}

Meanwhile in space, the Imperial warships were aided by the sudden arrival of the [[Dark Angels]] warship ''[[Dark Sovereign]]'', which swept aside the traitor system orbital stationsand destroyed much of the supply fleet of macro-transports above Xana I. The ''Dark Sovreign'' then launched Dark Angels Legionaries, [[Blackshields]] under [[Endryd Haar]], and [[Shattered Legions]] warriors at targets across the Xana System. {{fn|1a}} Enragedat the prospect of the Ordinatus engines being seized by another force, Koraddon tore Haar ripped Archmagos Raijan's head and confronted 'Noon', who revealed himself as an agent of [[Malcador (Character)|Malcador]], whose ultimate goal was to recover weapons for the defence of [[Terra]] from its shoulders before departinga secret weapons facility under the prison-[[forge]] of [[Xana-Tisiphone]]. Haar agreed to serve the Sigillite for a chance to truly hurt the Warmaster, killing members of his own warband who disagreed. [[Erud Vahn]] disabled the collars on the prisoners used in the 'false war', allowing them to fight back against their captors.{{fn|2}} The surviving members of Haar's honour guard captured the Ordinatus Ulator and ransacked Xana-Tisiphone as the remainder of the Blackshield company aboard the ''Cicatrice Tyrannis'' commenced a ground assault. {{fn|1a}} The loyalists Dark Angels and Shattered Legions fought through waves of Dark Mechanicus [[Battle Automata]] and [[Adsecularis]] before destroying much of the Forge forge complexes of Xana II. Haar's Blackshields withdrew aboard the ''Cicatrice Tyrannis'' after a counter attack of advanced and capturing 2 unfamiliar patterns of [[Battle-Automata]] emerged from the Sheaol penitentiary and destroyed the 3 OrdinatusUlator ''Nepothax'' in an attempt to recapture it. {{fn|1a}} In the aftermath of the battle, Xana's alliance with Horus was heavily delayed and they undertook raids against both Imperial and traitor assets.{{Fn|1a}} A possible side-effect of the raid was the release of the fallen [[Magos Dominus]] [[Anacharis Scoria]], who would eventually seize Xana and turn it into the first of the Hell-Forges.{{fn|1b}}
