Overview 概述
Imperial Preparations 帝国准备
With the Emperor preoccupied with the War Within the Webway and Malcador the Sigillite waging the Shadow Wars, it was left with Imperial Fists Primarch Rogal Dorn to oversee the defences of both Terra and the greater Sol System. The defences of the Imperial Palace were significantly strengthened, and much of its aesthetic was destroyed in favour of strategic defensibility. Following the Schism of Mars, Kelbor-Hal's Dark Mechanicus was victorious in claiming the Red Planet, but an Imperial blockade trapped the traitors on their own world.
由于帝皇忙于网道战争和掌印者马卡多发动的阴影战争，帝国之拳原体罗格·多恩负责监督泰拉和更大的太阳系的防御。皇宫的防御得到了显著加强，其大部分美学被摧毁，转而支持战略防御。在火星分裂之后，凯尔博·哈尔的黑暗机械教在宣称这颗红色星球时取得了胜利，但帝国的封锁将叛徒困在了他们自己的世界里。
As Horus' forces inched closer to Terra, Dorn organized the defenses of the Sol System into a series of Spheres. Each consisted of not only Imperial Fists forces, but also loyalist Imperial Army and Mechanicum. By the closing phase of the battle Dorn held back most of his Astartes forces on Terra in preparation for the siege.
随着荷鲁斯的部队逐渐接近泰拉，多恩将太阳系的防御组织成了一系列层。每支部队不仅包括帝国之拳部队，还包括忠诚的帝国陆军和机械教。在战斗的最后阶段，多恩在泰拉上唤回了他的大部分阿斯塔特部队，为围城做准备。
The First Sphere was the outermost defensive zone from Pluto to Neptune. It was commanded by First Captain Sigismund at Pluto.
第一层是从冥王星到海王星的最外层防御区。它是由冥王星的第一连长西吉斯蒙德指挥的。
The Second Sphere oversaw Uranus. It was commanded by Fleet Master Halbrecht
第二层监督天王星。它由舰队司令哈尔布雷希特指挥
The Third Sphere oversaw the Jupiter region. It was commanded by Seneschal Efried.
第三层负责监督木星区域。它是由埃弗里德总管指挥的。
The Fourth Sphere was commanded by Siege Master Camba Diaz and oversaw the blockade of traitor-occupied Mars This sphere was the largest of the four outer layers of defense, surpassed only by the Terran sphere.
第四层由攻城大师坎巴·迪亚兹指挥，负责监督对叛徒占领的火星的封锁。这个层是四个外层防御中最大的，仅次于泰拉层。
The Fifth Sphere was Terra and Luna, overseen by Primarch Rogal Dorn himself.
第五层是泰拉和月球，由原体罗格·多恩亲自监督。
Initial War 第一次战争
For the next several years, the loyalists would counter traitor-instigated uprisings and attempted breakouts by the Dark Mechanicus on Mars.
在接下来的几年里，忠诚派将对抗叛徒煽动的叛乱和黑暗机械教在火星上的突破企图。
The Alpha Legion announced its entry into the Solar War by exploding the freighter Primigenia over Terra, killing millions by raining debris. This was accompanied by Alpha Legion organized uprisings at Terra's Damocles Starport and Triton. All of this culminated in the first major battle of the Solar War, the Battle of Pluto. The battle saw the Alpha Legion drive on Pluto, linchpin of the loyalist monitoring of the Sol System. During the battle, a fleet of over 200 Alpha Legion warships assaulted the planet, but after Alpharius himself was seemingly killed by Rogal Dorn the traitors retreated. For several years after, the Imperials continually dealt with attempts by the Dark Mechanicum to break out of their cage around Mars as well as Alpha Legion attacks and Cultist activity.
阿尔法军团宣布加入太阳战争，在泰拉上空引爆了货船初诞号，数百万人被倾盆大雨般的碎片炸死。与此同时，阿尔法军团在泰拉的达摩克利斯星港和海卫一组织了叛乱。所有这一切都在太阳战争的第一场主要战斗中达到了高潮，冥王星之战。在这场战斗中，阿尔法军团向冥王星进发，冥王星是忠诚者监控太阳系的关键。在战斗中，一支由200多艘阿尔法军团战舰组成的舰队袭击了这个星球，但在阿尔法瑞斯本人似乎被罗格·多恩杀死后，叛徒们撤退了。几年后，帝国军不断应对黑暗机械教试图突破火星周围围困的企图，以及阿尔法军团的攻击和邪教活动。
Final Phase 最后阶段
In 013.M31 Horus won the massive Battle of Beta-Garmon, giving him access to the strategically important route to Terra. It was now certain that Horus would reach the Throneworld, and Dorn increased his defences with newly arrived Blood Angels and White Scars forces. Dorn and his mostly Human command staff moved their daily headquarters from the Phalanx to the Bhab Bastion of the Imperial Palace. In preparation for Horus' arrival, the Dark Mechanicum on Mars accelerated their breakout attempts and lobbed constant fire from the surface from Mars at a blockade overseen by Captain Camba Diaz. As Horus arrived, Dorn's strategy revolved around holding back and bloodying the traitors as much as possible in the hopes of Roboute Guilliman's inbound reinforcements. The Lord of the Imperial Fists knew his own forces were too meagre to hold back the full might of the traitors, but victory would be assured should they wedge Horus' armada between the forces of Terra and Ultramar. Equally, Horus sought to capture Sol and Terra as quickly as possible before Guilliman could arrive at his rear. To save his Astartes for Terra's defence, Dorn withdrew most large space marine contingents to the Throneworld and relied heavily on Legiones Astartes ships crewed mainly by Humans or Imperial Army vessels for the greater Solar System's defenses.
013.M31荷鲁斯赢得了贝塔·伽蒙之战，这使他能够进入通往泰拉的战略要道。现在可以确定荷鲁斯会到达王座世界，多恩用新来的圣血天使和白色疤痕部队加强了防御。多恩和他的大部分泰拉指挥人员将他们的日常指挥部从山阵号转移到了皇宫的巴布堡垒。为了准备荷鲁斯的到来，火星上的黑暗机械教加速了他们的突破尝试，并从火星表面向坎巴·迪亚兹连长监督的封锁区不断开火。随着荷鲁斯的到来，多恩的战略围绕着尽可能多地遏制和让叛徒流血，以期得到罗伯特·基里曼的增援。帝国之拳领主知道他自己的力量太弱，无法阻止叛徒的全部力量，但如果他们把荷鲁斯的舰队夹在泰拉和奥特拉玛的部队之间，胜利是有保证的。同样，荷鲁斯试图在基里曼到达后方之前尽快占领太阳系和泰拉。为了拯救他的阿斯塔特军团士兵用于泰拉的防御，多恩将大多数大型星际战士特遣队撤回了王座世界，并严重依赖主要由人类或帝国陆军船只组成的阿斯塔特军团舰队来防御更大的太阳系。
The traitor armada finally arrived at Sol on 0000014.M31, the first day of the first month (Primus). As expected by the loyalists the traitors made their initial assaults on the two Warp gates into the system that allowed for the bypassing of Mandeville Points: the Khthonic Gate at Pluto and the Elysian Gate at Uranus. Near-simultaneously, a Sons of Horus armada under Horus Aximand struck at Pluto while an Iron Warriors fleet under Perturabo assaulted the defenses of Uranus, both engaging the Imperial Fists and Imperial Armada defence fleets under Sigismund and Halbrecht respectively. At the same time, an armada of Sons of Horus, Thousand Sons, Word Bearers, and Dark Mechanicum under Ezekyle Abaddon, Ahzek Ahriman, Zardu Layak, and Sota-Nul respectively moved over the galactic disc, bypassing the initial loyalist defenses and striking down into the upper crest of the defensive spheres. The loyalists had foreseen such a ploy and a force of White Scars under Jubal Khan was ready to meet the traitors. Across the Sol System, hundreds of small engagements erupted to make up a naval battle of titanic proportions. Though the loyalists had the advantage of preparations and large amounts of Orbital Defense Platforms and other armored bastions, the traitors had the luxury of overwhelming numbers and Warp-sorcery. In addition, intelligence provided by the Alpha Legion during their earlier attacks proved critical, with Horus having personally been given a map of all loyalist defenses in the Sol System by Alpharius before he departed the traitor war effort at the Ullanor.
叛徒舰队最终于0000014.M31抵达太阳系，即第一月（第一）的第一天。正如忠诚者所料，叛徒们对两个亚空间门进行了初步攻击，进入了允许绕过曼德维尔点的系统：冥王星的赫索尼克之门和天王星的极乐世界之门。几乎同时，荷鲁斯·阿西曼德率领的荷鲁斯之子舰队袭击了冥王星，而佩图拉博率领的钢铁勇士舰队袭击了天王星的防御，分别与西吉斯蒙德和哈尔布雷希特率领的帝国之拳和帝国舰队交战。与此同时，以泽凯尔·阿巴顿、阿扎克·阿里曼、扎度·拉亚克和索塔·努尔分别率领的荷鲁斯之子、千子、怀言者和黑暗机械教组成的舰队越过银河系盘面，绕过最初的忠诚者防御，袭击了防御圈的顶部。忠诚者已经预见到了这样的策略，朱巴可汗领导下的一支白色伤疤部队已经准备好迎接叛徒。在整个太阳系中，爆发了数百场小规模的交战，构成了一场规模巨大的海战。虽然忠诚者有准备和大量轨道防御平台和其他装甲堡垒的优势，但叛徒有压倒性的人数和亚空间魔法的奢侈。此外，阿尔法军团在早期袭击中提供的情报被证明是至关重要的，在他离开乌兰诺的叛徒战争之前，阿尔法瑞斯亲自向荷鲁斯提供了太阳系中所有忠诚者防御的地图。
First Sphere 第一层
At Pluto commanding from the Frigate Lachrymae, Sigismund decimated the initial waves of primarily traitor Imperial Army vessels which arrived through the Khthonic Gate with not only his fleet but also the Moons of the world, which had now been transformed into gigantic gun-fortresses. However as the traitors arrived in ever-increasing numbers the Sons of Horus finally began to appear, using the ships of their allies as shields to begin to fire back. Soon Horus Aximand himself aboard the Battle Barge Throne of the Underworld translated from the Warp, leading a massive push that saw landings on the fortress-moons. Most of the incoming attacks were by savage Newborn Sons of Horus. One by one, the Newborn Astartes boarded the moons and unleashed Scrap Code that either disabled its defenses or turned them to Horus' cause, resulting in the moons beginning to fire on one another. After the moon of Kerberos fell, Sigismund ordered his fleet retreat. The Sons of Horus pursued, walking into the loyalist trap as Sigismund had loyalist Mechanicum Tech-Priests unleash data-jinns into the power reactor complex of the moon. Kerberos exploded, decimating and scattering the pursuing traitor fleet. At this moment, Sigismund had his fleet turn back around and launched a vicious counterattack on the traitors. In an attempt to reverse the situation, Aximand personally led an assault on the Lachrymae to decapitate the loyalist command. In a clash between the Sons of Horus and Sigismund's Templars, Aximand and Sigismund dueled. Horus Aximand slew the Templar Lieutenant Boreas and wounded Sigismund, but the First Captain of the Imperial Fists was able to teleport away aboard the nearby Frigate Persephone, severing one of Aximand's hands as he retreated. Though wounded, Aximand successfully captured the Lachrymae and organized a counterattack that broke the loyalist fleet at Pluto. Sigismund ordered a withdraw towards Terra, informing Rogal Dorn that the First Sphere had fallen after several days of fighting.
在冥王星上，西吉斯蒙德从护卫舰泪痕号指挥，摧毁了最初几批主要是叛徒帝国军队的船只，这些船只不仅有他的舰队，还带着世界的卫星，这些船只已经变成了巨大的炮台。然而，随着越来越多的叛徒到来，荷鲁斯之子终于开始出现，他们用盟友的船只作为盾牌开始反击。很快，荷鲁斯·阿西曼德本人登上了从亚空间传送而来的战斗驳船地下王座号，领导了一场大规模的推进，在堡垒卫星上登陆。大多数即将到来的袭击都是野蛮的荷鲁斯新血发动的。新生的阿斯塔特一个接一个地登上了卫星，并释放了废码，要么使其防御失效，要么将其转向荷鲁斯的事业，导致卫星开始相互射击。冥卫四陷落后，西吉斯蒙德命令他的舰队撤退。荷鲁斯之子紧追不舍，步入了忠诚者的陷阱，西吉斯蒙德让忠诚的机械教技术神甫向卫星的动力反应堆复合结构释放数据精灵。冥卫四爆炸了，摧毁并驱散了追捕的叛徒舰队。此时，西吉斯蒙德的舰队掉头，对叛徒发动了猛烈的反击。为了扭转局势，阿西曼德亲自领导了对泪痕号的袭击，斩首了忠诚者的指挥部。在荷鲁斯之子和西吉斯蒙德的圣殿骑士之间的冲突中，阿西曼德和西吉斯蒙德决斗。荷鲁斯·阿西曼德杀死了圣殿骑士副官波瑞亚斯并打伤了西吉斯蒙德，但帝国之拳的第一连长能够通过附近的护卫舰珀尔塞福涅号远程传送，在撤退时切断了阿西曼德的一只手。虽然受伤，但阿西曼德成功俘获了泪痕号，并组织了一次反击，摧毁了冥王星的忠诚舰队。西吉斯蒙德下令向泰拉撤退，通知罗格·多恩，经过几天的战斗，第一层已经沦陷。
Second Sphere 第二层
At Uranus, Perturabo himself from the Iron Blood oversaw a massive traitor onslaught of over 4,000 vessels through the Elysian Gate on Halbrecht's Second Sphere Fleet and orbital defenses. Commanding the Battle Barge Monarch of Fire, Halbrecht's fleet took a ranged approach, sniping from the screen of 27 fortress-moons and hundreds of gun-platforms into the arrival points of Iron Warriors vessels with their Nova Cannons. Enormous space-minefields hindered the traitor fleet, boxing them into these killzones. Perturabo rammed three enormous mass-conveyor vessels known as Alekto, Megaera, and Tilphousia into the loyalist fleet of gun-platforms, using them as Fire Ships and wiping out many of the defenders. With the way to the inner core of Uranus' defenses cleared, Perturabo fielded an enormous Space Hulk known as the Daughter of Woe which unleashed hell on the loyalists with its enormous array of weaponry. One by one the remaining defensive bastions of Uranus fell to the Iron Warriors onslaught, with the firepower from the Daughter of Woe devastating the moons Umbriel, Cordelia, and Oberon. As the Iron Warriors closed the distance with the loyalist defensive bastions, they unleashed transports filled with millions of drug-fueled Gangers, Pirates, Mutants, and Cultists into their bowels. The defending forces, mostly Imperial Army and Servitors, fought valiantly but were overwhelmed by sheer numbers. After a delaying maneuver that bought another 36-hours for the loyalists, Halbrecht ordered a retreat towards Terra. He brought with him the majority of the Second Sphere Fleet, saved in order to bloody the traitors in future engagements. The Second Sphere had fallen.
在天王星，来自铁血号的佩图拉博亲自监督了4000多艘船只通过极乐世界之门对哈尔布雷希特的第二层舰队和轨道防御系统的大规模叛徒袭击。哈尔布雷希特的舰队指挥着火焰君王号战斗驳船，采取了远程方法，从27个堡垒卫星和数百个炮台的屏障上，用新星炮狙击到钢铁勇士船只的到达点。巨大的太空雷区阻碍了叛徒舰队，将他们围困在这些杀戮区中。佩图拉博将三艘名为阿勒克托、墨纪拉和提西福涅的大型运输船撞向了忠诚者的炮台舰队，将其用作火船，消灭了许多防御者。随着天王星防御核心的清除，佩图拉博派出了一艘被称为“灾难之女”的巨大太空废船，用其庞大的武器阵列向忠诚者释放了地狱。天王星剩下的防御堡垒一个接一个地被钢铁勇士的猛攻摧毁，灾难之女的火力摧毁了卫星天卫二、天卫六和天卫四。当钢铁勇士与忠诚者的防御堡垒拉近距离时，他们释放了装满数百万吸毒的黑帮、海盗、变种人和邪教徒的运输工具。防御部队，主要是帝国陆军和机仆部队，英勇作战，但被庞大的兵力所淹没。经过一次拖延战术，为忠诚者又争取了36个小时，哈尔布雷希特下令向泰拉撤退。他带来了第二层舰队的大部分，为了在未来的战斗中血腥镇压叛徒而保存下来。第二层已经陷落。
Third Sphere 第三层
With the Second Sphere reduced, there were still thousands of pockets of resistance between Uranus, Neptune, Saturn, and outer Jupiter and their accompanying moons and orbitals. To speed up the conquest of Sol, Perturabo unleashed waves of Pirate, Emperor's Children, and Night Lords vessels as well as ships of Traitor Space Marines which had since taken new colors or names. Though Titan had been cloaked in a ritual by Malcador for a future project, the rest of Saturn and Neptune were terrorized by these vicious bands of killers while Perturabo and Forrix led an assault on Jupiter itself, which was defended primarily by Imperial Fists, Imperial Army, and Blood Angels vessels under Captain Efried. In addition, the majority of the Second Sphere Fleet which had been held from the battle at Uranus were finally committed to the battle. Efried and Halbrecht's fleets slowly gave ground to the Iron Warriors in the vast expanse of Jupiter and her moons, eventually being forced to withdraw to Terra once the overall situation in the Sol System collapsed.
随着第二层的缩小，天王星、海王星、土星和外木星及其伴随的卫星和轨道之间仍有数千个障碍区。为了加快对太阳系的征服，佩图拉博释放了海盗、帝皇之子和午夜领主的战舰，以及叛徒星际战士的战舰，这些战舰后来换上了新的颜色或名字。尽管泰坦已经被马卡多为未来的项目披上了仪式的外衣，但土星和海王星的其他部分都被这些恶毒的杀手团伙吓坏了，而佩图拉博和弗里克斯则领导了对木星本身的攻击，木星主要由埃弗里德连长率领的帝国之拳、帝国陆军和圣血天使战舰进行防御。此外，在天王星之战中被控制的第二层舰队的大部分最终都投入了战斗。埃弗里德和哈尔布雷希特的舰队在广阔的木星及其卫星上慢慢向钢铁勇士让步，一旦太阳系的整体局势崩溃，最终就会被迫撤退到泰拉。
Fourth & Fifth Spheres 第四&第五层
Amid the carnage erupting across the outer Sol System, Horus' most important maneuver came above the galactic disc. The combined Sons of Horus, Thousand Sons, Word Bearer, and Dark Mechanicum fleet plunged into the void between Terra and Mars. This force split then split in half, with the larger Dark Mechanicum contingent making for Mars while the Traitor Astartes force moved towards Luna. Along the way to Luna, Abaddon's armada was continually harried by the White Scars under Jubal Khan. However Abaddon and Zardu Layak were eventually able to board the White Scars flagship Lance of Heaven and slay Jubal in combat. At Mars, the large Dark Mechanicum fleet drawn from hundreds of treacherous Forge Worlds plowed into Camba Diaz's blockade fleet. Consisting of large numbers of Imperial Fists, Blood Angels, loyalist Mechanicum, and Imperial Army, this force was the largest of the four outer spheres and a vicious battle erupted over the Red Planet. From the Battle Barge Fortress of Eternity, Camba Diaz had to deal with attacks on both sides of his fleet as Kelbor-Hal's besieged Martian forces launched their own attack in conjunction with the arriving Dark Mechanicum armada. Understanding the time for a counterattack had arrived, Dorn and his command staff moved to the Phalanx, which finally left Terra's orbit and intended to contest the traitors at Luna and then Mars. Jaghatai Khan stated that the traitors had failed, as Horus' main fleet had yet to show itself and the firepower of the Phalanx would blunt this new attack, buying the loyalists enough time for Guilliman's arrival.
在外太阳系爆发的大屠杀中，荷鲁斯最重要的动作出现在星系盘上方。荷鲁斯之子、千子、怀言者和黑暗机械教舰队联合潜入了泰拉和火星之间的虚空。这支部队随后分裂成两半，较大的黑暗机械教部队前往火星，而叛徒阿斯塔特部队则向月球移动。在前往月球的途中，阿巴顿的舰队不断受到朱巴可汗领导下的白色伤疤的骚扰。然而，阿巴顿和扎杜·拉亚克最终登上了白色伤疤旗舰“天堂之枪”，并在战斗中杀死了朱巴可汗。在火星上，来自数百个危险的铸造世界的大型黑暗机械教舰队冲入了坎巴·迪亚兹的封锁舰队。这支部队由大量的帝国之拳、圣血天使、忠诚的机械教和帝国军队组成，是四个外层防御中最大的一个，在这颗红色星球上爆发了一场激烈的战斗。从战斗驳船永恒要塞号出发，坎巴·迪亚兹不得不应对他的舰队两侧的攻击，因为凯尔博·哈尔被围困的火星部队与抵达的黑暗机械教舰队一起发动了自己的攻击。知道反击的时间到了，多恩和他的指挥人员转移到了山阵号，山阵号最终离开了泰拉的轨道，打算在月球和火星与叛徒作战。察合台可汗表示，叛徒失败了，因为荷鲁斯的主要舰队尚未出现，山阵号的火力将削弱这次新的攻击，为基里曼的到来为忠诚者争取足够的时间。
Rogal Dorn battles Samus 罗格·多恩与萨姆斯战斗
Meanwhile, Ahzek Ahriman's Thousand Sons force, accompanied by Word Bearers and their cultist-slaves under the Apostle of the Unspeaking, moved on The Comet between Venus and Terra, capturing it from light Servitor defenses and beginning a great sacrificial ritual prepared on the orders of Lorgar years prior. The ritual depended on an absolute timetable, having to be initiated at a precise celestial alignment in the Sol System that had not been seen since the Age of Strife. As Ahriman and the Word Bearers conducted their ritual, Abaddon's remaining Sons of Horus contingent emerged over Luna. The moon's defensive ring sported defenses greater than entire Expeditionary Fleets, and with the Phalanx inbound Abaddon's relatively small fleet seemed doomed to a quick death. However at the exact moment that Ahriman's ritual on The Comet was reaching its crescendo, Abaddon plunged his Battle Barge War Oath into the defensive ring around Luna as he and his warriors teleported aboard the moons surface. The kamikaze attack blew a 20 kilometer long gap into Luna's defensive ring as Ahriman departed The Comet, which became an epicenter for a massive black scar in reality which briefly blocked out the sun itself. From this tear in realspace came tens of thousands of traitor vessels including the full might of the World Eaters, Thousand Sons, and Emperor's Children. Besides conventional warships, this force also included hordes of winged Daemons. At the head of this impossibly vast armada's head was Angron standing atop the battlements of the Conqueror, Fulgrim aboard the Pride of the Emperor, and Horus himself commanding from the Vengeful Spirit. The new arrivals struck towards Luna, annihilating and scattering Battlefleet Solar and the Lunar defensive network. On Luna's surface, a Justaerin and Word Bearers assault under Abaddon and Layak eventually succeeded in securing the coveted Selenar Gene-Seed technology that had been used to create the original Astartes. The presiding Selenar Matriarch, Heliosa-78, ultimately chose to side with Horus than carry out her orders from Dorn to destroy her precious gene-tech before it could fall into traitor hands.
与此同时，阿扎克·阿里曼·的千子部队，在使徒无言者的带领下，在怀言者和他们的邪教奴隶的陪同下，在金星和泰拉之间的彗星上移动，将其从光亮的机仆防御中捕获，并开始了多年前根据珞珈的命令准备的伟大祭祀仪式。仪式取决于一个绝对的时间表，必须在自纷争时代以来从未见过的太阳系中精确的天体对齐处启动。当阿里曼和怀言者进行仪式时，阿巴顿剩下的荷鲁斯之子部队出现在月球上空。月球的防御圈比整个远征舰队的防御能力更强，随着山阵号的进入，阿巴顿相对较小的舰队似乎注定要迅速死亡。然而，就在阿里曼在彗星上的仪式达到高潮的那一刻，阿巴顿和他的战士们在月球表面传送时，将他的战斗驳船战争誓言号投入了月球周围的防御圈。当阿里曼离开彗星时，神风特攻队的袭击在月球的防御圈中炸出了20公里长的缺口，彗星实际上成为了一个巨大的黑色裂隙的中心，该裂隙短暂地遮挡了太阳本身。从现实世界的撕裂中，数以万计的叛徒船只出现了，其中包括吞世者、千子和帝皇之子的全部力量。除了常规战舰，这支部队还包括成群的有翼恶魔。这支庞大得不可思议的舰队的首领是站在征服者号城垛上的安格隆、登上帝皇之傲号的福格瑞姆和从复仇之魂号指挥的荷鲁斯本人。新来者向月球进发，消灭并驱散了太阳舰队和月球防御网。在月球表面，阿巴顿和拉亚克率领的加斯塔林和怀言者的进攻最终成功地获得了令人垂涎的赛琳娜基因种子技术，该技术曾被用于制造最初的阿斯塔特。赛琳娜主母赫利奥萨-78最终选择站在荷鲁斯一边，而不是执行多恩的命令，在她珍贵的基因技术落入叛徒手中之前摧毁它。
Dorn attempted to organize a counterattack aboard the Phalanx, but another one of Horus' trump cards took effect. The Remembrancer Mersadie Oliton, who had been brought aboard the battlestation by Garviel Loken due to an urgent need to speak to the Primarch, was revealed to have been unknowingly corrupted by Maloghurst years prior. From a warp-eye placed on her, the Daemon Samus emerged directly into the bowels of the Phalanx. Dorn's own command bridge was assailed by both Daemonic hordes and Samus' madness and in desperation the Primarch unleashed his Librarians which had been interred aboard the station since the Council of Nikaea. Not even the arrival of Sigismund's reinforcements from Pluto could turn the tide. Dorn fought Samus himself, but every time the Daemon died he was reborn by possessing one of the many nearby corpses. To end Samus' rampage, a distraught Oliton threw herself into the Phalanx reactor chamber, with her death closing the portal from which the Daemons were able to manifest. Though the Phalanx was now secure, victory in the Sol System was now impossible. Luna had fallen, Mars was rapidly being relieved, and Horus' armadas were closing in all around them. Dorn ordered that the Imperial Army Admiral Niora Su-Kassen take the Phalanx out into the outer Solar System in order to save it from certain destruction while he returned to Terra aboard Sigismund's Frigate Persephone. The surviving loyalist vessels in Luna's orbit either fled into the void or docked in Terra's atmosphere.
多恩试图在山阵号上组织反击，但荷鲁斯的另一张王牌奏效了。由于迫切需要与原体交谈，加维尔·洛肯将纪述者梅赛蒂·奥列顿带上了战斗空间站，据透露，她在几年前被马洛赫斯特不知不觉地腐化了。从放在她身上的亚空间之眼，恶魔萨姆斯直接出现在山阵号的内部。多恩自己的指挥舰桥受到了恶魔部落和萨姆斯疯狂的攻击，在绝望中，原体释放了自尼凯亚会议以来一直在空间站上的智库。即使西吉斯蒙德从冥王星增援，也无法扭转局势。多恩亲自与萨姆斯作战，但每次恶魔死后，他都会通过占据附近许多尸体中的一具而重生。为了结束萨姆斯的暴行，心烦意乱的奥列顿将自己扔进了山阵号的反应堆室，她的死亡关闭了恶魔能够显现的入口。虽然山阵号现在很安全，但在太阳系中取得胜利现在是不可能的。月球已经沦陷了，火星正在迅速被解放，荷鲁斯的舰队正在向他们周围逼近。多恩命令帝国海军上将尼奥拉·苏-卡森将山阵号带到外太阳系，以便在他乘坐西吉斯蒙德的护卫舰珀尔塞福涅号返回泰拉时将其从某些破坏中拯救出来。在月球轨道上幸存的忠诚者战舰要么逃到虚空中，要么停靠在泰拉的大气层中。
Aftermath 余波
With the Solar System now in his hands, Horus was finally able to strike at the Throneworld itself. After a little over a month of fighting, on the Thirteenth day of Secundus the first orbital strikes from Horus' fleet fell upon Terra. The Siege of Terra had begun.
随着太阳系的掌握，荷鲁斯终于能够攻击王座世界本身。经过一个多月的战斗，在第二的第十三天，荷鲁斯舰队的第一次轨道打击落在了泰拉上。对泰拉的围攻已经开始。
