M30.862: After the cleansing of Circlet-Morse, the Xenos Race reorganized and expanded in just thirty short years. Their ability to imitate and adapt almost nullified the Imperium's technological and tactical advantages.
The entire Xenos Race Alliance gathered even larger slave armies, more elite "Overlord" warriors whose performance rivaled that of the Astartes, and complex fleets commanded personally by the Shloth race, launching a full-scale assault on human colony worlds in the northern and eastern The Galaxy / Milky Way.
In the northeastern The Galaxy / Milky Way, the Xenos Race launched its first wave of attacks. Imperial worlds fell one after another, and entire expeditionary fleets and colony fleets vanished without a trace after engaging the Xenos Race fleet.
Some reports indicated that the Xenos Race used a new type of "shadow blaster" weapon, capable of paralyzing a target fleet's energy systems in a short time, then capturing the ships' crews for use as slaves or experimental subjects.
Even the Imperium's Titan Legion were not spared. In the Vinox system, the Xenos Race used precise biochemical weapons to destroy the Titan Legion' armor filtration systems, forcing dozens of Titans to self-destruct to prevent their technology from falling into enemy hands.
This news shocked the Emperor and the high command of the Imperium, making the Imperium of Man realize that conventional tactics alone could not defeat this alien tide.
The Forge World of Xana became the Imperium's defensive line, situated at a critical location in the eastern The Galaxy / Milky Way, serving as the Core of the Imperium's resistance against the Xenos Race tide.
This planet, controlled by the Adeptus Mechanicus, possessed vast industrial capabilities and powerful Titan Legion, and was considered the Imperium's eastern fortress.
The Second Legion, the Janissaries, the Fifth Legion, the White Scars, and the Nineteenth Legion, the Raven Guard, were the first to arrive here, forming a united fleet to try and prevent further Xenos Race invasion. The Adeptus Mechanicus provided hundreds of thousands of troops and Titan support, while the mortal Imperial Army numbered in the millions.
But even so, the Xenos Race's offensive was unstoppable.
The Imperial side was forced to engage the Xenos Race in an eight-month bloody battle on Xana.
Phase One: The Xenos Race Offensive:
The Xenos Race tore through Xana's defenses with a dual offensive of fleet encirclement and ground assaults. They used massive slave armies to assault ground fortresses, exhausting the Imperium's defensive strength, then dispatched elite "Overlord" warriors to strike directly at the Core of the defensive line.
The Xenos Race's "artificial war satellites" reappeared, projecting high-intensity radiation and orbital bombardment onto Xana, severing communication between the surface and orbit. To maintain communication, the White Scars warriors of the Fifth Legion, supported by cavalry maneuvers and drop ships, desperately protected a narrow transport corridor.
Phase Two: Arrival of Reinforcements:
During eight months of fighting, the Imperial Army suffered immense losses. 3,000 Space Marine and hundreds of thousands of Adeptus Mechanicus troops died in the bloody battle, and Xana's industrial output plummeted to just 20% of its pre-war level. Just as the defensive line was on the verge of collapse, reinforcements arrived: the First Legion, the Dark Angels, and the Fourteenth Legion, the Death Guard, personally led by two Primarchs.
Lion ElJonson's Dark Angels swiftly reclaimed lost ground with their high mobility and tactical flexibility, while Mortarion's Death Guard stabilized the crumbling defensive line with their tenacious defensive tactics.
The combined fleet utilized the First Legion's firepower advantage to conduct continuous orbital strikes against the artificial satellites, ultimately destroying this war tool.
The subsequent Battle of Lax became the climax of the Second Xenos Race War.
In 29864, the planet Lax became the key battlefield of the Second Xenos Race War. This Core world, located in the northeastern The Galaxy / Milky Way, was the last barrier of the Imperium's eastern defense line.
The Emperor personally deployed the main forces of five Legions to participate in this decisive battle, including the Second Legion, the Fifth Legion, the Nineteenth Legion, the First Legion, and the Sixth Legion.
In this battle, four Primarchs were present on the battlefield, including:
Mustafa Sarradin: Known for his wisdom and benevolence, he was urgently appointed "Warmaster" by the Emperor to command the overall situation.
Jaghatai Khan: Responsible for mobile warfare and rapid assaults.
Corax: Led assassination and sabotage missions.
Lion ElJonson: Led the most elite troops to execute critical missions.
Russ: Pierced enemy lines with his fearless offensive capabilities.
The Battle of Lax lasted for a full year, with hundreds of large and small battles occurring during that time. Finally, the main Xenos Race fleet and the Imperial Fleet engaged in a final decisive battle in Lax's orbit.
During the orbital battle, the Xenos Race's warships mimicked the Imperial Fleet's energy frequencies and even infiltrated Imperial lines with disguises, causing heavy losses to the Imperium.
Ultimately, the situation was barely turned around when the Dark Angels' Fleet Commander personally planned the detonation of a damaged battleship near the Xenos Race flagship.
On the ground, Sarradin personally led the Second Legion and the Titan Legion against the Xenos Race's ground forces. At a crucial moment, Sarradin used tactical deception to expose the Xenos Race Warmaster to firepower, killing him. This action directly led to the complete collapse of the Xenos Race ground forces.
However, despite the victory at the Battle of Lax, the aftermath of the Xenos Race still spread deeper into the The Galaxy / Milky Way. Faced with an unstoppable alien threat, the Emperor had no choice but to intervene personally.
That was the Emperor's last resort: the opening of the Labyrinth of Perpetual Night.
Deep beneath the surface of Lax, an ancient golden age relic, the Labyrinth of Perpetual Night, was hidden. This labyrinth was believed to imprison some supernatural entity, possibly even the lost Void Dragon.
The Emperor ordered the destruction of the labyrinth's seals, releasing its terrifying power to combat the Xenos Race. When the Void Dragon escaped its confinement, it transformed into a destructive wave of energy, sweeping away the Xenos Race's fleets and remaining forces.
This measure came at a heavy price; not only was Lax completely turned into a dead world, but the power of the Labyrinth of Perpetual Night also began to cause unstable effects in the surrounding Imperial regions.
After this battle, over 500,000 Space Marine and hundreds of millions of mortal Imperial Army Soldiers died in this campaign, and 19 star systems were completely abandoned. The First Legion and the Sixth Legion were severely weakened after this battle, unable to fully recover to their pre-war peak state.
The Second Xenos Race War marked the destruction of this alien race's large-scale power, but its aftermath continued to affect the The Galaxy / Milky Way.
The Imperium faced internal cleansing operations after the Xenos Race War. Contaminated worlds were abandoned, related data was sealed, and participating Soldiers were permanently forbidden from discussing the existence of the Xenos Race.
To study the lingering threat of the Xenos Race, the Dark Angels founded the Knights of the Broken Claw, specifically to analyze alien technology and tactics, and to guard Xenos Race sites, preventing their resurgence.
Nevertheless, the memory of the Xenos Race was gradually erased within the Imperium, with the remaining historical records sealed deep within Terra, serving as an eternal warning of this catastrophe.
