Compliance of the Autonarchic Union

### Outcome

Planets brought back into Imperial control; Governors all replaced and extensive investigations carried out

The **Compliance of the Autonarchic Union** was a joint campaign by the Warriors of Peace and Shadow Warriors Legions fought during the Halcyon Age, as the Imperium reasserted control over regions that had acquired undue autonomy during the Vanishing. The Autonarchic Union was a collection of planets within the Koronus Expanse that had banded together for protection, but had refused to rejoin the Imperium went officials from Terra arrived. The Jade General, as the new governor of Segmentum Obscurus, oversaw its dismantling personally, and was reinforced by a significant element of Shadow Warriors under their Primarch Rang Talyc, the Ash-Blooded.

## **Events**

As soon as the Conclave of Terra concluded, and the Jade General was appointed governor of Obscurus, he sent word out to all Imperial worlds under Imperial rule that the time of instability had passed and that now it was time for those worlds to put themselves under the governance of the Imperium. The Autonarchic Union council, alongside their generals, rejected the challenge to their authority, and declared full independence from the Imperium. The General gathered over a quarter of his Legion, 16,000 in total, and sent out an offer to any of the Imperial forces who were spreading out to stablise the Imperium to aid him. His call was answered by his brother Primarch, Rang Talyc, looking to vent some of his frustrations about the Conclave on the foes of the Imperium.

The Imperial forces moved in two columns, each led by one of the Primarchs. The larger, led by Rang Talyc, attacked from the south-west, beginning an orbital bombardment of the world of Ramien, where a large concentration of Autonarchic ground forces had been stationed. Leaving the Imperial Army elements to maintain the bombardment and blockade, the Ash-Blooded led the Shadow Warriors fleet in search of the Autonarchic fleet, hoping to catch them in the open with the bait of Ramien and crush them in a decisive void battle. He eventually found his quarry above the world of Yamakor, engaging in a major battle that crippled the Autonarchic fleet, leaving the majority of the ships destroyed. His goal complete, Rang returned to Ramien to begin the orbital assault, starting the brutal fight for control of Ramien.

The second column, led by the General, approached the Koronus Expanse from the south, catching the Autonarchic Union off-guard. They quickly seized the world of Iniquity and established it as a staging post for the campaign. In response, the Autonarchic Union moved their fleet to reinforce the southern planets, stationing around the world of Magoros. Seeing the massing of the Union's strength, Rang Talyc struck at the world of Grace and then sent a vanguard force towards Damaris.

The Union, sensing the chance for a victory that would give them back the initiative, intercepted the vanguard fleet in an ambush, and fierce fighting ensued. However, the Union's hopes were dashed as the rest of the fleet from Ramien arrived, having used their vanguard as bait to draw the Union fleet in. The Union fleet was destroyed in its entirety, with very few vessels escaping and many being captured. The General led his fleet forward rapidly after this, capturing the rest of the nearby worlds of Repton IV, Ritammeron, Magoros and Rain.

The two Primarchs arranged to combine their forces for the final push, and chose the world of Ntharis as the rendezvouz point. The Autonarchic forces garrison the world, which has been fortified in the previous years as the key point in the Union's defence. Along the way, the General brought the world of Damaris into compliance peacefully. The two fleets arrived above Ntharis and combined into a single force, and the two Primarchs began planning for the invasion of Ntharis. At this point, envoys from the Union arrived and begged to open negotiations. The General declined, stating that those who broke their oaths to the Imperium once can never be trusted. The Imperial forces remained in orbit above Ntharis for a week, launching probing attacks and bombarding any clear military targets. Long kept in reserves, the God Engines of the Legio Solachra were to lead the charge, with a landing zone secured by the Warriors of Peace and Kallastin Ogryn Auxilia. The Shadow Warriors and their auxilia landed alongide the Titan Legio, and the combined power of Legiones Astartes, Imperial Army and Titans burst through the Union's defences.

After the Battle of Ntharis, the worlds of the Union began defecting en masse. Small squadrons of ships fanned out and brought many of the worlds back into the Imperial fold, as long as they agreed to hand over their leaders. The last defended by any meaningful way planet was the Union's capital, the world of Dolorium. Though termed the Battle of Dolorium, the end result was never in doubt.

### Aftermath

With Dolorium easily conquered and the war all but ended, the Shadow Warriors departed for their new campaign. Though Rang and the General were not close, they made a show of saying goodbye publicly, showing the Imperium to be strong and united against all threats. Before the two Legions departed, Aliit’Alor Mohammud al’Sayuf requested a private meeting with the two First Captains, Xian Dong and Xian Yun, although the existence of the meeting was not known to anyone at the time. The General and the Warriors of Peace remained behind to settle the situation and begin the process of reintegrating these worlds back into the Imperium.
