Adrellian Massacre

The Adrellian Massacre was the overall destruction of much of the Chapter, by the Steel Brethren warband of the Heretic Astartes. The first attack began from moment the Steel Brethren had organized in the sewers of Droken, where the main headquarters of the Chapter was stationed in the Great Citadel. The First Battle of the Citadel began as hordes of daemon engines cracked through the city streets, followed by the bolter and plasma of Heretic Astartes.

The heavy-walled bulwarks on the towers forced the First Battle of the Citadel to conclude in Imperial Victory. By this point word was spreading across the world of possible invasion, but with attacks across the world the Chapter was unable to organize for the first two days of battle, with the city of Elisia being overrun by day break. The newly appointed Chapter Master, Vangor, detailed a plan of defense that concentrated the cities of Drasmis and Droken, using the peninsula both hives were situated upon to create a natural barrier as the Chapter and local garrison moved to secure battle lines between both cities. With the cities of Portitum and Elisia abandoned, the Steel Brethren moved to destroy the remaining and beleaguered defenders. The Second Battle of the Great Citadel saw the onslaught of the warband. Vangor entrusted the defense of the Citadel to Kathe Mackius, Captain of the Fifth Company. During the onslaught. it was Mackius who bled with his men before the walls of the Citadel, under the horrific onslaught of the siege, as the towers began to collapse and the great works of their Chapter burned and looted. One hundred Astartes were stationed in the Citadel, only twenty remained when relief from the Honor Guard of the First Company arrived.

By the time of their arrival, the gene-vaults of the chapter were looted and Mackius himself was founded broken and bloodied, his arm and leg ripped as he stood with chainsword in hand, surrounded by tens of Steel Brethren. These great stands occurred all over the world, with battle brothers laying their lives to secure the battle lines. The most famous of these being the Battle of the Lost Bastion. In the underhive of Drasmis, the Chapter, after recovering the stocks from the gene-labs in the Interdix Medicae, fight their way through massed Traitor forces, running a deadly gauntlet through the underhives of the sub-system sewers and industrial growth in order to deliver the gene-stock off world. In the underhive, the devastator marines of the Second and Fourth Companies stood their ground, electing to sacrifice themselves in order to bide time for the Medicae.

Armed with plasma cannons, it is said that their blue hues of Emperor's justice never missed, slaying their traitors by the droves before succumbing to the onslaught. Before the final battle brother was slain, Franz Draken bid the traitors one last folly and detonated a cash of explosives under the hive tunnels, causing the section of the industrial mechanicum to collapse and close off the remaining under hive. But despite their effort, the Paragons of Dorn were pushed to the last space port when the unthinkable happened. The world itself was was consumed by the warp, its surface was broken and ripped from the material realm.
