M41 · The 13th Black Crusade

The Fall of Cadia

The fortress world that had guarded the Eye of Terror for millennia was broken at last, its defenders defiant even as the sky fell upon them.

The Fall of Cadia is the darkest hour of the 13th Black Crusade and one of the great catastrophes of the 41st Millennium. For countless generations the fortress world of Cadia had stood as the Imperium's foremost bulwark against the Eye of Terror, its people bred to war from the moment of birth, its continents bristling with fortresses raised against everything that boiled out of the warp.

When Abaddon's vast host descended, the Cadian Shock Troops fought with the iron discipline that had made them the most respected soldiers in the Imperium, reinforced by Space Marines, the massed guns of the Imperial Navy and even the miraculous Living Saint Celestine. Lord Castellan Ursarkar Creed marshalled the defence with genius, but the Despoiler's numbers were beyond counting, and the daemon-haunted tide could not be held back forever. Whole regiments were consumed holding a single wall, and still fresh horrors poured from the Eye of Terror without end.

The true blow was aimed not at the armies but at the ancient necron pylons buried across the planet, arcane structures that had for aeons quietly held the local warp in check. As the traitor Legions toppled the pylons and drove a captured Blackstone Fortress into the world itself, Cadia's death became a certainty. Even as the crust split and the burning sky came apart above them, the defenders held their lines, and the defiant vow that Cadia stands was spoken over a world already dying beneath their boots.

But Cadia did not stand. Its destruction helped unleash the Great Rift and scattered its hardened survivors as refugees and vengeful soldiers across a broken galaxy, carrying their loss with them wherever they went. The full account of that dark day is told in the chronicle of the Fall of Cadia.
