Chaemos Crusade

History
The Chaemos Crusade was a Imperial campaign that took place within the Ork empire of the notorious Ork Overlord Krotzmar Skullspitta. Chaemos, the capital world of this empire, and the site of the final assault, lay in the Persepolis System of the galaxy's Pelegron Sector. The Sable Lions' employed the use of their 1st Kárdake to destroy the Ork Empire by removing its head. The Wardens of Orasks' 1st Crusade Fleet, supported by the Imperial Army of the Persepolis Janissaries and other forces such as the Titans of the Mechanicum, attacked the outer planets of the Pelegron System.

This offensive was a decoy, though it proved quite effective. Many of the Orks' starships rushed to prevent the attacks on the outer planets, leaving the central world dangerously vulnerable and exposed to the waiting main body of the Imperial forces, led by the Astartes of the Sable Lions Chapter. The Sable Lions' Chapter fleet headed straight for this central world and more specifically for Krotzmar's fortress-palace.

At the height of the campaign, Caliph Sargon Akkad "The Great Lion" and his Terminator-armoured elite Caliph's Ashu successfully confronted the Overlord and his retinue of Nobz. With the death of its leader, the Ork forces collapsed into infighting as was their wont and the battle for Chaemos soon became a massacre. The remainder of the Pelegron Sector was subdued by the forces of the Crusade and returned to Imperial rule within the year, as the Ork empire had completely fragmented upon hearing of its master's death once the various Nobz declared themselves the new Warlords and fought each other for control. With Krotzmar's termination, the nascent Ork empire self-destructed, and the xenos that were not hounded into the mud of Persepolis' System vast battlegrounds would be hunted down across hundreds of star systems.
