Ulandus' Vengeance

Ulandus' Vengeances is the name of a joint-Imperial castigation campaign conducted by the wrathful Emperor's Reapers and their allies from the Ultramarines Space Marine Chapters against the forces of the vile Word Bearers Traitor Legion.

Background
Two thousands years after the Ulandus slaughtered a warband of the Word Bearers Traitor Legion, the vile sons of the Daemon Primarch Lorgar returned to the planet to conduct a powerful ritual by attacking several neighboring planets to gather Imperial civilians to utilise in ritual sacrifice. Upon hearing about the warband's return, the Chapter eagerly sallied forth to finish what they started two millennia earlier, to ensure once and for all, that the Traitor Astartes would not escape their wrath. Acquiring the aid of the Ultramarines Chapter who still bore the memories of the Shadow Crusade and the Calth Atrocity during the Horus Heresy, they eagerly joined the Emperor's Reapers on drawing out the enemy forces. Meanwhile, the Emperor's Reapers focused on any fortifications and enemy movements to cull and engage in flanking strikes on the Traitor Astartes. the Ultramarines strike force fought alongside the Reapers during the 6 year long campaign, which finally ended with the eradication of the Chaos warband. In the aftermath, the Imperial planet was decorated with scattered pikes of the decapitated heads of the Word Bearers Heretic Astartes, left as a dire warning on the planet to those that followed the Dark Gods.
