Purge of the Exodus Sector

The Purge of the Exodus Sector was a massive Imperial castigation campaign carried out by several bellicose and savage Chapters of the Adeptus Astartes, including the Blood of Vulkan, Black Templars, Carcharodons, and the Minotaurs, to cleanse the fallen Exodus Sector from the Forces of Chaos.

Background
Following a massive warp storm that caused the Exodus Sector to become cut off from the rest of the galaxy, seven Adeptus Astartes Chapters were sent to quell the invading Forces of Chaos. Unfortunately, these Chapter later fell to the corrupting influence of the Ruinous Powers. The High Lords of Terra assembled a large Imperial castigation strike force to purge the Chaos-corrupted Chapters and cleanse the fallen sector. These Chapter included the bellicose Blood of Vulkan Chapter, the zealous Black Templars, savage Carcharodons and unforgiving Minotaurs Chapters.

During the forty-year long campaign, most of the Blood of Vulkan Chapter defended and help evacuate several Imperial worlds, while Chapter Master Nenker and the Veteran 1st and 2nd Companies assaulted the Traitor forces. During the Battle of Sigis 3, the Blood of Vulkan Chapter fought against a Renegade Chapter, known as the Blood Messengers, who were dedicated to the Blood God Khorne. With most of the world devoid of life from orbital bombardment and the remaining forces mainly located within the fortress-monastery, the Blood of Vulkan launch an all-out assault against the Renegade Chapter's citadel. A vicious battle ensues, but in the end, the Blood Messengers are utterly wiped out by the merciless Blood of Vulkan.
