Undertaking to Sirroij

The Undertaking to Sirroij was a retribution campaign launched by the zealous Castigators Chapter against the recalcitrant mining world of Sirroij, after it had fallen into insurrection and open rebellion. Miraculously, very few lives are lost, as the Castigators commander in charge is able to come to peaceful resolution with the striking miners.

History
Chapter Master Quintilius dispatches the 3rd Company to the world of Sirroij after the Castigators receive word that the planet's promethium miners had lain down their tools. The Castigators had somewhat of a stake in Sirroij - the planet's mines provided the Chapter with much of its promethium requirements. Industrial disputes on Sirroij could compromise the Castigators' ability to wage war. Captain Ramus, the Chapter's Chief Victualer, was tasked with resolving the Sirroij by any means necessary. To achieve those ends, the 3rd Company and Captain Sirius were to support him.
