War For Lazarus

The War for Lazarus was an Imperial castigation campaign conducted by the unforgiving Invictors of Mars Space Marine Chapter against the rebellious world of Lazarus, one of several recalcitrant worlds, that had foolishly seceded from the Imperium's rule and declared themselves an independent domain. Their rash actions were quickly corrected by the unforgiving Invictors, who made those responsible pay dearly..with their lives.

History
During the turmoil the Imperium faced after countless insurrections and power struggles a group of nobles, backed by their knightly houses, decided to secede from the Imperium and declare their solar system an independent domain. The Guardians of Mars were tasked with brutalizing the populace into submission. The first worlds of the system where easy to take due to their barbaric nature. But the last two were more difficult to take back, one of these worlds which was known as Lazurus. The local PDF had made extensive preparations, utilising their formidable aerial batteries and flak weaponry to take down any vessels that approached too closely to their planet. Many Astartes would lose their lives during the initial approach and subsequent planetary drop assault. Undeterred, the Invictors smashed through the local planetary defences and slaughtered their way to where the rebellious nobles were hiding. The cowering planetary leaders were quick to capitulate and surrendered. In retribution, everyone - including women and female children - were killed. The male children that survived brutal onslaught were brought before the Chapter to be used as potential candidates for the Chapter. Those that did not pass the initial screenings by the Chapter's Apothecaries, Chaplains and Librarians were inducted into local Astra Militarum regiments of nearby worlds.
