Cadia - Legacy of Cadia: Though their home planet was utterly sundered, the resolve of the Cadians has not been broken. Veteran survivors of the last battle for Cadia, along with regiments of their kin scattered throughout the galaxy, now fight even more doggedly against the Imperium's enemies.Whole generations of Cadian Shock Troops are born, raised and trained en route to war zones and soldiers from other worlds with the mettle to withstand Cadian training methods are inducted into their ranks. The mantra "Cadia stands," oft-repeated during the planet's final violent days, has gained purchase within the officer corps and amongst the platoons of the Shock Troops. For Cadia does indeed still stand, they assert, as long as a single Cadian soldier remains alive to fight.The grit and determination with which Cadia was so valiantly defended for all those millennia has long been lauded within the Astra Militarum. The professionalism of the world's soldiers remains influential, not only as inspiration to fuel lurid trench-line tales, but also through tactica penned by Cadian generals that are studied in regimental academies. Rare demobilised regiments of Cadians, granted rights of settlement on worlds they conquered for the Emperor, instill Cadia's legendary discipline into their new societies.Other Astra Militarum regiments model their recruitment and training practices on Cadian doctrine, or seek to equip their forces in the Cadian style. All are eager to emulate a world so heavily militarised that it was said its people were taught how to field-strip and shoot a lasgun before they could even read.Cadia's surviving sons and daughters refuse to allow the destruction of their homeworld to keep them from unleashing the Emperor's wrath on their foes. This dauntless spirit in the face of ceaseless enemies masks several darker sentiments amongst Cadian troops that continue to fight. Widespread hatred for Humanity's enemies has deepened to a zealous degree. Many Cadians see their homeworld's fall as a personal failure and fight all the harder to regain what they perceive as lost honour. Some of those who were not present for the planet's tragic end resent those who failed in its defence but survived, or else feel guilt for playing no part themselves. Others scorn the regiments of worlds they believe failed to aid Cadia in its darkest hour and oppose the use of soldiers from other worlds to be integrated into and expand existing Cadian Shock Trooper regiments, loathe to share the burden of loss with outsiders.In the view of many guardsmen, "the planet broke before the Guard did!" The sacrifice of Lord Castellan Ursarkar E. Creed and those under his command only reinforced for many survivors the bloody-mindedness and hard-faced demanour of the Astra Militarum. The men and women of the regiments of lost Cadia will continue to wade into unremitting firestorms and battle through trenches choked with blood and mud. Alongside defeaning salvoes from armoured behemoths, they will advance into the teeth of enemy fire if that is where their orders lead them.They will do so, again and again, continuing to fight until the day every Traitor in thrall to the Dark Gods is defeated at last and their world avenged a thousand times over.
