The Faeburn Vanquishers are a Militarum Regimentum of the Astra Militarum who emulate the Cadian Shock Troopers. The drilled precision and ardent resolve of lost Cadia's regiments have been emulated across countless Imperial worlds, with many Militarum Regimentos receiving training from Cadian infantry and tank officers. Cadian-derived tactics and uniforms are therefore seen upon battlefields throughout the galaxy.
The Vanquishers hail from the honeycombed caves of the world of Faeburn. Since the opening of the Great Rift, a strange phenomenon has filled Faeburn's skies. The hallucinogenic pattern, known as the Aurora Illuminato, forms shapes and faces, which Faeburn's devout believers in the Imperial Cult see as signs sent by the Emperor. However, the images bring nightmares as often as they bring solace.
