Chogoris, named Mundus Planus in the cold registers of Imperial cartographers, is a green and living world of boundless grassland steppes, jagged mountains, and wide skies, a rare beauty amid the dying stars of the galaxy. Across its plains roam nomad tribes who live and die in the saddle, following their herds and warring among themselves in a culture built on speed, honour, and the hunt. Great hawking-birds wheel above the grasslands, and the tribes reckon a swift horse and a keen blade the truest measure of a warrior's worth.
Before the Imperium came, these plainsfolk knew nothing of the wider galaxy, and their warring khanates might have remained forever locked in feud had a child not fallen from the stars into their midst. That child grew to become the primarch Jaghatai Khan, a warrior of such genius and ferocity that he united the tribes beneath a single standard and carved from the chaos of Chogoris a mounted empire.
When the Emperor at last arrived, the Khan recognised in Him a greater conqueror still, and pledged his people and his warriors to the crusade among the stars. From the finest riders and hunters of Chogoris are drawn the aspirants of the White Scars, a Chapter that carries the culture of its homeworld into the void.
Swift, elusive, and cunning, the sons of the Khan trade the horse for the assault bike and the jetbike but keep the soul of the steppe, striking from nowhere and vanishing before the foe can answer, as befits warriors of the Adeptus Astartes shaped by so wild a world. They value freedom above ceremony and the hunt above the siege. To fight the White Scars is to fight the wind itself, and on Chogoris the wind never stops.
