Lord of the Red Sands is the ninth short story published in the Horus Heresy that was not originally part of an anthology novel. It was first published as part of The Imperial Truth exclusive anthology novel and also released separately as an e-book. It is also included in Angron collection and in the War Without End anthology novel.
Angron, gladiator-Primarch of the XII Legion, is renowned across the galaxy for his savagery and brutal martial code. But amidst the ruins of Isstvan III, even as he slaughters his own wayward sons, he finds a unique serenity in the carnage of warfare...no matter whose blood he spills. And for what does the Eater of Worlds hunger above all else? Nothing more than freedom.
