As the Emperor travels the galaxy at the head of his Great Crusade, few events are as important as rediscovering his scattered sons, the Primarchs, and bestowing them as the masters of their Legions. United, a Legion becomes a reflection of its Primarch, both in his strengths and his flaws. For the Twelfth Legion, once the War Hounds and now the World Eaters, the line between strength and flaw is almost impossible to separate.
