The Horus Heresy begins on a note of hope and unity. The Imperium of Man, led by the Emperor, had embarked on the Great Crusade to reunify the scattered worlds of humanity under its benevolent rule. At the heart of this crusade were the Space Marines, genetically engineered superhuman warriors divided into different Legiones Astartes, each with its own distinct character and heritage. The Primarchs, twenty superhuman sons of the Emperor, served as the commanders of these legions. Among them was Horus, the most favored of the Emperor's sons, who would eventually become the Warmaster, the supreme commander of the Space Marine Legions.
